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
Start with serving size
Look at protein, carbs, and fat
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.
