You don't need to exercise. It's what you eat and how many times a day. I don't exercise, all I do is eat 2 or 3 meals a day (no snacking) and fast at night and I've lost weight without trying. If you eat healthy fat, no sugar or wheat the weight will fall off. Only if you eat when you are actually hungery. Not emotional hunger. There's a podcast all about this by a doctor if you are interested I will link it to you.
