Dieting: proxy or cause of future weight gain?

Area of Science:

• Behavioral Science
• Obesity Research
• Nutritional Science

Background:

• The link between dieting and body mass is complex and debated.
• Distinguishing dieting's direct effects from its role as a risk indicator is crucial for understanding weight management.

Purpose of the Study:

• To differentiate dieting as a cause of weight gain versus a risk factor for weight gain.
• To clarify the relationship between weight loss/regain cycles and ultimate body mass.
• To explain why dieting history in non-obese individuals indicates future weight gain susceptibility.

Main Methods:

• Review of evidence on diet-induced weight loss, weight suppression, and weight regain.
• Analysis of dieting history as a proxy risk factor for weight gain.
• Conceptual distinctions between attained body mass and potential body mass without dieting.

Main Results:

• Diet-induced weight loss accelerates weight regain.
• A history of dieting does not cause weight gain beyond what would naturally occur.
• Dieting in non-obese individuals acts as a proxy risk factor, not a direct cause of future weight gain.

Conclusions:

• Dieting hastens weight regain but does not cause excessive weight gain over time.
• Dieting history in non-obese individuals reflects vulnerability to weight gain in obesogenic environments, rather than causing it.
