Sugar makes you overeat

PAncake stack (blog)

If you have been following this blog for a while you probably already know that fructose isn’t good. New research presented yesterday at the annual meeting of the American College of Neuropsychopharmacology shows that all sugar isn’t all the same when it comes to hunger and feeling full. This research investigated the differences between fructose and glucose by showing images of food to volunteers whilst they were having a fMRI scan of their brain.

The results indicated that*:

  • Eating or drinking fructose triggers the reward circuits in your brain and makes you want to eat when you see something desirable (such as cake), even if it’s just an ad on TV or a picture (I’m sure marketeers are aware of this, perhaps without understanding the reasons!).
  • Fructose does not make you feel very full.
  • Glucose, on the other hand, makes you feel more sated and hence you don’t feel like overeating.

So, what does this mean for you?

This makes all the difference in the world if you want to loose weight or just be healthy. Be aware, however, that most table sugar and sugar added to processed foods are made up of a combination of fructose and glucose. Choose your sugars wisely. If you cook and bake, swap fructose for glucose. Glucose is the body’s primary source of energy and the sole energy source for the brain.

This doesn’t mean that you should start overindulging in glucose Don’t eat more than you normally would  of fructose rich foods. But, if you want a healthy life style, you can start by swapping sugars, then slowly reduce your intake and you will notice that your taste-buds all of a sudden become less sweet. You then don’t want to eat as many sweet things and if you carry on, eventually you don’t want sweet things at all. No willpower needed to resist the sweets, just your cleansed body telling you what you need.

You can also use alternative sweeteners (non-sugars). If you want to know more, please follow my blog.
