MACROS 101: BASELINES

Updated: May 4


What we’re covering:


  • What macros actually are

  • The role of protein, carbs, and fats

  • Micronutrients, water, and alcohol

  • The 4-4-9 rule (how to read food labels)

  • MyFitnessPal basics (activity levels + setup)

  • How your goal impacts your nutrition

  • Where to start (habits first)

  • GLP's and when to get personalized support






Before we start

I’m a fitness nutrition specialist, not a registered dietitian.


That means:

  • I help you understand nutrition

  • I help you build structure and awareness

  • I help you apply it to real life


If you need:

  • A clinical diagnosis (ex: blood sugar)

  • A strict meal plan (I can create simple meal guides or point you toward meal prep options)

  • Or deeper medical or behavioral nutrition support


→ a registered dietitian/nutritionist is the best route


If you want clarity, structure, and a way to actually stick with it… you’re in the right place.


What are macros?

Macros = nutrients your body needs from the outside

  • Protein

  • Carbohydrates

  • Fats


What they do...

Protein → builds, repairs, keeps you full

Carbs → fuel (energy, workouts, brain)

Fats → balance (hormones, brain, health)


Micronutrients

Micronutrients are your vitamins, minerals, and electrolytes.


Examples:

  • Sodium

  • Potassium

  • Magnesium

  • Calcium

  • Natural sugars from whole foods


They don’t provide calories, but they are essential for:

  • Hydration balance

  • Muscle function

  • Energy production

  • Recovery


Water

Hydration impacts:

  • Energy

  • Digestion

  • Performance

  • Recovery


You can also “eat your water”:
  • Cucumbers

  • Lettuce

  • Berries

  • Citrus

  • Watermelon


Alcohol
  • 7 calories per gram

  • Not a macro, but still counts

  • Can impact fat loss, sleep, and recovery

  • Adds to water retention, belly fat and excess empty calories

  • Try to "keep it clear" and drink plenty of water


→ Awareness over restriction


My quick 4-4-9 reminder

I use this reference with clients on macro loads:

  • Protein = 4 calories per gram

  • Carbs = 4 calories per gram

  • Fat = 9 calories per gram


How to read a food label
  1. Start with serving size

  2. Look at protein, carbs, and fat

  3. Use 4-4-9 to understand the breakdown of macros

Food label examples

If a label shows "290 calories" 20g protein 30g carbs 10g fat you can estimate calories using 4-4-9: protein (20×4 = 80) carbs (30×4 = 120) fat (10×9 = 90) for a total of ~290 calories.

*If the label lists something slightly different, that’s normal. Food labels can round numbers and account for things like fiber and sugar alcohols.

*Also, be mindful of labels like “low fat” or “no fat” They often adjust carbs or sugars to make up for taste, so always look at the full macro breakdown, not just the claim on the front.


If you’re tracking (MyFitnessPal basics)

Activity levels

Sedentary

  • Desk job

  • Minimal movement

  • Little to no structured exercise

Lightly active

  • Some walking

  • 2–3 workouts per week

Moderately active

  • 3–5 workouts per week

  • Consistent daily movement

Very active

  • Intense training most days

  • Physical job or high-output lifestyle


→ Most people fall into lightly or moderately active


Simple macro baseline
  • 40% carbs

  • 30–40% protein

  • 20–30% fat


This is a starting point, not a rule.


Your goal determines your focus

Fat loss

  • Prioritize protein

  • Stay consistent

Muscle building

  • Prioritize protein + carbs

  • Fuel your training

Maintenance

  • Balanced approach

  • Focus on consistency


Reality check on the scale
  • Muscle is more dense than fat

  • As you build lean muscle, the scale may not drop the way you expect

→ That doesn’t mean it’s not working This is where having guidance matters.


Where my clients start

1. Water

Before anything else - MINIMUM half body weight in ounces to start


2. Protein

Especially protein at breakfast

This helps:

  • Regulate hunger

  • Improve energy

  • Set the tone for your day


Building simple structure into your day

You don’t need perfection, you need consistency:

  • Breakfast (start with protein)

  • Mid-morning snack

  • Lunch

  • Afternoon snack

  • Dinner


Optional focus points:

Pre-workout

  • Fuel (typically carbs + some protein)

Post-workout

  • Recovery (protein + carbs + hydration)

I have deeper guides on basics if you want to go further.


A quick note on GLP-1 medications

If you are using (or considering) GLP-1 medications or other injectable weight loss treatments:

  • These can significantly reduce appetite

  • They may change hunger cues and overall intake

    Because of this, it’s important to work with a qualified medical provider.

From a nutrition standpoint:

  • You still need adequate protein

  • You still need hydration

  • You still need intentional structure

This is not something to guess your way through.


What matters daily

Start with:

  • Protein daily

  • Hydration (drink + eat your water)

  • Balanced meals

  • Consistency over perfection


If you want this personalized

This is where I come in.

I help you:

  • Apply this to your real life

  • Adjust based on your body

  • Align your nutrition with your fitness goals


Final thought

This isn’t about tracking forever but long enough to build structure.

It’s about learning your body well enough that you don’t have to guess anymore.
