Scientists have discovered that when a person becomes overweight or obese, the system in your brain designed to regulate appetite doesn’t work anymore. When your body has enough food, it secretes a substance called leptin, which inhibits appetite. However, studies have revealed that when you have too much body fat and too much leptin, the brain becomes insensitive to this feedback mechanism. The result is that hunger is not diminished when it should be and increased food intake results.
The great news about this discovery is you can actually turn the leptin mechanism back on by restricting food intake and exercising. Gradually over time, your body’s brain cells will again become sensitive to leptin if the leptin stimulus (fat cells) is decreased, giving those brain cells an opportunity to switch back on.
Choosing a portion controlled, low glycemic eating pattern, along with an increased activity level, will not only allow the gradual reduction of this block in inhibition, but will decrease high insulin levels, which are also known to be appetite stimulants. These small choices, taken each morning and followed throughout the day, will lead to appetite suppressionand a more healthy and more normal eating patter.
