Many diets are caused by different diets, focusing on body type or blood type. The basis of a healthy diet should be the balance of nutrients and calories, as well as the supply of essential vitamins and minerals, therefore the division of food based on certain characteristics of the body is not completely rational.
Eating by blood type
The theory of proper nutrition for each blood type is that people with different blood types process food differently. According to the theory, people on a diet specific to the blood type can improve health and reduce the risk of chronic diseases such as cardiovascular disease.
What is a blood type diet?
There are 4 different diets, one for each blood type.
Type A: people in the second group belonging to farmers. They are instructed to eat plant foods without red meat. Type A diets should most closely resemble vegetarian diets.
Type B: people with the third group or nomads. They need to eat plants and can eat meat (except chicken and pork), some dairy products. They should avoid wheat, corn, lentils, tomatoes and several other foods.
Type AB: people with the fourth group or riddles. They are a "mix" between type A and B and should eat a diet rich in seafood, tofu, dairy, beans and cereals. However, they should exclude beans, corn, beef and chicken.
Type O: people with the first group or hunters. They should eat foods high in protein, the diet is rich in meat, fish, poultry, some fruits and vegetables, but it is worth limiting cereals, legumes and dairy products (the diet is very similar to paleo).
Most people who end up adopting this style of eating do so because they are looking for a solution to a health problem or are involved in preventing complications.
Will a blood type diet help?
For centuries, people have eaten food without being guided by their blood type, while not having problems with weight and health. All the health problems we see today (especially chronic diseases and weight problems) and the deterioration of our health are completely unrelated to our blood types.
Many of our grandparents and generations before them lived long and healthy lives. They were much healthier than most people today. They probably didn't eat according to their blood type (and often didn't even know it). Therefore, it is logical to conclude that a significant contribution to their health and longevity, obviously, is not the blood type diet, but the lifestyle itself. This means that you can be healthy and live a long life without eating a strict blood type diet.
Nutrition according to body type
Can body type - be it ectomorphic (asthenic), mesomorphic (normosthenic) or endomorphic (hypertensive) - determine what you need to eat to be healthy and slim? Even scientists did not give a definite answer. Food for your body type or body type is one of the most discussed nutritional topics in our society.
There are two types of people:
- Emphasize too much on body writing.
- Reject body types and their impact on every area of life.
Like many hotly debated topics, the truth is somewhere in between. For most people, nutrition according to body type is not necessary or important. For them, this is simply not the most effective tool for meeting their needs and goals. But body type nutrition can be helpful for some people in a few very specific situations.
You've probably heard of three body types:
- Ectomorphs (often called asthenics in our country) with thin, narrow, delicate, fragile, linear body features and weak muscles.
- Endomorphs (or hypertensives) with soft, round features, broad bone and overweight.
- Mesomorphs (normostenics) have broad shoulders, narrow at the waist and hips, muscular, compact and athletic.
The somatotype describes such components of the body as fat mass, muscle mass and the ratio between them. Therefore, over the years, somatotype has become an assessment tool for health professionals and researchers, similar to the body mass index (BMI). Although none of them is a perfect system, BMI and somatotype allow people to be classified into specific groups.
Do you need to eat only for your body type?
In general, no. It is important to note that these are just general conceptual categories - principles that can potentially help you with your food choices. Body type is a reason to think about possible differences in metabolism, type of activity and nutritional needs.
For the average person who just wants to look and feel their best, a body type diet is not necessary. It also makes eating unnecessarily complicated. For these people, there are much simpler and more affordable strategies - you need to eat less fat, sweets, more vegetables and fruits.
So who benefits from eating according to body type? There are usually two types of people who end up in this camp: professional athletes and people who cannot achieve their goals with basic eating strategies alone.
In these very rare cases, changing the breakdown of macronutrients based on body type (or in particular the ratio of fat to muscle) can be an effective strategy, but only after the diet is really healthy in terms of calories and BJU.
What does everyone need?
Regardless of blood type, body type and any other characteristics, everyone needs a healthy and balanced diet. Includes calorie consumption according to their consumption. These indicators are determined by age, gender and lifestyle. On average, a man needs about 2500 kcal per day, a woman - about 2000 kcal.
If you need to gradually lose weight, create a calorie deficit of 5-10% per day, then excess fat will begin to melt, regardless of body type and blood type. It is important to consume as much natural food as possible and as few food chemicals, refined, processed foods and fast food as possible. Reduce as much salt, sugar, trans fats as possible. And then it will be possible to solve problems with both health and figure.
