At the beginning of the year I followed the 5:2 eating plan. I've gone a bit off-piste lately, but determined to get back into the routine. More importantly for me, my weight hasn't gone back on. I would thoroughly recommend this plan, as on two days I don't have to think about lunch and take myself out for a long walk instead. I plan my weekly meals before I do my food shop, which for me is great. If you're not sure on 2 fasting days, I would urge you to give it a go (as long as your GP confirms it's ok, as it's not for everyone). You still get to eat on the 2 fasting days, just very reduced calories. Whatever route you take to loose your weight and get healthier - good luck.
