You don't need to swim every day to lose weight. Keep swimming frequency 3-4 times a week, and the swimming time 1 hour is the most beneficial to lose weight.

Swimming can lose weight, because the resistance of water when swimming is much greater than that of air when moving on land. Walking in the water is laborious, and swimming will definitely consume more calories. At the same time, the thermal conductivity of water is 24 times higher than that of air, and the water temperature is generally lower than that of air, which is also beneficial to heat dissipation and consumption. So swimming consumes much more energy than running and other land projects, so the effect of losing weight is more obvious.
