Don't lose weight for the last two to three months. Just after surgery, I still focus on fitness. It's not bad to get back to normal and lose weight. Weight loss or exercise and diet control are reliable. Diet tea is effective when others drink it, but it may not be effective when you drink it. Go running, play ball when you are free, and walk more after dinner. Eat less and eat more meals, 7 or 8 points at a time. You can drink some lotus leaf tea, balsam pear tea, Pu 'er tea, rose tea, black tea and green tea. A cup of sugar-free black coffee after a meal is better, but you should exercise more. You can't really lose weight by drinking tea anyway. Just drinking tea can clean the stomach and eliminate toxins.
