There are many ways to lose weight, but the key is only one point: "reduce calorie intake and increase calorie output." After you start to lose weight, you should do it on the premise of ensuring nutrition. Plenty of exercise and sweating are the minimum standards, followed by eating foods rich in carbohydrates. Because you will want to eat after a lot of exercise, if you overeat, your previous efforts will be in vain. Mind you, it's no use just running. You need to supplement nutrition to lose weight.
