You can stay away from eating at night, and I believe you can lose weight, because you consume less energy, but your consumption remains the same.
But if you start eating again at night, I think you will start to gain weight again.
In addition to keeping fit, exercise can also increase the energy you consume every day and increase the energy you consume. Even if you don't go on a diet, you can lose weight as long as you keep eating as before.
Therefore, the general effect of the two will be better and healthier.
At present, I personally eat cold dishes or porridge at night. I think you can start by eating less. You should eat less first, so that your body can adapt easily. I think step by step is better for your health.
When you do this, decide whether you need to eat at night. If you can't even eat less, what do you say?
