The cold more effective than the hot or exercise to lose weight

Cooling is therefore much more effective than sweating for weight loss. The mechanism is explained by the fact that when the general temperature of the body is lowered by the cold, the thermogenesis is triggered, accelerating the combustion of the glycogen in the cells. If the muscular and hepatic glycogen is depleted, the body then withdraws from the fat reserves.

60% of the energy is spent to stabilize body temperature.

For blood subjects who rapidly become overweight, the cold is much more effective to lose weight than exercise. In the daily energy budget, 60% of the energy is needed to stabilize body temperature at 37 ° C, while 12% is used for the work of organs such as liver, kidneys, lungs, digestive system , The heart, etc …, the rest, only 28%, assures the needs of physical activity.

We thus find that cooling the body is much more effective in increasing the oxidation-reduction phenomena than doing exercise. The basal metabolism can be multiplied by 6 in cold water, whereas it can only double in physical effort. For example, running 2 kilometers in 10 minutes, or walking 45 minutes, burns about 120 kilocalories while the same amount is lost in 5 minutes bath at 24 ° C.
