How to eat more and still lose weight?

We all know that Food plays a major role in all the weight we gain. Yet we can’t avoid food. Why?

We need food for survival. Food gives us energy and provides vitamins to our immune systems. Without food we are dead.
But, if we learn more about it, we may find a way to enjoy it while losing weight.

One thing we all know is that when we eat food, it is digested and absorbed by our body.
And by understanding digestion and absorption process, we might be able to find a solution to our weight problem. Who knows?

We might even find a way to eat more food and lose more weight and never gain a pound. Sounds interesting. Doesn’t it? Read on.

The process of digestion and absorption start right from the point where you put your food in your mouth.
The gastrointestinal tract (GI tract) is the site of nutrient digestion and later of absorption. This is a long hollow tube that stretches from mouth to the anus. Food carries many important nutrients and these nutrients must be absorbed by the walls of this tube as the food makes its long journey.

During this journey, lots of chemical substances like enzymes, acids, bicarbonates, etc are secreted by the GI tract. And this promotes the breakdown of the food until it reaches the end of the journey where the GI tract eliminates wastes.

And this whole process requires energy to be spent. I repeat – “This Whole Process Requires Energy To Be Spent”.
It is this energy that we are interested in. The more energy you spend the fewer chances of you gaining weight. In fact, if this process spends more energy than that of the energy carried by the food itself, guess what – you will lose weight. This is what ‘The Negative Calorie Diet’ is based on.

Before we go off track lets look at the process of digestion and absorption.

When you put food in your mouth, what’s the first thing that happens? A sudden rush of Saliva. This saliva contains mucus and certain enzymes. The enzymes are used to breakdown large carbohydrates into small units. And mucus is used as lubrication between the food and GI tract, especially esophagus.

Your mouth and stomach are connected by a tube called esophagus. The food you swallow goes down the esophagus to your stomach. Only proteins are digested in the stomach and some of the alcohol is absorbed here. Your stomach secretes acid and some enzymes that churn into food. These acids and enzymes help digest protein and this gets absorbed through the walls of your stomach. In 2 to 4 hours your stomach will slowly release small amounts of food into your small intestine. Liquids are the first to leave the stomach, followed by solids. And a fat meal is a slow mover. It is slower than a carbohydrate or protein meal.

Next comes the major player in the process of digestion and absorption. The small intestine.
The small intestine is about 10 feet long and 1 inch in diameter. As the food enters the small intestine, pancreas releases bicarbonate to neutralize the acids released the stomach. Most nutrient absorption, about 95%, occurs during this journey in the form of protein, carbohydrate, fat, and alcohol. Dietary fiber is not digested in the stomach or small intestine. Small intestine uses the enzymes made by the intestinal cells and pancreas to absorb the nutrients from the food. Muscular contractions constantly mix the food and this exposes more food surface to enzyme action. Most of the energy expended in digestion and absorption is spent here in the small intestine. And the amount of energy expended depends upon the nutrients in the food. For example, no or very little energy is expended in absorbing fat nutrients. Whereas a lot of energy is expended in absorbing starches. This is the root for the negative calorie diet.

Food stays in the small intestine for 3 to 10 hours before it moves on to the large intestine.

Little of the original foodstuff, about 5%, still remains undigested when it enters large intestine.
The large intestine is about 3 1/2 feet long. Most of the dietary fibers are digested by the bacteria that is in here. Much of the remaining water and undigested starches are absorbed here. The food remnants and wastes stay here for about 24 to 72 hours before being flushed out.

The whole process takes 24 to 85 hours. As you have seen there is a lot of work involved in this process. No wonder they call the human body – an amazing machine. In order to do this much of work, your body spends some energy. On average 10% of the calories you eat is spent in this process. But this amount of energy spent is dependent upon the type of food. Fat foods like fries and simple sugars like soda require a minimal amount of energy to be spent for their digestion. But certain other starches require more energy. These type of foods include celery, carrot, cabbage, cucumber, lettuce, apple, honeydew, pineapple, grapefruit, and many more.
The negative calorie diet lists over 100 types of foods that require more energy, than they supply, to digest and absorb.
Simply put – when you eat these foods, “they burn more calories than they supply”.

Now you know the result of burning more calories than you eat. Right?
Yes. That’s right. You will lose weight when you burn more calories than you eat.
