About the study
In a randomised clinical trial in Iran, individuals meeting the inclusion criteria were randomly assigned to either the intervention group (low-calorie diet with increased protein percentage) or the control group (standard protein percentage) using block stratification. The participants' psychometric characteristics were then evaluated.
The findings
The results of the study showed that low-calorie diets with a high-protein percentage can significantly improve psychometric variables in obese people. It found that 15 days on this diet resulted in decreased symptoms of anxiety and depression. After 30 and 60 days, participants adhering to this diet also reported lower stress scores.

Obesity: What you need to know
Obesity has reached 'epidemic proportions', according to the World Health Organization. It's a chronic disease that affects millions of people worldwide and has become a major health problem: By 2035, more than half of the world's population, more than 4 billion people, could be obese or overweight, according to the World Obesity Atlas 2023.
Obesity is a complex disease that can occur at any age and affects adults and children alike. The World Health Organization (WHO) defines obesity as ‘abnormal or excessive fat accumulation that presents a risk to health’. Obesity is typically measured using the body mass index (BMI), where individuals with a BMI of 30 or higher are classified as obese. BMI is calculated as one’s weight in kilograms divided by the square of their height in meters.
What are its causes and symptoms?
Genetics, lack of exercise, bad eating habits, psychological issues, health problems, social and economic conditions, drugs, pollutants, and more can all contribute to the development of obesity.
Symptoms related to excess fat and body weight include difficulty doing physical activities, pain in different parts of the body and even osteoarthritis, a degenerative joint disease. Obesity can also make it difficult to breathe at night, a condition called sleep apnea.
