Diet control means eating less greasy and spicy food and increasing vegetables, fruits and staple food, and protein can't be less.
Exercise for an hour every day. You can choose your favorite and convenient way. Running, badminton and aerobics are all acceptable. It may be difficult at first, but you will like sports step by step.
If these can't be done, you can only use slimming products, such as some meal replacement powder and enzymes.
