First, you must pay attention to your diet. Never eat high-calorie and high-fat food. You must eat three meals less. Two bowls of porridge are better than one bowl of dry rice. It's best not to eat meat or anything. Whether fat or thin, of course, you can eat fish properly. You should eat some vegetables. That's basically it.
What kind of exercise should I do? Of course, aerobic exercise, push-ups and squats will never make you slim down, but will only make you strong. What kind of aerobic exercise? It's hard to say whether you like it or not, such as jogging in place (the slow kind) and dancing in radio gymnastics if you insist. The key point is time. If you want speed, do it once in the morning and again in the afternoon or evening. The duration of each time must be more than half an hour. Do it for ten days and a half months, preferably for an hour. Then there is no need to delay for a long time. Just do it every day.
You sweat a lot every day, so drink more water. Drinking more water also helps to lose weight. You are very tired. You may be so tired that it hurts to walk.
