Does Exercise Genuinely Help In Weight Loss And Weight Maintenance? Researchers’ Viewpoints Vary

To Start With

Losing weight is one of the main reasons why so many individuals want to exercise.  We follow the conventional wisdom that dieting and exercise are the keys to weight loss. But a recent debate in the scientific community underlines the rising concern that the component of this advice that suggests “exercising more” may be incorrect. We will try to discover Does Exercise Genuinely Help In Weight Loss in this pots.

The limited total energy expenditure hypothesis, which contends that exercise won’t help you burn more calories overall because your body will make up for it by burning fewer calories after your workout, is at the center of the discussion. So even while exercising will improve your health in innumerable other ways, it won’t help you lose weight.

What the facts indicate

Those who have expressed an interest in this theory have emphasized the significance of thoroughly examining the data from all gold-standard trials. They cited a 2021 analysis of more than 100 exercise research that looked at the impact of aerobic, resistance, or high-intensity interval training in combination or alone on weight loss in humans. The study found that exercise programs under supervision do result in weight loss, albeit a little amount. That ends the discussion, right? You can easily go for an additional run to burn off those extra calories if you eat too much dessert, right?

Actually, not quite.

Exercise should help prevent weight regain after low-calorie dieting if increased physical activity burns more calories overall. But it can be difficult to keep the weight off after dieting. The few randomized controlled trials that explore whether exercise helps people maintain their weight are included in the same 2021 review. The outcomes, however, fell short of those for weight loss. Researchers discovered that adults’ weight regain was not prevented by six to twelve months of aerobic activity, resistance training, or both following dieting.

Adherence to exercise

What about adherence, though? Did everyone who participated in those studies engage in regular exercise? Only one randomized controlled trial on weight maintenance that reported an objective compliance rate, indicating that each exercise session was overseen by a trainer, was found in the 2021 review. This reveals the proportion of time that research participants really exercised as directed.

25 post-menopausal women who finished a resistance training program after diet-induced weight loss in that research had a compliance rate of only 64%. Participants in this program were required to come in and work out two to three times a week for a whole year. Keeping up with a program for so long and succeeding 64% of the time doesn’t seem all that horrible.

However, they continued to regain as much weight as the 29 women who were in the control group and weren’t participating in the exercise program.

Energy equilibrium

It’s important to balance the energy you get from eating and the energy you get from activity, according to many individuals. If exercising didn’t help you keep the weight off, perhaps you needed to exercise more frequently. In its 2009 policy statement on physical activity for weight maintenance, the American College of Sports Medicine called attention to this issue of exercise dosage and stated that it is unclear how much physical activity is necessary to maintain weight following weight reduction. Furthermore, it noted that there aren’t many randomized controlled trials in this field that track participants’ energy balance using cutting-edge methods.

The disappearing calorie puzzle

However, there is another aspect of the energy measurements from that 2015 study that is particularly intriguing. By the end of the trial, there was no discernible difference between the total daily caloric expenditure of the exercisers and the non-exercisers. And this despite the fact that the exercisers’ trainers confirmed they expended an additional 400–600 calories per session at their almost daily workouts. Why weren’t the additional activity calories included in the total number of calories burned each day?

The response to that query might assist in illuminating why exercise doesn’t always help you maintain your weight loss: Your metabolism adjusts to regular exercise by burning less calories while you’re not working out. According to the hypothesis that sparked the current discussion, overall energy expenditure is constrained.
