How to Avoid Weight Gain with HIT

The human body is at its peak, physiologically speaking, between the ages of about 18-29 years old. Bodily changes occur thereafter, like losses in strength and aerobic capacity coupled with changes in bodyweight and body composition. There is a significant, yet preventable, downward shift with each of those variables after the third decade of life. How to avoid weight gain becomes a central focus for the majority of our population after about the third decade.

5 Ways to Avoid Weight Gain: Focus on Lifestyle Changes

The following suggestions need to be done consistently each week in order to change the way you look and feel. It’s not some type of quick fix!

  • Never Stop Strength Training. This one is a must for each one of us, especially as we age. The key is building a strong base during the early years (teenage through 20’s) and then maintain that strength with a few weekly strength training sessions. Yes, for the rest of your life. Look at all the older people you know who don’t exercise and lead an un-active lifestyle. How are they doing with that?
  • Increase Activity. I’m not talking about long, slow, aerobic exercise here. The goal is to turn off and put down all screens each day. Then, work a little harder and find creative ways to increase your activity level each day. A good definition of physical activity is “all activities, at any intensity, performed during any time of day or night. It includes exercise and incidental activity integrated into daily activity.” For me, its about making sure I walk and move enough to move 5-7 miles a day (about 10-14,000/steps) on top of exercise.
  • HIT It Hard. HIT refers to high-intensity interval training. It can have a positive effect on fat-loss, prevent weight gain, and improve VO2 max. There is also a great deal of research on the benefits on cardiometabolic health (blood pressure, blood sugar levels, and cholesterol level). Try a minimum of 1-2 HIT sessions a week with multiple days of rest between bouts to take advantage of these benefits. This could be the key to how you avoid weight gain.

Nutrition Related

  • Watch What You Put into Your Mouth. It can all come down to being that simple. Begin to think of food as fuel for your body. Don’t eat it unless it’s high octane fuel that can help your body. We all know fad diets don’t work, long-term. Eating real, unprocessed food, like in the Mediterranean Diet, is the goal.
  • AVOID Added Sugar. We know it’s in everything. So a little is not a big deal. But try to eat less than 38 grams/added sugar/day/men and 25 grams/add sugar/day/women. Doing this will add years to your life and keep unwanted weight off, especially around the abdominal and hip area.

How HIT Improves Overall Health

One of the leading researchers on the benefits of HIT is Martin Gibala, PhD from McMaster University in Ontario, Canada. One of his many research studies (2014) looked at the effects of short-term interval training using a 10-minute protocol with only 1-minute of hard exercise. The results were various health improvements in overweight adults. In summary, the study showed 3-minutes of all out exercise performed within a 30-minute routine (includes warm-up & cool-down), 3x/week, improved cardiometabolic health factors. This study included 18 supervised training sessions over a 6-week period. As a result, improvements in the oxidative capacity of skeletal muscle, blood pressure and VO2 max were some of the outcomes.

How HIT Improves Body Composition

A second study, published in the British Journal of Sports Medicine (2019), compared the effects moderate-intensity (MOD) exercise with HIT. The research groups looked at 786 studies before choosing 36 that met their meta-analysis study criteria. Interval training and MOD both reduce body fat percentage. Interval training, however, provided a 28.5% greater reduction in total absolute fat mass compared to MOD. Other research has shown that HIT is superior to MOD in many other areas. HIT promotes greater increases in VO2max, ventricular function, improvements in insulin sensitivity, blood pressure, lower ratings of perceived exertion, higher levels of enjoyment and higher adherence than MOD.

Jefit Compliments HIT

Adding weekly HIT sessions with Jefit strength training is suggested if weight-loss and other cardiometabolic health benefits are the goal. Many of the Jefit home circuit-based training programs pair nicely with HIT sessions. The first is Advanced Bodyweight Circuit and a second option is a program I’m doing right now, Total Body Circuit. Enjoy and Stay Strong!
