Eating too much sugar and fat is the main reason for your rapid weight gain. If you want to lose 10 kg in a month, you need to give up all sweets and sweet drinks, all visible fat, and refuse to stir-fry with big oil.
This may lead to you not eating enough, so be sure to eat more vegetables with high plant fiber, which can increase your satiety.
In a word, in this month, you need to strictly control your diet and increase your body consumption. Thin 10kg is a definite goal. Finally, if you are a male, losing 10 kg should have little impact on overall health.
If you are a female and lose 10 kg a month, it may have a certain impact on your physiology. Of course, this is beyond the discussion of this issue, just hoping to attract everyone's attention.
