How can I lose weight healthily? What is the most effective product to lose weight?

I recommend you to drink Pu 'er tea. Pu 'er tea has the effect of reducing fat and diuresis, and the biggest benefit is nourishing the stomach. In fact, the healthiest way is to eat less and exercise more, but eating less will cause gastrointestinal discomfort, so Pu 'er tea can help you nourish your stomach and reduce fat, so that your food intake basically needs no deliberate control, which is healthy and effective. Just try it.
