In this program you eat like normal for 5 days (in moderation, of course) and fast for 2 days, sounds easy right?
With the fasting plans, many people experience health benefits at the same time as weight loss. On fasting days you eat low-calorie foods like green vegetables, white fish, and low-fat diaries. You’ll find plenty of recipes that will suit your recommended calorie intake while fasting inside the Recipes tab in the app. On non-fasting days you eat according to the general recommendations - a great and varied intake of fruits, vegetables, whole grain options and healthy fat sources (such as fatty fish, nuts and seeds). Remember not to overeat on normal days. Since you’ll eat a lot less on fasting days than on normal days, you may experience feelings of exhaustion, especially in the beginning. Do not plan social events (dinners, parties) or hard exercise on these days, do that on the non-fasting days instead. 
In this program you have the same recommendations as in 5:2, but just one single day of fasting.
Perfect if you have a life filled with social events and struggling to fit in two days of fasting. Has dieting ever been easier? If you experience stagnation in weight loss or need a challenge, switch to 5:2 - simple!
