One of the good things about 5:2 is that you never have to be more than 24 hours away from a decent feast. And I find that as long as one is super-strict in staying below the 500/600 calories limit on fasting days you really can eat and drink as normal on the non-fasting days.
It’s quite surprising how much stuff (as long as it’s the right stuff) one can eat on a fasting day. We do it with home-made, seed-intensive, cereal for breakfast (with milk) and steamed fish/chicken with unlimited amounts of green vegetables for a combined lunch/dinner. Baked beans and tinned tuna are really low in calories too. It’s really not that bad. We still have milk in our tea and have some fruit juice. But, on the fasting days, by completely avoiding bread, butter, potatoes, pasta, puddings and alcohol we stay just within the limit. If I get hunger pangs it’s surprising how well a glass of water works.
After each successful fasting day I reward myself by sneaking out for breakfast at our local baker and wolf down one of their fabulous bacon rolls and some naughty cheese straws.
I find that I lose nearly two pounds on each successful fasting day of which I regain one pound again afterwards; but that’s a net loss of nearly a pound (two pounds a week) which equates to a reliable weight loss of eight pounds (ie half a stone) a month. Temptation gets the better of me sometimes but I probably manage 3 successful fasting weeks a month. But trying to lose the final half stone, which would get me where I want to be BMI-wise, is taking longer. I’m content that, for me, the 5:2 is now an ongoing way of life and not merely a short-term diet.
As one of the responses above points out, there is some evidence that on the fasting days one’s temporarily underemployed metabolic systems look for other things to do to relieve their boredom. Having a go at repairing some damaged neural pathways seems to be quite high up on their ‘to do’ list. My grossly over-simplified clinical understanding is that 5:2 is a really good, steroid-free, way of helping one’s MS. No doubt a trained medic would cringe at my banal analysis but it seems to work and that’s good enough for me.
I very much hope other people with MS will give the 5:2 a go and share on this link how they get on. There’s nothing to lose!
