Exercising for weight loss rarely works, science shows

Recent scientific findings suggest that exercising to lose weight may not be as effective as many believe. While physical activity is essential for overall health, studies show it rarely results in significant weight loss on its own.

Studies by Herman Pontzer, an evolutionary anthropologist at Duke University, show that active people, like runners racing across the US, burn the same amount of calories as a person with a sedentary lifestyle.

One reason is the body’s ability to adjust its energy expenditure.

When people increase their activity levels, their bodies compensate by reducing calories burned through other processes, such as decreasing non-exercise movements.

Furthermore, exercise can trigger increased hunger, leading many to consume more calories, often offsetting the energy burned during physical activity.

Research also highlights that while exercise temporarily boosts metabolism, the effects tend to balance out over time, making weight loss difficult.

Experts suggest that sustainable weight loss is more achievable through a combination of a balanced diet, controlled calorie intake, and consistent exercise.

Focus on exercise for its health benefits, like reducing inflammation and improving mental well-being, rather than expecting it to be the sole driver for weight loss.
