How to use Science to Lose Weight #1

The human body is the most complex chemical reactor in existence. Ultimately, the amount of fat on your body is the result of multiple factors, many of which are poorly understood in the marketplace.

The purpose of this series of posts is to explain what those factors are, so you can make informed lifestyle decisions decisions when choosing how and when you exercise, and what type of food you eat

This has been a particular issue for me for many years now, as I am one of the small number of men to have suffered from an eating disorder. Eating disorders are almost exclusively the domain of women (97%). I am one of the 3%.

If you are reading this article to quickly get to the bottom line (as I often do) I will very quickly summarise the conclusions I have come to, and the rest of this article and the ones that follow it will explain the logic behind those conclusions

In summary:

1. The concept of calories in, calories out is wrong. The number of calories a food contains doesn’t mean much,

2. The glycaemic index of a food is everything.

3. When looking at a food label the amount of sugar a food contains is far more important than the amount of fat it contains.

4. When selecting foods based upon the type of fat they contain, where possible consume monounsaturated fats.

The first issue to is how the body gets its energy to operate. In other words, where does the body get its fuel? Your car gets its energy from either petrol or diesel – what is the fuel that your body runs on?

The answer is that it is mostly glycogen (a form of glucose). I say “mostly” because under some circumstances the body has the ability to switch to different fuels, but for the purpose of this discussion we can stick with glucose as the main source of fuel.

In simple terms there are two main of glucose – carbohydrates and fat in extreme circumstances muscle tissue can be broken down to provide glucose, but this is not the normal mechanism of operation.
In my next post we’ll consider this fuel system in more detail, and start to understand how we can manage it to control our waistlines.
