A recent study published in the journal Obesity indicates that individuals with a strong hereditary predisposition to weight gain may significantly lower their risk of developing obesity by consuming their meals earlier in the day. The research involved over 1,100 overweight participants who underwent a dietary treatment program and were monitored for three years. Scientists analyzed both their genetic data and eating patterns, particularly the timing of their main meals.
Key Findings on Meal Timing and Genetic Risk
The findings revealed a significant correlation for those with a high genetic risk of obesity, as identified by the polygenic risk score for BMI (PRS-BMI). For this group, every hour of delay in consuming their main meal led to an increase in their Body Mass Index (BMI) by more than 2 kilograms per square meter. Conversely, participants with a high genetic risk who ate earlier in the day, closer to noon, were more successful in maintaining their weight post-treatment. Interestingly, this dependency was not observed in individuals with a low genetic risk for obesity.
Researchers emphasize that for carriers of the so-called “obesity gene,” the timing of food intake can profoundly impact the effectiveness of weight loss and management efforts. Specifically, late lunches and dinners, especially those consumed after 3 or 4 PM, appear to diminish the chances of long-term success in weight control for these genetically predisposed individuals.
Personalized Approach to Obesity Prevention
The study`s authors propose that adjusting meal times offers a simple, cost-effective, and personalized approach to the prevention and treatment of obesity. This strategy is particularly valuable for people with an inherited tendency to gain weight.
In related research, scientists previously linked obesity to an excess of oleic acid, a component found in olive oil. This acid has been shown to accelerate the formation of fat cells, potentially contributing to the accumulation of excess body weight.
