Muscle Is Your Retirement Account. Protein Helps Fund It.
Stronger muscles. Better appetite control. More stable energy. A body built to keep doing life.
When most people hear the word protein, they immediately think about bodybuilding.
Chicken breasts. Protein shakes. Guys carrying gallon jugs around the gym.
But protein is about so much more than building bigger muscles.
Protein plays a role in your muscles, recovery, appetite, metabolism, brain function, hormones, enzymes, immune system and your ability to stay strong and independent as you age.
And for many of the adults we work with at Results By Design Fitness, one of the simplest nutrition improvements they can make is this:
Eat more protein.
Not an extreme amount.
Not a bodybuilder diet.
Just enough, consistently.
For many active women, around 100 grams of protein per day can be an excellent practical target.
It isn’t a magic number and everyone’s needs are different, but 100 grams gives us a simple goal that is easy to understand, track and build meals around.
Protein Helps You Feel FULL
This might be one of protein’s biggest advantages.
Have you ever eaten a bowl of cereal, a muffin or a couple pieces of toast for breakfast…
…and felt hungry again two hours later?
Compare that with eating eggs and Greek yogurt.
Same person.
Same morning.
Very different experience.
Protein tends to be highly satiating, meaning it helps your body recognize:
“I’ve eaten. I’m satisfied.”
A systematic review and meta-analysis published in Physiology & Behavior looked at randomized controlled trials examining protein and appetite. Researchers found that higher protein intake acutely decreased hunger and desire to eat while increasing fullness and satiety. Protein also influenced appetite-regulating hormones, including reductions in ghrelin and increases in GLP-1 and CCK.
In other words:
Protein doesn’t just give you calories.
It helps those calories stick with you.
That can make it much easier to walk past the snack cabinet at 3:00 PM without feeling like something inside you is screaming:
FIND CHOCOLATE IMMEDIATELY. 😂
Protein Can Help Create a More Stable Blood-Sugar Response
We don’t like saying that one food magically “balances blood sugar,” because human physiology is more complicated than that.
But protein can absolutely change how your body responds to a meal.
A 2024 systematic review and meta-analysis found that adding protein to carbohydrate-containing meals generally reduced the post-meal glucose response in people without diabetes, although the response varied depending on protein source, dose and metabolic health.
Think about the difference between:
Toast by itself
versus:
Eggs + toast + berries
Or:
A banana by itself
versus:
Greek yogurt + banana + walnuts
Or:
Rice by itself
versus:
Chicken + rice + vegetables
Protein changes the composition of the meal.
And instead of living on meals and snacks dominated by rapidly digested carbohydrates, you now have a meal containing protein, fiber, carbohydrates and often some healthy fat.
For many people, that translates into steadier energy, greater satisfaction and fewer “I need something sweet RIGHT NOW” moments.
Protein Can Help Reduce Cravings Because You’re Actually Fed
Sometimes we treat every craving like a discipline problem.
It isn’t always.
Sometimes you’re simply underfed.
If breakfast is coffee and toast…
Lunch is a tiny salad…
And by 4:00 PM you’ve eaten 25 grams of protein all day…
You may not have a motivation problem.
Your body may simply be asking for FOOD.
Research has found that higher-protein eating patterns can improve fullness and appetite control. One controlled study found a higher-protein diet reduced hunger, desire to eat and even fast-food cravings while increasing fullness compared with normal-protein diets.
That’s why getting protein in early and consistently throughout the day can be such a game changer.
Instead of trying to “be good” all day and then fighting hunger all evening…
Feed your body.
Your Brain Needs Amino Acids Too
Here’s an area people rarely associate with protein.
Your brain.
When you digest protein, your body breaks it down into amino acids.
Those amino acids aren’t only used for muscle.
Certain amino acids also serve as precursors used by the body to produce important neurotransmitters.
For example:
Tryptophan → serotonin
Tyrosine → dopamine and norepinephrine
Research has long demonstrated that changes in blood levels of these amino acids can influence their availability to the brain and the synthesis of neurotransmitters.
That doesn’t mean eating another chicken breast instantly raises your dopamine or fixes your mood.
Brain chemistry is far more complicated than that.
But it does reinforce an important point:
Protein is not merely “gym food.”
Protein supplies building materials used throughout the entire body—including the nervous system.
And Then There Is Muscle
This is the big one for us at RxD.
Muscle changes how you experience life.
Muscle helps you get off the floor.
Carry groceries.
Pick up your grandkids.
Travel.
Hike.
Garden.
Golf.
Play pickleball.
Carry luggage through an airport.
Get out of a chair without pushing off the armrests.
Catch yourself when you stumble.
Keep living independently.
Muscle isn’t just something you see in the mirror.
Muscle is physical freedom.
Resistance training provides the stimulus telling your body:
“We need this muscle.”
Protein provides the amino acids your body needs to maintain, repair and build that tissue.
A large systematic review and meta-analysis published in 2022 concluded that increasing daily protein intake can produce additional gains in lean body mass and lower-body strength when combined with resistance exercise.
That combination matters.
Strength training + adequate protein.
Not one or the other.
Both.
Ladies: Protein Will NOT Make You Bulky
We still hear this one all the time.
“I don’t want to eat too much protein because I don’t want to get bulky.”
Ladies…
It simply doesn’t work that way.
Building large amounts of muscle is actually very difficult and typically requires years of intentional progressive resistance training, sufficient calories and the genetics to support it.
What most women are actually describing when they say they want to look “toned” is:
More muscle + less body fat.
Protein can help support that process by helping you preserve and build lean tissue while improving satiety.
Research specifically in women performing resistance training has also found that higher protein intake can support increases in fat-free mass rather than suddenly producing an unwanted “bulky” appearance.
You aren’t accidentally going to wake up looking like a competitive bodybuilder because you ate Greek yogurt and chicken yesterday.
😂
What you may notice over time is:
Stronger arms.
Stronger legs.
Better body composition.
More definition.
Greater physical capability.
That’s a pretty good trade.
So What Does 100 Grams of Protein Actually Look Like?
This is where people are often surprised.
Because 100 grams sounds like A LOT.
Until you spread it across the day.
Here is a very realistic example.
BREAKFAST — Approximately 25g
3 eggs + Greek yogurt + berries
Eggs provide quality protein.
Greek yogurt gives you another easy protein source.
Fruit gives you carbohydrates, fiber and micronutrients.
You’re already roughly one-quarter of the way to your goal before leaving the house.
LUNCH — Approximately 30g
Grilled chicken + rice + vegetables
Nothing fancy.
Nothing magical.
Chicken.
Rice.
Vegetables.
Real food.
About 30 grams of protein.
Running total:
55g
AFTERNOON SHAKE — Approximately 20g
One simple protein shake
Now you’re at:
75g.
And this is where we absolutely believe liquid nutrition has a place.
Protein shakes are:
Fast.
Convenient.
Portable.
Easy after training.
Great when life gets busy.
But here’s the distinction:
Supplements should supplement your diet.
They shouldn’t become your diet.
Interestingly, research comparing solid and liquefied high-protein meals found that the solid protein meal suppressed hunger more strongly than the liquid version.
So use the shake when it makes your life easier.
But let whole food dominate your nutrition.
DINNER — Approximately 25g
Salmon + quinoa or potato + vegetables
Another 25 grams.
And suddenly:
100 GRAMS.
No extreme diet.
No six chicken breasts.
No four protein shakes.
No eating out of Tupperware containers every two hours.
Just:
25g + 30g + 20g + 25g = 100g
That is completely doable.
Let Whole Foods Dominate
One of our favorite ways to simplify nutrition is to stop making it complicated.
Build most of your meals around foods that your great-grandmother would have recognized as food.
Foods you could have:
Hunted.
Fished for.
Gathered from the ground.
Picked from a tree.
Think:
Eggs.
Chicken.
Beef.
Fish.
Greek yogurt.
Cottage cheese.
Beans.
Lentils.
Potatoes.
Rice.
Fruit.
Vegetables.
Nuts.
Seeds.
Those foods should make up the foundation.
Then we can use modern convenience foods strategically.
Protein powder?
Absolutely.
A shake after training?
Great.
A protein bar when you’re traveling?
Fine.
But we don’t want someone drinking breakfast, drinking lunch and surviving on packaged “health foods.”
Whole food first.
Supplements for convenience.
That’s a sustainable nutrition strategy.
Stop Trying to Eat Less. Start Trying to Eat BETTER.
This is one of the biggest mindset shifts we want people to make.
So much of dieting is built around restriction:
Don’t eat this.
Cut that out.
Eat less.
Skip breakfast.
Avoid carbs.
Don’t snack.
And eventually people are hungry, frustrated and wondering why nutrition feels impossible.
Instead, start with a positive target.
Ask:
“Where is my protein?”
Breakfast?
Get protein.
Lunch?
Get protein.
Dinner?
Get protein.
Need help getting there?
Use a shake.
Suddenly you’re not spending the entire day thinking about all the foods you’re “not allowed” to eat.
You’re focused on giving your body what it needs.
And something interesting often happens:
When you consistently eat enough protein and real food, there’s simply less room—and often less desire—for everything else.
Is 100 Grams Right for Everyone?
No.
There isn’t one protein number that is perfect for every human being.
Your needs depend on factors including:
Body size
Age
Activity level
Training
Health status
Calorie intake
Goals
Someone who weighs 110 pounds and walks several days per week may need something different than a 180-pound woman strength training four days per week.
So don’t think of 100 grams as a prescription.
Think of it as a practical starting point that works extremely well for many active adults—and particularly many women who previously might only be eating 40–60 grams per day.
If you have kidney disease or another medical condition requiring protein restriction, your intake should be individualized with your physician or registered dietitian.
