💪 WHAT HAPPENS TO YOUR MUSCLE WHEN YOU DON’T EAT ENOUGH CARBS?
Here’s where things get interesting.
Your muscles store carbohydrate as glycogen. When you exercise—especially during higher-intensity strength training, intervals, running, or longer workouts—your muscles draw on that stored glycogen for fuel.
When carbohydrate intake is consistently too low, glycogen stores can become depleted.
That doesn’t mean your body immediately “eats your muscles.” But if you’re also not eating enough total calories or enough protein, your body has a harder time supporting muscle repair and recovery. During an energy deficit, muscle protein can be broken down for energy, particularly when the deficit is severe. (ACSM)
You may notice:
• Less energy during workouts
• Reduced strength or endurance
• Fatigue coming on sooner
• Poorer recovery
• Less training volume
• Difficulty maintaining or building muscle
Carbohydrates help you train. Protein helps repair and build.
You need both. 🏋️♀️🍚
👵 AND THIS IS ESPECIALLY IMPORTANT AS WE AGE
This is something we see frequently with older adults.
As we get older, we generally need fewer calories—but more attention to nutrient quality and protein. The National Institute on Aging emphasizes that older adults need nutrient-dense foods because they often have fewer calories to work with. (NIA)
One common pattern we see is a meal that becomes heavily carbohydrate-based:
🥣 Cereal
🍞 Toast
🍪 Crackers
🍚 Rice
🥔 Potatoes
There’s nothing wrong with these foods.
The problem is when the carbohydrate takes up most of the meal and the protein gets left behind.
As we age, maintaining muscle becomes increasingly important. Protein provides the amino acids needed to repair and maintain muscle, and older adults may need more protein than younger adults. ACSM resources suggest roughly 1.0–1.2 g/kg/day for healthy older adults, with higher needs possible for people who are exercising regularly or dealing with illness. (ACSM)
So instead of:
❌ Big bowl of cereal + little protein
Think:
✅ Greek yogurt + berries + oats
Instead of:
❌ Toast + fruit
Think:
✅ Eggs + whole-grain toast + fruit
Instead of:
❌ Large serving of rice + small amount of chicken
Think:
✅ A solid portion of chicken + vegetables + an appropriate portion of rice
🍗 THINK OF YOUR PLATE AS A TEAM
PROTEIN = building & repair
CARBOHYDRATES = fuel
FATS = hormones, cell function & energy
FRUITS & VEGETABLES = vitamins, minerals & fiber
You don’t have to eliminate carbs to lose weight.
And you don’t need to eat unlimited carbs because they’re “healthy.”
You need balance.
For older adults especially, the goal should be to protect muscle while providing enough carbohydrate to support movement and activity.
Because the goal isn’t simply to weigh less.
It’s to be strong enough to carry the groceries, climb the stairs, get off the floor, travel, play with your grandchildren, and remain independent.
💙 CARBS ARE FUEL.
PROTEIN IS BUILDING MATERIAL.
YOUR BODY NEEDS BOTH.
