A recent study highlights that combining time-restricted eating with high-intensity functional training enhances body composition and cardiometabolic health more effectively than either method alone, offering a promising strategy for improved health outcomes.

According to a recent study published in the journal PLOS ONE, integrating time-restricted eating with high-intensity functional training could enhance body composition and cardiometabolic parameters more effectively than either approach alone. The research was conducted by Ranya Ameur and Rami Maaloul from the University of Sfax, Tunisia, along with their colleagues.

Changes in diet and exercise are well-known ways to lose weight and improve cardiometabolic health. However, finding the right combination of lifestyle changes to produce sustainable results can be challenging. Prior studies indicate that time-restricted eating (which limits when, but not what, individuals eat) and high-intensity functional training (which combines intense aerobic and resistance exercise) may be beneficial and easier for individuals to commit to long-term.

In a new study, researchers investigated the impact of time-restricted eating and high-intensity functional training on body composition and markers of cardiometabolic health such as cholesterol, blood glucose, and lipid levels. 64 women with obesity were assigned to one of three groups: time-restricted eating (diet only), high-intensity functional training (exercise only), or time-restricted eating plus high-intensity functional training (diet + exercise). Participants following the time-restricted eating regimen ate only between 8:00 am and 4:00 pm. Those in the functional training groups worked out three days per week with an instructor.

After 12 weeks, all three groups had significant weight loss and decreases in waist and hip circumference. Likewise, all groups showed favorable changes in lipid and glucose levels.

Some differences were seen between groups. For example, fat-free mass (a combination of lean mass and skeletal muscle mass) and blood pressure improved in the diet + exercise and exercise groups but did not change in the diet-only group.

Participants in the diet + exercise group generally experienced more profound changes in body composition and cardiometabolic parameters than either diet or exercise alone.

The researchers noted that this is a relatively small study, and it is difficult to tease out the contributions of specific exercise routines or of time-restricted eating and calorie reduction since both groups reduced their calorie intake. However, they note that combining time-restricted eating with high-intensity functional training might show promise in improving body composition and cardiometabolic health.

The authors add: Combining time-restricted eating with High Intensity Functional Training is a promising strategy to improve body composition and cardiometabolic health.
