Eat a boiled egg instead of yolk in the morning, a cucumber at noon and nothing at night. Is this the way to lose weight?

That must be insufficient nutrition. Eating like this can reduce weight and be more balanced.

Morning: sugar-free soybean milk 1 cup+1 boiled egg+1 vegetable bag.

Brunch room: 1 fruit+1 cup of low-fat yogurt.

Afternoon: half a bowl of rice +2 portions of vegetables+steamed fish (or low-fat chicken and shrimp)+1 portion of laver soup.

PS: If vegetarians can change meat into bean products or eat them instead.

Lunch and dinner: 1 cup of herbal tea +2 soda cakes.

Night: 1 night coarse grain porridge+cold kelp silk

Eat a tomato or cucumber when you are hungry at night and drink a glass of low-fat milk before going to bed.

PS: There are also corn porridge and cereal porridge, all of which are good slimming porridge. Cucumber and shredded radish salad is quite good.
