Energy balance
In adult humans, obesity is primarily driven by excessive energy intake rather than reduced metabolic efficiency or energy saving mechanisms, as obese individuals actually expend more total energy than lean individuals due to larger body mass.
Stop blaming your metabolism for weight gain. Scientific evidence indicates that obese individuals actually burn more calories at rest and during activity than lean individuals because they have more body mass to move and sustain. The primary driver of obesity is consuming more energy than your body uses, not a biological inability to burn it. Focus on managing energy intake rather than seeking metabolic shortcuts.
The results of these studies show that obesity is not primarily due to energy saving mechanisms; it can be inferred from these data that the positive energy balance that leads to obesity is mainly due to an excessive energy intake.

More from this paper
- High-fat diets promote obesity in humans primarily by facilitating fat storage with minimal energy cost (0-2%) compared to carbohydrate conversion to fat, which is energetically expensive (25% heat loss), making high-fat diets more efficient for weight gain.Good
- Obese humans exhibit resistance to the effects of endogenous leptin, as high plasma leptin levels associated with large adipose mass fail to trigger the expected reduction in food intake or increase in energy expenditure.Good
