Is this diet harmful to health?

(early) morning

A cup of boiled water

A loaf of bread and a cup of soybean milk.

Exercise for 20 minutes to lose weight

Eat only rice and vegetables at noon and evening.

Eat only eight full lunches,

No afternoon tea,

Drink water when you are hungry.

Dinner is full at seven o'clock,

Don't eat snacks, fish and meat every day.

Today is a holiday,

Don't worry about no spiritual practice.

Problem supplement: Eat two kinds of fruits regularly every day, and don't eat at night.

It's very similar to my diet, except that my lunch ensures protein's intake. Otherwise, you will feel sleepy and uncomfortable all day. If you lose weight according to the recipe in the question, your face will turn yellow. Body is there, health is gone, and the two are weighed. Advise my sister to think twice.
