Sounds like a lot of medical work has gone into this one. Seems predominantly aimed at health benefits first weight loss second. Am starting fast day today
2 tins of Heinz Big Soup and couple of coffees is just under 600 cals so easy start. If it works out well might use my remaining Madal Bal for fasting days as that is about 500 cals/day. Although the lure of a quick 3 stone weight drop is a bit hard to waste.
