Sean Rooney said:Hiya all, further to the advice in my Daily Commute thread I have noticed a
severe hunger since I started commuting on my bike (15 miles round trip).
7.5 miles - somewhere around half an hour (+- 5 minutes depending on
lights and weight of traffic?)
This probably means you're expending an extra 4-500 calories each way -
1000 more per day, which is a big chunk of new work when the average man
needs about 2000-2500 calories for the whole day - that's 40-50% more
effort that you need to supply fuel for!
Quoted message said:Has anyone else noted a big change in appetite when cycling this type of
difference. I'd hate to ruin all the good work of my increased activity by
stuffing myself cos I'm now more hungry.
Oh and what's a good meal to eat at lunchtime if I'm doing a 7.5 mile climb
home.
The general reckoning is to eat something within 20-30 minutes of
finishing exercise, that's when the muscles are at their most receptive
- a banana or jam sandwich is ideal: a good mix of simple and complex
carbs. This replaces quickly the stuff you've just burned - so that the
body can repair itself properly. You are indeed doing good work - but if
you don't give your body something back, it will start refusing to do
that work!
In terms of lunch, just try to eat healthily - fruit, veg and
unprocessed as much as possible, so rice or pasta or potatoes rather
than bread - and just have a little bit more, don't try to pad out the
calories with cakes and chocolate (although once or twice a week you
should - all that work demands a treat or two!).
60 minutes of exercise a day isn't so much as you need to completely
restructure your diet around it, but as you already have noticed, if
nothing else you'll be needing more fuel.
