So. This calorie monitoring/restriction only makes sense when I keep an eye on what I'm eating each day; and I guess it doesn't hurt anyway to be aware of food input.

Today:
Cereal/Milk - 288 kcal
Protein Shake - 265
2 Apples - 140
1/2 melon - 110
Ground Chicken Patties - 200
Salad - 77
1 piece of cake - 205
Protein Bar - 137 
Energy Drink - 150

Total: 1672 kcal

That's not much (surprisingly little, in fact), but not exceedingly less than usual, I think. Maybe a bit. OK, maybe 1.000 kcal less than usual. Anyway, I ate pretty well on the weekend, so I might still be feeling full from that.

I'll try to balance in at around 2.000 kcal per day; with Wednesday being the Eat-what-you-want cheat day, and Thursday being the fast day. I'll see whether I can do climbing on Thu or not. That's the plan, anyway, which I'll try to stick to for at least six weeks.
