The idea that there are different diets for different body types was first proposed by psychologist William H. Sheldon in the 1940s. Sheldon categorised body types into three somatotypes: ectomorph, mesomorph, and endomorph, each with distinct physical traits. While there is limited scientific data to support this theory, some studies have found correlations between body composition and physiological traits, suggesting that our diets should be tailored to our body type. For instance, ectomorphs tend to be leaner and may require a higher-carbohydrate diet, while mesomorphs may require more protein, and endomorphs may benefit from focusing on healthy proteins and fats. However, it's important to note that individuals rarely fit neatly into one category, and there are many exceptions to the rule.
Characteristics and Values of Different Body Types
| Characteristics | Ectomorph | Mesomorph | Endomorph |
|---|---|---|---|

Ectomorphs: Lean and lanky, they can handle more carbs and have a higher metabolism
Ectomorph body types are typically characterised as thin, long, and lanky, with a smaller bone structure and a narrow hip-to-shoulder ratio. People with this body type tend to have a faster metabolism and can lose weight easily, but they also struggle to build muscle mass.
Ectomorphs can generally handle a higher intake of carbohydrates than other body types. This is because they have a higher insulin sensitivity to process carbs, and their faster metabolism means they can consume carb-heavy dishes without the same risk of weight gain as other body types. Ectomorphs can also eat more meals throughout the day than other body types, with some sources recommending 5-6 small meals every few hours to help them stay full and satisfied.
However, it is important to note that not all carbohydrates are created equal. Ectomorphs should focus on consuming complex carbohydrates from healthy, whole grain, and high-fibre sources, such as fruits and vegetables, and whole wheat rice and pasta. These foods provide quick hits of energy and keep the body functioning optimally. In addition, ectomorphs should also incorporate healthy fats, such as olive oil, nuts, and seeds, as well as lean protein sources, such as fish, tofu, or chicken.
To build muscle mass, ectomorphs should focus on a dedicated training and nutrition plan. In addition to consuming more calories overall, they should also increase their protein intake, with some sources recommending 1.5-1.6 g of protein per pound of body weight. Supplements like whey protein, BCAA, or casein can also help with muscle growth, but only under the guidance of a nutritionist or dietitian. Strength training and weight training are also important components of an ectomorph's exercise regimen, with a focus on slow, heavy weights and multiple sets of moderate repetitions.

Mesomorphs: Athletic builds that gain muscle easily, they require a higher calorie intake
While there is a lack of scientific data to support the theory of somatotypes, it is still a popular concept in the health and fitness industry. According to this theory, there are three main body types: ectomorph, mesomorph, and endomorph. Each body type is said to have distinct physical traits and respond differently to diet and exercise.
Mesomorphs are characterised by their athletic, muscular build. They typically have a medium frame with a rectangular or boxy shape and a higher percentage of muscle mass compared to body fat. Due to their higher muscle mass, mesomorphs often require a higher calorie intake than other body types to support their energy needs and promote muscle growth and repair. A well-balanced diet consisting of 40% carbohydrates, 30% protein, and 30% fat is often recommended for mesomorphs. This translates to roughly equal parts protein, fats, and carbohydrates.
Protein is particularly important for mesomorphs as it helps to build and repair muscle. Good sources of protein include eggs, white meats, fish, beans, lentils, and high-protein dairy like Greek yogurt. Carbohydrates are also necessary to provide energy for workouts and fill up the body's glycogen stores. Mesomorphs can consume a moderate amount of carbohydrates without negatively affecting their blood sugar levels due to their good insulin sensitivity. Whole grains, starchy vegetables, and healthy fats are recommended sources of carbohydrates and fats for this body type.
In addition to diet, mesomorphs can benefit from a tailored workout plan to achieve their fitness goals. They typically have an easier time building and maintaining muscle mass and can benefit from weight training or strength training combined with cardio. However, mesomorphs may also hit fitness plateaus, so varying workouts and intensities can help keep them challenged and promote continued progress. Overall, while there is no one-size-fits-all approach, understanding body types like mesomorphs can provide guidance for individuals seeking to optimise their diet and exercise routines to meet their specific goals.

Endomorphs: Prone to storing carbs as fat, they should focus on nutrient-rich whole foods
While there is a lack of extensive research on how a person's somatotype might inform their diet and exercise habits, there is some data on body composition differences. According to psychologist William H. Sheldon, there are three types of physiques: ectomorph, mesomorph, and endomorph, each with distinct physical traits. Endomorphs are prone to storing excess calories as fat and have a higher body fat percentage with less muscle mass than other somatypes.
Endomorphs should focus on nutrient-rich whole foods, including lean quality protein, complex carbohydrates, and healthy fats. They should limit their consumption of refined carbohydrates, processed foods, and high amounts of added sugars and trans fats. Carbohydrates should come primarily from vegetables and, to a lesser extent, high-fiber sources like whole grains. Endomorphs can consume some carbohydrates, but they should focus on complex carbohydrates and limit simple carbohydrates, like white bread and sugar, which can cause blood sugar spikes and be stored as fat.
A sample endomorph meal plan might include a higher protein intake (40% of calories per day), a good amount of healthy fats (40% of calories per day), and a lower carbohydrate diet (20% of calories per day), focusing on fiber-rich veggies. Endomorphs should also incorporate regular aerobic exercise, such as running, biking, or dancing, to lose weight and reduce belly fat.
It's important to note that individuals rarely fall under the true definition of one of these body types and are often a hybrid of two or even three types. Additionally, there are many exceptions to the rule, and the idea that there is a one-size-fits-all approach to diet and exercise based solely on body type is not supported by scientific data. As such, it is always recommended to consult a registered dietitian-nutritionist to find the best nutrition plan for your individual needs.

Hybrid body types: Most people exhibit characteristics of multiple body types
While there are three main body types, most people exhibit characteristics of multiple body types. These hybrid body types are a combination of two or even three of the main somatotypes. For instance, ecto-mesomorphs are lean and muscular, meso-endomorphs are strong with bulkier muscles, and ecto-endomorphs are thin but lack muscle tone.
Daily exercise, diet habits, metabolic changes, and lifestyle factors can influence an individual's body type, making it challenging to identify their natural metabolic state. To determine their body type, Catudal suggests considering their body shape during their late teens or early twenties.
The theory of somatotypes, proposed by psychologist William H. Sheldon in the 1940s, categorizes individuals into ectomorphs, mesomorphs, and endomorphs, each with distinct physical traits. Ectomorphs are naturally leaner and find it challenging to build muscle or gain fat. They have a higher carb tolerance due to their efficient metabolisms and can handle a higher carbohydrate intake. However, they should be cautious with high-fat diets as their metabolisms crave carbohydrates.
Mesomorphs are more muscular and athletic, with the ability to gain and lose weight easily. They typically require a higher calorie intake and a diet that includes more protein than the other body types. A balanced approach to macronutrients, including fats, complex carbs, and proteins, is ideal for this body type.
Endomorphs tend to have a higher percentage of body fat and often carry it in their lower body, including the midsection, hips, and thighs. They are skilled at converting carbs into sugar and storing them as fat. Therefore, they should focus on consuming nutrient-dense foods, including lean protein, complex carbohydrates, and healthy fats, while being mindful of their carb intake.

Somatotype limitations: There is a lack of scientific data supporting somatotype-based diets and exercise
Somatotypes, or body types, refer to the theory that everyone falls into one of three inherited body types: ectomorph, mesomorph, and endomorph. Each somatotype is said to have specific characteristics that influence how the person processes macronutrients, handles exercise, holds weight, and moves. For instance, ectomorphs are believed to have lower body fat percentages and higher strength-to-bodyweight ratios, making them better suited for long-duration aerobic exercise. In contrast, endomorphs, who carry more muscle and fat, are thought to excel in heavy weightlifting exercises. Meanwhile, mesomorphs are considered more athletic and strong, able to gain and lose weight easily.
While the concept of somatotypes provides a simple framework for understanding how diet and exercise may be tailored to different body types, it has notable limitations. One significant limitation is the lack of extensive scientific data and research supporting somatotype-based diets and exercise routines. Although some studies have found correlations between somatotypes and certain physiological traits, the overall body of research is limited. Nutritional scientist Nanci Guest, PhD, RD, CSCS, notes the lack of scientific evidence, stating that "there isn't enough science to suggest that you can exercise for your type."
Additionally, the somatotype theory does not account for the vast diversity in human body types. People often exhibit characteristics of multiple somatotypes or fall somewhere in between, blurring the clear-cut categories proposed by the theory. This limitation is acknowledged by Guest, who emphasizes that "people exist in between each one of the body types — we come in every shape out there." The concept of hybrid types has been introduced to address this limitation, recognizing that individuals rarely conform exclusively to one somatotype.
Furthermore, the theory of somatotypes has been rejected and disproven as a means to accurately predict or determine individual physiology, metabolic differences, or responses to training and diet. While it may provide a starting point for understanding general tendencies, adhering rigidly to somatotype-based recommendations may hinder individuals from achieving their fitness goals and developing their optimal physique. As people progress in their fitness journeys, their bodies change, and a somatotype-based approach may become less relevant or effective.
In conclusion, while the concept of somatotypes offers a simple framework for understanding diet and exercise in relation to body types, it is important to recognize its limitations. The lack of extensive scientific research supporting somatotype-based approaches, the diverse nature of human body types, and the potential hindrance to long-term progress underscore the need for caution when relying solely on somatotype-based diets and exercise routines. Consulting a professional dietitian and focusing on individual goals and progress can provide a more personalized and effective approach to health and fitness.

Frequently asked questions
The three main body types, or somatotypes, are ectomorph, mesomorph, and endomorph.
Ectomorphs are naturally long and lean and have a hard time gaining fat or muscle. They can typically tolerate more carbohydrates and should focus on a diet of predominantly carbohydrates, with lean protein and fats split almost evenly for the remaining calories.
Mesomorphs are solid, athletic, and strong and tend to find it easy to maintain a stable weight. They require a higher calorie intake and their diets should contain more protein than the other body types. Experts recommend a diet of roughly equal parts protein, fats, and carbs.
Endomorphs have a higher percentage of body fat and tend to carry it in their lower abdomen, hips, and thighs. They are good at converting carbs into sugar and storing them as fat, so they should cut back on their carb intake and focus on healthy proteins and fats.
Body type is determined by skeletal frame and body composition. Most people are a hybrid of two or even three types and may exhibit unique characteristics from each. Your body type may have changed due to lifestyle factors, daily exercise, diet habits, and metabolic changes.
