carbs • water • sodium • potassium • magnesium • biological reality
Most lifters today treat protein as gospel — as if its mere presence guarantees muscular growth.
But this is an error of isolated thinking. Protein does not operate in a vacuum.
Without the substrates that power training and recovery — carbohydrates, water, and sodium — protein cannot be effectively utilized. No fuel, no engine. No hydration, no contraction. No sodium, no cellular transport.
These aren't "tuning knobs" or supplemental tweaks for the advanced.
They are the base wiring of muscular performance and recovery — and their neglect is why most trainees spin their wheels year after year, wondering why progress has stalled despite high protein intake.
In this section, we'll dispense with dogma, and examine what your muscles actually require — not according to trends or marketing, but according to biology.
Everyone worships protein, but forgets muscles run on glycogen, not whey shakes.
Start with 3–5g carbs per kg bodyweight per day.
Adjust based on training output, digestion, and how "full" or flat your muscles feel over time.
Water isn't just about hydration — it's the solvent for every process of recovery, digestion, and performance.
0.7 to 1 oz per pound of bodyweight
Increase if you train intensely or live in hot climates
No real downside — unless you ignore electrolytes.
Most people err on the side of too little water, not too much. The body is highly efficient at regulating fluid balance — you'll excrete what you don't need.
But if you're drinking aggressively without replacing sodium, potassium, and magnesium, you're not hydrating — you're diluting. That's when performance and cognition decline.
Sodium isn't the enemy — it's the conductor of hydration and performance.
Let's make this concrete:
A pack of cheap Top Ramen may list 1600mg of sodium, but your body might only absorb 20–30% of that — if that.
Why?
Salt isn't inherently bad. Garbage food with unbalanced salt loads is.
You don't need to be neurotic about tracking milligrams — just don't fear salt, and stop outsourcing your performance to the worst forms of it.
Use it with purpose. Not as filler.
Rule of Thumb:
As a baseline: aim for 3000–5000mg of sodium per day if you train intensely — more if you sweat heavily or live in a hot climate.
This is not medical advice — this is metabolic common sense.
Sodium is only one part of the equation. Without its two co-factors — potassium and magnesium — the electrical system fails.
These minerals regulate the fluid exchange between cells, ensure proper muscle contraction, and prevent the dreaded flat, crampy, depleted feeling that lifters often blame on "low carbs" or "overtraining."
Most lifters eat plenty of salt — but nowhere near enough potassium.
The optimal ratio? Roughly 2:1 potassium to sodium.
Magnesium is the nervous system's brake pedal. You don't want to lift heavy with your foot off the brake.
Food | Serving | Magnesium (mg) | Calories |
---|---|---|---|
Oatmeal (cooked) | 1 cup | ~60 mg | ~150 kcal |
Baked potato (with skin) | 1 medium (173g) | ~45 mg | ~160 kcal |
Avocado | 1 cup (150g) | ~44 mg | ~240 kcal |
Whole wheat bread | 2 slices (60g) | ~45-50 mg | ~160 kcal |
Salmon (wild) | 3 oz (85g) | ~26 mg | ~175 kcal |
Greek yogurt | 6 oz (170g) | ~30-40 mg | ~100-120 kcal |
Dark chocolate (70-85%) | 1 oz (28g) | ~64 mg | ~170 kcal |
You don't need to eat like a rabbit to get your magnesium — but you do need to eat with intention.
These foods already fit in a balanced diet. Once you know what they offer, you can stop guessing and start targeting.
Bottom Line: If you're following a well-balanced diet — with whole food sources of carbohydrates, protein, and fats — you're likely getting 150–250mg of magnesium from food.
That's a solid base. Use supplements to fine-tune, not compensate for neglect.
A nightly 500mg magnesium glycinate capsule, for example, provides ~90mg elemental magnesium — and also supports sleep, anxiety regulation, and recovery.
It's not just a "mineral" — it's part of your system's braking mechanism.
🧠 300–400mg elemental magnesium for general health
💪 400–600mg elemental if you're training hard or under stress
These are not supplements — they are the substrate of performance itself.
Without them, protein is inert.
It does not build. It does not repair. It merely circulates, waiting for support that never comes.
Ignore this, and you are not under-eating protein.
You're under-thinking the entire biological process.
