What happens when you combine time-restricted eating (TRE) and high-intensity interval training (HIIT)?

TRE and HIIT - both habits thought to promote longevity…but what happens when they are both added into your health routine? New research sheds a light on the answer.

A refresher: TRE is when you follow a schedule of when you eat (and when you don’t eat) during the day. HIIT stands for high-intensity interval training (HIIT) which pertains to alternating between fixed intervals of high-intensity and low-intensity or resting exercises.

Study Summary

This new research, which included 131 overweight or obese women, found that:

  • After 7 weeks of combining these two lifestyle habits, individuals had improved HbA1c, or average long-term glycemic control, as well as reduced fat mass and visceral fat.
  • Participants also improved in cardiorespiratory fitness.

These study results might not be as generalizable since they apply to overweight and obese women. There is a need for more studies to continue to cement these findings and also investigate the benefits for healthy populations.

The Hearty Take

At Hearty, we believe these lifestyle habits are great ways to promote health. They are easier to adopt than say calorie counting (which usually doesn’t work) or 2 hour long daily cardio workouts. If you’re looking for a relatively simple way to upgrade your diet and exercise habits to enhance your health, consider HIIT and TRE.
