40/30/30 Macros: A Comprehensive Guide to the Classic Macro Split

30th August 2023

The 40/30/30 macros refer to a specific ratio of macronutrients – 40% carbohydrates, 30% protein, and 30% fats. This balanced macro split has become one of the most well-known and recommended approaches for those looking to build muscle, lose fat, or simply eat healthier.

The term “macros” refers to macronutrients – the main nutrients that provide calories, including protein, carbs, and fat. Tracking macros involves paying attention to the grams of each that you eat per day, rather than just overall calories.

While the 40/30/30 macros have been popularized by bodybuilders and fitness models seeking a lean, muscular physique, this macro ratio can also be utilized by regular gym-goers and individuals looking to lose weight, gain energy, or improve health. When combined with exercise, these macros provide a great nutritional framework without needing to strictly count every calorie.

In this comprehensive guide, we’ll break down everything you need to know to successfully implement the 40/30/30 macros, including:

• The history and origins of the 40/30/30 macro ratio
• How to calculate your calorie and macro needs
• Which foods to eat and avoid for each macronutrient
• Sample meal plans and recipes based on the macros
• The benefits of 40/30/30 for health, fitness, and body composition
• Tips for sustainability and customizing the macros to your needs

Ready to master the 40/30/30 macros? Let’s dive in.

A Brief History of the 40/30/30 Macros

While it’s unclear who originally came up with the exact 40/30/30 macro split, the general practice of tracking macros has been around since at least the 1970s. During this decade, bodybuilders began carefully tracking their intake of protein, carbs, and fat with the goal of fueling muscle gains while keeping body fat low.

The 40/30/30 ratio itself was popularized in the fitness community by legendary bodybuilder Ronnie Coleman in the 1990s. Coleman advocated these macros to support intense weight training and building his famously hulking, muscular physique.

The macros gained mainstream popularity in the early 2000s when Dr. Barry Sears utilized a 40/30/30 split in his famous Zone Diet. While the Zone Diet was originally developed for heart health and weight loss, the macro ratio aligned well with fitness goals too. Books by Dr. Sears brought the 40/30/30 split into public consciousness.

Since then, these macros have become a mainstay of pop culture fitness, referenced by celebrities, athletes, trainers, and nutrition gurus. They remain one of the most well-known and sustainable macro splits for achieving body composition goals.

Calculating Your Calorie and Macronutrient Needs

To follow the 40/30/30 macros correctly, you’ll first need to calculate your total daily calorie needs along with the grams of protein, carbs, and fat that will make up those calories. This requires factoring in variables like your:

• Gender
• Age
• Height/weight
• Activity level
• Goals (maintain, lose fat, gain muscle etc)

Luckily, there are many macro calculators available online that simplify this process. You input your stats and goal, and they provide your total calorie needs plus the gram amounts of each macro to hit the 40/30/30 ratio.

For example, a 30-year-old male who is 6’0, 180 pounds, lifts 4x a week and wants to maintain his weight/physique would need around 2,700 calories per day, broken down into:

• 270g protein (1080 calories)
• 135g fat (1215 calories)
• 337g carbs (1350 calories)

This provides the optimal fuel and macronutrients to support his training while keeping his current body composition.

If your goal is fat loss, reduce total calories while keeping the macro ratio the same. For muscle gain, increase total calories with more calories from protein. The calculator adjusts your macros accordingly. Re-calculate every 4-6 weeks as your stats and goals change.

Choosing the Best Carb Sources

Carbs make up 40% of calories on the 40/30/30 macros, so it’s crucial to choose nutritious sources to fuel workouts and recovery. Some top choices include:

• Whole grains – Brown rice, oats, quinoa, whole grain pasta
• Starchy vegetables – Potatoes, sweet potatoes, peas, winter squash
• Legumes – Lentils, beans, chickpeas
• Fruits – Berries, apples, bananas, citrus fruits
• Low-fat dairy – Milk, yogurt, cottage cheese

Opt for less processed carbs when possible, like steel-cut oats instead of instant. Limit refined carbs like chips, baked goods, and sugary drinks. Time your carb intake strategically around workouts to maximize performance and recovery.

Choosing the Right Protein Sources

Protein makes up 30% of calories in the 40/30/30 macros. Getting enough high-quality protein helps build and preserve metabolically active muscle mass when combined with strength training.

Some excellent protein sources to rotate include:

• Lean meats – Chicken, turkey, 93% lean beef, pork
• Fish – Salmon, cod, tuna, shrimp
• Eggs and egg whites
• Greek yogurt
• Protein powders – Whey, casein, plant-based

Whey protein is ideal for before/after workouts due to its quick absorption. Casein digests slower, making it a good nighttime protein source. Spread out protein intake over 3-5 meals per day.

Selecting the Best Fat Sources

Don’t fear fats – they play an essential role in health and hormones. But focus on unsaturated fats from whole food sources like:

• Avocados
• Nuts and seeds
• Olive oil
• Full-fat salad dressings
• Fatty fish like salmon and mackerel
• Whole eggs
• Full-fat Greek yogurt

Limit intake of processed foods containing trans and hydrogenated fats. Pay attention to the source and type of fat rather than fearing the amount.
