Complementary Hypotheses on Contributors to the Obesity Epidemic.

Area of Science:

• Public Health
• Epidemiology
• Nutrition Science

Background:

• Obesity rates are increasing across all demographics globally.
• The causes of the obesity epidemic are not fully understood.
• Food marketing and reduced physical activity are commonly cited as primary drivers.

Purpose of the Study:

• To explore factors beyond the "big two" (food marketing, reduced physical activity) contributing to the obesity epidemic.
• To identify additional influences on body fatness.

Main Methods:

• This is a perspective piece, building on existing literature.
• It synthesizes current knowledge and proposes additional contributing factors.

Main Results:

• The "big two" factors may not solely explain the obesity epidemic.
• Other factors likely interact with "the big two" to influence obesity.
• These factors impact energy intake, energy expenditure, and nutrient partitioning.

Conclusions:

• A multifactorial approach is needed to understand and address the obesity epidemic.
• Investigating additional contributing factors is essential for developing comprehensive public health interventions.
