It is feasible. Honestly, how long can you last? And high-intensity weight loss is easy to rebound, so I suggest not to ask too much. First, you must go on a diet. But it doesn't mean not to eat. You must eat eggs and drink milk in the morning to be nutritious. It doesn't matter as usual at noon, but eat less high-calorie food. If you like meat, try eating fish. You must avoid eating at night. You can eat vegetables or fruits in the evening, but you must eat them before and after 7 o'clock. Fat tends to accumulate. Drink less water at night to avoid edema. Summer is coming. Watermelon is a high-sugar fruit. Eat less and eat less ice cream. In this way, swim for 2 hours every day. You can lose about 10~ 15 kg in a month. This is personal experience, I hope it will help you!
