It's certain that you can lose weight by eating so little, but it's just hard to stick to it. Especially if you used to be a hungry person. I suggest eating cereal paste food in the morning, which is good for the digestive system, can make you full, ensure you work and study in the morning, and eat well at noon, especially rice and vegetables. Don't eat fried and high-fat calories and sugar foods. Eat fruit or tofu at night, but be sure to have a small bowl of rice when eating tofu. The most important thing is to strengthen exercise. Walking is a very good and easy way to stick to.
Ps: Always be with friends in good shape! !
