I am a 26-year-old male, weighing 155 kg and height 173 cm. I have a big belly and want to lose weight. Does it matter if you keep exercising and jogging for an hour at 5 o'clock every morning? Science? Of course it works! Recommend my method: you must have breakfast. Halve lunch and dinner, do not eat fried and baked food, do not eat sweets, and prohibit all snacks. You can't eat anything after 20 o'clock (except boiled water). Run in the morning 1 hour, jump rope 300 times at noon, and walk after dinner 1 hour. Running can be done on a treadmill. It's not that hard. It's all jogging, walking, relaxing aerobic exercise, and eating something before running, such as a steamed stuffed bun. Another problem that needs attention is that you can't sleep late. Seven hours is enough.
