You started off with the problem
How many miles did you walk, jog, run or ride a bicycle that day ?
I'd actually been hiking at two national monuments!
The day before, I'd completed several hikes inside Canyon De Chelly, (around 5 miles up and down canyons in 35 degree heat) and the day I stopped off in Gallup, I did several trails at Chaco Canyon.... (probably around 8 miles again in sweltering heat)
Samething where I am from in the UK, every corner there is a Dixie Chicken, Fried Chicken dot com, Super Duper Fried Chicken but we 3 big parks, super markets, mini markets and a 24 hour gym.
There are alternatives so no excuse for people in that area to get fat but many are including school children.
Lack of education and right out laziness.
You don't seem to understand the problem, laziness is absolutely not the root cause of the problem here.
Yes, we all know some big fat guy who weighs 35 stone, eats 8000 cal of junk a day and doesn't care and will be dead in 5 years, we all know someone like that - but he isn't the problem at all.
Children are the problem, because obesity in children in skyrocketing - if you're obese as a child you're 70-80% more likely to stay obese throughout life.
You can't sit in an environment which does the following things with impunity;
- Junk food advertising aggressively targeted directly at children
- Junk food engineered to defeat the bodies natural satiety mechanisms (you can't stop eating it)
- Junk food that's actually designed with sweetness levels to suit the palette of a 5 year old
- Junk food that's designed to cause addiction (combining high levels of fat and carbohydrates at the same time)
- 70-80% of food in the supermarket exists for nothing other than pleasure with practically no nutritional benefit
- Saturation levels of junk food in towns and cities - delivered right to your door
- Shops where you're literally herded through a maze of sweets and snacks before you can get to the checkouts
The food industry is the root cause of the problem, in the same way that the tobacco industry is the root cause of almost all lung cancer.
Fix the food industry - you fix the obesity, there is absolutely no other way.
