Before and after one month on Coca-cola

Before and after 1 month with Coca Cola

Before and after one month with Coca Cola

What happens if you drink 10 Cokes a day for a month? Everyone probably realizes that you’ll gain weight, but not everyone knows how much you can gain in just one month!

The Mirror: Man drinks TEN cans of Coke every day for a month – you’ll never guess how much weight he piles on

Nothing makes you fat as fast as soda.

On a more inspiring note, read how George from the experiment above next goes on a “zero-carb diet” to lose his soda pounds. It seems to be working well:

    Hard to tell if or how much he gained from the pics.

    The first is straight on, and does show a 'beer belly'.

    The second is at a different angle which makes his gut more pronounced.

    It's easy to game photos sucking in the gut with the diaphragm; I generally look at the ribs, which are not really clear here. The tale of the scale says it all, though. His description is ambiguous as to calories. It would have been more compelling if he stayed at the same calories before and during. Sam Feltham got a similar result eating excess calories on LCHF for 28 days (no weight gain and in fact reduction of waistline) compared to 28 days high carb caloric excess (significant weight gain).

    yes, he gained, but it seems to me he also stopped working out looking at his pecs. don't know, but i surely will not perform this experiment. bye

    Who the hell drinks 10 cans of soda a day??? A retard, that's who! This was a very unfair comparison, totally unreal. I drink a can (one) a day, I enjoy it tremendously and does me no harm. I can't believe such stupid article gets posted even. Ridiculous!

    This is a nice review. I apologize, again, for not being able to post pdf - for those who are interested just go to your local college library.

    Metabolism as a tool for understanding human brain evolution: Lipid energy metabolism as an example.
    Wang SP1, Yang H2, Wu JW1, Gauthier N1, Fukao T3, Mitchell GA4.
    Author information

    Genes and the environment both influence the metabolic processes that determine fitness. To illustrate the importance of metabolism for human brain evolution and health, we use the example of lipid energy metabolism, i.e. the use of fat (lipid) to produce energy and the advantages that this metabolic pathway provides for the brain during environmental energy shortage. We briefly describe some features of metabolism in ancestral organisms, which provided a molecular toolkit for later development. In modern humans, lipid energy metabolism is a regulated multi-organ pathway that links triglycerides in fat tissue to the mitochondria of many tissues including the brain. Three important control points are each suppressed by insulin. (1) Lipid reserves in adipose tissue are released by lipolysis during fasting and stress, producing fatty acids (FAs) which circulate in the blood and are taken up by cells. (2) FA oxidation. Mitochondrial entry is controlled by carnitine palmitoyl transferase 1 (CPT1). Inside the mitochondria, FAs undergo beta oxidation and energy production in the Krebs cycle and respiratory chain. (3) In liver mitochondria, the 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) pathway produces ketone bodies for the brain and other organs. Unlike most tissues, the brain does not capture and metabolize circulating FAs for energy production. However, the brain can use ketone bodies for energy. We discuss two examples of genetic metabolic traits that may be advantageous under most conditions but deleterious in others. (1) A CPT1A variant prevalent in Inuit people may allow increased FA oxidation under nonfasting conditions but also predispose to hypoglycemic episodes. (2) The thrifty genotype theory, which holds that energy expenditure is efficient so as to maximize energy stores, predicts that these adaptations may enhance survival in periods of famine but predispose to obesity in modern dietary environments.

    re: Who the hell drinks 10 cans of soda a day???

    Someone who wants to make a point that is presently only obvious to consensus nutrition skeptics?

    That aside, pop consumption is likely a bell curve distribution, and there are probably a lot of people who drink 10 cans (120 ounces, which is fewer total drinks in the common super-sized containers). I'll bet you don't have to get out much beyond 3-sigma to find that consumption rate.

    re: A retard, that's who!

    Nope. All it takes is someone trying to follow consensus nutrition guidelines, and failing, and not knowing why.

    re: This was a very unfair comparison, totally unreal.

    Yup. I suggest you commission a trial with better controls. I'm sure Big Sugar Pop, Inc. would be happy to fund it.

    re: I drink a can (one) a day,

    One can of Coke (in the US) is 39 grams of sugars, largely free glucose and free fructose (HFCS). 39 grams is 78% of an entire day's net carb limit on many LC diets, and 260% of the periodic (e.g. whole meal) limit. What's your blood glucose response? What is your liver doing with all that fructose distraction (besides raising HbA1c)? A typical consequence of routine glucose spikes is glycation.

    re: ... I enjoy it tremendously

    You can get the same sweetness, caffeine, acid and caramel color dose without the HFCS (or any simple sugar at all, or suspect artificial sweeteners). In the US, look at the Zevia product (which I found too sweet, so I ditched carbonated beverages altogether).

    re: ... and does me no harm.

    Many people, esp. younger people, think that, and they are mistaken. By the time they do notice a problem, it may be possible to arrest some (but not all) of the adverse effects, and even reverse some (but not all). For example, glycation of the lens of the eye might be arrested, but is not reversed. I know too many people in their 50s and 60s facing cataract surgery due to a lifetime of moderate to high glycemic diets.

    For a younger person today, they can expect to trip over blurred vision at age 55, assume it's covered by health insurance, but the reality of Universal Healthcare Rationing will have set in by then - they'll be put on a waiting list, asked to surrender their driving license, then told some years later that they're now too old to be worth the expense.

    re: Ridiculous!

    Dangerous. Although the point needed to be made, there can easily be long term permanent consequences to self-experiments like this.

    I used to drink sweetened fountain drinks and lots of em. I would get at least one refill of the 44oz cups at fast food places....right there is 5-6 cans of soda in one sitting so 10 cans in one day isn't so strange. I had the excess weight to show for it too. I stopped and found the weight was coming off slowly but surely. I would relapse when going on road trips and after just a weekend of it I could easily regain as much as 5-8 lbs so I knew there was a connection. I made it a point on my next road trip and subsequent ones to not drink anything sweetened and surprise suprise I would not gain weight. So now a sweetened fountain drink is only a sometimes thing for me and my weight has remained stable ever since.

    "fruit is not your friend" - what a load of crap! How can you compare an apple with a coke? The sugar in an apple comes with the right amount of fibre. No one got diabetes from eating an apple (or 10 apples for that matter!).

    "If you have diabetes type 2, this is very important to understand: Fruit is not your friend. "

    I agree with that. Crap is telling carb-intolerant people to eat lots of carbs.

    It all depends on the insulin response. Sometimes it is not proportional with carb content, just as meat consumption can result in significantly higher insulin response than expected. It is not about carbs, but rather insulin. They often go hand in hand though.

    Hi erdoke,
    one difference is we need protein, but we don't need sugars. You can't tell a diabetic to stop eating protein, but you should tell him to avoid carbs. Both create an insulin response, but only carbs are avoidable. Another difference is the glucose response: small with protein, big with carbs. Definitely not the same.

    "If you have diabetes type 2, this is very important to understand: Fruit is not your friend. ". I believe this thought is essentially correct.

    Hi Vicente,
    We are talking about type 2 DM. Your comments are more valid to type 1 diabetics and also to real burn-out type 2s. Type 2 is all about insulin while type 1 is more about blood glucose management.
    There are more insulinogenic proteins out there as well as less insulinogenic carbs. Some fruits definitely belong to this latter group. Also, some food combinations appear to give much lower insulin response than the sum of the components separately. This is important when creating a diet regimen for diabetics with the highest possible adherence rate.
    I saw really good results in reversing T2DM shared by e.g. Dr. Jason Fung with a less restrictive low carb diet and regular 3-4 days IF added. With this approach some fruits can still be your friends without a big boost in blood sugar. For sure it requires smarter design and a good understanding of insulin response to different meals.

    It IS true. I know 3 people, including my husband, who drank 5-8 (not 10) cokes a day and when they stopped, lost 15-20 lbs. within 6-9 months. That was the only change they made. Each can has 140 calories. It's done by drinking 3-6 at work, every time one is thirsty, instead of water, they go to the machine, then another 3-4 at home. There are those who drink 15 cups of coffee a day , although different in weight gain depending on what's in it.

    Only the fruits that don't raise significantly your blood glucose? I guess you like to argue.

    Hola Vicente,
    I'm still talking about insulin, not glucose. In case of type 2 high blood glucose is the result of the liver being insulin resistant, i.e. not (fully) stopping gluconeogenesis and not (fully) converting excess glucose to fat via de novo lipogenesis. Of course there is a good reason for that.
    You can find insulin raising capability of different food components and also some data on the difference of combining these. It's been long known that fiber, lactic acid, etc. can significantly reduce insulin response to foods.
    The most important thing to address in T2DM is to restore insulin sensitivity. For sure, over time very high blood glucose can have detrimental effects on various tissues, but after intervention most serious symptoms resolve in a matter of weeks.

    Love the site and your 2011 lecture on YouTube. I've also enjoyed your interviews with Gary Taubes, Peter Attia, and Jay Wortman, and the latter's documentary "My Big Fat Diet".

    I read the above article and followed the link to

    The trouble is, while he's obviously ballooned in size and cannot possibly be healthy, his triglyceride and LDL numbers are actually greatly improved, right?

    I wonder if Andreas Eenfeldt or any of the contributors to this blog can shed any light on this. It really undermines my confidence in using these numbers to monitor my health, and that of my father, who recently lost the vision in one eye following a retinal occlusion (similar to a stroke but affecting just the eye not the brain).

    I would like to see a similar experiment, but with orange juice in stead of coke. Just to rock the boat a little.
