Inactivity and Obesity: Causes, Risks, and Costs

  • Inactivity and obesity are significant issues with personal and societal costs.

  • Processed Foods: High sugar and starch content in processed foods.
  • Increased Portion Sizes: Encouraging overeating, leading to stomach expansion and increased food requirements.

Health Risks Associated with Inactivity and Obesity

  • Coronary artery disease
  • Stroke
  • Type 2 diabetes
  • Some cancers
  • Osteoporosis
  • Kidney diseases
  • Chronic obstructive pulmonary disease
