The effects of 1L of Coke a day for 1 month.

[Phedder]

A few months back I took part in a study that had me drink 1L of coke per day for a month, and I thought I'd share the results.

They took baseline readings and then again at the end of the study. I didn't make many conscious changes in my diet throughout (perhaps slightly less sugar from other sources) and I even tried to turn the 1L to my advantage as much as possible by partitioning it around training. I had one 600ml bottle and one 355ml can for each day, but on training days I had 1 can pre-workout, drank the 600ml+bcaas during training, and then another 355ml can with my post-workout meal. On rest days I had one 600ml bottle. Here are the results:

Ignore the bodyfat %, that was taken via bio-impedance. Calipers had me reading much lower, though I'm sure there would have been an increase. I find it interesting that my fasting glucose levels actually dropped for the follow up reading, not sure why that would have happened. But aside from that, basically every measure got worse. None put me outside the acceptable range.

The bad, in relative terms;

Total Cholesterol increased 11.8%

LDL Cholesterol increased 13.4%

Total Cholesterol/HDL ratio increased 9.2%

Triglycerides increased 39.4% :shock:

Plasma uric acid increased 10.5% (which put me at the high end of acceptable)

What I've learned from this, excessive continual consumption of sugar soft drinks is bad. Mind blowing, I know :pfft:

The purpose of the study was actually to compare the same level of sugar intake from soft drinks to fruit. The full results haven't been released yet, and I'll be very interested to see if where the sugar was coming from had much of a difference. I'll update you guys when it's released.

Thanks Phedder. Very interesting. Looking forward to the rest of the results.

The fact you consumed the coke around trainings and the fact you are fit and healthy and train regulalry probably limited the effects a lot more as well.

[Chemo]

Wow. and these are results from a strength athlete trying to minimise damage by timing the intake too?

Imagine what this would do to your average Joe. Diabeetus gains.

I would love to see the same thing for diet drinks too. I bet they have some nasty effects somwhere down the line.

Cheers Phed.

will be interesting to see it in comparison to fruits, wonder if the study also will make any links to that case where the nz woman died from excessive consumption?

just thought ill post as a commonsense reminder in case anyone gets excited and decides to use it on a bulk..

- 7~10L of coke per day

- 30 cigarettes per day

- Mother of 8

Wonder if that woman knew that she was on the worst diet one could be on

Cool study, Phedder. The full results will be interesting. Were the other participants mostly athletes too? If so, they could find that the sucrose from Coke gets used as energy, whereas the fructose in fruit doesn't - so the fruit-eaters might actually get fatter. Fascinating!

You didn't feel like drinking 10L instead of 1L, and smoking a modest 30 ciggies a day?

I thought fructose was stored in the liver and utilized when needed by the body.

was this 1L of coke over and above your maintenance cals? None of the increases seem to bad and definitely explainable by your weight gain and while LDL increased, your HDL did slightly too.

They weren't meant to be. They actually wanted participants who were 'pre-diabetic' but the only defining measure you needed to be included in the study was a BMI of 28 or higher :pfft: Given that they were offering $100 for the study, and either a lot of free coke, or free fruit (which I was hoping I'd get) there ended up being a few other lifters or rugby players put there names down. They then added an exercise questionnaire to help deal with any biases that came through, but I imagine many of the other participants were more sedentary.

Nope, I like having teeth

":36ci0253]are those increases actually significant though? i mean in terms of negative health effects. just looking at the numbers it doesnt look like much of an increase

I did previously eat a fair bit of chocolate after trainings, and cut right down on that throughout the study. But I'd have estimated that to be around 30-40g of sugar on training, no where near the 145g from coke I was having on training days. So yeah, a fair bit above maintenance there The only two that really concerned me were the increases to triglycerides and uric acid. Although my triglycerides were still well below the 1.7mmol/L they quoted for greater risks, the uric acid increase put me right at the top of the acceptable range.

I was slowly bulking through the entire year before starting the study as well, so it's not like I had been sitting at maintenace calories around 102kg for months on end, and then this shot me up to 104kg. It certainly helped, but I really wonder how different the results would be if I had have gained those 2kg without coke, and more whole foods consumed for the calories instead.

wow cool study!

even ignoring the bodyfat testing...gaining 1.9kg and 1.9%b.f on a 102kg body is freakily similar and almost a decent correlation.... your body didn't need the excess sugar so it did what all our bodies do, converts it and stores it away as fat

1.9kg bw gain, 1.9% bf gain :shock:

still shocked 1/4 (23%) of your body is fat tho \:D/ that's funny

[Phedder]

As I said, the bodyfat was taken via bio-impedance. Those metal plates you stand on that will change the results if you go and take a piss

In October (so in the middle of the study) I got my bodyfat measured by calipers at 15.3% at 103.9kg. I'm sure I did gain bf during the study period, but how much I can't be sure. I wouldn't say it was exactly 1.9% because the variation with those plates is insane, it could have been anywhere between 0.5% to 3%

[Android]

oh good, I always thought this was you that's why I was surprised....

[Phedder]

Not since I was about 75kg :pfft:

[M.T]

Wow that's intense man thanks for sharing those stats. Should have seen a dentist before and after too bet those things are headed for root canals or somthing.
