Yeah, never mind the pesky scales not-a-girl Phil......how about the trousers???
I'm with Julianna on that one....plus, ask yourself:
Am I eating less junk than before?
Am I moving more than before?
Bet you the answer to both those questions will be "yes".......so you are making great healthy changes....even if the-things-that-lurk-in-the-corner-of-the-bathroom don't reflect it. They really are sooooo one-dimensional anyway.
Also, what about all the good you are doing yourself from the inside by fasting? Maybe it'll take the outside a little time to catch up...but you really are going great guns! Please remember that.
Having said all that ra-ra stuff, I do honestly sympathise with your frustration. But, like the rest of us, you are in it for the long haul Phil & every week that goes by will embed the 5:2 habit deeper into your psyche.......
If they have too much of a negative effect on you, why not banish the scales for a few weeks & just concentrate on keeping to your TDEE on non-fasting days....whilst continuing to up the exercise whenever you can. The kids will love you for it...as there's nothing kids like more than Dad (or Mum) joining in........
Finally, just a thought.....are you much into the World Cup & beer? If you are, these past few weeks won't have been too helpful maybe....
Best of luck - you can do it!
