all know the benefits of weight loss, especially if it is to fall waist circumference, that's when it exceeds 88 cm (women) or 102 cm (men) is associated to a greater propensity to develop the consequences of obesity (increased likelihood of developing diabetes, cardiovascular disease, but also some types of cancer). Weight loss induces beneficial effects in fact, proportional to weight loss, such as reduced plasma lipids (cholesterol and triglycerides), while it raises the weight gain values. In particular, a weight reduction of at least 5% and maintained over time, allows a substantial reduction in triglycerides, while having a significant reduction in LDL (so-called "bad" cholesterol) to normal, we need a weight loss of at least 10%. Weight loss also allows a reduction of both systolic and diastolic pressure, in proportion to the pounds lost. If the weight rises again, the pressure rises accordingly.
Some interesting information about weight loss: about 75% by weight that is lost through diet is made up of fat mass, while the remaining 25% is made up of muscle, and lean body mass. If, in addition to diet-induced weight loss is through exercise, the percentage of lean body mass that is lost can ò be halved. Most (if not all) of the fat that is lost comes from a decrease in the size (triglyceride content) of fat cells, not by a reduction in their number. The distribution of the fat that is lost is heterogeneous, with a relative majority of the loss in intra-abdominal than other areas of the body, especially in those where it is already accumulation at this level. The diet also induces a reduction of fat content in myocytes (muscle cells) and liver.
