Diet Food, Lower-Calorie Aerated Foods

  • An unusual approach to dieting!
  • You may have eaten foods like Cheese Puffs or popcorn. They are delicious munchies WHICH ARE MOSTLY AIR! They take up a lot of volume, and your stomach senses that and can feel relatively full, but there is little actual weight of food in there!
  • You may have had soft-serve ice cream, which is a whipped product where ice cream is mixed with air to cause it to have greater volume. If you eat the same quantity of normal ice cream, you consume as much as double the Calories as when eating soft-serve ice cream.
  • This concept extends these air-entraining concepts to other foods, to increase the volume of the food being eaten, without also increasing the Calories in it. The premise is that if the person then eats the same volume of food in a meal (so the stomach feels full), far fewer Calories of actual food have been eaten.



Un-densified foods! A diet method may be possible that would allow eating of virtually all foods while still losing weight! A way of pre-processing food products may be possible to enable this.

There have been thousands of diets proposed during the past several decades. Each has benefited some people and been worthless to others. Here is an approach that is certain to benefit everyone that uses it!

When we eat, we generally eat foods that have tastes that we enjoy. That enjoyment is central to why we don't get bored with eating and why we sometimes tend to overeat.

There is another bit of feedback that is sent to our brains when we eat. That is related to nerve endings in our stomach, which inform us regarding whether it is full or empty.


One of the most successful approaches to dieting is to eat smaller portions, and to eat as leisurely as possible. In the same way that children are told not to eat candy or snacks just before a meal (because it ruins their appetites), a leisurely enjoyed meal allows time for those stomach nerve endings to recognize the presence of food there and to send a signal to the brain that it is not necessary to eat any more.

This works for a lot of people, but consistent overeaters have two other signals that are expected before ending a meal. First, a feeling in the stomach of not just the presence of food, but a truly full feeling, like what the rest of us experience after a huge Thanksgiving dinner. Second, is the expectation of chewing and swallowing a considerable quantity of food.

These last considerations are the inspiration for many companies offering a vast variety of low-calorie, low-fat, or other low- meals. Unfortunately, those foods often also have low-taste and high price. They are not as enjoyable to eat. I suppose this fact would keep people from overeating! Rather, people instead tend to choose foods that taste batter (but which are not low-calorie.)

Now consider popcorn. It is actually corn kernels in which the included moisture was quickly boiled, which makes the kernels explode. Everything is still there, including the taste and the nutrition, but there is now a lot of additional air inside it. When you eat a half-can of corn you are still hungry, because the VOLUME of corn you eat is limited. If, instead, you ate the same number of kernels of popcorn, you will feel very full. Much of what you ate was AIR, and you ate the same actual amount of corn, but you feel very full.

Un-Densified Foods

This is the central idea of this new Diet Food invention. Nearly any food could be put in a small chamber, which is suddenly evacuated of air. This situation would make the piece of food suddenly expand in size. When regular atmospheric pressure air is re-introduced to the chamber, it fills in the new voids in the piece of food. I call it Un-densified food. Let's say that the resultant volume was twice what it started out at. In that case, the original amount of food and nutrition and flavor will be present. An equal amount of air is now present. This makes it so twice as much chewing and swallowing is necessary to eat the same amount of food. The psychological fulfillments are accomplished (a sufficient amount of chewing and swallowing and the feeling of a full stomach). All of the expected flavors are still present. Those flavors are slightly diluted by the presence of the additional air, but a little extra chewing and savoring will make up for that.

Full flavor, full psychological fulfillment of eating, less actual food, almost infinite diversity of food types. A perfect diet!


Expanding various kinds of foods might require different methods. For example, a dense apple will tend to shatter by the method described above. For such a food, a slower depressurization may work better. Other foods might be expandable by air injection needles or other air injection methods.

Fortunately, the foods that seem to be most resistant to such expansion, such as fruits and nuts, are some of the healthiest and most nutritious foods available, so maybe they do not need to be expanded.

Addressing heavily advertised Weight-Loss and Diet Programs

IF you take in more Calories (actually kilo-calories or Kcal) in a day than you use up, the excess energy is turned into sugars and fats, and eventually into fats called lipids or triglycerides, to be stored away for a possible future survival need, and you will gain weight. Equally, if you use up more Calories in a day than you take in, some of those existing lipids or triglycerides, fat and sugars is converted back into forms that can become energy, and some of the bodyfat are therefore converted into that work and weight is lost. The premise behind "working out" is closely related to this fact, and it would work to some extent, if it were not that all that exercise often creates a healthy appetite!

It is interesting that enormous numbers of TV, radio, newspaper and magazine ads talk about amazingly fast rates of weight loss, with some diet or some piece of exersize equipment! We tend to consume around 2200 Calories of food energy and use up roughly the same amount each day. It is rare when the difference, either way, is greater than around 200 Calories in a day. It also turns out that the sorts of exercises usually done at Health Clubs in working out, tend to rarely even double our normal body energy consumption of about 100 Calories per hour (thereby burning off only another 100 Calories per full hour of such exercise, again rarely more than 200 [extra] Calories burned off in such an extended workout session).

We note that bodyfat is a very compact source of energy supply (the whole point of it regarding survival!) and a pound of bodyfat contains around 3500 Calories of chemical energy stored in it. This indicates that two or three weeks are often likely necessary (3500 / 200 or about 18 days) to be able to lose even ONE pound of bodyfat! People who try to lose weight by dieting and/or exercise get frustrated at such slow progress! (For success, they must have immense patience and incredible dedication to the effort, both of which seem opposite of modern hurry-up and have-it-now attitudes!)

So TV and magazine and newspaper and billboard ads brag about losing 50 pounds in 50 days or something like that. Think about that. In order to lose 50 pounds of bodyfat in 50 days, it is necessary to lose or use up more than 1 pound every day. And such ads and concepts rarely also even attempt to get the person to also reduce the excess amounts of food they eat which caused them to become obese in the first place! If such a program could succeed, it would mean using up around an EXTRA 5000 Calories of energy from stored bodyfat each and every day. Even if the person did not eating anything at all for 50 days, the body's metabolism could only use up around 2200 Calories each day, where the actual total body weight loss would then be around 30 pounds in those 50 days! (Our bodies have an amazing ability to survive for many days when no food is available!) (By the way, people who go on long religious Fasts tend to lose MORE than this amount of total body weight, but that total loss also includes a large amount of WATER that is also lost in the process.) There is no easy way for our bodies to use up 5000 Calories per day! Do you see why such claims are exaggerations and/or misleading?

There is another way to look at all such claims. People selling such thihgs claim to make bodyfat "melt away" or equivalent, right? Bodyfats are all lipid or triglyceride molecules that are nearly completely carbon, hydrogen and oxygen atoms in complex combinations. You probably know of a basic law of science that says that nothing can either be created or destroyed (Conservation of Mass). Well, those lipids or triglycerides are commonly around 40% carbon. So WHERE does the carbon go? It can't just disappear! It must go somewhere! Can it VANISH in body heat? No, that would not account for the carbon atoms. Could it get excreted? No, because the digestive system is entirely separate from the body metabolic processes. You can rule out EVERYTHING, except for one thing! Your exhaled breath! Virtually the ONLY way that a human body can get rid of carbon atoms is to oxidized them into becoming carbon dioxide molecules, and then send them out of your body as exhaled air! Sadly, bodyfat can therefore never just "melt away"!

So, IF someone claims to cause bodyfat to be used up three times or ten times as fast as natural, they HAVE TO explain how THREE TIMES (or ten times) AS MUCH EXHALED BREATH had to also occur in order to carry the carbon atoms from all those bodyfat lipid or triglycerides molecules away from the body! Otherwise, all those carbon atoms have no easy way of going away!

There ARE a few very minor chemicals that get created which use up carbon atoms, but most of those stay in the body to be used for other purposes, and so they cannot represent actual REDUCTION of CARBON in the body! Those processes also affect VERY small amounts of the carbon, not enough to seriously even need to think about when considering amounts of bodyfat!

By the way, you might see the connection here between when you do serious exercise and then have to breathe heavily for a while? In doing strenuous exercise, you DO use up some bodyfat molecules (but a disappointingly small amount of them. We will shortly see in the Technical paragraph below that even when we exercise hard enough where our breath is TWICE normal, that only removes the carbon from around 1/1100 pound of bodyfat per minute. A full hour of such strenuous exercise and we can remove only around 1/20 pound of bodyfat!). Due to the requirements of the exercise, the body naturally accesses some of your energy supplies, first, the sugars, which are most easily accessed fast, but then the bodyfat stores. As those (sugar or) lipid or triglyceride molecules are oxidized, carbon dioxide molecules are formed, which get carried to the lungs and then exhaled with the next outgoing breath. If you do TWICE as much exertion, then twice as much of the lipid or triglyceride (bodyfat) molecules get oxidized, and twice as much exhaled breath is needed to carry all that carbon away from the body! Now you know! (You also breathe more heavily to get more oxygen INTO the body, to be able to do all that oxidization of all that carbon into carbon dioxide. The body has an immense number of unique chemical reactions, and we have greatly simplified the matter here!)

This brief discussion is intended to show you that virtually ALL the carbon that can leave your body must leave by your exhaled breath, and that all the impressive claims of flashy advertising which claim otherwise are simply not credible. IF some program causes you to BREATHE MORE HEAVILY, either deeper breathing or faster breathing or both, THAT WILL directly increase your body's ability to get rid of undesired bodyfat. So the next time you see any of those ads on TV or elsewhere, THINK about whether they are describing any credible way where your breathing is increased. If not, there is no realistic reason to spend money to buy what they are promoting!

On a more technical level, each INCOMING breath draws in air which is at the natural 0.038% of carbon dioxide, and each outgoing breath contains around a maximum of 4.4% of carbon dioxide. When sitting, we breathe around 12 times per minute and each normal breath is around 0.5 liter of air. This all means that in each minute of normal breathing, we exhale around 0.25 liter of carbon dioxide. This means that each minute, we each exhale around 0.5 gram of carbon dioxide, or around 1/1000 of a pound. (In an entire year of normal breathing, we each exhale around 500 pounds of carbon dioxide!) This includes around 1/3500 pound of actual carbon atoms per minute. If they had come from normal foods (averaging 40% carbon atoms), that represents around 1/1400 pound of food which would disappear during that minute (of normal breathing). At around 2200 Calories per pound of average normal food, that means that around 1.6 Calories of food (or other energy sources) gets used up every minute.

If the carbon atoms had come from lipid or triglycerides bodyfat molecules instead, a far more concentrated source of stored energy, only around 1/2200 pound of bodyfat would need to get used up during that minute (of normal breathing). This situation would occur if the person went on a fast without eating any food, or if the person exerted himself more than could be supported by the food recently eaten. At 3500 Calories per pound of bodyfat, that again means that around 1.6 Calories of bodyfat would get used up every minute. Since a day includes 1440 minutes, that again would account for the 2,200 Calories of energy that our metabolism needs to use up every day to keep us alive. This then proves that each minute of regular breathing involves exhaling the carbon atoms from the equivalent of either 1/1400 pound of average food or 1/2200 pound of bodyfat. That is essentially the ONLY significant process the body has of removing carbon from itself, which it does in order to supply energy for its many processes!
