Famous trainer John Romaniello disagrees strongly...in fact he believes you can lose in excess of 13 lbs of fat in a week by controlling hormones, using intermittent fasting to your advantage following a leptin resetting cheat day, and doing high calorie burning workouts in a specific order that help manipulate these hormones.Jitterbug said:To lose 5lb of fat in a week (week one or not), you're looking at a deficit of 2500 calories a day. Good luck achieving that with limiting sugar and walking (which burns practically nothing).
