Is it true that obese people must stay away from sweets?

Excess sugar in the body may be converted to fat to be stored. Therefore, obese people are advised to eat less sweet stuffs. Actually, not all sweeteners in sweet stuffs will cause obesity, so there is no need to “stay away” from sweets. For example, in order to meet the needs of obese people and diabetic patients, many sugar-free sweeteners have appeared and are available commercially. Nowadays, stevia is used as a sweetener in some foods and beverages. Stevia is sweet but it is not a form of sugar. It is extracted from the stevia plant, supplies us with energy and is 300 times as sweet as sucrose. Thus, people who are obese can feel safe in using. Xylitol is a five-carbon sugar. Both its appearance and its sweetness are like sugar and can be used as a substitute for sugar. There is also amino sugar with a high degree of sweetness but only minimal traces of calories. People who are obese can use all of these as sweeteners.

Sucrose, fructose and glucose are forms of sugar which are sweet. Obese people only have to avoid food rich in sucrose. This is because glucose is only mildly sweet and is commonly used only in treatments and not in food. Fructose is sweeter than sucrose, and the metabolism of fructose is less dependent on insulin compared to glucose. It can be directly absorbed by the small intestine and travel to the liver via blood. When a proper amount is consumed, the effect of fructose on blood sugar is lesser than sucrose and glucose. In addition, it does not lead to an increase blood lipid easily, seldom converts to fat for storage and therefore does not easily lead to obesity.
