What your mother told you as a child has just be confirmed as true. What you eat, and therefore your insulin levels can make you live longer.

New research on mice has found that reducing insulin in the brain extends life by 18%, which would be a whopping extra 15 years on the life of the average human.

To reduce insulin levels you need to watch what you eat, exercise and lose weight. Weight loss programs like Betalife help with this, with a particular focus on insulin levels, but you can do the same by balancing GI levels in the meals you eat and getting regular exercise.
