Caloric restriction leads to a type of survival mode called the anorexogenic cycle where everything you eat is stored in your fat cells, making you fatter.
Any weight loss is due to muscle atrophy and water loss.
If you are exercising regularly, you will have built muscle, thereby increasing weight.
Exercise has almost nothing to do with significant fat loss and dieting ALWAYS fails.
Feel screwed?? Well, you're screwing yourself, albeit unknowingly.
Ditch sugar and other sources of fructose like HFCS, honey, nectar, juice, molasses, maple syrup and white flour products (most breads, crackers and pastas) for a month and see what happens to your acne.
Oh, wait, wrong answer...or not.
Acne is caused by the same thing as obesity, diabetes II and most heart disease.
This isn't opinion but truth that won't change if you disagree, which your addicted brain is trying to convince you that I am full of crap.
I may be at times, but this is independent of you and me;)
