I'm starting out with intermittant fasting 2/5 and have been rummaging around the Internet looking for information. Prompted because I saw the Horizon documentary and thought it very interesting.

A few basics about me:- age 45, height 5'4" weight, 59 kg (sorry to mix metric with imperial but I live in France and my scales don't do llbs), I've lost 2 kgs so far. I have three children and last year ran regularly including a semi marathon and several other races. After a nasty injury this February (fractured femur) I was forced to take a break from running which was horrible. This last month I've been getting back on track but not so regular as before.

I'm hoping to lose another 5 kg - it would benefit my running - also I'd look better :-)

Any advice on what to eat on fast days? (I have between 4-500 calories).

Thanks everyone
