You cant exercise away a bad diet and too many carbs. You can eat 500 calories incredibly fast compared to how much exercise you need.
Just don’t eat. One meal a day or OMAD. It isn’t that hard. Anytime I find myself getting a little chunky I do this and it works. Your body doesn’t need to eat 3 times per day. I always fast until 12 pm.
If you really want to lose weight fast for a full 36 or 48 hours. It has been shown to have many beneficial effects when you go into ketosis.
