The most important nutritional factor for the health of the body is protein, with the average American consuming around 20g of it a day, according to the National Institutes of Health (NIH).
The high-fat diet, on the other hand, is usually seen as a good option, with experts claiming that it’s a more balanced and nutritious way to eat.
However, this isn’t always the case.
A new study from the University of North Carolina found that even people with moderate protein intake have elevated prolactine levels, which can lead to weight gain.
Researchers looked at 2,622 men who had been followed for a year or more.
After one year, their prolactide levels had increased by 18%.
The researchers said it was the first time this was seen in the general population.
“The elevated prolactic hormone levels in this population are consistent with an increase in prolactate hormone,” the authors wrote.
The findings, published in the Journal of the American Medical Association (JAMA), suggest that a high-carbohydrate diet could lead to a similar increase in hormones, and is likely linked to an increase of cortisol levels.
The hormone cortisol has been linked to weight and fat gain, and may be involved in a number of conditions including diabetes, cardiovascular disease, and cancer.
“In general, a higher protein diet is associated with higher circulating levels of circulating prolactone, and higher circulating cortisol levels are associated with elevated circulating prolacortin levels,” the researchers wrote.
“This finding may be relevant to the use of high-calorie, high-nutrient, high protein diets for weight loss or to the effects of increased dietary fat consumption on obesity.”
