Light drinking was once thought heart-protective. Updated evidence suggests the safest amount for longevity is none — but for many adults, cutting back is more realistic than quitting overnight.

How alcohol affects weight

  • Liquid calories do not satisfy hunger
  • Alcohol lowers inhibitions around food choices
  • Poor sleep after drinking raises next-day cravings
  • Beer and mixed drinks often include added sugar

Healthy eating does not have to be perfect. MealCoach.ai and Coach Kibo help you build better meals, understand what works for your body, and stay consistent — without shame or endless calorie math.
