Exercise Not Key to Weight Loss? Research Points to Ultra-Processed Foods as 'Main Culprit'

• New research suggests exercise may not burn significantly more calories than a sedentary lifestyle.
• A study of over 4,200 people found active individuals burn similar calories to those with inactive lifestyles.
• The body adapts metabolism during exercise, reducing energy expenditure elsewhere to balance total calories burned.
• Anthropologist Herman Pontzer identifies ultra-processed foods like sweets, snacks, and ready meals as the primary cause of fat gain.
• While exercise has marginal impact on calorie burn, it remains crucial for overall health, strengthening joints, and improving cardiovascular health.
