The shops have entire sections for diabetics, where fructose products are presented in a large assortment. There is marmalade, chocolate, waffles, fructose candies. Often those who want to lose weight fall into these sections. They hope that if fructose appears in the diet instead of sugar, the numbers on the scales will tremble and go down. But is it?
We will answer right away - fructose is not a panacea in the struggle for a good figure. Rather, it will even hurt. And there are reasons for this, first of all, these are the characteristics of the exchange of this compound.
Fructose does not significantly increase insulin production. Of course, this is a positive property, because it is the background in which insulin is increased that makes the body put off fats. But in the liver, our fructose will be converted to glycerol alcohol, which is the basis for the synthesis of fats in the human body. If we ate only fructose, perhaps a big problem would not have arisen, but those who lose weight do not switch to fruits or juices in most cases. And insulin is produced not only as a reaction to sugar, but also to proteins (you cannot refuse proteins!). You ate meat and then ate fruit - and the body went into accumulation mode, and if the calorie content is reduced, as is often the case with losing weight, he will try to postpone a maximum of fat, which is perfectly synthesized in the glycerol formed in the liver. So fructose instead of sugar in a biochemical respect is an unprofitable solution.
In addition, do not forget that the calorie content of fructose is the same as that of glucose. Therefore, saving calories on it will not succeed. Of course, fructose in diabetes is a good alternative to sugar because it gives energy and tastes sweeter. But so many diabetics can not imagine a full life without sweets. Fructose sweets are inexpensive, and there are not enough products on other substitutes in our stores. In addition, the consumption of fructose by diabetics allows us not to provoke the insulin system once again, which, of course, is a very significant argument in favor of fructose.
Another problem with the consumption of this substance is that it is not absorbed by the brain. The brain asks for glucose, and when it ceases, many begin to experience headaches, aggravated by physical exertion. Fructose instead of sugar will not give the brain the desired level of nutrient in the blood, which will immediately affect health. In an attempt to synthesize glucose, the body will begin to destroy muscle tissue. And this is a direct path to obesity in the future, because it is the muscles that consume a lot of energy. So it’s better not to provoke your body. Of course, with diabetes , there are not so many alternatives for patients, and fructose is often chosen. The benefits and harms of this substance for diabetics have been studied for a long time. And with diabetes, the use of this compound is advisable, for weight loss - no.
Also fructose does not cause a feeling of fullness. Probably, many of the readers know that after eating an apple on an empty stomach, you want to eat more. Only mechanical filling of the stomach with other apples helps to overcome hunger, but not for long. Biochemically, hunger remains. And the matter is not only in the low calorie content of apples, the fact is that leptin, a substance that promotes a feeling of fullness, is not properly produced.
Fructose instead of sugar - is this a reasonable preference? As we can see from the above, this is not a very reasonable choice. Of course, this does not mean that you need to give up fruits and freshly squeezed juices, but to pour fructose into tea instead of banal sugar is not worth it. Indeed, in many, a large amount of this substance can cause indigestion. Not everyone is able to absorb fructose without problems. So if you are not a diabetic, but just want to reduce weight, it is better to turn to other sugar substitutes.
