The 5:2 lifestyle comes in a range of varieties. The original was 500 calories for women and 600 calories for men on 2 non-consecutive fast days a week. Dr. Michael Mosley has recently revised this to 800 calories as almost as effective and more achievable for some people. There is also a potential split between whether this is achieved in one meal or across two. When I’m at home I am just as happy to eat dinner only but when I’m at work I prefer to have lunch and dinner. So this meal is a little higher in calories than most of my 5:2 meals, we eat it on non-fast days.

This meal came in at 546 calories/serve using Casa Barelli tomato and mozzarella tortellini (363 calories/serve). The sauce itself is 213 calories so you could reduce the total with a different pasta (wholemeal being a better choice).
