How to Choose the Right Keto Bar (Nutritionist Tips)

  • Check net carbs: Aim for fewer than 5 g per bar.
  • Focus on fats & protein: Look for bars with 8–15 g fat and 8–20 g protein.
  • Watch the sweeteners: Allulose, stevia, and erythritol are better tolerated than maltitol.
  • Prioritize whole-food ingredients: Nuts, nut butters, coconut, seeds, collagen, grass-fed proteins.
  • Use bars strategically: Best as a snack or emergency meal—not your daily mainstay.
