Time-Restricted Eating and Resistance Training for Weight Loss
Share
Introduction
Losing weight and improving fitness doesn’t always mean spending hours at the gym or following extreme diets. For young adults struggling with overweight or obesity, combining two simple strategies—time-restricted eating (TRE) and resistance training (RT)—can lead to noticeable changes in body composition, mood, and overall well-being. A recent study explored how these two approaches work together to support healthy weight loss and mental health.
What Is Time-Restricted Eating (TRE)?
Time-restricted eating means eating all your meals within a fixed time window during the day—usually 8 to 10 hours—and fasting during the remaining hours. In this study, participants followed a 10-hour eating window of their choice (between 8:00 AM and 8:00 PM), without changing what they ate, just when they ate.
This simple change led to weight loss and reduced waist and hip measurements, even without changing the food itself. TRE was found to be especially effective when combined with structured resistance training.
How Resistance Training (RT) Fits In
Resistance training involves strength-building exercises like squats, presses, and curls using weights or resistance machines. In this study, participants trained three times a week with exercises targeting both the upper and lower body. Each session lasted around 45 minutes and included guided, supervised movements.
RT alone helped reduce body fat and build lean muscle. When combined with TRE, it prevented muscle loss that can sometimes happen with dieting alone. This combination helped participants lose weight and fat while maintaining muscle mass—a key factor in long-term health and strength.
What Changed After 8 Weeks
Here’s what happened by the end of the study:
- Body weight and BMI dropped significantly with TRE and TRE+RT.
- Fat mass dropped more with TRE+RT than RT alone.
- Muscle mass decreased with TRE alone, but was preserved when RT was added.
- Waist and hip size reduced with both TRE and TRE+RT, not with RT alone.
- Diastolic blood pressure lowered with RT and TRE+RT.
- Anxiety levels improved slightly in the TRE+RT group.
- Sleep quality improved with RT and TRE+RT, but not with TRE alone.
Why It Matters
Weight loss often comes at the cost of muscle loss, which can slow metabolism and affect physical performance. TRE alone helped reduce weight, but it also reduced lean body mass. Adding resistance training helped preserve muscle, making the overall result healthier and more sustainable.
Also, improving sleep and lowering anxiety—even slightly—adds another layer of benefit for people trying to make healthy lifestyle changes.
Conclusion
If you’re looking for a practical, non-extreme way to lose weight and improve your health, combining a simple eating window with regular strength training could be a smart and sustainable strategy. It helps with fat loss, protects muscle, and may also boost mood and sleep—making it a well-rounded approach to better living.
