akaAndrew said:Well yes, and sometimes the obvious needs to be stated. You read posts on this very forum asking 'which after ride meal for weight loss?' etc. Perhaps some think exercise burns way more calories than it actually does.
The articles only mentioned increased hunger as a part of it though. It wasn't the sole thrust. They also mention that, for those looking to loose weight, diet is where you look first. Lifestyle changes too, look to being generally active - as you mention.
This is the kind of argument that I find interesting... near compelling in fact. In the subsistence environment that we lived in, any creature that expended huge amounts of energy during intense exercise (fleeing, for instance) would have to restock that energy. This could prove difficult. Any creature that burned less energy would be at a distinct advantage. Evolution would suggest that such a creature would be the long term survivor.
We no longer live in that kind of environment, so perhaps the biggest factor in our weight gain is the ease of access to refueling... i.e. over indulgence.
Our ancestors would have a celebratory feast following a major kill. To achieve the kill, the menfolk would run for several dozen miles across the plains chasing a speared antelope ( for instance ).
The celebratory feast lingers as it is customary to stuff your face at parties, weddings, retirements, birthdays, anniversaries, Christenings et al.
I was at an engagement party last night where there was LOTS of food, and some very LARGE people stuffing their faces.
I had enough discipline to abstain over-eating.
