Why is Diet Soda Bad For You? The Truth About Diet Drinks

Boy Drinking Soda Through StrawHow many people do you know who lost weight simply by switching from Coke to Diet Coke?

Probably not many.

That’s because unless followed by other lifestyle changes, choosing diet drinks is absolutely useless.

Diet Soda – What Exactly is it?

Diet sodas are carbonated beverages.

Instead of sugar, they are sweetened with artificial sweeteners like aspartame, cyclamate, saccharin, acesulfame-k or sucralose.

Almost every popular sugar-sweetened beverage on the market has a “light” or a “diet” version… Diet Coke, Pepsi Max, Sprite Zero, etc.

These drinks are calorie free, which technically should help people lose weight and prevent sugar-related diseases like metabolic syndrome and diabetes.

However, the evidence for these beverages having any use is completely nonexistent.

Diet Soda and The Metabolic Syndrome

The metabolic syndrome is a group of risk factors for disease that often occur together and raise your risk of diabetes, stroke and heart disease.

It is defined as having at least three of the following:

  • Abdominal obesity (belly fat)
  • High fasting glucose
  • High triglycerides
  • Low HDL cholesterol
  • Elevated blood pressure

Drinking “calorie free” beverages instead of sugary ones does not appear to be helpful against the metabolic syndrome.

In a study published in the journal Circulation in 2008, which followed 9,514 people for 9 years, drinking artificially sweetened beverages was associated with a 34% greater risk of developing the metabolic syndrome (1).

Another study found a 36% increased risk of metabolic syndrome and a drastically increased risk of diabetes in diet soda drinkers (2).

Bottom Line: Observational studies show a correlation between diet soda and the metabolic syndrome, which can lead to serious diseases.

Diet Soda, Depression and Preterm Delivery

There is an association between diet soda and depression

In a study of 263,925 adults aged 51-70, individuals who drank soda were 30% more likely to be diagnosed with depression over a period of 10 years.

The link was stronger for diet soda than regular soda (3).

Diet soda is also associated with preterm delivery.

In a study of 59,334 pregnant women in Denmark, 1 serving per day of diet drinks was associated with a 38% increased risk of preterm delivery. 4 servings per day increased the risk by 78% (4).

Bottom Line: Diet soda consumption is strongly associated with both depression and preterm delivery.

Diet Soda and The Risk of Type II Diabetes

Type II diabetes has increased at an alarming rate in the past few decades and now afflicts about 300 million people worldwide.

This disease is highly associated with obesity and sugar consumption, so some would argue that replacing sugar-sweetened beverages with calorie-free drinks would help.

However, there is no evidence of these drinks being helpful against diabetes.

A study of 6,814 individuals aged 45-85 years, daily consumption of diet soda was associated with a 67% increased risk of type II diabetes (2).

In another study, 66,118 French women were followed for a total of 14 years. Women who consumed the most diet drinks had a 121% greater risk of developing type II diabetes (5).

Data analysis from two large Harvard studies revealed that diet drinks raised diabetes risk in women, but not men. Each daily serving increased the risk of a diabetes diagnosis by 6% (6).

Bottom Line: The association between diet soda and diabetes is very strong, especially in women. One study showed more than a doubling in risk.

Diet Soda, Obesity and Weight Gain

The main reason people switch to diet drinks is to cut back on calories in order to lose weight.

Unfortunately, it doesn’t seem to work.

In a study of 3,682 individuals from San Antonio, Texas, consumption of diet soda was associated with double the risk of becoming overweight or obese (7).

Other prospective studies also show an association with artificial sweeteners and weight gain (8, 9).

However, we do have one randomized controlled trial, where 318 individuals were split into 3 groups: A control group, a group that replaced sugary soda with water and a group that replaced sugary soda with diet drinks (10):

At the end of the 6-month study, there was no significant difference between all three groups. In this controlled trial, diet soda didn’t make things worse, but didn’t make them better either. Neither did water.

I’d like to point out that many short-term feeding trials show that artificial sweeteners can increase appetite and food intake in the short-term compared to sugar, but other studies show the opposite effect or no effect at all (11, 12, 13, 14, 15).

Bottom Line: Observational studies show a strong link between diet soda and obesity, while one controlled trial shows no effect at all.

Take Home Message

Many of the studies above are so-called epidemiological studies, which can not prove that diet drinks caused anything. Such studies can only show an association.

Whether diet soda can cause harm or not has yet to be proven in controlled trials, but it is clear that there is a strong statistical association between diet soda and disease.

One possible explanation for the link is the fact that people who are already gaining weight are more likely to turn to diet drinks.

There is of course, no physiological need for these drinks in the diet, although many people tend to enjoy them.

I personally choose to avoid diet soft drinks, mainly because I don’t like the way I feel when I drink them and prefer to keep my body as free of artificial chemicals as possible.

  1. Interesting article.
    Now I wonder as an endurance athlete who enjoys a diet coke a few times a week, should I switch to regular coke?

    I monitor my calorie intake (and burn) and aim for a 500 – 1.000 kcal deficit. Which means I would need to reduce food to account for the difference from 0 kcal diet to regular soda. Though this seems counter-intuitive as soda are empty calories.

    Ideally I would drop soda completely, but you gotta treat yourself sometime.

  2. I definitely agree with this. I tried losing weight once simply by switching to diet drinks and it did nothing for me, I just kept gaining.

  3. Cory Stansbury says:

    Kris,
    While I normally agree with the stuff you say, I’d say this article is a case study in “correlation doesn’t equal causation.” I don’t think you can draw good conclusions from this data.

    • I agree completely. Too many of the studies that are used to say artificial sweeteners are correlational. I think that creates ALOT of confusion. Think about it this way; who do you usually see drinking “diet” beverages… most of the time it is people with weight problems. This does not necessarily mean that sweeteners are causing people to be like this. In fact, one could easily argue that these people are drinking diet beverages because they are aware of their condition.

      A lot of confusion and Claims made by reverse causality.. A large flaw in a correlational study.

      • I can’t help but wonder just why this article was even published except for the fact that there is no cause for suspecting any bad effects for most diet drinks.

        Nothing can take the place of a nice ice cold, fizzy to point of taking the skin off of the back of my throat when I am thirsty. Sugar is the culprit and everyone can see that on the labels. Young people buy the huge bottles of sugared Mountain Dew and habitually storm their systems with excessive sugar and calories.

        Strangely they seem to be fairly over weight people even though young. I like beer much better than liquor but I simply don’t drink enough to cause weight gain even though I am a hog for eating.

    • I agree with all this information here. I stopped drinking Diet coke because of how I felt. I stop drinking it for two weeks.

      I was offered a Diet Mountain Dew. After ten minutes of drinking it, my heart rate was up, my throat felt like it was closing, I was dizzy. I felt terrible. I won’t ever have any soda again. Besides the ten pounds I put on around my belly.

  4. “Bottom Line: Observational studies show a massive correlation between diet soda and the metabolic syndrome, which can lead to serious diseases.”

    The most likely explanation is that diet soda is chosen by people who have problems with they weight, hence the correlation between being overweight, and drinking it. Also this study:

    “However, we do have one randomized controlled trial, where 318 individuals were split into 3 groups: A control group, a group that replaced sugary soda with water and a group that replaced sugary soda with diet drinks (10):

    At the end of the 6-month study, there was no significant difference between all three groups, indicating that the diet drinks had no benefit at all.”

    Gives what conclusions that drinking soda is as good as drinking water for weight control?

  5. Switching to diet soda certainly wasn’t a magic pill for me and what you notice on low carb forums especially is that people don’t replace their favorite sweets, they simply switch the sugar out. This is the main reason why I moved away from low carb communities, they may not eat carbs but they still eat lots of processed junk and never really address the sweet tooth issue. A diet soda is still full of chemicals and crap that cannot be good for you. In any case, I ended up cutting all sugar out, artificial or not and wont be looking back. Now I need to address my salt addiction.

  6. Helgi S. Karlsson says:

    I don’t understand why you continue your campaign against diet drinks.

    You know as well as I do that there is still nothing that proves the harmful effects of those sweeteners, unless taken in huge dosages (like everything else). As you know, those strong associations with harmful effects most often have a lot, if not everything to do with other lifestyle behavior, that is, people drinking diet soda are often compensating for other unhealthy lifestyle behavior which may very well be the major, if not the only cause behind the bad effects. Also, bad eating habits follows weight gain, followed by depression and other mental issues etc. Realize the complexities of association. Don’t fall into the “narrow minded science” gap.

    With the complexities of association, you should really focus on something else to write about because you are not stating any information of worth here. Without proven facts, which most of your other great articles are based on (the low carb ones are excellent), this becomes a pointless read, because at the end of the day, the next study can tell us exacly what I’m telling you now, that it is a factor of association that is to blame, not the sweeteners themselves.

    Also, you seem to counter your own arguments with this article. You are campaigning against non-sugary drinks, not proven to be harmful, even though there are hundreds, if not thousands of research articles on the issue (with every one that can’t prove it’s harmful effects, the finger is pointed further towards the association, not the sweeteners) while most of your other articles are against sugars and other bad carbohydrates, how we should avoid them at all costs.

    You have proven yourself as a man of science. Then realize the faults and complexities of association and stop campaigning against something that is not really proven to be harmful, especially when it seems to be one of the few substitutes available in a sugar loaded world.

    Also, write an article on Xylitol, a natural sweetener (not an artificial one like aspartame) which looks and tastes like a normal sugar, and has been studied extensively and has shown some unique health benefits like natural cooling and moisturizing. It has been the best thing that has happened to me and my girlfriend while carrying on a low carbohydrate diet. It allows for ice cream, caramel sauce and basically everything else, when combined with coconut flour (0 carbohydrates).

    Otherwise, good job on most of your articles. I continue to enjoy them.

    Regards, Helgi S. Karlsson

    • What I hate is companies try to force artificial sweeteners on us. I bought a can of fruit that claimed “No Added Sugars”. I just thought that they left it to nature. I opened it up, ate a piece, could tell there was sucralose in it, checked the label and there was and I wondered, why would someone feel the need to make pineapple even sweeter than it already is. I hate that I have to read labels all the time to make sure they aren’t sneaking that stuff into my food.

  7. Well what about plain old carbonated water? No flavoring added. I have used this to replace my need to splurge on sodas and works very well. Ingredients are water and carbonation only. Is this okay? How bad is drinking carbonation?

  8. Basically this article confirms me further in my decision. I do not drink coke/pepsi or whatever – but when I triple I go for the real stuff, with sugar as “nature” intended coke/pepsi to contain :)

  9. How often these observational studies conclude:

    People who drink diet soda are obese, therefore drinking diet soda causes obesity. Maybe these people also consume fattening foods and that is why they are obese.

    Aside from the fact that there is nothing natural about diet soda, we really do not have any good scientific evidence to demonstrate causality at this time. More research is needed.

  10. I quit drinking diet coke/pepsi when I was told you can clean glue off tile (after laying tile) and other gooey substances with either product and that it is very hard on your teeth. Reason enough but read the ingredients…..nothing worthwhile.

  11. Thanks for the comments, everyone. I seem to have let my confirmation bias get the best of me. I have now updated the article and made it more scientifically accurate.

    It is true that there are other possible links for the statistical associations and that controlled trials generally trump epidemiological studies.

  12. Kris Gunnars – Thanks for posting and updating this important topic. I enjoy following here and http://www.docsopinion.com/.

  13. Paula Hogarth says:

    What is the best cold drink other than water?

  14. Kenneth says:

    I’m a type 2 diabetic. I go to my doctor every 3 months to check my A1C level. In February I went to the doctor and had a full blood work. It came back and my tryglycerides were “through the roof” as my doctor said. I have been drinking diet drinks for about the last 3-5 years.

    So now I have to take another medicine to lower my trygliceride level. So thank you “diet drinks.”

    • The best way to lower both blood glucose and triglycerides is to cut back on carbohydrates like sugars and grains.

      Needs doctor supervision though, because it can lower your need for medication.

      • Kenneth says:

        My Dr. told me to drink only water, real lemonade or Crystal Light. Does that sound right?

        • If the lemonade doesn’t contain sugar, then sure.

        • Kenneth, for gout, drink cherry juice or eat dark cherries. Sounds too easy to be true but the body is wonderfully made. The cherry juice can be purchased from a health food store. I usually buy it in concentrate and add some to my water. The gout goes away in two to three days.

  15. Best advice ever to those wanting to lose weight- Just don’t drink pop at all. There’s absolutely nothing nutritional about it. Drink more water instead and weight will come off eventually. Add in regular exercise and a smart diet too.

  16. Jan Yoder says:

    IMO–there is some relationship between cancer of the tongue and salivary glands and diet soda. I drank, on the average 4 or 5 per day for 10 years.

    Yes, I did lose weight! But, after having a malignant tumor removed from the base of my tongue, now I cannot drink diet drinks at all. Anything diet will cause a burning of my tongue, while sugared soda does not. Just an interesting sideline.

  17. Colette Barr says:

    Hi – an interesting read and discussion. I am looking for motivation and shocking facts to stop my horrendous diet coke addiction. I am a slim, relatively fit and very healthy female in my mid 30s. I have been drinking a diet coke every morning of my life for the last 18 years. Sometimes I have 2 but never more. I also drink minimum 2 litres of water every day.

    I’ve read terrible things about diet drinks and KNOW I should not be drinking them but I honestly cannot kick the habit. I am a strict vegetarian and can easily cut items out of my diet but I struggle so badly with this issue. I think it’s because I am not fat and not unhealthy and drink water that I believe I don’t need to give up but it cannot be good for me. I would really like some more terrible tales of diet coke please… make me stop!

    • Hi Colette,

      I have never responded to a forum before, so the universe has brought me to this forum :)

      Your comment summed up my situation perfectly – I was exactly the same (EXACTLY)… I thought I was reading my own bio! If anything is different, it would be the amount I was drinking (a lot more than you, starting at 6am each day). Just over 12 months ago I gave up diet cola, COLD TURKEY. I had tried for years to “cut back”, “wean myself off it” and it was 100% unsuccessful.

      Cold turkey (and the personal commitment to never, ever again take another sip) was the only answer. I felt I might die for the first 4 days, it was simply torture… The next few weeks were full of psychological cravings you wouldn’t wish upon your worst enemy… AND THEN IT GOT BETTER :)

      Now I feel sorry for ‘addicts’ loading up their trolley at the supermarket just as I used to. I have never felt less anxious in my whole life. And every month that goes by I just feel better.

      I have 3 key tips:

      1) Go cold turkey on the first day of Autumn. Simply because you will crave it more when you are thirsty and the weather is hot. Use winter to your advantage.

      2) Drink water 100% instead. Every time you feel the crave, DRINK A BOTTLE OF WATER STRAIGHT AWAY, then tough it out! My staff and I have a little joke, every time they pop out for refreshments and ask me if I would like anything, I always say Diet Coke, and they bring me back a bottle of water :) it’s cute and fun and the humour really helps.

      3) Willpower… There is no substitute. Just do it and stick to it. Just say “no”… It will get easier, I promise – PROMISE.

      GOOD LUCK, I know you can do it.

  18. Sabrina says:

    I drink an occasional diet pepsi maybe twice a week, but then I will make sure to drink a little more water after drinking it. I love my pop but I don’t have to have it all the time. I don’t like water, but I will drink it and crystal light. Everything doesn’t work for everyone because every ones body is not the same.

  19. Correlations mean nothing. Hard proof or stop confusing people and making statements that carry no weight.

    The only real side effects of diet soda that have been proven are dental in nature, and they apply to both regular and diet.

    Diet sodas do not cause obesity. Weight loss/gain is a simple mathematical problem…calories in vs. calories out.

    http://examine.com/faq/is-diet-soda-bad-for-you.html

    • Correlation doesn’t prove causation, that is true. However, the associations are very strong and very consistent among studies. They show that people who drink diet soda are much more likely to become obese, diabetic and get metabolic syndrome over the coming years. I don’t think they should be ignored.

      There is a possibility that the sweet taste plays tricks with the mind, causing an automatic increase in food intake. That way, diet sodas may make people eat more calories overall.

      There are feeding studies showing that artificial sweeteners can impact food intake.

      Here is a good paper on this: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2892765/

      A small bit from the paper:

      “Preload experiments generally have found that sweet taste, whether delivered by sugar or artificial sweeteners, enhanced human appetite. Aspartame-sweetened water, but not aspartame capsule, increased subjective appetite rating in normal weight adult males. Aspartame also increased subjective hunger ratings compared to glucose or water…”

      If you count calories and eat a controlled diet, artificial sweeteners won’t affect your weight. But if you’re eating ad libitum and let your appetite govern when and how much you eat, then it might make you eat more and gain weight.

      • I think the internet’s been really good at making people learn about “correlation does not equal causation” or some people take it to the extreme and say correlations are junk. Dig deeper and some will make a claim about the confounding factors.

        To play devil’s advocate, researchers are (or should be) well aware of these OBVIOUS confounding factors and will account for them.

        To make a counter to that counter… epidemiology falls apart when you can’t account for what you don’t know… and there’s lots potentially that we don’t know we don’t know.

  20. Correlation alone does not make these unhealthy drinks; but neither does it make them healthy. The fact is, those most likely to guzzle gallons of diet sodas no doubt make other bad eating choices and that’s what leads to obesity, heart disease and diabetes. For those people with a healthy diet and self control, a diet soda drink once or twice a week is a great option as a zero calorie treat – how many other treats are zero calorie AND reduce your sugar craving?

  21. Diet soda, what is it? A drink made of carbonated water, probably safe by the author, flavored and sweetened with an indigestible sugars. Artificial sugars are not assimilated into our bodies. They are excreted. These drinks are calorie free, which means that it can help people lose weight if other lifestyle choices are managed properly.

    Metabolic Syndrome (MS) a disease defined as having at least three of these conditions:
    > Abdominal obesity (caused by consuming excessive amounts of real sugars which the body stores as fat)
    > High fasting glucose (caused by consuming large amounts of sugars over a long period of time)
    > High triglycerides (caused by eating saturated fats)
    > Low HDL cholesterol (caused by unhealthy habits like eating little fiber and leading a sedentary lifestyle)
    > Elevated blood pressure (caused by taking life too seriously, consuming lots of salt and not exercising)

    How in the world do we conclude that drinking “calorie free” beverages have anything to do with MS? That is, other than having an unhealthy lifestyle that may or may not include drinking diet drinks?

    Note: “observational studies cannot be used as reliable sources to make statements of fact about the ‘safety, efficacy, or effectiveness’ of a practice…”

    The correlation between diet drinks and depression, type II diabetes, obesity and weight gain (all caused by over eating with or without diet drinks) will easily collapse to similar analysis.

    Note: A randomized controlled trial (RCT) is a specific type of SCIENTIFIC experiment, and the GOLD STANDARD for a clinical trial.

    Take Home Message. Observational studies CANNOT be taken seriously when an RCT has demonstrated diet sodas have the same effect as water. Have a healthy lifestyle if you want to avoid MS, Type II diabetes, depression, obesity, weight gain and even premature delivery.

    • You’re right, but artificial sweeteners have in some studies subconsciously lead to increased food intake (calories in), even though they don’t have calories themselves: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2892765/

      The observational studies definitely have major limitations, but when there are strong, highly significant, consistent correlations, then I think it’s worth mentioning. Be aware that these studies usually at least try to correct for confounding factors like exercise and other dietary habits, even though it doesn’t always work.

      These studies are done in the context of a western ad libitum (eat all you want) diet. They probably won’t have any effect in the context of a controlled diet.

      I’m not fully convinced that artificial sweeteners are safe. They are at the very best useless, no RCTs I’m aware of show that replacing sugar sweetened beverages with artificially sweetened beverages leads to weight loss.

      • People’s inability to control what they eat/lack of willpower/rationalizing a trade-off, whatever you want to call it should not be mentioned in the results of a study or even hinted at. Once you get into the realm of adding your opinion to the outcome of a study then you draw the results of the whole study into question..IMHO.

        If the goal of the study is the artificial sweeteners themselves, then that’s what the results need to be about as well.

        To quote Joe Friday, “Just the facts ma’am.” :)

        • What?

          Saying that calorie intake is purely a function of willpower is ridiculous… IMHO.

          But it’s a common belief among people who can do so easily, I suppose it helps them feel morally superior to those poor weak-minded obese folks.

          The way the body and brain control energy balance is incredibly complex. There are genetics, biochemistry, hormones, environment and a ton of other factors involved.

          Some people can affect the outcome with willpower alone, but it is rare and most can not.

          • It was most definitely not easy for me to make the lifestyle change I did to lose 130 pounds. I come from a family where everyone’s overweight, and I saw what was happening to them and made a decision that I was going to change.

            I firmly believe that it is a matter of willpower. I know people classify themselves as emotional eaters and whatnot. No one’s holding a gun to their head making them eat. People make their own choices on what kind of food they are going to eat and how much of it they will eat.

            There are alternatives to stress relief besides eating.

            It takes exactly what I said above, a decision to make a lifestyle change. There are plenty of support groups out there that can greatly assist with that.

          • I’m glad to hear that you were so successful, too bad that the majority of people fail despite their best intentions.

  22. I am a big diet pop drinker. I have been for thirty years since I was anorexic. I’m no longer anorexic, but I still drink diet pop because I don’t like to put unwanted calories into my body. I am tired of people scolding me for drinking diet pop.

    In addition to diet pop, additives in foods, chemicals in our plastics, sugar in pop, dyes in fruit snacks, caffeine in energy drinks, synthetics in prescription pills – almost everything we inject in our body in today’s world has some harmful effects. Other than diet pop, I raise my own vegetables, eat meat we raise on our farm, drink milk from our dairy goat, and last fall I ran a half-marathon.

    I think I’m wise enough to choose what things I want to put inside my body. My parents smoked while I was at home and I took in second hand smoke for 20 years living with them. They are now 80 years old and in good health. Other than having four children, I have not been in the hospital – ever – for health problems.

    If we allow people to smoke nicotine, drink vodka, and smoke marijuana legally in several states now, we need to focus on more the harmful effects of obesity and addictions. I’m a big girl. Let me and my diet Coke alone.

  23. C’mon children, everything in moderation and you’ll be fine. This is true for almost everything in diet.

  24. Is iced tea with Sweet and Low as bad as diet coke?

  25. I’m sorry, I really can’t agree with this. Of course you can never lose weight by just switching soda, you have to make other changes. Diet coke has helped me lose TONS of weight simply by tricking me that I’m drink something more filling and a little energy boost from the caffeine. (But diet coke isn’t the only reason I’ve dropped weight!)

    I really don’t believe diet coke is linked to diabetes or depression either. There’s no way in the next ten years I see myself becoming diabetic or ‘depressed’ because of what cola I decided to drink when I was 15.

  26. I’d like to say that this article focuses on how people who “diet” by drinking diet coke aren’t helping themselves, but in my case, I just like the taste of diet coke better than regular coke.

    The article aside, I get a lot of ridicule for liking the taste of diet coke and all of these studies that these people have been looking at to justify how it’s unhealthy just point out that it’s not a solution.

    Can anyone point out an argument telling the exact chemical differences in the two sodas and how they directly affect chemicals in the body (I’m not looking for a video on turning an egg green)? Thanks.

  27. I have struggled with this issue of drinking sodas. I am 65 years old, a little over weight (gained 30 lbs over the last 20 years), but attribute this to lifestyle. I have drank sodas all my life and diet drinks since the 80′s. I am now border line diabetic, but I easily control this with my diet.

    Calories, be sugar or otherwise makes a big difference for me, so I don’t watch what I eat, but how much. I personally don’t believe a sugar, or diet coke is any worse than apple juice and all the other sweet juices.

    The other day my wife came home with a Tropicana Fruit drink, that was 100% juice, but guess what, it has 40 grams of sugar. How can that be better than a Coke?

    I do not worry about myself, but do worry about my 7 and 10 year old boys. I try to limit them to no more than one a day or less. I pretty much think anything in moderation is OK. Just be sensible with it.

  28. David Banner says:

    I’m 39… have been drinking diet pepsi/coke to the absolute extreme for at least 15 years. Literally on average 64 to 96 oz a day (2-3 32 oz’ers). I go for blood tests/checkups with my doc every 5-6 years and absolutely no side effects as of yet.

    I’m in pretty good health and look pretty healthy and young for my age. I’m not saying it’s good for you… but I’m saying if it caused damage I’d likely be showing signs at this point. I guarantee if I had been drinking this much regular soda I’d likely be quite a bit heavier.

  29. Isn’t caffeine the cause of the addiction and the withdrawal symptoms?

  30. Rich Butler says:

    Would non-sweetened Kool-aid mixed with Stevia be okay (because I don’t like drinking straight water)?

  31. Catherine says:

    I am one of the EX diet coke drinkers. I drank diet coke for many, many years. I regularly had muscle pains and aches, particularly in my legs at night. I was barely sleeping. I was miserable, exhausted and depressed until I decided to test a theory I had.

    I stopped drinking diet coke and immediately replaced it with carbonated water to appease my craving for the thirst quenching bubbles. I have not had a drop of diet coke in two weeks and have slept every night since then with NO problems. For me, this is a miracle! I have not slept this well in YEARS!

    I TRULY believe the diet coke was the cause of my problem and will never touch another drop.

  32. I am 5’7, 125 lbs. I drink diet soda every day and I don’t gain weight. I don’t feel bad, depressed or want more food. I exercise and try to eat healthy otherwise
