Isn't it easy to gain weight by eating "zero fat" food? Why?

Many people have a misunderstanding that people gain weight because they eat too much body fat. Actually, it is not. Eating too much body fat will naturally make you fat, but people who don't eat body fat will also be fat. This is because the factors of weight gain are: total calorie intake exceeds total calorie consumption. Therefore, if you want to be thin, you need to be constant-intake is lower than consumption. With the increasing awareness of scientific diet, many food manufacturers have put up the slogan of "zero fat" in order to better attract customers who pursue perfect diet and health.

This makes many people who are worried about getting fat willing to pay, but are those so-called "zero-fat foods" really not easy to get fat? In fact, zero fat is not equal to zero calorific value! The ingredients usually contain nutrients including sugar and carbohydrates, lipids, protein, minerals, vitamins and water. Among them, sugar and carbohydrate, human fat and protein can all generate kinetic energy through air oxidation in the body, so these three are called productivity nutrients. Zero fat only means that the fat rate is zero, but if there is sugar, carbohydrates and added sugar, it is just as powerful.

In addition, the direct cause of obesity is that kinetic energy intake is higher than kinetic energy consumption, resulting in kinetic energy overcapacity. Compared with sugar, carbohydrate and protein, food containing human fat tastes better, which is very easy to arouse appetite and make people absorb a lot of kinetic energy. Therefore, many people mistakenly believe that human fat is the only factor leading to obesity. However, I didn't know that sugar, carbohydrate, protein and body fat are the three major energy-supplying substances of the body. No matter which one is ingested too much, the absorbed kinetic energy will exceed the kinetic energy lost by the body.

Cause excess kinetic energy and make people gain weight. Therefore, zero-fat food is not necessarily fat, and we need to pay attention to manipulating the supply of zero-fat food! It is not difficult to see that people don't have to be superstitious about all kinds of foods that claim to be "zero fat". Why not look at the ingredient list and nutrition reference value for a long time before eating, and see if all kinds of sugar are added, and they rank high, and what are the calorific value and sugar content respectively.
