I once tried the apple diet for three days, and those three days were really hard, but I persisted and lost 6 pounds.
On the fourth day, I ate normally and came back!
Later, I chose to lose weight healthily, and I only consumed the following things during my weight loss:
Rice, kelp, fish, lean pork, vegetables (green leafy vegetables, broccoli),
Apple, pure milk, boiled water,
Don't eat anything else (occasionally break the precepts, hehe)
I have lost weight for more than 2 months 10 kg, and I don't exercise (I don't like sports).
It used to be 1 10, but now it is 100, and its height is 168cm.
