Hi, I’m 65 and have been doing the 5:2 for about 3 weeks now, and I have lost almost one and a half kilos – I’m down to 64.7. This diet really seems to work for me, and most of the effects have been positive – particularly my skin. I’ve always had good skin but it tended to get red either side of the nose (I’m prone to rosacea) – but that has much improved. I also look a lot less jowly, and so does my husband who’s doing this diet too.
As for the negative effects, the first couple of fast days left me with a headache – you really do have to keep yourself well-hydrated. Now I have a bottle of water or a mug of hot tea on the desk at all times, and keep sipping.
