Hi Sam!
I think that you are doing great! It's awesome that you are so motivated and dedicated. You are an inspiration to us all.
Just a question - Does the Cohen's diet that you where on ban carbs? I've also been a bit weary of carbs. But after I've consulted with my dietitian, she told me that carbs are the fuel of the body and that it gives you energy.
She then placed me on a diet where I am eating much more carbs than usual and she said that it will make me lose weight. So I'll just wait and see.
I am exercising my butt off (excuse my language). I am doing yoga/Pilates classes in the mornings and then I also weight train for 3 days a week, have one ballroom dancing class once a week and my fiancé and I are also going to play squash twice a week.
Good luck, but I think you are doing great. The only thing that I am concerned about is your low carb intake (but that's just my opinion).
