Weight loss is weight loss? Wrong! Weight loss belongs to the behavioral approach aimed at reducing excessive body fat and weight. Weight is a parameter to measure a person’s fat and thinness, but it is not the only criterion. In addition, waist circumference is also a key data. Specifically, in China, a waist circumference of ≥85cm for men and ≥80cm for women can already be considered centrally obese. Even if the weight is not obvious, it is still the ranks of obesity and should lose weight. The elevation of weight is not only more fat, but also more water, and possibly other reasons. Dehydration alone will also reduce weight, but that is not weight loss. If you don’t believe me, you go to a sauna and steam, weight loss is especially fast, provided you don’t drink water. So what is the real meaning of weight loss? Weight loss is fat loss. The standard seen by the naked eye is “waistline reduction”. Increased waist circumference indicates obesity, and everyone knows that obesity is the “advance guard” of high blood pressure and diabetes. Obesity can lead to high blood pressure, diabetes, heart disease, cancer, cholecystitis, arthritis and a series of diseases. As early as 1996, the International Obesity Task Force pointed out: obesity will become the greatest enemy of human health and life satisfaction in the 21st century. The World Cancer Research Foundation reported that for every 1 inch increase in waist circumference, the risk of cancer increases 8 times. The World Heart Federation predicts that obesity has the potential to replace smoking as the leading killer of heart disease and stroke. Now, we understand that the biggest enemy of weight loss is fat. So, how do we eliminate the excess fat in our bodies? Simply put, “keep your mouth shut and your legs open”.
