A couple of weeks ago, I threw myself into cycling into work. I ended up 800kcals under maintenance for the week and putting on 1kg (well, probably not really, but that's what the scales said). Yes, I get that when I eat more, it weighs more and thus I will weigh more on balance the first week I eat lots more. So, ignoring that effect when I'm doing it this time, I still have problems around eating.
Today I cycle into work and home again. I will not be going to the gym. The cycling gives me an extra 700-800kcals or so for the day. I -should- eat at least half of those kcals, but I -think- that I actually need to eat all of them and not aim for any loss target kcals as my body doesn't deal with that very well and starts to retain water etc. I'll be cycling at least 3 times this week, so it's not mad extra work (90km in total, oh arse, and an extra 21-49km on Saturday) but I feel I need to pretty much ignore this week as it's straight after an event, so I'm a bit heavy anyway and there's lots of extra exercise which will throw my body out as well. I'll aim for "on or under maintenance kcals" each day this week, but definitely not "at or below loss kcals". Then re-assess next week when things should have settled down a bit. Of course, then I have only 1 week of normal exercise (3x weights and 2-4x cycling and 0-1 swims) before I have to taper for the final Thames Turbo Triathlon, so it may not be a fair trial or learning.
Anyone else gone through a significant increase in exercise output? How did you manage your nutrition and what effects did you see?
