There are several factors that determine a balanced diet, and while the basic principles of what constitutes a healthy diet are universal, individual characteristics such as age, gender, lifestyle, and physical activity level can also play a role. Nutritional needs can vary between individuals, and men and women may require different nutrients due to biological differences. For example, men generally require more calories than women due to greater muscle mass, and gender-specific hormonal differences can also impact dietary needs. Socio-economic factors, cultural traditions, and geographical aspects also influence dietary habits and can contribute to gender-related differences in obesity rates. Ultimately, a balanced diet should be tailored to meet an individual's unique physical needs, fit their lifestyle, and reduce their risk of disease.
| Characteristics | Values |
|---|---|
| Energy intake | Men require more calories than women due to greater muscle mass. |
| Macronutrients | Both men and women should obtain 45-65% of their calories from macronutrients (carbohydrates, fat, and protein). |
| Fat | Men tend to store visceral fat in the abdominal region, while women accumulate subcutaneous fat on the hips and thighs. Only visceral fat is linked to metabolic syndrome, cardiovascular disease, and certain cancers. |
| Weight management | Men experience higher rates of overweight and obesity despite typically consuming more calories. |
| Socio-economic factors | Gender differences in dietary habits are influenced by socio-economic status, with higher-income individuals having greater access to healthy foods and cultural norms dictating body image ideals. |
| Nutritional products | Gender-specific products may not always be beneficial or detrimental to health. Reading nutrition labels is essential to making informed choices. |
| Individual variation | Individual nutritional needs may vary more within a gender group than between men and women. Age, physical activity, height, weight, and physiological factors (e.g., pregnancy, breastfeeding) also play a role. |
| Balanced diet | A well-balanced diet for both genders includes fruits, vegetables, legumes, nuts, whole grains, and healthy fats while limiting added sugars and sodium. |

Calorie intake
Men tend to have higher energy intake and energy density in their diets, often deriving a larger percentage of their energy from lipids. Despite requiring fewer calories, women generally exhibit a better dietary profile, with a higher percentage of energy derived from carbohydrates. These differences in dietary intake and eating behaviours may be influenced by gender-specific motivational variables.
While men generally require more calories, it is important to note that both men and women should ensure their energy intake (calories) aligns with their energy expenditure to maintain a balanced diet. Excess calories, particularly from foods and drinks high in free sugars, can contribute to unhealthy weight gain and obesity. To avoid this, total fat consumption should not exceed 30% of total energy intake, with saturated fats making up less than 10% and trans-fats less than 1%. Additionally, limiting free sugar intake to less than 10% of total energy intake is recommended, with further reduction to less than 5% offering additional health benefits.
The specific calorie requirements for individuals may vary, and factors such as physical activity, height, and weight play a significant role. For example, a highly active woman may require more calories than a sedentary man. Therefore, it is essential to consider individual characteristics when determining the appropriate calorie intake for a balanced diet.
In summary, while men generally have higher calorie needs than women due to their greater muscle mass, maintaining a balanced diet involves ensuring that calorie intake aligns with energy expenditure and adheres to recommended guidelines for fat and sugar consumption. Individual characteristics and activity levels also influence the specific calorie requirements for each person.

Macronutrients
Energy Requirements
On average, men require more calories than women. For instance, a sedentary 35-year-old man needs around 2400 calories daily, while a woman of the same age needs about 1800 calories. This difference is primarily due to men typically having more muscle mass, which demands more energy to sustain.
Protein
Protein is an essential macronutrient for muscle growth and repair. Men who aim to build muscle need approximately 0.84 grams of protein per kilogram of body weight per day. For an 80-kilogram man, this equates to about 60 grams of protein daily. Protein-rich foods include meat, poultry, fish, dairy, legumes, lentils, eggs, and nuts.
Fat
Men and women should limit their total fat intake to no more than 30% of their total energy intake. Saturated fats, in particular, should constitute less than 10% of total energy intake, while trans fats should be below 1%. Men tend to accumulate visceral fat, especially in the abdominal region, which is positively correlated with the risk of type 2 diabetes, metabolic syndrome, cardiovascular diseases, and certain types of cancer. Thus, men should be mindful of their fat consumption and ensure it aligns with their energy expenditure to maintain a healthy body composition.
Carbohydrates
Carbohydrates are a vital source of energy for the body. While specific recommendations may vary, a balanced diet should include a variety of whole grains, fruits, and vegetables.
In summary, while the types of macronutrients remain consistent across genders, the quantities and specific recommendations may differ. Men generally require more calories and protein due to their higher muscle mass. They should also be mindful of their fat intake to mitigate potential health risks associated with visceral fat accumulation. Women, on the other hand, may require fewer calories, especially if they experience a decrease in muscle mass or an increase in body fat during certain stages of life, such as pregnancy or hormone therapy. It is important to note that individual factors, such as age, physical activity level, and lifestyle, also play a significant role in determining macronutrient needs.

Portion sizes
For adults, the recommended daily calorie intake is generally around 2,000 calories per day. However, this can vary based on individual factors such as age, height, weight, and activity level. Men typically require more calories than women due to having more muscle mass and tending to be larger in stature. For example, the recommended daily calorie intake for women is often around 1,600 to 2,000 calories, while for men, it can range from 2,000 to 3,000 calories or more.
To ensure a balanced diet, it is recommended to make half of your plate fruits and vegetables, focusing on whole fruits and a variety of colourful vegetables. Whole grains should also make up a significant portion of your diet, aiming for about a quarter of your plate. Include whole wheat, barley, wheat berries, quinoa, oats, and brown rice, as these have a positive impact on blood sugar and insulin levels.
Protein-rich foods such as meat, fish, eggs, and beans are essential, but it's important to be mindful of portion sizes, as these foods can be calorie-dense. Similarly, dairy foods like yogurt and cheese are nutritious, but the full-fat varieties should be consumed in moderation, with low-fat or fat-free options being preferable.
It's worth noting that portion sizes outside the home, such as in restaurants, tend to be larger than suggested serving sizes. Therefore, it may be helpful to start with smaller portions and assess your hunger levels before opting for a second helping. Using smaller plates and bowls can also assist in controlling portion sizes and preventing overeating.
In summary, portion sizes for a balanced diet will vary depending on individual factors, but by following general guidelines, such as the Healthy Eating Plate, and being mindful of calorie intake and nutritional needs, individuals can customise their portion sizes to fit their unique needs and promote a healthy lifestyle.

Lifestyle
While biological differences between men and women do impact nutritional needs, individual differences within each gender group are greater. Age, physical activity, height, weight, and whether or not a person is pregnant or breastfeeding all play a role in how many calories a person needs. For example, men generally require more calories due to having more muscle mass, which requires more energy to sustain. However, men and women should both focus on a well-balanced diet that includes fruits, vegetables, whole grains, and limits saturated fat, added sugar, and sodium.
Additionally, physical activity levels vary depending on gender, with men generally engaging in more energy-intensive activities and requiring more calories as a result. Women, on the other hand, may focus more on weight management and tend to be more willing to follow dietary advice, as seen in an Italian study where female type 2 diabetes patients were more receptive to dietary recommendations than their male counterparts.
Portion sizes also differ between genders, with men typically requiring larger portions due to their higher caloric needs. However, it is important to note that individual appetite and energy expenditure vary, so it is essential to adjust serving sizes accordingly.
Overall, while gender plays a role in dietary habits, it is crucial to prioritize a balanced diet that meets your unique physical needs, fits your lifestyle, and reduces your risk of disease. Consulting with a healthcare professional or registered dietitian can help individuals design a personalized nutrition plan that considers their gender, age, activity level, and specific health goals.

Health beliefs
A Swedish population-based survey examined gender differences in perceived food healthiness and food avoidance. The results indicated that around 50% of participants avoided sugar and sweetening agents, while fewer avoided saturated fat and salt. Women were more likely to avoid sugar and sweetening agents than men. This study highlights that health beliefs can influence dietary choices, with individuals avoiding certain foods or components due to perceived unhealthiness.
Finnish research revealed gender gaps in health information-seeking behaviour, with women actively seeking health-related information to a greater extent than men. Women also tend to pay more attention to how their purchases, including food choices, affect their health. These differences in health beliefs and behaviours contribute to varying dietary intake between men and women.
Cultural and socio-economic factors also influence health beliefs and dietary behaviours. For example, in some cultural environments, chubbiness is associated with richness, which may impact food choices and perceptions of health. Additionally, income and food prices affect the availability and affordability of healthy foods, shaping individual dietary patterns.
While biological differences between genders exist, such as men generally having more muscle mass requiring more energy, the basic principles of a healthy diet remain consistent. A well-balanced diet that includes fruits, vegetables, legumes, nuts, whole grains, and healthy fats is recommended for both men and women. However, individual characteristics, such as age, lifestyle, and physical activity levels, should be considered to tailor dietary patterns to meet specific needs and reduce the risk of disease.
In conclusion, health beliefs vary between men and women, influencing their dietary behaviours. Understanding these beliefs is crucial for developing effective health promotion initiatives that encourage balanced and nutritious dietary patterns in both genders.
