I've yo-yo'd for 15 years doing green days on SW as I am a former carbo-holic. However this year I turned 50 and that was something of a slap in the face and I decided I needed to do something once and for all. I gave up white carbs and switched to 5:2 fasting and calorie counting on my eating days. I also started running for the first time in my life and have found that I LOVE doing so. To be honest, it was as if my body said "At LAST!" and faithfully dropped a good two pounds a week for me. I hit target a couple of weeks ago and for a day or so I was saying "My journey is over" Of course, now I realise that only the first LEG of my journey is over.... now I have to do the more difficult part that is maintenance.... although because I completely overhauled my eating habits and run/go the gym 3 times a week, I am more confident that the changes I made this year are for life. My journey will never be over, but I hope the fight for it will lessen in time. I've had compulsive over-eating tendencies in the past so each day is a constant battle, but it isn't always difficult... I have good days and bad days and sometimes I weaken and have a slice of cake, which gives me indigestion these days. And then I make myself eat less the next day, or run further to burn off the calories - in my head it's the trade off.
I FIRMLY believe that you need to experiment and tailor an eating and exercise plan purely to your own body and that what works for someone else won't necessarily work for you.....
