Most current dietary guidelines recommend limiting fat to what percent of total calories?

• A. 5%
• B. 30%
• C. 40%
• D. 10%

Answer: (B)

The idea being tested is the typical proportion of daily calories that should come from fat. Most current dietary guidelines set total fat intake in the range of about 20–35% of daily calories, with 30% commonly used as a practical target. This balance allows enough fat for essential fatty acids and fat-soluble vitamins while keeping overall energy intake in check. Choices that are too low, like 5% or 10%, would make it hard to obtain essential fats; a choice as high as 40% pushes fat beyond the recommended upper limit and risks excess calories. So 30% best reflects the usual guideline.
