MVNI / FAST is a proposal—not an active long-term fast—to study, under medical and institutional oversight, how a defined formulation containing all nine essential amino acids affects lean tissue, cognition, strength, task performance, and safety during prolonged severe energy restriction.
Qualified investigators must determine whether any version is scientifically, medically, ethically, and institutionally defensible.
Founder-developed concept
No principal investigator or institutional sponsor
Not submitted to or approved by an IRB
No recruitment or intervention
Status updated August 4, 2026. Independent scientific, medical, regulatory, and institutional review remains pending.
HELP SHAPE THE NEXT STEP
Help determine whether—and how—the hypothesis should be studied.
We are asking qualified people to challenge the science, identify safety problems, contribute capability, or point us to the right investigator or institution. This is not recruitment or a request for endorsement.
The body carries fuel. The question is what it costs to use it.
When conventional food is absent, the body can draw heavily on stored fat and ketones—but protein loss does not fall to zero, and different kinds of performance may deteriorate at different rates. FAST asks whether supplying all nine essential amino acids could reduce—not eliminate—that cost, and where lean-tissue preservation, function, or safety begins to fail.
That is a testable hypothesis, not an established result. Fasting already increases reliance on stored fat; the proposal does not assume that amino acids increase fat oxidation. It asks what they change, what they fail to preserve, and which needs—including energy, essential fats, micronutrients, hydration, and whole-body physiology—they cannot replace.
A terminology correction matters: branched-chain amino acids are three members of the larger essential-amino-acid group. The proposed research must test a defined formulation and cannot assume that BCAAs alone reproduce meat, complete protein, or an adequate diet.
Build the scientific and medical team that can determine whether—and how—the idea can be tested safely.
The immediate goal is not endorsement. It is a rigorous feasibility review: define the safest informative next step, identify what must be redesigned, and determine whether a qualified investigator and institution should take the project forward.

THE CENTRAL HYPOTHESIS
Can stored fat supply most energy while a defined EAA formulation reduces the cost to lean tissue and function?
FAST proposes to characterize the trajectory of fuel use, whole-body nitrogen or protein-turnover measures, hydration-controlled body composition, selected functions, adherence, recovery, and safety during prolonged severe energy restriction.
Candidate primary aim for qualified review: determine whether a medically governed, prespecified protocol can generate interpretable feasibility, safety, adherence, and measurement data. Without a comparator or repeated conditions, a one-direction single-participant design cannot isolate an EAA treatment effect.
THE PROPOSED OUTCOMES
What changes when conventional food is absent but a defined EAA formulation is supplied?
The outcomes of interest include substrate-use estimates, investigator-selected nitrogen-balance or protein-turnover methods, hydration-controlled body composition, strength, cognition, operational performance, clinical safety markers, adherence, and recovery.
01
Fuel and preservation
How extensively does the body rely on endogenous fat, how much lean tissue and usable strength are retained or lost, and do functional changes emerge before body-composition changes?
Conceptual editorial illustration; not an active study procedure or documented partnership.
02
Function
How do cognition, judgment, movement, endurance, and task performance change when resupply is uncertain and mistakes have operational consequences?
Conceptual editorial illustration; no space-agency relationship is implied.
03
Safety
What renal, electrolyte, cardiovascular, endocrine, metabolic, cognitive, and refeeding risks appear—and what findings require an immediate stop?
Conceptual editorial illustration; not a depiction of a current participant.
04
Measurement
Which tests are repeatable enough to distinguish a real physiological or performance signal from learning effects, ordinary variation, and measurement noise?
Conceptual editorial illustration; methods remain subject to investigator selection.
INTERVENTION SPECIFICATION STILL REQUIRED
“Essential amino acids” is not yet a reproducible intervention.
A qualified investigator, research dietitian, medical owner, regulatory office, and institution would need to lock each item before formal review or activation.
Composition
All amino acids, exact ratios, ingredient source, flavoring, excipients, and metabolizable energy.
Dose and timing
Amount per dose, administration schedule, daily total, duration, and recovery or refeeding period.
Everything else consumed
Allowed fluids, electrolytes, micronutrients, medications, supplements, caffeine, and any rescue nutrition.
Product control
Certificate of analysis, purity, contaminants, lot identity, storage, stability, dispensing, and accountability.
Comparator and baseline
Repeated baseline, measurement-validation phase, comparator strategy, training controls, and learning-effect controls.
Measurement caution: urinary nitrogen can contribute to whole-body nitrogen accounting, but during EAA exposure it cannot by itself distinguish oxidation of ingested amino acids from endogenous tissue-protein loss. Any stronger claim requires investigator-selected methodology, potentially including stable-isotope methods.
REAL-WORLD RELEVANCE
Questions built for the moments when resupply fails.
These are potential future application areas—not proof of effectiveness, operational doctrine, or evidence of a military or aerospace partnership.
01
DISRUPTED SUPPLY LINES
Military, survival, and escape-and-evasion contingencies
If personnel are isolated, moving on foot, or cut off from normal provisions, every unit of carried weight matters. Could a compact, precisely documented amino-acid formulation preserve any meaningful amount of lean tissue, decision quality, or useful performance while conventional food is absent?
A defensible answer would require qualified operational researchers, independent medical authority, realistic task testing, and strict stopping rules. This website does not recommend attempting that scenario.
02
AEROSPACE CONTINGENCY
When a crew cannot be resupplied on schedule
Spaceflight magnifies constraints on mass, storage, shelf stability, waste, and resupply. Could a compact essential-amino-acid strategy buy useful time for lean-tissue retention or task performance during an emergency shortage—and what critical nutritional needs would remain unsolved?
That question is exploratory. It does not imply involvement, endorsement, or validation by NASA, any space agency, or any aerospace organization.
No implied affiliation: Art of Survival and this proposal are not affiliated with or endorsed by any military service, government agency, space agency, university, or prospective partner unless a relationship is explicitly documented.
Why these contexts are credible: NASA identifies nutrition, shelf life, mass, volume, and resupply as constraints for long-duration missions. The U.S. Army Research Institute of Environmental Medicine studies military feeding, rations, supplements, resilience, and performance under operational stress. These sources establish the relevance of the questions—not the efficacy of the proposed strategy or any relationship with Art of Survival. NASA nutrition-risk overviewUSARIEM research divisions
WHY SOMEONE OUTSIDE A LAB MIGHT CARE
Food scarcity can become a human-performance problem.
If the concept proves scientifically defensible, later research could inform questions relevant to disrupted supply lines, remote or austere operations, disaster response, maritime or aerospace contingencies, and military survival or evasion scenarios where weight, food access, decision-making, and physical capability matter.
A single-participant feasibility study could not establish operational doctrine or prove broad effectiveness. Its value would be narrower: expose safety problems, test measurement systems, refine the hypothesis, and determine whether larger controlled research is justified.
FEATURED EXPLAINER · METABOLIC ADAPTATION
The energy you already carry—and the protein cost that remains.
A source-linked guide separates fat mobilization from fat oxidation, DXA lean mass from muscle-protein loss, BCAAs from all essential amino acids, and endpoint-specific performance from the vague claim that “performance is preserved.”
The adjoining aerospace scene is a conceptual editorial illustration, not a real participant, approved ration, or operational endorsement.
HISTORICAL COMPARISON · NOT PRECEDENT
The Colorado Experiment rebuilt a detrained former champion. FAST asks nearly the inverse question.
The 1973 case moved a previously elite, detrained bodybuilder toward abundant food and retraining. FAST proposes asking whether a medically governed amino-acid strategy can reduce lean-tissue and performance loss while energy intake is severely restricted. Both stories show why starting condition and muscle memory can dominate interpretation.

FAST QUESTIONS FOR CURIOUS READERS
Open the thought experiment—without mistaking it for an answer.
The proposal becomes more credible when the public can see both the intriguing idea and the reasons it might fail.
If protein becomes amino acids, why not consume only amino acids?
Because digestion is only one part of the problem. Whole foods and intact proteins differ in amino-acid completeness, absorption pattern, satiety, micronutrients, energy, gastrointestinal effects, and how they support the rest of the body. An amino-acid mixture might solve one bottleneck while creating or ignoring others.
What would count as “preserving performance”?
Not merely looking lean. A defensible study would prespecify repeatable measures of strength, movement, endurance, cognition, decision-making, symptoms, adherence, body composition, clinical safety, and recovery. The final primary outcome must be chosen before results are known.
Why not simply start and collect the data?
Severe energy restriction can affect electrolytes, cardiovascular function, endocrine function, kidneys, cognition, mood, lean tissue, and refeeding. Measurements also become meaningless when methods drift. Independent design and medical stopping authority are central to the experiment—not bureaucratic decorations.
What can one participant actually teach us?
A carefully governed feasibility study can expose operational failures, characterize one person's response, test the measurement system, and refine a hypothesis. It cannot establish population-wide effectiveness, prove safety for others, or validate a commercial product.
Is this really a zero-calorie fast?
No. Amino acids provide metabolizable energy and can alter insulin, glucagon, oxidation, and protein turnover. Any defensible protocol must disclose the exact formulation, dose, timing, and total intake rather than use “zero calorie” or “water-only” loosely.
Is FAST a rapid-fat-loss program?
No. Body-fat change would be an observed outcome, not a consumer promise. The proposed research concerns fuel use, endogenous protein loss, lean tissue, function, physiology, safety, and the limits of preservation under extreme constraint.
MARTIAL ARTS PROFICIENCY EXPERIMENT
Fifty bout types test how usable skill changes as pressure increases.
The complete experiment progresses through individual and multiple-opponent bouts, starting disadvantages, training weapons, confined environments, sensory conflict, fatigue, protection of others, advanced Vale Tudo target-zone work, verbal pressure, and civilian high-threat decision circuits.
Individual baselineMultiple opponentsPosition and confined spaceTraining-weapon cuesEnvironment and teamworkFatigue and learningRecovery over timeAdvanced target-zone proficiency
Can reaction, learning, footwork, precision, and judgment remain accurate as nutritional conditions change?
The proposed core battery separates twenty candidate tests across attention, motor learning, martial movement, survival problem-solving, useful work, repeatability, and recovery. A connected Martial Performance Lab now organizes fifty martial-arts proficiency bout types for longitudinal review, including opponent progressions, position changes, inert-prop judgment, teamwork, exertion, learning, civilian high-threat decisions, and recovery.
Both pages record errors as well as speed. Neither is an active protocol. The extreme-exposure concepts are separately identified as theoretical research questions that would require independent institutional governance.
Conceptual editorial illustration; not an active protocol or participant.
MEASUREMENT BOUNDARY
A drill can generate data without becoming a scientific conclusion.
Training content can generate useful measurement ideas. It cannot determine the protocol, override medical stopping rules, or transform a founder demonstration into scientific evidence.
CURRENT STATUS · UPDATED AUGUST 4, 2026
Still a founder-developed proposal—not an active experiment.
Sonny Desposito is the concept proposer. No principal investigator, institutional sponsor, independent scientific reviewer, or medical monitor has accepted responsibility for the project. The concept has not been submitted to or approved by an IRB or ethics committee.
A defensible protocol, endpoints, duration, safety plan, analysis, refeeding plan, intervention composition, and regulatory classification must be established by qualified scientific, medical, and institutional owners. Founder preference does not substitute for independent review.
What should this study be called?
It may ultimately be classified as a single-participant prospective feasibility study rather than a classical N-of-1 trial. The investigator and biostatistician will decide after reviewing the design.
COMMERCIAL-CONFLICT DISCLOSURE
Support can fund the question. It cannot purchase the answer.
Art of Survival operates a separate commercial lane that may sell supplements, apparel, and merchandise. No store product has been selected as the study intervention, scientifically validated by FAST, or endorsed by an investigator or institution.
Cash, products, laboratory credit, equipment, travel, production, or data-platform support would be documented and disclosed. If a qualified institution adopts any version of the research, it must independently review the formulation and manufacturer documentation, disclose relevant financial interests, and determine whether commercial separation is adequate.
Concept and evidence audit State the hypothesis, map the evidence and uncertainty, expose assumptions, and invite independent criticism.
Feasibility disposition Obtain advance, redesign, referral, hold, or decline from qualified scientific and clinical reviewers.
Investigator and institutional ownership Assign principal-investigator, medical, statistical, regulatory, privacy, and operational responsibility.
Design and independent review Freeze the intervention, comparator, endpoints, safety and refeeding plans, analysis, budget, conflicts, and required ethics or regulatory submissions.
Formal activation Begin only if the institution activates the work after approvals, contracts, facilities, systems, and accountable owners are ready.
Transparent reporting Analyze to the prespecified plan and report limitations, deviations, null results, and harms.
There is no promised activation date. Any gate may require material redesign or end the project.
CRITIQUE IS A CONTRIBUTION
Challenge the assumptions, propose a safer design, or point us to the right expert.
Qualified perspectives in metabolism, clinical nutrition, sports medicine, exercise physiology, biostatistics, bioethics, regulatory science, clinical research operations, and laboratory measurement are welcome. A first conversation should answer three questions: Is the evidence gap worth pursuing? What is the lowest-risk informative precursor? Which investigator and institution could legitimately own it?
Choose a technical brief or a plain-language reading path.
The public investigator brief consolidates the proposed question, present status, scientific uncertainties, requested expertise, governance boundaries, and open decisions. The Field Notes translate related nutrition, performance, logistics, and measurement ideas for general readers without presenting the hypothesis as a result.
