Blood Type: Functions Beyond Matching for Transfusions?

Researchers in England dug up the bodies of people who had died from the 1665 London plague, and made the startling discovery that most of the people who died had type B blood, and that far fewer people have type B blood now than before the plague. Scientist now must explain why people with Type B blood...

Several years ago, a very interesting new idea with regard to weight loss became all the rage: eating for your blood type. This concept answered the age-old question of why not all eating plans work for all people. That much seems undeniable – people are very different with regard to the types of food that works for them, as well as the type of exercise program. A weight loss regime that works for one person won’t necessarily work for someone else – that much we know. Some experts started to link this to blood type. There are four main blood types, and according to this way of thinking, each type represents a body type. If you eat the food that is right for your type, you will lose weight effortlessly. Conversely, most weight problems are the result of eating the food that’s wrong for your type. As well, there are types of exercise that are suitable for some types and not for others. Though mainstream science ridiculed this idea, thousands of people followed the eating plan for their blood type and many had excellent results. This is the theory: the different blood types evolved at different times in human history, and even nowadays people with those types have traits that are specific to humans at that stage of evolution. This may sound confusing, but it’s clearer with an example: According to this theory, ‘o’ type blood, because it’s the simplest type, evolved first. At that time in human history, people had not yet developed agriculture. They were primarily hunters, and ate meat and greens; they ate no wheat, and no dairy, because those foods developed later on with the advent of farming. Humans at that time in history also exercised vigorously. So, if you have ‘o’ type blood, your body is similar to this early human physiology. If you eat a lot of carbohydrates and don’t exercise vigorously, you will have weight problems and other health problems, because you are not eating and exercising in the way that is right for your blood type and body type. To lose weight and be healthy, if have ‘o’ type blood, you have to eat plenty of red meat and vegetables, and very little wheat or dairy. You should also have a strenuous physical activity, like running or weight lifting, that you practice several times a week. But if you are a type ‘a’ or ‘b’, for example, that advice would be all wrong for you. These types developed somewhat later, after agriculture was established, so these individuals can and should eat more fruits, vegetables, and grains. People with ‘ab’ type blood are lucky; their type evolved last, after humans had incorporated all types of food into their diet. So ‘ab’s can basically eat anything – within reason – and not gain weight. Over the past six or seven years, many people have followed this plan and lost a lot of weight. There are a few problems with it, though. First of all, as mentioned before, there is no hard scientific evidence that shows that people with different blood types are physiologically different. It’s an appealing idea, but it can’t be proven as yet. Also, some of the blood type diets (particularly the diet for type ‘o’) are very restrictive. In fact, the type ‘o’ diet is rather like Atkins at its most restrictive, and some nutritionists feel that this might lead to problems with high cholesterol in the long run. On the other hand, proponents of the diet argue that type ‘o’ people are precisely those who can afford to eat a lot of meat without negatively affecting their cholesterol level. If someone with a different blood type ate in this way, it might be a problem, but not for “o’s”. And it is certainly true that some people develop or don’t develop cholesterol problems seemingly regardless to their dietary intake. If the theory has no basis, though, how would we explain the weight loss that so many people have experienced? It may be simpler than you think, actually. Any one of the four blood type eating plans, if followed correctly, would have you eating healthier, more natural food. Some, like the ‘o’ diet, are also quite restrictive. It seems likely that these diets make you lose weight in and of themselves, regardless of what blood type you are!

As a high school, college, master’s and senior competitive runner, I used to often wonder why it was so difficult to lose extra weight as I grew older. Now I know why. The scientific facts I am about to share with you are only intended for runners who are trying to shed extra pounds, and who are an O blood type. I know a lot about O positive blood types because I am one.

If your blood type is A, B or AB, then what I am sharing here may be the exact opposite for you, and therefore the knowledge I share should not be implemented by you unless you are an O positive or O negative blood type, and you have first consulted with your personal physician. Believe it or not, your blood type is a more reliable measure of your identity than race, culture, or geography. It is a genetic blueprint for who you are, and a guide to how you can live most healthfully. Your blood type is older than your race and more fundamental than your ethnicity.

A single drop of blood, too small to see with the naked eye, contains the entire genetic code of a human being. The DNA blueprint is intact and replicated within us endlessly, through our blood. I was impressed to learn this fact.

More than 90% of all factors associated with your blood type are related to your primary type-O, A, B, or AB-and not whether you are positive or negative. Most of the distinctions between our blood types are found in our digestive and immune systems. Like millions of Americans and especially those who pursue competitive running at any age, I have had trouble losing the “inner tube” around my waist. Gaining excessive weight is a serious health risk, the details of which I do not need to mention here. Most overweight people know that the basic health risks are life threatening.

I am 5-foot-9 and my running weight in high school was 111 pounds and in college it was 118 pounds, the 7-pound weight gain was added muscle, not fat. My weight a few months ago was 225 pounds with at least 65 pounds of that in my abdominal area, meaning a more reasonable weight for me at 63 years old would probably be 160 pounds.

That is where I am now headed since using science to develop a lifestyle plan that will shed my excess pounds in a prudent and healthy manner. The reward for me personally is that not only will I become healthier and live longer, but I will become much more competitive as a middle distance runner in master’s and senior competitions at both the local and national level.

Any serious runner knows that you cannot compete effectively if you are carrying an extra 50 pounds. It is like strapping a 50-pound bag of dog food onto your back and trying to run a race. Runners know what I am talking about. There is a definite correlation between your weight and your cardiovascular efficiency; the less weight the better the cardiovascular efficiency.

When you have been to the top of the mountain (become a record-setting champion) you never forget, you want to remain on top, and no one ever-and I mean ever-can take away your feeling of winning and being a winner in life.

Becoming a winner again in competition offers me a lot more of an incentive to do what it takes to lose weight than just losing weight for health reasons, even though the latter can shorten my life. Most of the competitions I have been in as a senior runner (50 and older) have found me unable to drop weight quickly and effectively without injuring my physical condition and general health.

Lose Weight by Eating for Your Blood Type

If you have tried countless diets, jumping from one fad to another, without any real success, maybe it’s time to try something new. Consider trying to lose weight by eating for your blood type. It is a revolutionary new diet style that focuses on the biological needs of the body, rather than trying to fit everyone into the same dietary mold.

The idea behind the lose weight by eating for your blood type diet is that we are not all the same. Regular fad diets are aimed at the general population, but each person is different. Peter D´Adamo, the founder of this diet, discovered that different blood types need different metabolic stimulation and that certain foods can even act as poisons to certain blood types, causing health problems and obesity.

There are four basic blood types. You need to know yours before you lose weight by eating for your blood type. The types are A, B, O, and AB. These four types determine which style of diet you should be following. Peter D`Adamo outlines all the information in his book “Eat Right For Your Blood Type”, but you can also find blood type recipes online, to supplement his book.

The basic idea of lose weight by eating for your blood type is that each type of blood has its own special antigen marker. These markers react to certain foods which they consider to be “alien” or dangerous. While reacting to certain foods, the antigens cause problems within the body, similar to an allergy. According to D´Adamo, our acidity levels in the stomach as well as digestive enzymes are all influenced by blood type.

This leads to the conclusion that certain foods will sit better with certain people whose blood types allow for safe passage of these foods. To lose weight by eating for your blood type, you need to follow the dietary list. The foods on the list for your blood type will allow your body to function at its maximum potential, digesting rapidly and efficiently and helping you to lose weight.

So, how did the blood type food lists develop? Apparently, if we eat what our ancient ancestors were eating at the point that our blood type was discovered, this is the secret as to how to lose weight by eating for your blood type. A slightly far-fetched theory that many people are convinced works.

For example, since O was apparently the first blood type discovered, way back in the very beginning, these people should eat what hunter-gatherers ate. That is, a high-protein diet since the cave men basically ate meat all the time, supplemented with vegetables, root ones in particular.

Blood type A is meant to eat a vegetarian diet since when this type was discovered, our ancestors had evolved into farmers. A vegetarian diet is well-known for helping people lose weight.

The third blood type to be discovered was B, around the time of nomadic wanderings This means that Type B´s can eat a widely varied diet, with meat, fruit and vegetables of all types.

The final blood type in our lose weight by eating for your blood type list was AB. This apparently evolved far more recently and logically, means that anyone with this blood type can eat whatever A and B blood types eat!
