If you are determined to lose weight, don't eat dinner directly, just make sure that you don't eat dinner, and you have almost the same lunch, which will definitely be effective within 1 week.
2. Exercise more, but don't be violent. Hula hoop, table tennis, skipping rope and swimming are all ok.
3. You can buy a weighing scale, see the changes every day, and remind yourself of your determination to lose weight at any time.
When diet and exercise are combined, the slimming effect is obvious.
I hope you can accept my answer as the most satisfactory answer, because I am very attentive.
To tell the truth, you are not fat.
