What percentage of total daily calories should come from lipids?

• A. 30-35%
• B. 5-10%
• C. 50-60%
• D. 70-80%

Answer: (A)

The main idea here is how energy is distributed among the macronutrients. Fats should make up about a third of daily calories because fats provide essential fatty acids and fat-soluble vitamins and still fit within a balanced energy plan when paired with carbohydrates and protein.

Choosing a fat intake in the roughly 30–35% of total calories range aligns with common dietary guidelines. For example, on a 2,000-calorie day, 30–35% from fat equals about 600–700 kcal from fat, which is roughly 67–78 grams of fat (since fat has 9 kcal per gram). This amount supports necessary bodily functions without excessively displacing other nutrients.

The other options don’t fit typical guidelines: too low (5–10%) could miss essential fatty acids and vitamins; too high (50–60% or 70–80%) would crowd out carbohydrates and protein and, depending on fat type, could raise health risks.
