For individuals seeking dietary flexibility without restrictive guidelines, the "If It Fits Your Macros" (IIFYM) approach can be a suitable option. This guide explores how to calculate your macros on a plant-based diet, offering insights into the principles, benefits, and potential drawbacks of this approach.
Understanding IIFYM and Macronutrients
IIFYM, or “If It Fits Your Macros,” provides a flexible dieting method where weight management is achieved by tracking macronutrients rather than strictly counting calories. This approach was developed by fitness enthusiast Anthony Collova, offering a less restrictive alternative to traditional dieting. Macronutrients, or macros, are the four types of food molecules the body uses for energy. In IIFYM, three macronutrients are primarily tracked:
- Protein: Contains 4 calories per gram.
- Carbohydrates: Contains 4 calories per gram.
- Fat: Contains 9 calories per gram.
Alcohol, a fourth macronutrient with 7 calories per gram, is typically not included in IIFYM calculations.
Implementing the IIFYM Diet
The IIFYM diet involves a few key steps:
- Calculating Your Macros: Determine the grams of protein, carbs, and fat needed daily to meet your weight goals.
- Meeting Your Macros: Track and adjust food intake to stay within your daily macro targets.
IIFYM is versatile, suitable for both weight loss and weight gain, depending on calorie adjustments.

Calculating Your Macros: A Step-by-Step Guide
- Basal Metabolic Rate (BMR): Calculate your BMR, which is the number of calories your body burns at rest.
- Adjust for Activity Level: Multiply your BMR by an activity factor to account for your daily activity level, resulting in your Total Daily Energy Expenditure (TDEE).
- Adjust Based on Weight Goals:
- For weight loss, reduce your calorie intake by 15-25%.
- For weight gain, increase your calorie intake by 5-15%.
- Determine Your Macros:
- Protein: Aim for 0.7-1.0 grams per pound of body weight.
- Fat: Aim for 0.25-0.4 grams per pound of body weight.
- Carbohydrates: Allocate the remaining calories to carbohydrates.
For weight loss, prioritize reducing calories and increasing protein to preserve lean muscle mass while losing body fat. The final IIFYM plan will provide your daily targets for calories, protein, fat, and carbohydrates.
Tracking Your Food Intake
Tracking your food intake is crucial for determining whether you are meeting your macros. Several tools can assist with this:
- MyFitnessPal
- My Macros+
- Lose It!
- Cronometer
Using a digital scale to weigh your food in grams is recommended for accurate macronutrient calculations. While precise tracking is beneficial, minor deviations (within 5 grams over or 10 grams under for each macronutrient) are acceptable.
Macronutrient Sources: A Plant-Based Perspective
Understanding which foods are rich in each macronutrient is essential.
- Foods High in Protein:
- Legumes (beans, lentils, peanuts, peas, soy)
- Nuts
- Quinoa
- Soy products (Tofu, Tempeh, Seitan)
- Foods High in Fats:
- Avocado
- Nuts and nut butters
- Oils from fruits, nuts, and seeds
- Olives
- Seeds (chia, flax, hemp, sesame, pumpkin)
- Dark Chocolate
- Foods High in Carbs:
- Breads, cereals, pastas, and baked goods
- Legumes
- Grains (oats, wheat, barley, rye, rice)
- Fruits (bananas, plantains, mangoes, apples, berries)
- Pseudocereals (amaranth, buckwheat, millet, quinoa, teff, wild rice)
- Starchy vegetables (potatoes, sweet potatoes, winter squash, corn)
- Root Vegetables (carrots, beets)
Balancing Macros on a Vegan Diet
A well-rounded vegan diet incorporates a variety of protein sources like legumes, soy products, grains, nuts, and seeds to meet all amino acid requirements. To maintain energy balance, it’s important to evaluate the calories you consume versus those you expend. Use online calculators to determine your individual macronutrient needs based on factors like weight, height, age, and activity level. Adjust your intake ratios to align with your specific health goals, whether it's weight loss or muscle gain.

Benefits of the IIFYM Diet
The IIFYM diet offers several advantages:
- Educational Experience: It enhances understanding of the macronutrient composition of foods.
- Achieving Weight Goals: By reducing or increasing calories as needed, IIFYM supports weight loss or gain.
- No Forbidden Foods: All foods are permissible within macro limits, promoting balance and reducing dietary guilt.
- Flexibility and Adherence: IIFYM allows meal planning around your lifestyle, making it easier to stick to long-term.
IIFYM is adaptable to various dietary preferences, including vegan, vegetarian, paleo, and gluten-free diets.
Potential Downsides of the IIFYM Diet
Despite its benefits, IIFYM has some drawbacks:
- It's Still a Diet: Like all diets, long-term success can be challenging, with many people regaining lost weight.
- Emphasis on Macronutrients: The focus on macros can overshadow the importance of micronutrients (vitamins and minerals).
- Health Conditions: IIFYM may not be suitable for individuals with health conditions requiring specific dietary restrictions.
- Risk of Disordered Eating: Tracking macros can potentially trigger disordered eating behaviors in some individuals.
It's essential to ensure adequate micronutrient intake and seek guidance from a dietitian or healthcare professional when needed.
Maximizing Nutrition on a Plant-Based IIFYM Diet
Prioritize whole, unprocessed foods to maximize nutrient intake and reduce the risk of chronic diseases. Incorporate legumes, tofu, and seitan for high-quality protein, whole grains and starchy vegetables for carbohydrates, and healthy fats from nuts, seeds, plant-based oils, and avocados.

Strategic Supplementation
Guaranteeing ideal nutrition on a vegan diet often hinges on the strategic use of supplementation and fortified foods. Fortified foods play an essential role in meeting your nutrient needs, particularly for calcium, vitamin D, and vitamin B12. Regularly incorporating fortified foods into your meals guarantees you meet your micronutrient needs.
Sample Meal Plan Ideas
- Breakfast: Proatmeal (protein powder added to oatmeal), protein coffee (coffee blended with MCT oil and/or vanilla protein powder).
- Lunch: Stir fry with sauteed veggies, seitan, and seasonings.
- Dinner: Tofu stir-fry with your favorite veggies, or black bean tacos topped with avocado and salsa.
- Snacks: Roasted chickpeas, hemp seed energy balls.
Practical Tips for Success
- Weigh Your Food: Regularly use a food scale to accurately measure portion sizes.
- Plan Your Meals: Plan your daily meals in advance to ensure you meet your macro targets.
- Be Consistent: Consistent tracking is crucial, especially in the beginning.
- Prioritize Whole Foods: Focus on consuming 80% of your calories from whole foods, including 4-6 servings of fruits and vegetables daily.
- Stay Hydrated: Drink plenty of fluids, targeting 6 to 8 cups daily. Proper hydration supports overall health and can help with nutrient absorption.
- Adjust Your Macros: If you eat a plant-based diet, there’s nothing wrong with eating less protein and more fats and carbohydrates so you can focus on meeting your protein needs with whole foods.
A Macro Cheat Sheet for Vegans
- Protein: Legumes and beans (7-20g protein per serving), soy products (11-20g protein per serving), quinoa (4g protein per 100g), oats (10g protein per 100g), chia and hemp seeds (2-5g protein per serving).
