but they were probably a foot and a half, just short of white-capping. i went to blue heron park, and while the bay was relatively sheltered, out in the strait there was a bit of a wind, which, together with the incoming tide, produced some nice waves. which were great fun to paddle in; i'd power on out towards a tiny islet, and then "surf" back in with the waves at my back. an hour and a half didn't even seem that long.
i'm coming to the conclusion that cardio-focussed exercise for weight loss is something of a bogus proposition. not that i am kayaking for weight loss (or doing anything for weight loss), i'm just keeping a log of food intake for heart reasons right now, and making some observations. kayaking for an hour and half at the activity level i am doing it burns off about 500 kcal. walking every day for 40 min at ~3mph burns off 250 kcal. changing my diet to one with a lower glycemic load has reduced my caloric intake by ever so much more. i couldn't possibly exercise at the level at which, for example, cutting out most refined sugar affects me, and now i seriously doubt anyone can but those who are already very fit.
weirdly enough, this makes me feel good. *heh*. for most of my life i've been reasonably active -- not athletically, but i've steadily walked, hiked, swum, canoed, with only some excessively sedentary periods. and people used to think of me as a couch potato, because i've always been overweight. i sorta chafed at that. ok, i wasn't fast, or particularly strong, but i had decent endurance, and i did most definitely not lounge on my couch all day long (more likely in my computer chair anyway). i've been equally fat when i was reasonably active as when i hibernated in front of my computer all winter long. i've been in very different shape, however. so yeah, going for "health at any size" is the only message that makes sense to me after observing myself and my interactions with food and exercise for decades.
i've mostly opted out from reading size/fat shaming anything (easy to do only if one no longer watches mainstream tv or reads mainstream papers/magazines). and i no longer see dr. weightloss-uber-alles ("i don't understand why your cholesterol levels are so good"). i've got my blood pressure and blood sugar levels down with diet changes, not with increasing exercise past a daily walk. but i still carry some of those dumb messages with me, and it's good to see it confirmed that they ARE dumb.
