Olive oil is mostly monounsaturated fat. Replacing butter and refined oils with olive oil is associated with lower cardiovascular risk in large studies — not because oil burns fat, but because it supports a healthier fat profile overall.

How to use it daily

  • Drizzle on salads and roasted vegetables
  • Use for low-to-medium heat sautéing
  • Finish soups with a small pour for flavor
  • Measure if weight loss has stalled — fats are calorie-dense

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.
