I am doing the 5:2 fast as well. However I don't consider it a true fast because I am eating 3 meals a day. I try to keep it as close to 500 calories as possible on 2 days a week. Actually I am doing the fast the same days I try to do a detox diet, on Thursdays & Saturdays because I weigh in on Sundays. Check out my weight history. I am in the third week of the 5:2 fast challenge. And what it comes down to in simplest terms is I just pick out 2 days a week to have Greek yogurt for breakfast and salads for lunch & dinner with a little salmon at the dinner meal. Snacks are limited to almonds, an apple and plenty of celery and green tea. The other 5 days of the week eat normally. I think this is a great jump start for dieting if you find yourself on a plateau.
