Is it possible to burn 4000 calories a day???? I wore my h/r monitor for 15 hours yesterday and that is what it said! 600-700 were from 1 hour of mtn biking.
I don't know about all those calories it said I burned???? that was at work where I mainly sit, I do move about and go up and down stairs but for the most part I sit.

I put in all my info, age, weight, sex - surely it must be wrong?

I have been following a low cal diet my trainer told me to do with low carbs and have been tired tired tired, I have lost about 8 lbs. in almost 3 weeks but I HAVe to add in some carbs now since the weather is getting better and I can BIKE

I have been trying to stick to 1300-1500 cals a day and I stay hungry! last night I broke and ate a big bowl of green beans and quite a few walnuts after dinner! not bad but must have added up to a lot of cals - especially with the walnuts! I just want to be slim and not hungry allllll the time - and I really hate counting calories

Sorry this is kinda rambling.
