How much exercise you eat takes at least two or three times as long, and eating too much diet food will make you fat. You must keep exercising. Loss of 30 in 300 days, loss 10 days. That's more like it. 10000 calories equals 1kg fat. For example, the calorie of banana is 93 calories, if you eat 10 calories, it is 930 calories, and the calorie of rice is 1 16 calories. Three meals are 348 calories. If you eat a bowl of rice, you should exercise 1 hour for more than 30 minutes. If you eat three meals, you should exercise for 4 hours and 30 minutes. This is not a blow.
