Saturated fat would lead to increased appetite and weight gain

Do you find it difficult to control your appetite? Can not you stop eating when you sit down to eat? This remains a common problem that some of us explained by a "lack of will." Also see our articles "Reduce appetite, tips for controlling appetite" and "7 tips to strengthen the will and lose weight more easily. Now a new study shows that the tendency to over-consumption could be partly explained by the saturated fat found in foods, especially meat and dairy products. A disadvantage of foods high in fat, especially those rich in saturated fat, may be their ability to increase appetite and block the signal that tells the brain that the body has consumed enough food. Also see our articles "Tips to avoid over-consumption due to stress or emotions" and "Grease and fat cells: 7 Things to Know".What is saturated fat scientifically speaking?

Saturated fat is also known scientifically saturated fatty acid (see definition of "fatty acid" here). It is a fatty acid that has carbon atoms completely saturated with hydrogen. Each carbon has the maximum possible hydrogen. The molecule is saturated, we can not add more hydrogen.

Saturated fats tend to be solid at room temperature (the room for example). The agri-food industry have increased the intake of saturated fats by hydrogenation total unsaturated fat. Their technique provides industrial saturated fatty acids, and some industrial trans fatty acids (trans fat). Also see our article "What foods have the most trans fat?".

What foods do you find they are generally saturated fats?

Saturated fats are found among others in animal fats (milk, cheese, butter, meat, bacon ...), in coconut oil and palm oil. Does saturated fat increases the appetite and is gaining weight?

According to this new study, published in the journal "The Journal of Clinical Investigation", saturated fat increases the appetite by making the body believe it is still hungry after a meal. Also see our article "Controlling Hunger: 5 effective methods to control hunger.

Researchers have found that some saturated fats, especially palmitic acid, activates a gene called gene PKCB. PKCB When the gene is activated, it makes the body resistant to hormones, leptin and insulin, which signal the body it has eaten enough. Also see our article "Delete and manage appetite and hunger with 12 foods. Leptin play an important role in controlling appetite and satiety regulation. One theory is that obesity is caused by leptin resistance, when the body no longer responds to the effects of leptin signal telling him to stop eating. Studies have shown that obese people have high levels of leptin circulating in blood, but appear to be insensitive to leptin that despite its abundance. Also see our article "Losing weight in the long term: a question of will?".

The effects of foods high in saturated fat n this study, researchers exposed the rodents to palmitic acid, a saturated fat, several times a day. When rodents were given the acid, they activate the gene PKCB, removing the effects of leptin and of insulin on appetite. Also see our article "Tips for improving nutritional health.While saturated fats produced this effect, unsaturated fats (such as oleic acid, a fatty acid found in olive oil and others), do not. This confirms the idea that all fats are not bad. Also see our article "Olive oil may help prevent obesity."
