The relationship between Leptin and weight management.
We consume an average of 1 million calories per year. What is amazing is we have a 99.6% accuracy balancing energy in (food) and energy out (exercise, living). The bad news is the more we train the more we eat. After 2 years 70% to 95% of people studied return to their starting weight.
We use a fat regulating system involving the hormone Leptin. Leptin is released by fat cells and has been shown to decrease apatite. So.. the more fat we have the less we want to eat? unfortunately its not so simple. It looks like Leptin insensitivity has a greater effect on weight gain. Research is limited around this topic but it looks like genes, lifestyle factors and diet could effect the bodies sensitivity to leptin. Our bodies could be fooled into gaining body fat to increase leptin levels.
The bottom line is..at this point in time your genes are mapped out, how you choose to deal with them is up to you.Personally I love been fit and fairly healthy. So concentrate on your health; exercise regularly, eat healthy and enjoy life.
Remember one pint is equal to 40mins of brisk walking so space your pubs apart. ;-)
