Weighing the differences between the 5:2 and 16:8 approaches to intermittent fasting and how to pick the best plan for your needs.

Intermittent fasting has become a go-to approach for weight loss, health improvement, and meal planning simplicity. Two of the most popular intermittent fasting methods are the 5:2 plan and the 16:8 plan. While the two have similarities, there are some key distinctions.

What is the 5:2 Intermittent Fasting Plan?

In the 5:2 intermittent fasting plan, you eat normally for 5 days of the week and restrict calories to 500-600 per day for the other 2 days. On the 2 fasting days, focusing on low-calorie foods like vegetables, fruits, lean protein, and whole grains is best.

The 5:2 approach involves a more extreme calorie reduction, though the 2 fasting days allow flexibility to choose the days that fit your schedule best. This method promotes faster initial weight loss compared to 16:8 intermittent fasting.

What is the 16:8 Intermittent Fasting Plan?

The 16:8 intermittent fasting plan involves fasting for 16 hours daily and restricting food intake to an 8-hour window. For instance, you might skip breakfast and eat between 12 pm-8 pm daily.

During the 8-hour eating window, you can generally eat normal meals without calorie restriction like the 5:2 plan. The 16:8 method has a longer daily fast more aligned with the natural overnight fast.

Choosing the Right Intermittent Fasting Method

Both intermittent fasting approaches can help facilitate weight loss, reduced insulin resistance, lower blood pressure and cholesterol. The 5:2 method prompts faster initial weight loss, while the 16:8 plan may be easier to maintain long-term.
