Limited period of calorie-controlled dieting potentially aids in long-term weight maintenance
New findings on intermittent fasting shed light on weight loss and maintenance
In the realm of dieting, intermittent fasting (IF) has gained significant popularity in recent years. One common question people often ask is, "Is there an optimal time to eat during intermittent fasting?" A recent study presented at the European Congress on Obesity 2025 offers some enlightening answers to this question.
The Benefits of Time-Restricted Eating (TRE) for Long-Term Weight Loss
By limiting their eating windows to 8 hours a day, participants in the study experienced substantial weight loss and were able to maintain this loss for at least a year. The findings suggest that time-restricted eating could be an effective strategy for shedding excess pounds and, more importantly, maintaining weight loss over the long term.
Flexibility in Time-Restricted Eating
Worried about finding the right time for your eating window? Don't fret! Researchers found that the specific timing of meals wasn't as crucial as sticking to the 8-hour eating period. In this study, participants were given the freedom to choose their own eating window times, and all achieved similar weight loss results.
Simplified Approach to Dieting
Compared to traditional diets that focus on calorie counting and food tracking, time-restricted eating offers a more simplified approach. By concentrating on when to eat, rather than what to eat, dieters may find this strategy more manageable and sustainable in the long run.
Key Findings from the Study
- Weight Loss Maintenance: After 12 months, study participants who followed TRE maintained greater weight loss compared to those who did not restrict their eating window[5].
- Reduction in Waist and Hip Circumference: Significant reductions in waist and hip circumferences were observed in the time-restricted groups[5].
To Sum Up
The study indicates that time-restricted eating is a promising strategy for achieving and maintaining a healthy weight. While you might be wondering which specific foods to eat, concentrate on your eating window instead. Consider your daily routine and try to find an 8-hour period that suits your schedule and lifestyle, and get ready to experience the benefits that may come from time-restricted eating.
Additional Insights
- Time-restricted eating may lead to better cardiometabolic health outcomes by reducing snacking and overall calorie intake[2][3].
- TRE offers a more sustainable option compared to traditional low-calorie diets, as it eliminates the need for calorie counting and food tracking[2][3].

- Intermittent fasting, specifically Time-Restricted Eating (TRE), has emerged as a popular strategy for weight loss and management, particularly for long-term results.
- In the study presented at the European Congress on Obesity 2025, participants restricting their eating windows to 8 hours a day achieved significant weight loss and maintained this loss for at least a year.
- Interestingly, the specific timing of meals wasn't as crucial in this study, provided the 8-hour eating period was maintained, suggesting flexibility in TRE.
- Time-restricted eating offers a simplified approach to dieting compared to traditional methods that focus on calorie counting and food tracking.
- Key findings from the study include the fact that after 12 months, participants who followed TRE maintained greater weight loss compared to those who did not restrict their eating window, and a reduction in waist and hip circumferences were observed.
- The study suggests that time-restricted eating is a promising strategy for achieving and maintaining a healthy weight, with potential benefits for cardiometabolic health and offering a more sustainable option compared to traditional low-calorie diets.
