First of all, I think I don't know if you are really fat. From 168 to 104, you shouldn't be fat. I weigh153,90 kg, and I am thin (really thin, unconsciously), and my sister158,98. So say the method. I have been a fat man for the past 20 years, but I am 153 kg. I lost weight at the end of the year before last. The trick is definitely not to eat snacks or drinks, but to drink a lot of boiled water for 2L every day, and then I can eat more (I eat without restraint). Drink Pu 'er tea for two months (it is cheap to lose weight, especially tea). Later, I can jump to 1000 times at a time. Average ten minutes 1000 times. It is best to burn calories 45 minutes before I start to lose weight. This is all my methods. What I want to say is that the most important way to lose weight is never to eat snacks, sweets or drinks. This is obvious. I lost weight in three months, to 95 and then to 88, but now. ! ! So is my sister. I eat a lot of food and fruit. Believe me, a person who has been fat for 20 years has lost weight. But my face can't help it. Because I am a chubby baby with a round face, I have lost weight 10 kg, and my face is still the same. The bone problem was a bit difficult at first. As long as I really stick to it for a week, it won't be so bad.
