Since there's been quite a few losing weight threads just wondered if anyone knew anything about this diet.

I've tried it for a couple of weeks and the weight loss is quick and i felt great when i was on it. It's just that i have no willpower to stay on it.

I'm type-o and it says that i should avoid dairy products and bread and refined stuff. After i cut out these things man did it feel great. My bowels were thanking me. Regular and i also had no heartburn at all (which i quite often have).

I also lost quite a bit of weight in those 2 week periods that i was on it. The thing is i didn't feel tired or anything but it's just too difficult for me to cut out on bread and having to buy the special stuff like dairy free this and gluten free that.

What the diet also recommended for my bloody type was intense exercise. Stuff like martial arts or jogging. It says that i should feel invigorated everytime i do intense exercises. I never realised it before i read the book but it's actually true. I've always felt better after an intenses session at the gym.

For other bloody types like A i think you're supposed to cut down on meat 'cos supposedly you produce less acid in your stomach and therefore digest slower.
 
Any diet that doesn't eliminate critical nutrients will work. Just the fact of being "on a diet" will make most people reduce intake. Add exercise -- which can help you lose weight even with your old eating habits, and there you have it -- amazing success.

Nothing in excess.
 
I did not find that article particularly useful since sceptics are sceptics. So they always find something wrong about something without ever experimenting on it themselves. Some people don't believe in qi and doctors hate chiropractors and some people still don't believe in acupuncture.

I was more interested in real life experience. So far when i've tried it, i've lost weight and do feel better in terms of digesting food and overall how my stomach feels (i.e. no heartburn, no diarrhoea, my ibs is reduced).

Thanks for the link anyway.
 
Not to turn this into a skeptics-vs-non thread, but that's a misrepresentation of the skeptical mindset. The skeptical mindset is about requiring an appropriate amount of evidence for a given claim before that claim is provisionally accepted as true. For ideas such as "people with different blood types need such widely differing nutrient levels that you can structure a diet around it", we require a large amount of evidence. Since the claim is presented as scientific in nature, and yet is counter to accepted and demonstrated principles in the relevant field, it is referred to as "pseudoscience", or more colloquially "bullshit".

If you want to lose weight, consume fewer calories than you burn or get liposuction.
 
Understood.

Have they ever done a study on blood type diet? It's just funny that so many people have had good experience with it and yet there has been no study done on it.

I just find it easier to believe that due to the differences in everyone's body that a ONE SOLUTION THING like eat less calories wouldn't be optimal.

Anyway, a lot of doctors don't believe in traditional medicine 'cos they haven't given any scientific evidence but i've had good experience with traditional chinese medicine. So i like to keep my mind open and actually try it out myself.

Things like diets and remedies and what might or might not work on different people is so complex that you can't really make simplistic claims for, or against, anything. What it really comes down to, if it works for you, great, do that. If it doesn't, try something else. The reason for requiring scientific evidence for something is so that you can say, with some degree of certainty, that THIS process will work X% of the time in Y circumstances. It can also give some reassurance that there might not be undesired side effects. Not always of course, but it's your best defence.

If you feel that XYZ diet makes you feel good and you lose weight and there are no obvious ill effects then great, keep doing that. Personally I think different diets with funny names are simply adding a psychological effect that, if it appeals to you, make it easier to stick to. What it really comes down to is if you eat an appropriate amount of nutritious and balanced food and get plenty of exercise you will look and feel better and be healthier. You can call this the gajinoz diet if you like. :)
 
Frankly I've never run across any serious scientific support for a blood type diet. On the other hand you seem to have found some things that have benefits for you regardless of whether that is related at all to your blood type. If you've had issues with intestinal irritation you may want to determine what caused your problem. Try eliminating single types of foods until you find what bothers your intestines. It is pretty common to have a sensitivity to milk products. If that seems to be the problem you might test to see if taking lactase (a milk digesting enzyme available at grocery stores--at least in the USA) allows you to consume milk products without problems. You could just have lactose intolerance. If milk isn't the problem you could see if you have a problem with gluten. It is a lot less likely that you have problems with both gluten and dairy.

If you want to lose weigth it helps anyone to reduce their consumption of dairy fats and quick burning carbohydrates. Just replace some of the carbohydrates that you eat with some fruit or green vegetables. Likewise getting more exercise will help anybody to lose weight.

A lot of diets work simply by reducing the variety in your diet. With less variety it is less appealing to eat lots of food. The big exceptions are sugars which are almost addictive and buttery fats. Cut down on sweets and fried foods and eat a limited range of meats and dairy plus unlimited fruits and vegetables and you'll probably lose weight. Nobody overdoses on fruits and vegetables.
 
Point44, I'd like to try that myself, my blood type is RH-negative. Can you send me a link on the internet if you don't mind. Hey, let's see what it's all about. :)
 
Most traditional cultures understand the human body to be one of 4 different 'types'. The Indians have their Ayruvedic system, the Chines Ying/Yang, even our Australian Aborigines with their 'Skin' system. I read a book about eating according to my blood type and was interested to note that it came up with very similiar advice to what eating according to my Ayruvedic 'type' does.

If western science hasn't proven it's worth then it may not have come up with a sophisticated enough experimental methodology - remember much of western science is driven by stakeholders with an investment in the 'outcome' of the research. Research showing the health benefits of wheat is invariably sponsored by the wheat growers, the same with dairy and meat. Remember cigarette companies used to quote 'research' saying that smoking did not cause cancer.

Bit I also reckon you don't need a blood type system or ancient teachings to learn how to eat well. Start to become conscious of what foods you are eating - keep a dairy of it for a month - and some obvious patterns will emerge. You will start to become conscious of what sugar, wheat, meat, dairy, salt (and sodium in general) does to your mood and energy levels. You'll also become conscious of the double whammy that some addictive foods create - not only bloating you and harming your health but triggering you to crave more of the same. That also takes that false self judgement of 'will power' out of the equation.

Also, what Jeff said.

Blood Type Diet

Yes ming65.
I don't know whether it's really because of my blood type or just a coincidence that i'm reducing eating certain foods. Anyhow....i've got a sensitive stomach. I've got IBS and get heartburn all the time. Probably a large percentage of it is due to being overweight which i am trying to remedy. I just find that certain health diets don't agree with me. I hate veggies. So that's difficult. I also can't take milk.

There're other stuff i'm sensitive to as well. Chocolates make my stomach hurt. So does coffee. I used to love coffee and i don't know how the hell i started getting sensitive to it. So sometimes i still can't resist the occasional mocha or cappucino.

So my plan now is to start cutting out sugar and refined food. Trying to reduce bread as well. But it's just such a convenient food. It's tiring having to cook meat all the time.
 
I'm an O negative blood type. I've always eaten mostly meat, and I never gain weight. Then again that's not saying much since I'm never overweight, regardless of what I eat. I think it has more to do with metabolism than blood type, but who knows. Or maybe because I've always kept fit.

edited to add:
I found this article on blood types, that mixes fact with...err...fiction.
For entertainment purposes only! :D

I think one reason to not bother testing this blood type theory as it relates to the case in question is, if you are suffering from indigestion and heartburn, your doctor would probably already tell you to avoid dairy products as milk can cause both. "Refined" foods are generally not recommended for anyone anyway.
 
Well I looked at the site and didnt see a plan for my blood type but learned the RH means rhesus, I guess like the rhesus monkeys and that might explain alot with me. Back to the long grain wild rice with no salt and low sodium cereal.

Nah, that sounds way too complicated for me. I'll just cut down on fats and carbs and get a lot more exercise. :)
