How to Optimize Athletic Performance Through Metabolism

How to Optimize Athletic Performance Through Metabolism

TL;DR

Athletes need high metabolic rate for performance. PUFAs suppress thyroid and increase inflammation—both kill performance. Optimize metabolism first: eliminate PUFAs, adequate carbs, quality protein, saturated fats. Then train. Recovery improves. Strength increases. Endurance builds. Performance peaks.


You're training harder than ever.

Five days per week. Six days. Pushing limits. Tracking macros. Taking supplements.

Your performance plateaued. Or declined. You're slower. Weaker. Can't recover.

You thought more training was the answer. It's not.

Your metabolism is broken.

Athletic performance is like a race car. Training is the driver. Metabolism is the engine. The best driver can't win with a broken engine.


Metabolism Determines Performance Capacity

High metabolic rate:

Low metabolic rate:

You can't out-train bad metabolism.

How PUFAs Kill Athletic Performance

They suppress thyroid. Low T3 means low energy production. Mitochondria can't make ATP efficiently. Power output drops.

They cause inflammation. Chronic inflammation impairs recovery. Muscles stay sore longer. Joints hurt. Performance declines.

They damage mitochondria. PUFAs oxidize in mitochondrial membranes. Energy production slows. Endurance suffers.

They impair protein synthesis. Damaged gut from PUFAs reduces protein absorption. Muscle growth slows despite adequate protein intake.

They lower testosterone. Men: reduced power and strength. Women: reduced performance and increased injury risk.

What Elite Athletes Did (Before Seed Oils)

Traditional athletes ate:

  • Meat, eggs, dairy
  • Potatoes, rice, fruit
  • Butter, lard, tallow
  • No seed oils

Their performance:

  • Olympic records from 1950s-1970s still stand
  • Strength athletes were massive and powerful
  • Endurance athletes recovered faster

Modern athletes:

Result: More injuries. Slower recovery. Need more supplements to compensate.

How to Eat for Performance

Eliminate seed oils completely. Every restaurant meal, every packaged snack contains them. Cook all food yourself.

Eat adequate carbohydrates.

Protein:

  • 1.6-2.2g per kg body weight for strength/muscle building
  • 1.2-1.6g per kg for endurance
  • From meat, eggs, dairy, fish (not powders mixed with seed oils)

Fats:

  • Butter, coconut oil, ghee
  • Animal fats from meat
  • Egg yolks
  • 20-30% of calories

Salt liberally. Athletes lose sodium through sweat. Replace it.

Meal timing:

Training With Optimized Metabolism

Recovery improves:

  • Soreness reduces
  • Sleep quality increases
  • Muscles rebuild faster
  • Fewer injuries

Performance increases:

  • More power output
  • Better endurance
  • Improved focus
  • Faster times/higher weights

Hormones optimize:

Less is more: With optimized metabolism, training quality improves. Need less volume. Get better results.

What About Supplements

Unnecessary if metabolism is optimized:

  • Pre-workout (just need food)
  • BCAAs (complete protein is better)
  • Most commercial recovery drinks (contain seed oils)

Potentially helpful:

Fix diet first. Supplements are 5% max.

Endurance vs. Strength

Endurance athletes: Need even more carbs (5-7g per kg body weight). Chronic cardio suppresses thyroid. Mitigate with:

Strength athletes: Build muscle better with:

Both need optimized metabolism.

Recovery Markers to Track

Temperature: Should stay 98°F+ even during hard training. If drops, reduce volume or increase food.

Pulse: Should be 75-85 at rest. Above 90 = overtraining. Below 70 = suppressed metabolism.

Sleep: Fall asleep easily. Sleep through night. Wake refreshed. If not, reduce training or address metabolism.

Appetite: Should be hungry. Good sign. Eat to satiety. If appetite disappears, you're overtrained.

Mood: Stable, positive. If irritable or depressed, check recovery.

FAQ

Q: Do I need to carb-load before competition? A: If your glycogen stores are full from eating adequate daily carbs, you don't need special carb-loading. Eat normal high-carb meals 2-3 days before event.

Q: What about protein timing (anabolic window)? A: Total daily protein matters more than timing. But eating protein within 1-2 hours post-training optimizes muscle protein synthesis. Don't stress about 30-minute windows.

Q: Can I build muscle on this approach? A: Yes. High protein, adequate carbs for training, progressive overload. Many athletes build muscle faster once metabolism is optimized.

Q: What if my sport requires weight class? A: Optimize metabolism first at normal weight. Then cut weight strategically (final 2-3 weeks). Don't chronically restrict to maintain weight class—kills metabolism and performance.
