I remember reading in JMB’s article that caffine is bad for insulin sensitivity, my question is is there enough caffine in diet sodas to have a negative effect or am I ok drinking diet soda w/ a carb meal? Thanks!
Anyone?
The low-carb Dr. Atkin’s diet says no caffiene for that reason. I’ve lost weight on it drinking caffinated coffee, so I guess it depends on the individual. The book really doesn’t go into it if I remember correctly. I read about it in a Dr. Atkin’s question and answer section on his website.
Can someone help me?
Of course you’re okay.
I can’t figure out how much caffeine’s in it. But I’d imagine that any would be less than great, besides those are very high-glycemic carbs in there.
diet soda doesnt have carbs it is calorie free
I’ve never had a problem in my cutting cycles when using caffeine, whether it was diet drinks or MD-6.

There is about 50-70 milligrams of caffeine in an average soda. A regular 8 oz cuppa coffee from Starbucks is around 200mgs. But when was the last time Starbucks soldjust an 8oz cup? The smallest size is 12 oz I think.
The real problem with diet soda is the artificial sweeteners. They actually make you crave sweets/simple carbs, just as much as rgular ol sugar does. Plus, the artificial sweeteners and other chemicals are really just poison. Not the best choice for a “healthy” T-man.
- First of all, there is no reason for aspartame to be bad for. It’s actually a di-peptide of aspartatic acid and phenylalanine. The molecule actually has an “L” shape like sugar, but it fits in the taste bud receptor for sweetness upto 200 times better than sugar. Actually I did the math and that adds upto to 1/50th a gram of protein for 10 oz. soda. So the notion that aspartame is bad for you really only applies to those with PKU.
- My experience with caffeine is too avoid like the plague while bulking and to use liberally when cutting. I am sure it decreases insulin sensitivity, but in doing so helps to liberate fatty acids into the bloodstream for use as energy. If you are concerned with loss of insulin sensitivity while using caffeine, supplement with at least 200 mg. ALA.
Reege, one of the main reasons I like diet soda is it kinda settles my sweet tooth I dont find it makes me crave more.
Beandog, Why do you avoid caffine like the plaugue on a bulking cycle? Thanks
=w=, I can relate to your love of Diet Soda. I’m a Diet Coke addict, myself 
Currently I’m on a keto diet, and am consuming as much of the stuff as I usually would. It has not interfered with ketosis, or my fat loss, to any noticable extent.
People respond to caffine in different ways. Do what works for you, in this instance.
Beannog’s right. Aspartame is made up of phenylalanine, aspartic acid, and methanol (phenylalanine makes up 50% of the total mass). Those people with phenylketonuria (PKU) cannot metabolize phenylalanine properly, so they are the ones who have a problem with aspartame and other products that contain phenylalanine. This is why you see “Phenylketonurics: contains phenylalanine” on the sides of diet sodas, etc… This is a pretty rare condition though, I think it’s 1 in 10,000-15,000. Aspartame is pretty much safe. Besides, if phenylalanine were a concern, do you think they’d put 3g of it in a serving of Surge? Now it may increase carb/sugar cravings simply because you taste it and say, “Hey, this is sweet, sweet stuff is good, I want more sweet stuff”, but this is mostly psychological, not physical.
As far as the original question goes, yes, caffein is bad for insulin sensitivity, but I believe that the condition is chronic (meaning that insulin sensitivity is lowered temporarily). So you can probably get away with having caffein as long as you wait a little while before having carbs. In other words, don't eat a doughnut with your coffee.
