• Whether “calories in, calories out” is physiologically accurate
• The many misconceptions related to “calories in, calories out”
• Why a calorie deficit is NOT required for fat loss
• Why “calories in, calories out” does not mean that eating less and exercising more is good advice for fat loss
• What most people miss when it comes to “calories in, calories out”
