Previous literature has described obesity as a disease causing millions of deaths in the world but this paper claims that obesity is an eating disorder. Climatic conditions have a strong corelation with obesity and the availability of seasonal fruit and vegetables as well as the diseases which spread out in a specific season. All foods coming in a particular season are real source to combat seasonal health issues as a gift from God. Most of these diseases are related to season and eating not according to blood groups. Deficiency of certain major nutrients, minerals and vitamins also result in certain communicable and non-communicable diseases. There is a protein in blood of each individual known as lectin but these proteins have different functions in each blood group individual to combine with certain specific types of sugars in foods we eat and allow the blood to coagulate or not.

Food likes and dislikes are improtant information explaining types of lectins mostly present in a particular blood group type individual. Human mind keeps a record of likes and dislikes to inbuilt data. These food likes and dislikes are based on taste buds which could help to combat any disease with food like obesity. There is no any junk food made by God but we should choose foods according to our blood groups and what so ever it may be but is good for one blood group.

Most of the World’s scientists conducting human studies are not bothering about a strong biomarker that is blood group. While to be on the safe side they should know about distribution of four blood groups in different regions of the world and think unbiased that variable effects of these four different blood groups may pose different errors in research.

Similarly sensory scientists are reporting that there are basic four taste budds and these four taste buds are real source of selection of any food which ultimately become balanced diet and nutrition for a specific blood group individual (Sarfraz., et al. 2016)¹¹. There is need to conduct new research on BMI calculation on the basis of blood group and to monitor significant error in important research for world health. WHO should consult on these basis and arrange discussions as well as provide funds to conduct research to eliminate this critical error. On the basis of BMI in relation to specific tissues and relevant diet in Asian region where prevalence of blood group “B” is highest and also have high BMI as compared to “AB”, “O” and lowest in “A” But in the other regions which are relatively cold are having highest BMI in “AB” according to the prevalence of blood groups in the world. If variation occurs can be corrected by taking blood group specific diets. In relation to blood group “AB” having connective tissues as major tissues demanding high calcium and hot foods (Faiz, 2002)⁶. Many residents of cold regions are complaining about body pains and shrinking of veins due to highly cold climate and many are declared as asthmatic due to passing cold and dry air through nostrils in to lungs. Physicians irrespective of chilling climatic conditions are recommending inhalers. Sensory scientists say that bitter and astringent taste is liked by blood group “AB” people. Also medicines being sold in the market to reduce weight contain bitter plant extracts, which provide energy to the body to keep it warm and support the function of spleen. If function of spleen is perfect, the body will not be obese. One such food is bittergourd. As connective tissues of blood group “AB” are coldest part in the body will not support peristaltic movement and digestion of food untill and unless hot foods are not taken to keep the body warm (Peter and Catherine, 2000)⁹.

Ispagola husk is also producing very deletrous effects on AB blood group patients of constipation. It is a result of coldness and dryness in the climate. Regions in which the climatic conditions are severely cold and it causes dryness as the water clots resulting in low moisture in the air. The human can save themselves from coldness by putting warm clothes but low moisture in the air causes dryness of nostrils, dries up lung tubes causing asthma. Ispagola husk has strongly cool and wet (humidifying) effect on body, if taken continuously by three blood groups (A, AB and O) will produce paralysis in these three blood group indiviuals. In colder regions, the birth rate diminishes and male genitla organs shrinks and sperm count decreases. The blood group “A” is having nervous tissues as major tissues demanding nerves supporting foods (almond, walnuts, pine nuts, etc. as source of Zinc & Magnesium to activate 350 enzymes in their stomach) to became active, healthy and females to became pregnant. Shrunken ovaries will be unable to deliver healthy babies. In such regions birth of disabled babies are due to the chilling temperatures.

According to the data available on internet, regions having blood group “O” need red meat, table salt, MSG, Soy sauce, onion, ginger, garlic, hot red chilies, spices, red tomatoes and should not take bakery food items, dairy items except cow’s milk, and cow’s clarified butter (desi ghee).

Obesity in “AB” blood groups is most prevalent in cold climates (mostly European countries). This eating disorder becomes more prominent in coldest season in winter from November, 25^th to December, 11^th, which shows that this eating disorder is very common in cold countries. So, it is better for these people to live in warm or moderate climatic regions. Meian., et al. (2012)⁷ reported that peolpe having blood group “AB” are most vulnerable to heart attack and “O” is most resistant (research was conducted at Harverd School of Public Health and published in American Journal of Heart association) the study was conducted on 90,000 patients and was followed up for twenty years. We should avoid such marriages and climatic conditions which formulate blood group “AB” in offspring’s as to avoid heart attacks due to cold body conditions.

At the time of marriage blood groups should be taken in to consideration to have children with minimum health problems and select diet according to blood groups to remain healthy. Never plan a marriage with the possibility of transfer blood group “AB” in some children either they should plan to live in hot regions to avoid health problems. Marriages with female may result in disable children due to improper blood circulation and improper development of fetus. Similarly “A” males have more female babies in cold regions. There are some specific diseases which have close correlation with climatic conditions to give birth to female babies. The concept of balanced diet and nutrition needs revision in the light of four blood group individuals on the basis of their active relevant tissues and their different energy and specific nutrient requirements as Individuals having blood group “O” has muscular, “A” has nervous, “B” has epithelial and “AB” has connective tissues (Babar, 2005)⁸. Similarly these four blood groups have different taste buds as “O has most liking of saltish taste (helpful for the highest production of HCl in the stomach- also need Iodine to support energy production in the body due to heavy and quick loss, this blood group mostly prevails in hot regions of the world near equator). The most prevalent blood groups in the world are 62% “O”, 21% “A”, 16% “B” and the least is 1% “AB” (Beckman, 2008)³
