Environment and genetics influence our weight.
“The changes in the environment came in the last 40 years, but we’re still stuck with the genes that worked 2,000 or 3,000 years ago.”
Obesity gene (FTO gene) works as a master switch for fat storage.It tells your body when to store extra calories as brown fat rather than white fat.
Obesity researchers believe that people who become obese have a variance of the FTO gene.This variant gene tells their body to store calories as white fat so they don’t burn extra calories as efficiently as someone whose FTO gene works differently. “If they eat an extra cookie, it may end up on their hips whereas a person who stores more calories as brown fat can eat that same cookie and burn it off easily.
Even for people who have the right variance of this obesity-fighting gene, the human body tends to work against us when trying to lose weight. We can blame this annoying reality on the region of the brain called the hypothalamus, which controls weight management.
The hypothalamus “sets” a certain minimum weight for our bodies, and will fight like hell to keep us from dipping below that weight.Unfortunately, however, it doesn’t prevent us from gaining weight—because, well, there might be a famine later!
Making matters worse, if we keep weight on for a long period of time, the body will reset its “weight set point” and work to maintain the new minimum weight. The moment you start trying to shed those pounds, your body kicks into famine mode.The body releases hormones to make you feel more hungry and less full in an effort to keep the weight on.
