The 16/8 diet involves abstaining from food for:
a. 8 hours per day
b. 16 hours per day
c. 8 days per month
d. 16 days per month
The correct answer and explanation is :
Correct Answer: b. 16 hours per day
The 16/8 diet, also known as time-restricted eating, is a form of intermittent fasting that involves fasting for 16 hours and eating only during an 8-hour window each day. For example, a typical eating window might be from 12:00 PM to 8:00 PM, during which you consume all your daily calories. Outside of this window—during the 16-hour fasting period—you abstain from all food, although water, black coffee, and other non-caloric beverages are typically allowed.
The rationale behind the 16/8 diet is that giving your body an extended break from food allows it to enter a metabolic state called ketosis, where it begins to burn stored fat for energy. During the fasting period, insulin levels drop, which facilitates fat burning and can help improve insulin sensitivity. Research also suggests intermittent fasting may offer benefits such as improved metabolic health, weight loss, and reduced risk of type 2 diabetes.
This diet is popular because it’s relatively easy to adopt. Unlike other diets that restrict what you eat, the 16/8 method focuses on when you eat. This flexibility makes it easier for many people to stick with it long-term. However, it’s still important to eat nutrient-dense, balanced meals during the eating window. Overeating or consuming unhealthy foods during the 8-hour period can negate the benefits.
The 16/8 diet may not be suitable for everyone—especially pregnant women, people with diabetes, or those with a history of eating disorders. As with any major dietary change, it’s best to consult a healthcare provider before starting.
