One size fits all is probably one of the biggest lies of today. It doesn't work for shoes, clothing, medical treatment, and that goes for diets as well.
The human body comes in many shapes, colors, and blood types, so to think that there is one diet to rule them all is nieve at best. There are many diets trending nowadays all claiming to be the one that is most suited for perfect health and that may be true for the person recommending it, but not necessarily is it perfect for the person they are recommending it to. For instance, a vegan diet may be what a person suffering from diabetes may need for their body to heal, but a person with cancer may need a ketogenetic diet. One may feel amazing going Paleo, while another has greater success with intermittent fasting. Each person needs to take into account their health issues, their blood type, and their own personal experience because just as there are no two snowflakes exactly the same, there are also no two people exactly the same.
So for those who have a little personal experience to go on, what diets go best with specific health issues and blood types?
Peter J. D'Adamo, N.D., in his book Eat Right 4 Your Type, explains:
"There had to be a reason why there were so many paradoxes in dietary studies and disease survival," why some people lose weight and others do not on the same diet or why some people keep their vitality as they age, and others do not, says Dr. D'Adamo.
Type O - People with type O blood fare best on intense physical exercise and animal proteins and less well on dairy products and grains, says Dr. D'Adamo. The leading reason for weight gain among Type O's is the gluten found in wheat products and, to a lesser extent, lentils, corn, kidney beans, and cabbage, Dr. D'Adamo explains. Ideal exercises for Type O's include aerobics, martial arts, contact sports and running.
Type A - Those with blood type A, however, are more naturally suited to a vegetarian diet and foods that are fresh, pure, and organic. As Type A's are predisposed to heart disease, cancer, and diabetes, "I can't emphasize how critical this dietary adjustment can be to the sensitive immune system of Type A," says Dr. D'Adamo. Type A's can derive significant benefit from calming, centering exercise, such as yoga and tai chi.
Type B - Type B's have a robust immune system and a tolerant digestive system and tend to resist many of the severe chronic degenerative illnesses, or at least survive them better than the other blood types. Type B's do best with moderate physical exercise requiring mental balance, such as hiking, cycling, tennis, and swimming.
Type AB - Blood type AB, the most recent, in terms of evolution, of the four groups and an amalgam of types A and B, is the most biologically complex. For this group, a combination of the exercises for types A and B works best, says Dr. D'Adamo.
Blood type, with its digestive and immune specificity, is a window on a person's probable susceptibility to or power over disease, according to Dr. D'Adamo. For example, Type O's are the most likely to suffer from asthma, hay fever, and other allergies, while Type B's have a high allergy threshold, and will react allergically only if they eat the wrong foods. Type B's are also especially susceptible to autoimmune disorders, such as chronic fatigue, lupus, and multiple sclerosis. Type AB's tend to have the fewest problems with allergies, while heart disease, cancer, and anemia are medical risks for them.
With arthritis, Type O's, again, are the predominant sufferers because their immune systems are "environmentally intolerant," especially to foods such as grains and potatoes which can produce inflammatory reactions in their joints, says Dr. D'Adamo. Types A and B are the most susceptible to diabetes, while types A and AB have an overall higher rate of cancer and poorer survival odds than the other types.
Figuring out your blood type diet is one step, but if you are suffering from a particular disease you may want to go a step further. For instance:
A ketogenic diet has had great results with epilepsy and cancer. It works because it changes the very “fuel source” that the body uses to stay energized: Namely, from burning glucose (or sugar) to dietary fat.
Making that switch will place your body in a state of “ketosis,” when your body becomes a fat burner rather than a sugar burner. The steps are surprisingly simple:
-Cut down on carbs. No sugar (in any form).
-Increase your consumption of healthy fats.
Without glucose coursing through your body, it’s now forced to burn fat and produce ketones instead.
Once the blood levels of ketones rise to a certain point, you officially enter into ketosis.
This state results inconsistent, fairly quick weight loss until your body reaches a healthy and stable weight.
A Paleo diet consists of: Fresh fruits, fresh vegetables, fresh meat—the paleo diet is all about eating foods straight from the Earth. Anything that comes in a box, jar, or bag should be avoided on the paleo diet,
that means no grains, dairy, added salt, or legumes (including peanuts, beans, lentils, and soybeans). This is a great diet for those with Celiac disease, or any similar intestinal issues, and those with diseases caused by inflammation.
This diet's motto is eating to live instead of living to eat, and that can free up a lot of mental effort on your part, as your meals become very simple and straightforward. Meats, Veggies, Fruits. At least grocery shopping should be quicker since you'll only be visiting two sections.
A vegan diet relies on whole grains, fruits, vegetables, beans, peas, nuts and seeds for all it's nutrition and seems to be beneficial to diabetics, certain cancers, and heart disease. However, not all vegan diets are created equal.
For instance, poorly planned vegan diets may provide insufficient amounts of essential fatty acids, vitamin B12, iron, calcium, iodine or zinc (5).
That's why it's important to stay away from nutrient-poor, fast-food vegan options. Instead, base your diet on nutrient-rich whole plants and fortified foods. You may also want to consider supplements like vitamin B12.
Intermittent fasting is more about when you eat than what you eat (of course the best results will come from whole, nutrient dense foods.) The basic idea is to limit your eating time to 8 hours and fasting for 16 hours. Example, 11 am - 7 pm is eat time (breakfast, lunch, dinner, and even snacks in between).
7pm-11am No food. Though many would allow a bulletproof coffee in the morning, to feed your brain and get you through to your allotted eating time.
When you don't eat for a while, your body initiates important cellular repair processes and changes hormone levels to make stored body fat more accessible. It's great for inflammation, Alzheimer's, Oxidative Stress, and blood sugar regulation.
There are many variations to these diets as well, such as whether potatoes are acceptable or not. There are still debates within each of these factions, which is where the personal experience comes into play.
If you see great results with the occasional baked potato than by all means eat it, but if you notice issues avoid it and see if it makes a difference.
One diet does not fit all, like a suit it needs to be tailored to each individual, and yes trial and error can seem daunting, but nobody can tell you what is best for your body, that is between you and your gut, listen carefully.
