What works for one person may not be the same for another. But I wanted to post a bit about my current experience. When I began doing the 5:2 diet (very low calories/fasting two days a week) I found it was brilliant for one with little willpower to want to feel like I was "dieting" or watching what I ate 24/7. I will always be thankful for being introduced to the 5:2 diet. I think, from my experience, if you are used to eating quite a lot of food or bad foods it is a slow way of cutting you back without overwhelming you. It's easier to "go without" all your treats if you know you can have them back the next day.
Then the true magic begins ... As you get used to having much less on your fast days you stop wanting so much on your normal days. And .. I think... recognise real hunger from boredom hunger.
Anyways... I'm not going to list anymore of the vast benefits of the 5:2! But there was some downsides. It was much harder to stick to fasting when any stressful situations arose. Not looking forward to the next day as you know it's 'diet day'.
Before December I found I had to count calories on my non-fasting days and became much more aware of what foods were giving me enormous amounts of calories for little pay off. Recently I decided to drop the fasting days and calorie count everyday. I use the NHS BMI calculator to give me my weekly allowance of calories and then divide them up to allow me more on weekends and less on week days.
And I'm loving it! I feel much better not having fast days and I look forward to my meals every day! My system seems more stable too! Less constipation!
Im not saying one method was better than the other as when I began my weight loss journey I wasn't in the right place to make the changes to my diet that I have now. 5:2 helped me with that!
This weight-loss lark is definitely a journey and small steps can be better than jumping in at the deep end and trying to change yourself too fast!
