The 5:2 intermittent fasting diet isn't for everyone, but the way of eating — which includes five days of regular eating and two days of fasting — is having a moment. Here's the draw: By restricting calories down to 500 or 600 on fasting days, followers don't have to worry about counting calories or macronutrients on the other days.

Tips for a Successful 500-Calorie Day

When your calories are restricted, the foods you choose really matter.

  • Make sure you have adequate protein and a balanced source of carbohydrates while fasting to maximize your energy. Plus, sufficient protein will help to maintain your muscle during the fast, which will help with your weight-loss efforts (muscle burns more calories than fat).
  • Use herbs and spices — like crushed red pepper, garlic, rosemary, ginger, basil and salt — to increase the flavor and satisfaction of your meals without adding calories.
  • Sauces, fats and oils should be avoided as they can quickly add calories without much nutritional value.
  • When cooking meats, baked or broiled is best to limit any extra calories, and vegetables should be steamed.

How to Handle Normal Eating Days

While there are no restrictions on your normal eating days, it's still important to make sure your non-fasting days provide balanced nutrition. Meals made from whole-food sources like whole grains, lean meat or fish and fruits and vegetables without added sweeteners will maximize your nutrition throughout the week.

Incorporating physical activity is also super important to maintain muscle mass and endurance during the 5:2 fasting plan. The Centers for Disease Control and Prevention (CDC) recommend 150 to 300 minutes of moderate-intensity aerobic physical activity each week, such as walking or biking. Schedule workouts on your normal eating days rather than your fasting days to ensure you have enough energy and the right nutrition for recovery.

Can 5:2 Fasting Help You Lose Weight?

Intermittent fasting can reduce your overall calorie consumption throughout the day by restricting the time you are allowed to eat. An October 2014 study in ​Translational Research​ found that intermittent fasting one to three days a week (following the same model as a 5:2 fasting plan) is equally effective as calorie restriction for weight loss.

Intermittent fasting may also help dieters avoid the metabolic process that causes your body to stop losing weight during a weight-loss attempt, often referred to as a weight-loss plateau. A February 2018 study in the International Journal of Obesity found alternating periods of fasting with periods of energy balance — or normal eating — allowed research participants greater weight and fat loss. So, while more research needs to be conducted, intermittent fasting does show promise for weight-loss hopefuls.
