Tried 5:2 for a month - no effect whatsoever! So for the past 3-4 months I have devised an approach that works for me! Basically by sticking to 3 meals a day (ie not snacking in between) and reducing portion size (so I still eat the foods I want - just not as much!) I have managed to eat 500 cals/day less. In addition I have started walking regularly every day which results in a further 500 cals/day. In total I am therefore averaging 1000 calls/day net loss. This has worked wonders for me and I have lost around 2.5 stone and 6 inches from my waist! I have tried dieting many times over the years but they were never sustainable as they involved eating things I don't like or cutting out things I do like. This approach however works for me and,after 4 months, I am sticking with it. Only downside is the expense of throwing out and replacing my wardrobe!
