Understanding your numbers is the first step toward food freedom. It’s not about restriction; it’s about functional fueling. Use the tools below to find your baseline and start treating your nutrition like the powerhouse resource it is!

Not Sure What Your Activity Level Is?

This factor plays a huge role in determining your daily caloric baseline! Use the guide below to pick what best represents your life.

Sedentary: Little to no exercise; desk job; minimal daily movement

Light: Light exercise or sports 1–3 days/week; or a job with lots of walking.

Moderate: Moderate exercise/sports 3–5 days/week; active “on your feet” job.

High: Hard exercise or sports 6–7 days a week; physically demanding job.Athlete: Very hard exercise/sports daily & physical job or 2x/day training.

Expert Tip: Most women who work out 3x a week but spend the rest of the day “on their feet” (mom-life, retail, nursing, etc.) often fall into the “Moderately Active” category rather than “Lightly Active.”

What’s a Macro?

While calories determine the quantity of energy you take in, macronutrients (protein, carbohydrates, and fats) determine the quality of your body composition and how you feel. Think of calories as the gas in your car, but macros as the oil, the coolant, and the structural frame that keeps everything running smoothly.

  • Protein (The Builder): Protein is essential for repairing muscle tissue, supporting bone health, and keeping you full. Especially for active women, hitting your protein target is the key to seeing “tone” and strength gains from your workouts.
  • Carbohydrates (The Battery): Carbohydrates are your body’s preferred source of fast-acting energy. They fuel your brain and your high-intensity workouts. Don’t fear them; embrace them as the “spark” that allows you to train hard and recover well.
  • Fats (The Regulator): Healthy fats are vital for hormone production, brain health, and the absorption of key vitamins. They provide a slow-burning energy source and are crucial for maintaining a healthy nervous system and hormonal health and balance.

Eating the appropriate amount of protein, carbs, and fat within your calorie budget is not only essential to hitting your fitness goals, but also helps you to feel your best overall!

How to Use Your Results: From Data to Daily Life

You have your numbers…now what? Calculations are a powerful compass, but the magic happens in the execution. Here is how to take these results and turn them into a lifestyle that sticks.

1. The “Two-Week Baseline” Test

Don’t jump into a massive deficit or surplus on day one. Start by eating at your calculated Maintenance level for two weeks. This allows your metabolism to stabilize and gives you a true “baseline” to see how your body responds to consistent fueling before you make any aggressive changes.

2. Prioritize Protein

If you used the $0.99 Macro Calculator, you now have a protein goal. If you change nothing else, focus on hitting that protein target first. Protein is the building block for muscle recovery and the secret weapon for staying full and satisfied throughout a busy day.

3. Monitor Your Biofeedback

The math of the Mifflin-St Jeor equation is highly accurate, but it can’t see your stress levels, your sleep quality, or your hormonal cycle. If you are hitting your numbers but feel exhausted, constantly hungry, or aren’t seeing recovery, it’s a sign we need to adjust your “fueling map.”

Still Feeling Overwhelmed? Let’s Do the Heavy Lifting Together.

Numbers on a screen are a great start, but they don’t account for the reality of your life; the late-night cravings, the “busy-mom” schedules, or the plateau that just won’t budge.

If you’re tired of “guesstimating” and want a nutrition strategy that is as unique as your DNA, my One-on-One Nutrition Coaching is for you. We move beyond the calculator to look at your hormones, your habits, and your specific goals to build a plan that feels like second nature, not a chore.

Stop guessing and start thriving.

Let’s turn these numbers into a sustainable, results-driven plan tailored specifically to you.

Energy Balance 101: Understanding the “Why” Behind the Numbers

To master your nutrition, you need to understand the three pillars of how your body uses energy.

The Three Pillars of Energy:

  1. BMR (Basal Metabolic Rate): This is the energy your body needs just to stay alive (breathing, heart beating, brain functioning) if you were to lay in bed all day. Think of this as your “idling” speed.
  2. NEAT (Non-Exercise Activity Thermogenesis): This is the energy used for everything we do that isn’t sleeping, eating, or sports-like exercise. Walking to the car, folding laundry, fidgeting, and standing. For most women, NEAT is a massive contributor to total burn!
  3. EAT (Exercise Activity Thermogenesis): The calories you burn during your intentional workouts.

The TDEE Equation: When we add these together (plus the energy it takes to digest your food), we get your TDEE (Total Daily Energy Expenditure). This is the total number of calories your body burns in a 24-hour period.

The Math of Body Composition:

  • Caloric Deficit: Consuming fewer calories than your TDEE. Your body taps into stored energy (fat) to bridge the gap, resulting in weight loss.
  • Caloric Maintenance: Consuming exactly what you burn. Your weight stays stable.
  • Caloric Surplus: Consuming more than your TDEE. Your body stores the extra energy. When paired with functional strength training, this is the “sweet spot” for building muscle.

The Fitness Cult Philosophy: While the math is simple, the human part is complex. Hormones, sleep quality, and stress levels all impact these numbers. Use these calculations as a map, but always listen to your body’s biofeedback (energy levels, hunger, and mood).

Numbers are Just the Beginning. Let’s Build a Plan.

Knowing your number is one thing; knowing how to hit it with a toddler hanging off your leg is another! Whether you are breastfeeding, training for your first 500-mile year, or just trying to feel energized again, I’m here to help. My nutrition coaching takes the guesswork out of fueling so you can focus on thriving, not just calculating.
