You can exercise every morning, such as running and skipping rope. Personally, I think swimming is better and I can lose weight in a month. Be sure to have three meals a day. Dieting is useless. Eat less salt. Drink two cups of hot water after getting up every morning. Don't wait for breakfast. Before that, drinking some honey water is also good for detoxification and beauty. It's good. Be sure to persist.
This is my personal experience, and it was very successful. I lost a lot of weight.
You can have a try.
