Some people can lose more than 2 pounds in a week with a dedicated fitness program and serious dietary restrictions.The time and effort required to lose weight that quickly is grueling and usually unsustainable, though. Even if you can lose a notable amount of weight in a week, a lot of it will be water weight — not true belly fat. Weight you lose quickly is likely to be regained quickly too.
Exercise to Lose Belly Fat
Belly fat is usually the first weight lost when you start an exercise program, explains Rush University Medical Center. If you are new to exercise or coming back from a long hiatus, you can’t expect to hit the gym for hours at a time to burn off fat that first week. This only increases your risk of injury and burn out.
