After watching your diet all day, you seem to have eaten nothing but staple food and fruit. Your unbalanced nutrition intake is not only bad for losing weight, but also harmful to your health.
Not only do you lack vegetables, but you also lack many things, such as calcium and protein. You can add some milk, lean meat, soybean milk, eggs and so on.
Let's start with breakfast It doesn't matter. You can also replace black sesame paste with milk porridge, which not only supplements calcium but also helps to detoxify the intestines. But you should eat some mixed vegetables or something to supplement your vitamins.
It's not good to have lunch like this. You'd better eat some vegetables, lean meat, vitamins and protein.
You can eat a small amount of staple food for dinner and list the dishes.
In fact, the most important thing to lose weight is to eat vegetables, because the calories are extremely low, and you can still eat enough or not. You can arrange fruit between meals. When you are hungry, two fruits a day are enough, because they are sweet and you can't eat more.
You 18 years old, losing weight blindly will affect your physical development and you can't concentrate on your studies.
If you eat too few calories and don't exercise, it will reduce your basal metabolic rate. If your basal metabolic rate is low, the direct consequence is that you will not only eat less, but also gain weight.
I suggest you eat reasonably and scientifically, increase exercise and lose weight step by step.
I am a nutritionist, I wish you success in losing weight!
