As opposed to a lot of random floating information, sugar does not make you fat. Sugar is just energy.

A unique property of sugar that makes it bad for you is the fact that it has a very high glycemic index, which is generally similarly proportional to its insulin index.

Insulin is the badboy.

Insulin, in essence, is the opposite of another hormone called glucagon. What do these do?

Insulin causes your body to convert blood sugar into fat and glucagon converts fat into blood sugar.

Because sugar has such a high GI, it triggers the body's release of insulin because your blood glucose levels spike because it is a carbohydrate that is broken down very quickly. When the glucose level of your body spikes, your body realizes that too much glucose in the blood is toxic so it releases insulin to regulate it.

Then, the glucose is all quickly stored as fat, and you again have a low blood sugar which will make you hungry again rather quickly.

So what that means is, as you eat sugar, you are in essence forcing your body to artificially store excess energy as fat and then inhibiting its ability to use this fat as energy when you need it. This is why sugar has an addictive persona about it because no matter how much you eat, you seem to need more and more.

Low GI foods, however, release their glucose very slowly because they are complicated carbohydrates. Your body takes longer to break them down so you avoid any sort of a spike in your blood sugar and your body uses the glucose as it is released (of course if you eat too much low GI carbohydrates as well, your body will have an abundance of glucose which will trigger the release of insulin). But even if this were to happen, you would not feel hungry very quickly which would avoid the vicious cycle sugar throws you into.

As well, the effect a high glucose level has is it makes you feel like you have a sudden abundance of energy because your blood glucose levels are so high that you feel energized to get rid of it. This is another psychologically addicting component of sugar because we get into a cycle where we constantly want that high and lose it really quickly as well, forcing us to keep eating more and more.

Once you break the cycle you won't crave sugar anymore, but it's kind of hard and you may actually go through a chemical withdrawal if you switch to low gi foods because you will perceive that you have lower energy. However, that is mainly because your body probably has high insulin levels and the energy you are consuming is still being stored as fat. As your body regulates itself on a low gi diet, your insulin levels will reduce and you will naturally feel energetic without the release of insulin, regulating your body's ability to convert fat into energy.
