Losing weight without medication and losing weight naturally is the best recommendation for girls. You should ensure that the lunch breakfast is nutritious and eat less meat and eggs. Remember that you can eat less vegetables and fruits or skip dinner at most a day, but you must ensure a good breakfast.
During exercise, you can also do sit-ups or lie down and touch your left leg with your right elbow, and vice versa.
Stick to one direction and rub your stomach for more than half an hour every day.
Legs: You can lie on the bed and lift your legs to wait for the bus.
