If you want to lose weight temporarily, you really don’t have to exercise; just eat less food (think about people in hospital who lose weight without exercising). However, if you have already lost quite a bit of weight and you want to maintain and not ‘regain’, then you will need to be active! It’s all a matter of balance, as there is under-eating and over-exercising…nobody said it would be easy, but it’s OH SO WORTH IT! Keep in mind the importance of strength training as this helps to maintain muscle mass; while high intensity interval training can lead to fat loss, particularly abdominal fat.
Don’t WAIT to manage your WEIGHT!
