Stop it.
Just stop.
There is nothing detrimental about a safe program that combine aerobic and anaerobic training with a diet low in sugar, high in fiber, and with a portion of calories. While the % of BF you will lose when you begin to train and eat less will go down due to your metabolism slowing, this is a good thing due to it coming to a more normal rate. Besides, weight loss is a marathon not a sprint.
Fuck me, working out depletes your glycogen so that way the sugar in your blood has somewhere to go assisting with insulin resistance. It helps lower resting heart rate, increases VO2 max, lowers blood pressure.... fucking hell, all issues that obese people suffer. Thin inactive people suffer it as well, but they don't have those issues coupled with a high waist to hip ratio.
@Waffle, this dude, right here, is.
