Can’t say that 400kcal worth of beer would be my choice of nutrition on a fastday. Beer is pretty much exclusively carbohydrate too, so I bet it’s a battle of wills to stop yourself having more or going on to other food. And then there’s the ‘carb effect’ the next day too.

Whenever I overdo it (especially on carbs) the night before a fastday I find it more difficult to ignore ‘hunger pangs’ and get through a fastday with no problems. If I eat normally the day before I don’t have any hunger twinges at all. So my question would be, is the 2 beers thing necessary? And is it just on fastdays or do you do this every day? If it’s every day I’d recommend that you drop it straight away for fastdays and replace it with something more nutritious (or nothing at all). Dropping your alcohol intake twice a week shouldn’t be too much of a hardship and I really think it might help you if your main aim is weight loss (don’t ‘make up’ for those 2 days on your other 5 though). Once you get into that, maybe you could consider helping yourself out on fastdays by reducing beery carb intake on the night before fasts too.
