What is the driving force behind weight gain? Thats a no a no brainer right? Eating too many calories. Maybe. That is right I said maybe.
Eating more calories is a reason that many people gain weight. A far bigger problem may be a persons lack of activity. For example in Britain obesity rates have double since the 1980s; however, according to a paper published in the British Journal of Medicine their energy intakes have actually decreased. So they are eating less but getting fatter. How does that make sense?
Lets examine this a little deeper. The total amount of calories you burn each day can be broken down into the following components:
Activity Thermogensis consists of exercise and NEAT (non exercise activity thermogenesis). NEAT is basically burning calories from moving around. Considering the average person expends less than 100 calories per day from exercise, increasing NEAT could have a huge impact. As one of my readers I would imagine that you are burning more than 100 calories per day from exercise. If that is the case, increasing your NEAT will help turbo charge your calorie burn.
Here are some interesting notes about NEAT:
* NEAT can vary up to 2000kcal/d between people.
* Your job is a key factor in how many calories you burn each day from NEAT.
* What you choose as leisure activities significantly impacts your level of NEAT. Think about the difference between coming home and sitting on the couch vs. painting, gardening, or removing walls in the basement (how I spent my weekend).
* In studies where people are forced to overeat NEAT increases. The more it increase the less fat you gain.
* One study showed that obese subjects sat for 2.5 hours more per day than lean subjects (the lean people has similar jobs and living environments). The difference in NEAT was estimated to be 350 calories per day.
* There are compounds in our brain that may increase/decrease NEAT. Orexin is such a compound. Obese rats have been shown to be resistant to orexins NEAT-activating effects.
One of the key points to look at here is that obese individuals sit 2-3 hours more than lean individuals. If we could get those individuals to stand or move 2-3 hours more that would result in about 350 extra calories burned per day. That's about 2500 extra calories burned per week! These are not insignificant numbers! So how can YOU take 2-3 hours of sitting each day and convert that to standing or walking?
