We started having a conversation in another post about 'weight" and seem like this is a subject that everyone has on the back of their minds.

After doing some research I came across this info that makes some sense to me but at the same time they look like huge numbers..

Sex: Male

Height: 5'10''

Weight: 223 Lbs

Age: 34

Activity Level: Very Active.

Calories needed to maintain this weight: 3581...(?) Really? Sounds like a lot..!

the link to this site is this one if you want to try yourself: http://walking.about.com/cs/calories/l/blcalcalc.htm

So to maintain I have to eat 3581 calories a day and to start loosing weight "they" recommend to eat 500 less that the result number we have.. To me this doesn't sound too bad.. What do you think?

The other number that I can't totally understand is the burnt calories, my main activities are cycling and walking. I ride some 200+ km a week and walk around 25 km every week (between work and other activities, not as a sport)

To give you an example: Strava (yes I use this to track my cycling) tells me that I burnt 1304 calories in yesterday ride and the site I am using to track my calories (eaten) tells me that in the same ride I burnt 2600.. That is a lot of difference..

So what I am looking for here is your opinion and personal experiences with this subjects in order to reach my goal and not to make the same mistakes other did and to follow the ones that had good results for others.

Thanks everyone and feel free to add or take any info that you consider useful.
