Our philosophy

Data over dogma

There are too many gurus selling magic pills. As a Registered Sports Nutritionist and a practising karateka, I work from your energy systems, your training schedule and your physiology — not from whatever is trending this quarter.

Energy balance

Energy balance (CICO)

Start with thermodynamics. Whether the target is hypertrophy or making weight, we calculate TDEE and set a deficit or surplus you can actually hold.

Macronutrient ratios

Macronutrient ratios

Protein synthesis rates, glycogen replenishment windows, hormonal regulation. Protein, fat and carbohydrate set to fuel the session in front of you.

Evidence over hype

Evidence over hype

Every recommendation traces back to peer-reviewed literature — and when the literature is thin, you get told that too. Read the knowledge base.

Our expertise

Three ways to work together. All of them start with the same free call.

Fight camp & weight cutting

Avoid the flat legs and the dangerous cut. An 8–12 week plan built on chronic energy balance, glycogen and gut-content manipulation, and sodium protocols — for MMA, karate and other weight-category athletes.

  • Weekly check-ins through camp
  • Fight-week and rehydration protocol
  • ISAK body-composition tracking

Nutrition & fatigue diagnosis

Stuck at a plateau. Bring your training schedule, diet log and current supplements; 60 minutes of structured review against evidence-based standards to find what is actually limiting you.

  • 60-minute structured audit
  • Supplement review against WADA and third-party testing
  • Written summary of findings

Teams & corporate

From the ring to the meeting room: the science of energy management. A nutrition culture for professional squads; sedentary fatigue and burnout mitigation for executive teams.

What actually happens

No mystery, no sales sequence. Three steps from the first call to a protocol you are running.

  1. Discovery call — 15 minutes, free

    Your sport, your calendar, your constraints. You leave knowing whether nutrition is your limiting factor, and whether I am the right person for it. If the answer is no, I say so.

  2. Assessment

    Diet log, training load, current supplementation and — where relevant — ISAK anthropometric profiling and available biomarkers. This is the part that decides everything after it.

  3. Protocol & review

    A periodised plan written against your actual week, then scheduled reviews that adjust it as the block progresses. Plans that survive contact with real training are the only ones worth writing.

In their words

Athlete and client outcomes are being collected for publication here, with consent. In the meantime, the press coverage and the knowledge base are the public record of the work.

Common questions

What is sports nutrition? 什麼是運動營養學?

Sports nutrition focuses on fueling your body for optimal athletic performance and recovery.

運動營養學的核心在於透過精確的營養攝取,為身體提供能量以優化運動表現並加速修復。

What types of athletes do you work with? 您的服務對象有哪些?

I specialize in evidence-based nutrition plans for combat sports athletes, weight-category competitors, executives and anyone pursuing peak performance.

我專注於為格鬥運動員、體重分級選手、高管以及追求卓越表現的人士,提供以科學實證為基礎的營養規劃。

Why choose evidence-based sports nutrition? 為什麼選擇科學實證營養?

It ensures advice is based on scientific research, leading to safer and more effective strategies.

科學實證營養學確保指導建立在嚴謹科研之上,能提供更安全且具實質成效的競賽策略。

What can I expect from a consultation? 諮詢過程包含什麼?

We'll discuss your goals and current diet to develop a personalized nutrition plan.

在諮詢中,我們將全面評估您的運動目標與飲食習慣,並以此定制個人化方案。

How does data play a role? 數據在計劃中扮演什麼角色?

I use dietary habits and biomarker tests for a data-driven, precise approach.

我透過分析飲食習慣及潛在的生物標記數據,以數據驅動模式確保訓練成果精準高效。

What is the safest way to cut weight for combat sports? 格鬥運動員最安全的降體重(Weight Cut)方法是什麼?

The safest method involves a structured, evidence-based approach focusing on chronic energy balance and acute water manipulation. At KHPN, we avoid extreme dehydration and instead utilize scientific strategies like glycogen depletion, gut content manipulation, and precise sodium protocols to ensure athletes make weight without compromising their fight performance or health.

最安全的方法是採用循證醫學的結構化策略,專注於長期的熱量平衡與短期的水分調控。在 KHPN,我們拒絕極端脫水,而是運用肝醣消耗、腸道內容物排空及精確的鈉攝取方案等科學方法,確保運動員在不損害戰鬥表現與健康的前提下順利過磅。

How far in advance should I start a weight management plan for a fight? 我應該在比賽前多久開始執行體重管理計畫?

For optimal results and minimal performance decrement, a chronic weight management plan should begin 8 to 12 weeks before the weigh-in. This allows for a gradual reduction in body fat while maintaining lean muscle mass, leaving only a small, safe percentage of body weight to be manipulated during the acute fight week phase.

為了達到最佳效果並將運動表現的衰退降至最低,長期的體重管理計畫應在過磅前 8 到 12 週開始。這允許運動員在維持肌肉量的同時逐漸減少體脂,使得在賽前一週的急性降重階段只需處理一小部分且安全的體重比例。

Why do elite athletes need a Supplement Audit? 為什麼菁英運動員需要進行「營養補充品審查 (Supplement Audit)」?

Athletes are strictly liable for any prohibited substance found in their system. A Supplement Audit minimizes the risk of unintentional anti-doping rule violations (ADRV) by systematically reviewing current supplementation against WADA guidelines, verifying third-party testing (e.g., Informed Sport), and eliminating redundant or cross-contaminated products.

運動員必須對其體內發現的任何違禁物質承擔嚴格責任。補充品審查透過對照 WADA(世界反禁藥組織)指南系統性地評估現有的營養補充品,驗證第三方測試認證(如 Informed Sport),並排除多餘或有交叉污染風險的產品,從而將無意間違反反禁藥規定 (ADRV) 的風險降至最低。

Are all third-party certified sports supplements safe to use? 所有獲得第三方認證的運動補充品都是安全且有效的嗎?

While third-party certifications like Informed Sport significantly reduce the risk of contamination, they do not guarantee efficacy or correct dosing for your specific sport. A professional audit ensures that the supplements are not only clean but also evidence-based and physiologically relevant to your specific training block and energy systems.

雖然像 Informed Sport 這樣的第三方認證能大幅降低產品受污染的風險,但它們無法保證該產品對您所從事的特定運動是有效且劑量正確的。專業的補充品審查不僅能確保補充品的純淨度,更能確認其具備循證依據,且在生理學上符合您當前的訓練週期與能量系統需求。
