There are three simple family-oriented rules of thumb to overcome childhood obesity.

They basically involve limit setting to address the brain's "get more" drive strengthened through habitual over-consumption of temptations including highly caloric processed food, hyper-reality media and electronics, as well as excessive sitting. His 3 "rules" of living promote physical and mental health for children and parents for both treatment and prevention. 

They are below, though the official - and slightly weirder - terms for them are farther down:

1) Limit highly caloric processed food
2) Limit media and electronics
3) Sit a lot less

Kristopher Kaliebe, MD, Clinical Assistant Professor of Psychiatry at
Louisiana State University Health Sciences Center, says this limit setting addresses the brain's "get more" drive habitual over-consumption of temptations.

 The official descriptions are: 

1. Eat Food – Not too Much, Mostly Plants. Dr. Kaliebe explains that eating natural, unprocessed, raw food eliminates the constant need to calculate calories, carbohydrates, fat, protein, vitamins, etc. – a reason diets fail. This rule also advises severely restricting foods like chips, sodas and fast food.

2. Get Up and Move. Noting that humans are not built to sit for much of the day, Dr. Kaliebe says children as well as parents need to find excuses to move whenever possible and be especially active during leisure time.

3. Honor Silence. Dr. Kaliebe says sensory overload and "noise" from popular culture, gaming, advertising, media and electronics crowds out important things such as family matters, academics, sleep, and the development of other interests.
"Habits have profound effects," concludes Dr. Kaliebe. "Celebrations, such as birthday parties, are less meaningful. Don't stress over the occasional special treat, but be strict about everyday routines."
