You see, if I go swimming for 30 minutes, I'd log that down as 100 cals burnt

But these things will take weight, height and the exercise into account, and will say I burnt 400kcals

Then I'll put in that I biked 2 miles home, and that will say it's 100kcals a mile or something like that

I find all this very misleading. In my opinion thelike you implied, a guide, and not an excuse to biking and swimming comes to about 250-300kcals tops, not 600

I just wonder if some below who've said they've got a bit fatter cos of these things, is because the science is a bit off
