Obesity is both a feature and a disease.
Obesity is both a feature and a disease.
Although China is not the country with the highest proportion of obese population, due to its huge population base, China has become the country with the largest obese population in the world in recent years
In recent years, low-carb diets have become popular on the Internet, especially sought after by people who lose weight, and once became the pinnacle of diet in the weight loss industry
Recently, researchers from the University of Worcester in the UK published a research paper titled "Low-carbohydrate diets and men's cortisol and testosterone : Systematic review and meta-analysis" in the journal "Nutrition and Health" .
The study suggests that a low-carb, high-protein diet may lower testosterone levels in men, which can lead to erectile dysfunction and lower sperm counts
For the study, the researchers analyzed the results of 27 studies involving 309 men with an average age of 27 years .
For the study, the researchers analyzed the results of 27 studies involving 309 men with an average age of 27 years .
Analysis of cortisol levels found that the low-carb diet increased resting cortisol levels within 3 weeks, but returned to baseline levels over the long term .
Analysis of testosterone levels found that participants in the low-carb group had significantly lower testosterone levels compared to the high-carb group, and further analysis found that this effect was limited to a high-protein, low-carb diet
Cortisol levels in the low-carb diet group
Cortisol levels in the low-carb diet groupIn addition, researchers have found that diets containing more than 35 percent protein can reduce testosterone levels by 37 percent , which is medically known as hypogonadism and can lead to symptoms such as sexual dysfunction and infertility in adults

The researchers said that too much protein accumulation can also lead to " rabbit starvation .
Most people's diets are about 17% protein, and the low-testosterone diet results in more than 35% protein , so for the average person, don't worry, but for people on high-protein diets, protein should be limited to no more than 25%
Insufficient testosterone has also been linked to chronic diseases such as heart disease, diabetes and Alzheimer's
In conclusion, this meta-analysis shows that a high-protein, low-carb diet may decrease testosterone levels in men and increase cortisol levels, which can lead to erectile dysfunction and lower sperm counts
