Hi – I have just started the 5:2. i am a 67 year old male and live in the South of France. My issue is that I do a lot of cycling (like 3 or 4 hours at a time, 4 days a week – and in the French Alps so it is very hilly). I have lost 3 1/2 kilos in a week, so I am happy with that but I have no energy. My cycling has gone to pot and on my fast days I feel so shaky I cannot even contemplate cycling – or any exercise for that matter. But the book says you burn more fat if you exercise on fast days.
So I am not sure what to do, and whether it is a good idea to force myself to exercise on a fast day. I feel as if I would faint if I went out on the bike on a fast day.
Anybody have any views ?
