For many of us who are into a weight loss program, we see to it that we follow the most dependable information on how to achieve natural fat loss.

But to understand weight loss, I had to learn first how fat loss truly works inside the body.

Now the information that I am about to give you is quite intriguing and is not likely found in most health books, newspapers, and weight loss journals, or even in some diet books.

Plus, having a personal fitness coach or dietician won’t help much either as they are likely unclear on this matter.

I will try to give the most accurate information that is based on scientific studies on how fat loss truly works inside our bodies.

How our Body Regulates Body Fat

So how exactly the body fat stores are regulated, and the fat that’s burned up for energy?

As we on a diet, most likely we follow a few meals and snacks. Let’s say a cereal or wheat bread in the morning, a sandwich at lunch time, and in dinner with some pasta, rice or some bread.

In-between meals we get to have muffin, some fruit such as banana, or some cappuccino or brewed coffee from local Starbucks.

All of these foods contain carbohydrate. As all of us dieters know, foods can be made up of protein, fat and carbohydrate. Different foods mean different amounts for each.

For example, meat is all protein and fat while bread largely contains carbohydrate and some protein.

As carbohydrates are eaten, it gets digested and converted into a form of sugar in your bloodstream. This sugar is called glucose.

Glucose is then used by our body to produce energy.

The Role of Glucose

It is important that the level of glucose in our blood needs to be balanced quite delicately between certain ranges. Too much or too little glucose levels can mean disaster to our health, even deadly.

To achieve healthy levels of glucose constantly, our body uses a clever process of storing away any excess glucose when we have too much of it.

This is done by sending enough insulin around the blood, which tells fat cells and muscle cells that they should absorb more glucose from the blood.

The body continues this process until it reaches the safe amount of glucose.

This means that glucose is absorbed by our muscle cells or stored immediately for later use. Glucose is also used by fat cells with fatty acids and is also stored for future use.

In contrast, muscles have limits on how much they can store glucose. So excess glucose will directly go to fat cells once this limit is reached.

If we don’t eat in a few hours, then this means that we don’t have enough or no insulin in our blood and the fat cells is free to release this stored energy back into the bloodstream for us to use.

This scenario can happen only when there’s no insulin present in our system.

So What is the Point?

The logic is that, if there is insulin in our system, it means that we have too much glucose in our blood and therefore our fat cells shouldn’t release any more.

So if there’s no insulin present in our body, fat cells can freely release the energy into our bloodstream for us to use.

Now, if we take another meal or snack with some carbohydrates in it, then it adds up to more insulin to be released, this helps our body to re-balance our blood sugar levels again.

For most people, this process happens multiple times in a day. This is one of the reasons why certain diet plans such as Zone Diet, require people to eat 5 to 6 meals a day to ensure that their blood sugar levels are at normal range.

But that didn’t actually answered why we actually gain fat and how we can burn it up again.

Over years of this eating process and releasing insulin, our muscle cells and fat cells tends to ignore the insulin’s main role. So the bigger we eat, the bigger the effects.

When this “tolerance” occurs, our body will have no choice but to release more insulin to ensure that both of our fat and muscle cells do what they need to do.

Therefore, the period of time when insulin is not present tends to get shorter, or in fact it may be the only time the insulin is present is during overnight, depending on our eating patterns.

While we sleep, after we digested the last portion of our food, there is most likely a period of time when we are using our own fat for energy. This is possible because there is no insulin in our bloodstream.

What about our Muscle Cells?

Well, they also use glucose for energy. The main key however is that, the muscle cells are surprisingly efficient and for many people, the muscle cells may be full of energy that doesn’t get completely used up all day long.

That means that we don’t need a lot of extra energy to stay full. If we workout, and so our muscles are emptied of this stored energy. But, there is a lot of energy that needs to be replaced.

This is actually a healthy situation for our body because we are storing more glucose in our muscles rather than in our fat cells.


With insulin playing a big role in fat storage and fat burning, it is just plain sense that the white loss method and the one that continues to work into the future needs to work to reduce the amount of insulin our body sends around the bloodstream.

This makes our body to burn our own fat for energy and also preventing to store any more energy as fat.
