After Sunday's 'fast' of about 500 calories, I ate too much on Monday and felt bad about myself. The scale recorded an increase of 1.5 lb in one day - really depressing. So I did my second 'fast' day of the week today (Tuesday), totalling about 450 calories. I was hungry but not terribly so and it wasn't as hard to not eat as I'd expected.

After marshalling at Shipman's Knotts, I took a piece of flapjack and kept it in a bag ready for tomorrow. 'Fasting' (i.e. eating very few calories in a day) is much more achievable when I know I can eat normally tomorrow and when I can still eat two small meals during the day. Today I had cottage cheese and salad for lunch, a small apple as a snack at the fell race, some melba toast beforehand and tuna with onion, mushrooms, cabbage and courgette for dinner.

Tomorrow, though, I'm going to be careful not to over-indulge and undo all the good work. I reckon doing this for five weeks is just about possible, but will certainly be challenging.
