Earlier studies have shown that there is a bidirectional relationship between low-calorie diets and depression in obese people. The study was designed and conducted to examine the effects of a low-calorie, high-protein diet on psychometric variables in obese individuals. The study was published in Nutritional Neuroscience.
About studies
In a randomized clinical trial in Iran, individuals meeting the inclusion criteria were randomly assigned to either an intervention (low-calorie high-protein diet) or a control (standard protein) group using block stratification. Participants’ psychometric characteristics were then assessed.
Conclusions
The results of the study showed that low-calorie diets with a high percentage of protein can significantly improve psychometric variables in people with obesity. It turned out that 15 days of this diet led to a reduction in symptoms of anxiety and depression. After 30 and 60 days, participants who followed this diet also reported lower stress scores.

More details
There were no significant differences in enrollment between the two groups with respect to anthropometric variables, body composition, and physical activity. Similarly, no significant differences were observed between the two groups in terms of psychological variables (depression, anxiety, and stress).
However, the intervention groups had significantly lower depression and anxiety scores 15 days after the intervention. After 30 and 60 days of intervention, there were significant differences between the two groups in terms of depression, stress, and anxiety, indicating a relative improvement in psychometric variables in the intervention group.
Obesity: what you need to know
According to the World Health Organization, obesity has reached epidemic proportions. It is 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, may be obese or overweight, according to the World Obesity Atlas 2023.
Obesity is a complex disease that can occur at any age and affects both adults and children. The World Health Organization (WHO) defines obesity as “an abnormal or excessive accumulation of fat that poses a health risk.” Obesity is usually measured using body mass index (BMI), where people with a BMI of 30 or higher are classified as obese. BMI is calculated as a person’s weight in kilograms divided by the square of height in meters.
What are its causes and symptoms?
Genetics, lack of exercise, unhealthy eating habits, psychological problems, health problems, social and economic conditions, drugs, pollutants, and more can contribute to the development of obesity.
Symptoms associated with excess body fat and weight include difficulty exercising, pain in various 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.
