Nutritional Guide & Macro Tracking - Eat Smarter

Macronutrients 101

Every calorie you eat comes from one of three macronutrients. Understanding them changes how you eat forever.

💪 Protein

4 calories per gram

What it does: Builds and repairs muscle, supports immune function, creates enzymes and hormones.

Daily target:

Sedentary adults: 0.36g per lb of body weight
Active adults: 0.6–0.8g per lb
Athletes / muscle building: 0.8–1.2g per lb
Weight loss: 0.8–1g per lb (higher protein preserves muscle)

Best sources:

Chicken breast: 31g per 100g
Salmon: 25g per 100g
Eggs: 6g per egg
Greek yogurt: 17g per cup
Lentils: 18g per cooked cup
Tofu: 20g per cup
Ground beef (lean): 26g per 100g

Key insight: Protein is the hardest macro to overeat and the most filling. Prioritize it first when building meals.

⚡ Carbohydrates

4 calories per gram

What it does: Primary energy source for brain and muscles. Fuels exercise and daily activity.

Daily target:

Sedentary: 45–55% of total calories
Active: 50–60% of total calories
Low-carb approach: 20–40% of total calories
Keto: under 5–10% of total calories

Best sources (complex carbs):

Brown rice: 45g per cooked cup
Sweet potatoes: 27g per medium potato
Oats: 27g per half cup (dry)
Quinoa: 39g per cooked cup
Whole wheat bread: 13g per slice
Fruits: 15–30g per serving
Beans: 40g per cooked cup

Key insight: Choose complex carbs over simple. They digest slower, keep you full longer, and prevent energy crashes.

🥑 Fats

9 calories per gram

What it does: Absorbs vitamins (A, D, E, K), builds cell membranes, produces hormones, provides sustained energy.

Daily target:

General: 20–35% of total calories
Minimum healthy: ~0.3g per lb of body weight
Going below 20% can disrupt hormones

Best sources (healthy fats):

Avocado: 21g per avocado
Olive oil: 14g per tablespoon
Nuts (almonds): 14g per ounce
Salmon: 13g per 100g (omega-3s!)
Eggs: 5g per egg
Chia seeds: 9g per 2 tbsp
Dark chocolate: 9g per ounce

Key insight: Fats are calorie-dense (9 cal/g vs 4 cal/g for protein/carbs). A little goes a long way. Measure oils and nuts.

Calorie Fundamentals

Calories determine whether you gain, lose, or maintain weight. Everything else is details.

🔥 Maintenance Calories (TDEE)

The number of calories you burn per day doing nothing + activity. Eating at maintenance = same weight.

Quick estimate:

Sedentary: body weight (lbs) × 13–14
Lightly active: body weight × 14–15
Active: body weight × 15–17
Very active: body weight × 17–19

Example: 160 lb moderately active person: 160 × 15 = ~2,400 calories/day

📉 Weight Loss

Eat fewer calories than you burn. A deficit of 500 cal/day = ~1 lb loss per week.

Mild deficit: 250 cal/day (0.5 lb/week)
Moderate deficit: 500 cal/day (1 lb/week)
Aggressive deficit: 750–1000 cal/day (1.5–2 lb/week)

Important: Don't go below 1,200 cal (women) or 1,500 cal (men) without medical supervision. High protein during a deficit preserves muscle.

📈 Muscle Building

Eat more calories than you burn. A surplus of 200–300 cal/day for lean gains.

Lean bulk: maintenance + 200–300 cal/day
Standard bulk: maintenance + 300–500 cal/day
Protein: 0.8–1.2g per lb body weight

Important: Resistance training is required for muscle growth. Extra calories without exercise = just fat gain.

The Balanced Plate Method

Don't want to count every calorie? Use the plate method instead. Visual, simple, effective.

🟢 Half the Plate: Vegetables & Fruits

Fill half your plate with non-starchy vegetables and some fruit.

Leafy greens (spinach, kale, lettuce)
Broccoli, cauliflower, Brussels sprouts
Peppers, tomatoes, cucumbers
Berries, apples, citrus (smaller portion)

Why: Low calorie, high fiber, loaded with vitamins. Makes you feel full without adding calories.

🔴 Quarter of the Plate: Protein

Dedicate one quarter to a quality protein source.

Chicken, turkey, fish, lean beef
Eggs (2–3)
Tofu, tempeh, beans
Greek yogurt, cottage cheese

Why: Protein builds muscle, keeps you full, and has the highest thermic effect (burns calories to digest).

🟡 Quarter of the Plate: Complex Carbs

Use one quarter for starchy carbohydrates and grains.

Brown rice, quinoa, whole wheat pasta
Sweet potatoes, regular potatoes
Whole grain bread
Oats, barley

Why: Provides sustained energy. Complex carbs digest slowly and prevent blood sugar spikes.

🟠 Drizzle: Healthy Fats

Add a small amount of healthy fat to complete the meal.

1 tbsp olive oil (for cooking or dressing)
Quarter avocado
Small handful of nuts
Cheese (thumb-sized portion)

Why: Absorbs fat-soluble vitamins, adds flavor and satiety. Keep portions controlled (fats are 9 cal/g).

Essential Micronutrients

Vitamins and minerals you need daily. Most people are deficient in at least one.

Vitamin D

Need: 600–1000 IU daily

Sources: Sunlight, fatty fish, eggs, fortified milk

Most people: Deficient. Supplement 1000–2000 IU in winter.

Magnesium

Need: 400–420mg (men), 310–320mg (women)

Sources: Nuts, seeds, leafy greens, dark chocolate, beans

Most people: Below target. Eat more nuts and greens.

Iron

Need: 8mg (men), 18mg (women pre-menopause)

Sources: Red meat, lentils, spinach, fortified cereals

Tip: Pair with vitamin C for better absorption.

Potassium

Need: 2,600–3,400mg daily

Sources: Bananas, potatoes, beans, avocado, spinach

Most people: Way below target. Eat more produce.

Calcium

Need: 1,000mg daily

Sources: Dairy, fortified plant milk, tofu, kale

Tip: Vitamin D helps calcium absorption. Take together.

Fiber

Need: 25–38g daily

Sources: Beans, oats, berries, whole grains, vegetables

Most people: Eat half the recommended amount. Add gradually.

Omega-3 Fatty Acids

Need: 250–500mg EPA+DHA daily

Sources: Fatty fish (salmon, sardines), walnuts, flax seeds

Tip: Eat fish 2× per week or take algae supplement.

Zinc

Need: 11mg (men), 8mg (women)

Sources: Oysters, beef, pumpkin seeds, chickpeas, cashews

Tip: Vegetarians may need 50% more due to lower absorption.

Macro Tracking Tips

📱 Track for 2 Weeks, Then Estimate

Use an app (Cronometer, MyFitnessPal) for 2 weeks to learn portion sizes. After that, you can estimate without tracking. Most people develop an intuitive sense quickly.

🥩 Prioritize Protein First

Plan your protein at each meal first. It's the hardest macro to hit and the most important for body composition. Then fill in carbs and fats around it.

⚖️ Use a Food Scale (at First)

Weigh your food for 1–2 weeks. You'll be surprised how much 6 oz of chicken actually is (or isn't). This calibrates your eyes permanently.

🍽️ Don't Obsess Over Exact Numbers

Within 10% is good enough. If your protein target is 150g, hitting 135–165g is fine. Consistency over precision.

📊 Track Weekly Averages

One high-calorie day doesn't matter if the weekly average is on target. Look at 7-day trends, not daily fluctuations.

🧂 Don't Forget Hidden Calories

Cooking oil (120 cal/tbsp), sauces (50–100 cal/serving), and drinks (juice, coffee creamer) add up fast. Track everything for accurate results.

🥗 Build Repeatable Meals

Create 5–7 meals you know the macros for. Rotate them. You only need to track new meals. This saves enormous time.

💧 Hydration Matters Too

Water isn't a macro but affects everything. Aim for 8–12 cups daily. More if active. Dehydration mimics hunger and kills performance.
