Age effect: whey protein suppresses energy intake in young men and is dangerous for older

Age effect: whey protein suppresses energy

Nutritional supplements have become very popular in recent years. They are often used by young men to suppress the desire to eat, thereby controlling calories consumed. Nutritional supplements help to build muscle and their regular use helps to lose weight. The same supplements are often used by older people, however, as shown in a recent study, their use can have negative consequences for people of age.

An international team of scientists conducted a double study to find out how protein drinks affect the human body, depending on the age. 13 elderly men, whose average age is about 75 years old, and 13 young men, who are on average 23 years old, took part in the study.

All participants in the experiment were in good health. They had to consume four different drinks with a total volume of 450 milliliters. The control drink contained 2 kilocalories, and the other three drinks had a high protein content: whey protein 280 kcal, whey protein fat 280 kcal, whey protein carbohydrate 504 kcal.

Drinks were given for four days in the morning on an empty stomach. The energy level was determined three hours after taking the drink. It turned out that energy consumption after a pure whey protein drink significantly decreased in young men by about 100-150 kcal.

But it increased significantly in older men by 42-50 kcal. It was also found that the energy level after drinks made from whey protein with fats or carbohydrates was found to be reduced in young people, not in the elderly.

And this indicates that such nutritional supplements characteristically affect the weight control of young men, and not those who are at a respectable age. The scientists have also noticed that even after drinks, older men experienced an appetite that was not the case with the young people.

The young people, on the contrary, felt a decrease in hunger. The findings of the study confirmed that suppressing energy intake in response to whey protein-rich drinks in older people compared to younger men.
