A study of over 1,100 people found that exercise may not be effective in losing weight but helps maintain weight loss. Regular physical activity was linked to health benefits such as better cholesterol and lower inflammation.
The basic principle of weight loss is simple: consume fewer calories than you burn, and you'll lose weight. However, this isn't always easy or straightforward. Many people add exercise to their routine to help tip the balance. But research shows that exercise may only have modest effects on weight loss.
There are several reasons why exercise doesn't always result in huge amounts of weight loss. Exercise can stimulate appetite, leading to increased food intake. People may also subconsciously move less throughout the rest of the day after doing a workout, which means exercise may have less impact on their overall calorie deficit. The body also becomes more efficient over time – burning fewer calories while doing the same activity.
Despite this, exercise still plays a crucial role in health, especially when it comes to maintaining weight loss. A study of over 1,100 people found that physical activity was strongly linked to maintaining weight loss after losing weight. Exercise was also associated with measurable health improvements such as better cholesterol, lower inflammation, and improved blood sugar control.
The reasons behind this paradox aren't fully understood, but several mechanisms may offer an explanation. One factor is our resting energy expenditure (the amount of calories our body burns when doing nothing). When we lose weight, our resting energy expenditure decreases by more than you would expect for the amount of weight lost. This can contribute to weight regain. But exercise raises total daily energy expenditure, which can help to partially offset this.
Another factor is muscle mass. Weight loss usually results in the loss of both fat and muscle. Losing muscle lowers resting energy expenditure, which can contribute to weight regain. But exercise, especially resistance training (such as Pilates or lifting weights), can help preserve or even rebuild muscle mass.
Why It Matters
This study is important for Indian students because it shows that regular physical activity is crucial not just for losing weight but also for maintaining weight loss and improving overall health. As India grapples with rising obesity rates, this research highlights the importance of incorporating exercise into daily routines to prevent chronic diseases such as heart disease and type 2 diabetes.
Key Facts

- Exercise raises total daily energy expenditure, which can help offset weight regain.
Key Terms
- Resting Energy Expenditure
- The amount of calories our body burns when we're not actively doing anything.
- Metabolic Adaptation
- When our body becomes more efficient at burning calories over time, making it harder to lose weight.
