Of course not. My dad used to have high blood lipid and cholesterol, and he weighed 90 kilograms. He swam for more than a month and lost 6 kilograms. He usually pays more attention to his diet (don't diet, eat less high-calorie food, and it is best to drink less to lose weight). He went to the hospital for examination, and his blood lipid and cholesterol were not high. But he travels a lot, sometimes for a month, and his weight is still very good, and he has not rebounded. However, although he can't swim when he is on a business trip, he still insists on exercising every day and trying to control his diet.

So losing weight depends on persistence. If you swim, you don't need to swim for a long time. My dad only swims for 40 minutes at most, and it's still very slow. The most important thing is to keep it. When you can't swim, you can't just relax. Running and walking can also have good results. That's my dad.

Real case. Oh!
