what are macronutrients

What are macronutrients? You've surely heard of them before, but what exactly are macronutrients and micronutrients?

In short, they are the keys to achieving optimal health, wellness, and a better overall quality of life for you and your family.

But don't worry if you don't know a lot about them; you are not alone!

Knowing more about protein, carbohydrates, dietary fat, vitamins, and minerals, and how much of each to consume, can maximize your energy and overall health.

So, what are macronutrients and micronutrients? Here's everything you need to know about protein, carbs, fat, vitamins, minerals, and more!

Are these 20 nutrient-dense foods in your meal plan?

What are Macronutrients?

The three macronutrients include those your body requires daily to maintain optimal health, wellness, energy, and metabolism.

Essential macronutrients include:

  • Protein
  • Carbohydrates
  • Dietary fat

Many foods contain a healthy balance of all three macronutrients, or at least two of the three.

Consuming the right amount of protein, carbohydrates, and dietary fat, and knowing how to properly incorporate these macronutrients into your diet, helps you meet weight management and fitness goals.

These might include weight loss, fat loss, healthy weight maintenance, or muscle building.

Healthy Carbohydrates

Carbohydrates give you energy and help you maintain numerous essential body functions.

The Institute of Medicine recommends getting about 45-65% of your daily calories from carbohydrates, or at least 130 grams of carbohydrates daily for adults.

Many specialized diets, such as ketogenic, Atkins, and other low-carb diets, contain fewer than 45% of their calories from carbohydrates.

Finding the right balance of carbohydrates, protein, and fat is the best way to optimize energy levels, especially if you work out regularly.

Examples of healthy carbs to consider include:

Starchy Vegetables

Starchy vegetables are loaded with fiber, vitamins, and minerals.

Healthy carbs keep you full for longer time periods to help you gain long-lasting energy.

Examples of starchy vegetables that contain about 15 grams of carbohydrates per serving include:

  • Sweet potatoes
  • Corn
  • Peas
  • Black beans
  • Kidney beans
  • Navy beans
  • Lentils
  • Garbanzo beans

As a rule, fill about one-fourth of your plate with starchy vegetables or whole grains to make sure you're meeting daily starch requirements without overindulging in carbs.

Non-Starchy Vegetables

Many non-starchy vegetables contain about 5 grams of carbohydrates per serving and fewer calories than starchy vegetables.

While non-starchy veggies might not give you long-lasting energy associated with starchy vegetables, they can still fill you up and are loaded with fiber, vitamins, and minerals.

Examples of nutritious non-starchy veggies include:

  • Leafy greens
  • Cucumbers
  • Tomatoes
  • Broccoli
  • Cauliflower
  • Zucchini
  • Squash
  • Mushrooms
  • Asparagus
  • Bell peppers
  • Celery
  • Onions

When planning healthy meals and menus, aim to fill about half of each plate with non-starchy vegetables if you can.

Whole Grains

Whole-grains are fiber-rich starches that can keep you full for hours.

Examples of whole-grain, healthy carbohydrates that provide about 15 grams of carbohydrates per serving include:

  • Brown rice
  • Wild rice
  • Oatmeal
  • Whole-grain cereal
  • Whole-grain bread
  • Quinoa
  • Whole-grain pasta
  • Whole-grain couscous

As a rule, choose whole grains over refined grains (such as white rice and white bread) whenever possible.

Fill about one-fourth of each plate with whole grains or starchy vegetables.

Here are the most important carbs to avoid for weight loss!



Fruits are rich in simple carbohydrates, meaning they give you a quick boost of energy.

Fruits are packed with fiber, vitamins, and minerals, and provide about 15 grams of carbohydrates in each serving.


  • Watermelon, cantaloupe, or honeydew melon
  • Blueberries, strawberries, blackberries, raspberries, or cherries
  • Bananas, apples, pears, peaches, or grapes
  • Oranges, grapefruit, or tangerines
  • Kiwi fruit

Aim to eat about 1-2 servings of fruit per day, depending on your total daily calorie needs.

Milk Products

Milk usually contains about 12 grams of carbohydrates in each 1-cup portion.

However, some high-protein milks contain fewer carbohydrates.

Yogurt and kefir are also sources of carbohydrates.

Make sure to choose milk products without added sugar whenever possible.

Greek yogurt usually contains fewer carbohydrates (about 5 grams) compared with regular yogurt.

Check the ingredient label on milk products if you're counting carbohydrates, as the carb content of dairy foods can vary widely.

Nuts and Seeds

Nuts and seeds are high in dietary fat, but also contain protein and a small number of carbohydrates (usually about 5 grams of carbs per serving).

Consider peanuts, almonds, walnuts, pistachios, pumpkin seeds, sunflower seeds, or nut butters to meet your daily macronutrient needs.

Nutritious Protein Foods

Protein is a key nutrient that's beneficial for numerous reasons.

Protein helps you build and maintain strong muscles and bones, boosts your metabolism, increases satiety, and helps you maintain a healthy weight.

Some high-protein foods are also rich in carbohydrates, while others aren't. Examples of nutritious protein foods to consider are:

Meat, Poultry, and Seafood

Protein-rich meat, poultry, and seafood usually contain about 20-25 grams of protein per serving.

Examples include:

  • Lean organic steak, bison, and venison
  • Chicken, turkey, and duck
  • Salmon, tuna, and other types of fish
  • Shrimp, scallops, crab, and other seafood

As a rule, aim to fill about one-fourth of each plate of food with nutritious meats, poultry, fish, seafood, meat substitutes, or eggs.


Eggs and egg whites are also good sources of high-quality protein, containing about 6 grams of protein per whole egg or about 7 grams in each serving of two egg whites.

Eggs don't provide a significant amount of carbohydrates, but egg yolks contain about 5 grams of dietary fat.

Plant-Based Meat Substitutes

If you're following a vegetarian diet or simply enjoy meat substitutes every now and then, consider the following protein-rich plant foods (containing about 10-20 grams of protein per serving):

  • Tofu
  • Tempeh
  • Miso
  • Seitan
  • Mycoprotein meat substitutes
  • Veggie burgers

While plant-based meat substitutes may not offer quite as much protein as meat itself, these foods are still an excellent source of protein, vitamins, and minerals.

Milk Products

Milk and products made from milk are good sources of protein and calcium, often containing about 8-28 grams of protein in each 1-cup portion.

Many milk products are also sources of carbohydrates. Examples of nutritious, protein-rich dairy foods to consider include:

  • Low-fat milk
  • Plain Greek yogurt
  • Low-fat cottage cheese
  • Plain kefir
  • Reduced-fat cheese

Aim to consume about 2-3 servings of milk products (or plant-based, calcium-rich alternatives), each day to optimize your health.

Protein Powder

Protein powder usually provides about 20-25 grams of protein in each 1-scoop portion.

Protein powder might contain soy, eggs, whey, casein, pea, hemp, rice, other plant-based proteins, or combinations of these high-protein ingredients.

Many types of protein powders are low in carbohydrates and dietary fat, but check the ingredient label to know for sure.

Legumes are packed with carbohydrates, including dietary fiber, and protein.

They often provide about 15 grams of protein in each 1-cup portion, as well as 15 grams of fiber and 40 grams of total carbohydrates.

Examples of healthy legumes to consider include:

  • Pinto beans
  • Black beans
  • Kidney beans
  • Navy beans
  • Lentils
  • Chickpeas
  • Green peas

Because legumes are high in carbohydrates, count them as starches when filling up your plate.

Aim to fill about one-fourth of your plate with legumes, other starchy vegetables, or whole grains.

Nuts and Seeds

Nuts and seeds are rich in protein in addition to heart-healthy fats and fiber.

Many nuts and seeds offer about 7 grams of protein, 14 grams of dietary fat, and 5 grams of carbohydrates in each serving.

Consider adding peanuts, pumpkin seeds, sunflower seeds, almonds, pistachios, other nuts or seeds, or nut butters to healthy meal plans.

Healthy Fats

Dietary fat is a macronutrient that's just as important as carbohydrates and protein.

Fat is crucial for properly absorbing certain vitamins, achieving optimal brain function, and maintaining healthy hair, skin, and nails.

Fat is a source of energy that helps you feel full for longer time periods.

Many popular weight-loss diets, including ketogenic diets, are rich in heart-healthy dietary fats.

Consider adding the following fats to daily meal plans:

  • Avocados
  • Nuts
  • Seeds
  • Nut butters
  • Olive oil
  • Coconut oil
  • Other plant-based oils
  • Coconuts
  • Olives
  • Hummus

The Institute of Medicine recommends adults consume 20-35% of their daily calories from dietary fat.

This equates to about 40-70 grams daily if you're following a 1,800-calorie meal plan.

Check the nutrition facts label or use an online nutrition database to evaluate fat grams.

At around 40, most women's hormone levels begin a “rollercoaster' ride, which eventually culminates in menopause. You feel tired all the time. It's hard to lose weight. Your body doesn't respond to diet and exercise like it used to. But now, it doesn't have to be that way for you…

What are Micronutrients?

Micronutrients, which include vitamins and minerals, are just as important as macronutrients when it comes to achieving optimal health and wellness.

Vitamins and minerals are crucial for maintaining high energy, and essential functions and structures within the body.

Vitamins and minerals work together with macronutrients to keep you healthy and reduce the risk of serious health problems.


Vitamins are found in virtually all nutritious, whole foods.

Essential vitamins include:

  • Vitamin A
  • Vitamin C
  • Vitamin D
  • Vitamin E
  • Vitamin K
  • Vitamin B1 (thiamine)
  • Vitamin B2 (riboflavin)
  • Vitamin B3 (niacin)
  • Vitamin B5 (pantothenic acid)
  • Vitamin B6
  • Vitamin B7 (biotin)
  • Vitamin B12
  • Folate

Eat a variety of fruits, vegetables, legumes, whole grains, dairy foods, other protein-rich foods, and heart-healthy fats to meet daily vitamin requirements.

Ask your doctor if taking a multivitamin supplement is right for you, to reduce your risk of developing a vitamin deficiency and side effects associated with it.


Like vitamins, your body needs essential minerals on a daily basis to function properly and reduce the risk of health problems.

For example, calcium is a mineral that's crucial for bone health, heart health, and maintaining strong teeth.

Essential minerals include:

  • Calcium
  • Phosphorous
  • Magnesium
  • Iron
  • Manganese
  • Copper
  • Iodine
  • Zinc
  • Molybdenum
  • Sodium
  • Potassium
  • Chloride
  • Fluoride
  • Selenium

Most multivitamin supplements contain essential minerals in addition to vitamins.

Make sure to read supplement facts on multivitamin supplements to make sure they meet your daily requirements.

After a simple blood test, your doctor can let you know if certain vitamin or mineral levels are low.
