I would hazard a guess that sleeping is a form of fasting. Thats no food for 8 hours (or in my case 6 hours). Prolonging the fast (i.e. not eating breakfast) on a fast day, should lead to fat stores being tapped into earlier in the day. If you do some light cardio in the morning. This should accelerate fat loss. (I’m following the logic of the other forum members). I have tried this regimen one week (Ive got a back injury at the moment so have laid off the excericse) and have to say that I did not get exhausted (light headed at about 15:30, but that passed). Looking forward to resuming this.

I’ve also seen other blogs where people have eaten one large meal per day (I’d say this was another fasting varient). Ultimately, each person has to choose the regimen that works for them.
