Case Studies

Five Real Engagements,
Documented Outcomes

These are real clients Chef Alexx has worked with, documented in the published book Secrets of a Private Performance Nutrition Chef. Names have been changed. The genetic variants, the protocols, the lab values, and the lived outcomes are not. Each case study shows what changed, why it changed, and how long it took.

Identifying details have been anonymized to protect client privacy. The clinical detail, the genetic profiles, and the measured results are presented as they appeared in client engagements and in the published case record.

Case Study 01 Inflammation & Recovery

The Hyperimmune Couple

The Client

Married couple in their late forties. Both with histories of viral illness — one with shingles and lingering nerve pain, the other with mononucleosis and persistent fatigue. Both classified as hyperimmune responders on standard inflammatory panels.

The Challenge

Standard anti-inflammatory protocols had stalled. Diet logs looked correct on paper. Their bodies were treating ordinary stress as a threat and staying in a low-grade defensive state around the clock.

What the Genetics Revealed

Elevated baseline expression of inflammatory cytokine genes including IL-6 and TNF-alpha. Slow methylation clearance reducing the body's ability to regulate the inflammatory response after activation.

The Intervention

A six-month rebuild of the kitchen around polyphenol density, gentle cooking methods, removal of foods that were quietly amplifying their cytokine response, and methylation support sequenced before any high-intensity training returned.

Documented Outcomes

  • Husband: nerve flare frequency reduced approximately 70 percent
  • Wife: hs-CRP dropped from 4.1 to 0.7 mg/L
  • IL-6 normalized into the optimal range for both
  • Both reported sustained energy through the workday for the first time in years
"They stopped feeling like their own bodies were working against them."

Case Study 02 Cognitive Performance & MTHFR

The Actress Preparing for a $100 Million Production

The Client

Lead actress on a major film production. Fourteen-hour shooting days. The career, the team, the discipline were all in place. Persistent afternoon brain fog was making it harder to hold lines on camera.

The Challenge

Energy bars between scenes, fortified breakfast cereals, a standard multivitamin. Everything she had been doing right for years was making her core problem worse, because no one had identified the variant driving it.

What the Genetics Revealed

MTHFR C677T homozygous, meaning methylation was running at roughly thirty percent capacity. COMT and MAOA variants slowing dopamine clearance. APOE4 amplifying neuroinflammation under sustained stress.

The Intervention

Removed synthetic folic acid from the kitchen entirely. Rebuilt around naturally occurring folate from gently prepared greens, eggs, and legumes. Added methylfolate and methylcobalamin in divided doses. Morning protocol built for dopamine support, evening protocol built for serotonin and recovery.

Documented Outcomes

  • Processing speed up 34 percent over six months
  • Working memory up 28 percent
  • Sustained attention across long shoot days up 45 percent
  • Her director and co-stars noticed the change before her labs did
"She told me she had forgotten what clarity felt like. She had not realized she had been living without it."

Case Study 03 Executive Performance

The Fortune 500 CEO Running on Borrowed Energy

The Client

Chief executive of a multibillion-dollar company. Composed, disciplined, high-functioning. Decision fatigue arriving earlier in the day than it used to. Sleep degrading. Labs starting to flag.

The Challenge

He was not failing. He was slipping just enough to matter, on a system that had been running on caffeine and momentum for years. The cost of the next decade at this rate was not acceptable to him.

What the Genetics Revealed

COMT Val/Met slowing prefrontal neurotransmitter clearance. 5-HTTLPR short/short delaying the return to baseline after stress activation. APOE3/4 raising long-term neuroinflammatory risk. FTO amplifying cortisol-driven fat storage during high-pressure cycles. MTHFR C677T heterozygous reducing overnight recovery.

The Intervention

Strategic caffeine instead of reflexive caffeine. One cup before ten in the morning, paired with L-theanine, nothing after. Magnesium glycinate and phosphatidylserine in the evening to restore the neurological downshift into deep sleep. A Mediterranean-ketogenic hybrid framework. Protein-first sequencing at every meal to blunt the cortisol-driven insulin response.

Documented Outcomes

  • Decision-making speed up 28 percent in complex problem-solving
  • HbA1c dropped from 6.1 to 5.4 percent — out of pre-diabetic range
  • Blood pressure normalized from 145/92 to 128/78 without medication
  • CRP dropped from 4.8 to 1.2 mg/L
  • Cortisol curve normalized for the first time on record
  • Maintained executive performance on 15 percent fewer working hours
"He told me he used to finish the day feeling like he had survived it. Now he finishes it feeling like he ran it."

Case Study 04 Multi-System Reset & CBS/SUOX

The Senior Manager Whose 'Healthy Food' Was Making Her Sick

The Client

Senior corporate manager. Five years of specialist visits. Approximately fifty thousand dollars spent. Bloodwork that said normal while her body said anything but. Fatigue, digestive disruption, IBS flares, and reactions to food she could not pin down.

The Challenge

She had been doing everything right. Eggs, broccoli, kale, garlic, onions — the foods on every anti-inflammatory and gut-healing list in existence. And it was making her worse, because no one had identified the variant combination that turned those exact foods into a daily metabolic burden.

What the Genetics Revealed

MTHFR compound heterozygous. COMT and MAOA variants. MTR and MTRR dysfunction. CBS C699T pushing sulfur compounds through faster than the system could process. SUOX G.1456A reducing capacity to clear the sulfites that result. Three impaired systems compounding each other.

The Intervention

A three-phase, twelve-month protocol. Phase one removed the obstruction — high-sulfur foods restricted, molybdenum added to support sulfite clearance, synthetic folic acid eliminated. Phase two restored function with NAC and riboflavin. Phase three systematically rebuilt the diet around her improved processing capacity.

Documented Outcomes

  • Homocysteine dropped from 18.7 to 7.2 micromoles per liter
  • CRP dropped from 4.2 to 0.9 mg/L
  • IBS symptoms eliminated
  • 28 pounds of healthy weight loss without caloric restriction
  • Deep sleep increased from 45 minutes to 2.5 hours nightly
  • Promoted to Vice President eight months into the protocol
"Five years of medical specialists could not solve what genetic testing and personalized nutrition accomplished in twelve months. She went from barely functioning to thriving in every area of her life."

Case Study 05 Elite Athletic Recovery

The NFL Defensive Lineman, Year Twelve

The Client

Thirty-two-year-old NFL defensive lineman. Six foot four, two hundred eighty-five pounds. Twelve years in the league. Recovery time between practices was lengthening. Soft tissue injuries were accumulating. His wife told him he was running out of seasons.

The Challenge

Standard sports nutrition was not enough at this stage of a career. His genetic profile was working against him in ways nobody on the team had mapped, and the inflammatory cost of professional football was no longer something his body could clear on its own.

What the Genetics Revealed

IL-6 GG and elevated TNF-alpha expression amplifying every inflammatory event. COL5A1 TT variant affecting connective tissue resilience. ACTN3 R/R supporting power output but offering no recovery advantage. MTHFR C677T heterozygous slowing overnight repair.

The Intervention

An anti-inflammatory architecture built around game-week and recovery-week rotations. Polyphenol-dense whole foods at every meal. Targeted collagen and glycine support for connective tissue. Methylation cofactors timed for overnight repair. Specific elimination of foods that were quietly amplifying his cytokine load.

Documented Outcomes

  • CRP dropped 74 percent — from 8.2 to 2.1 mg/L
  • Creatine kinase reduced 65 percent — true muscle damage recovery
  • Heart rate variability up 35 percent
  • Reported soreness dropped from 8 out of 10 to 3 out of 10
  • Fourth-quarter power output up 15 percent
  • Soft tissue injuries reduced 60 percent
  • Zero missed practices across the protocol period
"His wife told him she had her husband back. That is the line that stayed with me."
