How to lose weight healthily within one month?

This is how I lost weight last year:

I used to be 50 Jin overweight, but now I'm only 30 Jin overweight.

I lost weight 1 month.

First of all, I gave up dinner (very important)

Second, halve the food intake (I can eat three boxes of instant white rice, and now I only eat half a box 1 box). It is enough to eat seven points full, and you still have to eat apples every night and after meals.

Thirdly, this summer vacation, I went climbing every morning and didn't go home until 1 1 at 8 am (I only climbed for two weeks and it rained for a few days).

After more than a month, I lost nearly 20 pounds.
