The 16/8 diet involves abstaining from food for:

• A. 8 hours per day
• B. 12 hours per day
• C. 16 hours per day
• D. 24 hours per day

Answer: (C)

The main idea is time-restricted eating, where you divide the day into fasting and eating windows. The 16/8 pattern means you fast for 16 hours each day and eat during an 8-hour window. This is why abstaining from food for 16 hours per day fits the regimen. For example, you might finish dinner by 8 p.m. and begin eating again at noon the next day, giving a 16-hour fast. The other durations don’t match this pattern: 8 hours would be an inverted 8/16, 12 hours would be a 12/12 schedule, and 24 hours would be a full-day fast, which isn’t the intended daily structure of the 16/8 approach.
