Does Peanut Butter or Tahini Make You Gain Weight? The Spoonful Calorie Trap

When people search Google for "calories in peanut butter" or "does peanut butter make you gain weight", they are often met with extreme crash diets or conflicting rules.

Step-by-Step Action Plan: How to Apply This Daily

  1. Action Step 1: Peanut butter is primarily a healthy fat source (50% fat, 25% protein)—count it toward your fat macros rather than your primary protein target.
  2. Action Step 2: Buy jars where the ingredient list reads only 'Peanuts (and salt)', avoiding hydrogenated palm oil and added icing sugar.
  3. Action Step 3: Always portion onto your plate with a measuring spoon and close the jar before eating.
  4. Action Step 4: For big peanut flavor in smoothies or yogurt at 70% fewer calories, powdered peanut butter (50 kcal, 6g protein per 2 tbsp) is a great hack.
