  3. Understanding the Link Between Diet and Obesity

  Obesity doesn’t develop overnight. It results from a complex mix of diet, lifestyle, genetics, and environment. Still, food choices play the most decisive role.

  Studies show that:

  • Ultra-processed foods significantly increase obesity risk (Harvard, 2023).

  • Diets high in sugar and refined carbs disrupt insulin and promote fat storage.

  • Low-protein diets reduce satiety and trigger overeating.

  That’s why structured obesity management always begins with dietary changes — before medications, before surgery.

  7. Combining Diet with Lifestyle Strategies

• 

• Diet alone works best when paired with other lifestyle habits:

  • Exercise: Aim for 150–300 minutes weekly.

  • Stress Management: High stress raises cortisol, linked to belly fat.

  • Sleep: 7–9 hours nightly keeps hunger hormones balanced.

  For individuals struggling despite these changes, medical interventions like gastric sleeve surgery can be considered.
