1. Perseverance
2. Quit any drinks.
You don't need to do much exercise, just walk. I walk 4-6 kilometers every day.
4. Eat less and eat more. I feel a little unable to eat any more meat. Eat more vegetables if you think you can.
5. Drink more hot water.
I lost 5kg in the first month, so slow down in the back. You know, the scientific method will not be too fast.
