Do you ever feel that your gym efforts are in vain since your desired outcomes aren't being met? Although you may have lost weight, little has changed about the way you look. The improper locations are still where you have fat.

Researchers and dietitians now assert that this can be the result of you not eating or exercising in accordance with your blood type. What you should eat and how much exercise you should get depends on your blood. Your blood type is your genetic blueprint, because it tells more about you and your body than anything else.

Discover the best workouts and diets for your blood type:

Type O

Your genetic composition is most similar to the cavemen and women who spent their days hunting and defending themselves against predators 

Best exercises: Because you're no longer chasing your meals, you tend to be strong and athletic (gotta love those powerful arms and legs). As a result, you enjoy high-intensity exercises like interval training, running, and plyometrics. You exercise to relieve tension and anxiety and need it more than other blood types to improve your mood.

Best diet: You do best by avoiding a lot of processed carbs and dairy—basically, very similar to eating Paleo.

Type A

Although they were active, ancient farmers, whose DNA is similar to yours, spent their days engaging in slower, less strenuous activities like cultivating crops.

Best exercises: Intense exercise causes muscle soreness and stiffness while raising your levels of the stress hormone cortisol. Pilates, yoga, Tai Chi, and isometric exercises are the best choices if you want to relax, focus, and protect your joints.

Best diet: One that closely resembles a vegetarian diet, with plenty of fresh produce, whole grains, and fish on your plate. Foods to avoid include corn, tomatoes, buckwheat, wheat, lentils, sesame seeds, and peanuts as well as meat and fish. 

Type B

Your ancestors were nomads, so although they migrated frequently, it was at a slower rate than those prehistoric people. They also moved in groups. Best exercises: weight training and group cardio exercises with a little less impact, like tennis or cycling. 

Best diet: Foods best suited for this blood type include vegetables and fruits, low-fat dairy products, eggs and certain types of meats. Of all the blood groups, B is the most balanced as it carries both the ability to thrive in changeable conditions and the genetic potential for malleability. This explains why the types of foods that can be eaten by Type B people hail from both the animal and plant kingdoms. Despite their ability to adapt, there are still some foods which people of this blood group should avoid – peanuts, wheat, tomatoes, lentils, buckwheat and chicken. 

Type AB

You contain both Type A and Type B DNA components in your body.

Best workouts: You'll be more likely to continue with gentle exercise, such as walking, hiking, golfing, or dancing, as high-power cardio sessions tend to cause muscle and joint stiffness. Yoga and Tai Chi can help you maintain a positive mood as well as the flexibility of your muscles and joints because you also have a tendency to internalize your anger.

Best diet: Avoid caffeine, alcohol, and cured or smoked meats if you have this blood type. Meats that have been cured or smoked can cause cancer in those with low stomach acid levels. People of Type AB can adjust to meat in the same way as Type B can. This means that these individuals frequently have insufficient stomach acid to fully digest and metabolize meats, which results in the meats being stored as fat.

The best foods for people with this blood type are fish, particularly salmon, mahi-mahi, sardines, and tuna. Fruits, vegetables, nutritious grains, dairy products like milk and yogurt, and dairy foods like milk and yogurt help this blood type lose extra protein, which could otherwise be stored as fat.
