I have been on the Abs Diet for 8 days and have started to sweat for no reason. Has anyone else experienced this?

what are you eating?

it is summer.
but some sweating can be from a sudden drop in blood sugar.

I am following the Abs Diet 5 day menu. I just feel like my body is really screwed up. I am one of those that has to increase calories.

Then eat more.... you might be sweating b.c the body is having to work so hard to survive and do daily activities on some starvation diet.

Powder, like actors use over their make up. It helps to controls sweating and smudging/streaking.

a combination of 3 things

if you've drastically cut carbs for proteins, that will cause you to sweat a bit, as noted in CS42's post... you go into gluconeogenesis, which is an exothermic chemical conversion of Amino Acids (proteins) to glucose.

Couple that with a higher metabolism (I'm assuming your working out, and also increasing your meals from 3 to 6+), additional water in your diet, and the summer temps... you'll be noticably sweatier.

When I'm protien rich/carb poor in my diet, I'm sweating 1 hour after my 500 calorie, 50% protein breakfast.... winter or summer.

Ketosis (ultra low carb) weight loss is also exothermic. But your breath will stink of ketones as well....

I bring a clean Tee shirt to work in my workout bag to change into after working out, FWIW
