Vegan Diet Macros: What's The Ideal Ratio?

A vegan diet is a plant-based eating plan that excludes meat and dairy. While it is associated with several health benefits, some have questioned whether it can provide a balanced intake of macronutrients. Macronutrients, or 'macros', are the nutrients required to fuel your body and maintain healthy functioning. They include protein, carbohydrates, and fats, each of which plays a unique and vital role in your body. This article will explore how to ensure your vegan diet provides the right balance of macros to support your health and fitness goals.

Carbohydrates: 40-45% of your diet should be carbs, but you may need more to compensate for indigestible fibre

Carbohydrates are an essential part of a vegan diet, and it is recommended that 40-45% of your diet should consist of carbs. However, it is worth noting that this percentage can vary depending on your specific needs and activity level. For instance, endurance athletes may perform better with a higher carbohydrate intake, while those looking to lose weight may need to reduce their carb intake.

When following a vegan diet, it is important to ensure that you are consuming enough fibre, as it is associated with several health benefits, including a reduced risk of heart disease, diabetes, and obesity. Fibre is a non-digestible carbohydrate found in plant-based foods such as legumes, whole grains, fruits, vegetables, and seeds. The American Heart Association recommends a daily intake of 28 grams of fibre, but most people do not reach this target. A vegan diet can help increase your fibre intake, as it is naturally abundant in plant-based foods.

However, it is important to note that not all fibre is digestible, and it is recommended that vegans consume about 50-75% of their fibre intake in the form of digestible carbs. This is because fibre is counted as a carbohydrate on food labels, but most of the fibre consumed cannot be broken down and does not provide energy for the body. Therefore, if you are consuming a significant amount of fibre, you may need to increase your carb intake to compensate for the indigestible fibre. For example, if you consume 50 grams of fibre per day, you should aim for at least 37.5 grams of digestible carbs to ensure your body has enough fuel, especially if you are active and trying to lose weight.

To ensure you are getting enough digestible carbs, focus on including a variety of whole grains, fruits, and vegetables in your diet. Ancient grains like barley, teff, amaranth, and millet are excellent sources of nutrition and can add variety to your meals. Additionally, non-starchy vegetables and low-carb fruits can provide essential nutrients without adding too many extra calories or carbohydrates.

Protein: 12-14% of daily calories should be protein, but athletes may need 19-27%

Protein on a Vegan Diet

Protein is one of the three main macronutrients that make up the food you eat. It is an integral part of a healthy diet, along with carbohydrates and fats. Protein is crucial for muscle growth, maintenance, and recovery from workouts, day-to-day muscle stress, and injury and illness recovery.

Since animal-based products are the most common sources of protein, this macro may fall short when eating a plant-based meal plan. Vegan diets tend to be lower in protein, although usually still within the recommended guidelines for protein intake. Several studies suggest that the typical protein intake ranges from 12% to 14% of daily calories, which is adequate for general health according to the Dietary Guidelines for Americans (DGA).

If you are a vegan athlete, you may want to consume more protein than 14%. The International Society of Sports Nutrition (ISSN) suggests that physically active people should consume 1.4–2.0 grams of protein per kilogram of body weight per day to help improve workout effectiveness. For a 150-pound person who consumes 2000 calories per day, that would be roughly 95 to 136 grams of protein per day or 19% to 27% of daily calories.

Vegan diets may also provide fewer branched-chain amino acids (BCAAs), such as leucine, which are the building blocks of protein. Leucine is an amino acid utilised in muscle protein synthesis. Common sources of leucine include meat and dairy products, which are not consumed on a vegan diet. However, foods like brown rice, tofu, black beans, and peanut butter also contain leucine and are suitable for vegans.

It is important to note that diet quality matters most. A balanced macro vegan diet is likely far healthier than an omnivore diet limited to heavily processed foods. So, your vegan diet will be healthy if you choose high-quality foods.

High Protein Foods for Vegans

• Tofu and soy-based alternatives
• Grains: lentils, quinoa, seitan, amaranth, chickpeas
• Legumes: black beans, green beans, green peas
• Seeds: hemp seeds, pumpkin seeds, chia seeds
• Soy: tofu, edamame, tempeh
• Vegan protein powders

Fats: Keep saturated fats to under 10% of daily calories, but don't forget that fat is important for satiety and nutrient absorption

Fat is an essential part of a healthy and balanced diet. It is a macronutrient that provides our bodies with energy and supports many bodily functions. A moderate amount of fat in your diet can help you absorb vitamins A, D, E, and K, as well as regulate hormone levels and blood pressure.

There are different types of fats, and not all of them are healthy. Saturated fats, typically found in processed foods, dairy products, and meat, can lead to a build-up of cholesterol in the body when consumed in excess. This can clog blood vessels and increase the risk of heart disease. Trans fats, mostly found in hydrogenated vegetable oil, can also lead to high cholesterol levels.

Unsaturated fats are considered the 'healthy' fats. They can help lower cholesterol levels when used instead of saturated fats. There are two types of unsaturated fats: monounsaturated and polyunsaturated. Polyunsaturated fats typically contain omega fatty acids, which have various benefits, including skin nourishment and anti-inflammatory properties.

It is recommended that saturated fat intake be limited to less than 10% of daily calories. For a 2000-calorie diet, this would mean consuming less than 200 calories or 22 grams of saturated fat per day. However, it is important to note that not all saturated fats are equal. For example, coconut oil has a high saturated fat content, but it does not contribute to unhealthy cholesterol levels in the same way as animal-based sources.

To ensure a healthy balance of fats in a vegan diet, it is recommended to consume plant-based sources of unsaturated fats. Avocados, nuts, seeds, and olive oil are all examples of foods that provide healthy unsaturated fats. These foods can be easily incorporated into your favourite recipes or enjoyed as snacks.

While fat is essential, it is important to watch your fat intake if weight loss is your goal. Fat provides more than double the calories provided by carbohydrates or protein. Therefore, a diet higher in fat can easily become a diet higher in calories.

Fibre: Aim for 14g of fibre per 1000 calories as a minimum

Fibre is an essential part of a healthy diet. It is a non-digestible carbohydrate found in plant-based foods like legumes, whole grains, fruits, vegetables, and seeds. A diet high in fibre is associated with a reduced risk of heart disease, diabetes, obesity, colorectal cancer, and other gastrointestinal disorders.

The American Heart Association suggests consuming 28 grams of fibre daily, but studies show that very few people reach this target. When you choose a vegan diet, however, you will likely consume more fibre because it is found in plant-based foods.

If you are active and trying to lose weight, you must fuel your activity properly without creating too much of a calorie deficit. Vegans should eat about 50-75% of their fibre intake back as digestible carbohydrates. If you eat 50 grams of fibre daily, you need to eat 37.5 grams of digestible carbs to compensate for the indigestible carbs.

As a general rule, you should aim for a minimum of 14 grams of fibre per 1000 calories. For example, if you are consuming 2000 calories per day, this would mean a minimum of 28 grams of fibre. It is also important to establish an upper limit for yourself, as this will vary from person to person. Pay attention to your body's reactions and be fairly consistent with your fibre intake. Try to eat within a 10-gram range on most days.

Calories: Vegans have the same calorie requirements as non-vegans, but remember to account for fibre intake

Calorie requirements are dependent on a variety of factors, including age, sex, weight, height, and activity levels. For example, a sedentary person will require fewer calories than an athlete. However, vegans have the same calorie requirements as non-vegans.

When it comes to calorie counting, it's important to remember that a calorie is a unit of energy. It is not a physical entity but a measure of the amount of energy in a particular food. One calorie is the amount of energy required to raise the temperature of one gram of water by one degree Celsius. In dietary terms, we usually refer to kilocalories, or 1000 calories.

When determining your daily calorie intake, it's important to take into account your goals. If you want to maintain your current weight, you need to consume your maintenance calories. If you want to gain weight, you need to eat more than your maintenance calories, and if you want to lose weight, you need to eat less.

When it comes to a vegan diet, it's important to remember that whole, plant-based foods tend to be nutrient-dense rather than calorie-dense. This means that you may need to eat larger volumes of food to meet your calorie goals. For example, if your maintenance calories are 2000, you will need to eat 2000 calories' worth of plant-based foods to stay at your current weight.

It's also important to remember that fiber intake is typically higher on a vegan diet. Fiber is a non-digestible carbohydrate found in plant-based foods like legumes, whole grains, fruits, vegetables, and seeds. While fiber has many health benefits, it can also impact the number of calories your body absorbs from food. This is because fiber passes through your digestive system relatively intact, meaning that some of the calories from fiber-rich foods are not absorbed. Therefore, when counting calories on a vegan diet, it's important to account for the fiber content of the foods you're consuming.
