The 20-Hour One-Meal Protocol is Wesley Hunt’s schedule-matched form of intermittent fasting. He waits 20 hours after his last meal, drinks black coffee and water during the fasting period, and then eats one deliberately substantial meal. The mechanism is simplicity: compressing intake into one planned event reduces the number of restaurant meals and food decisions that can accumulate during travel-heavy days. The meal is not presented as small; Hunt describes large servings of steak or chicken alongside foods such as sweet potato, broccolini, and salad. He arrived at the protocol after trying other meal frequencies and stresses that it works for his body and life rather than for everybody. Adaptation took about a month.
Origin
Hunt says he tried multiple eating patterns, including six small meals a day, before settling on a 20-hour fast because it best matched his travel, workload, and appetite.
Core principles
- 01A routine must fit the life that has to sustain it
- 02A fixed eating window reduces unplanned meal opportunities
- 03Adaptation takes time
- 04Individual response matters more than a universal prescription
How to run it
- 1
Test schedule fit
Assess whether one daily meal can realistically fit your work, travel, and training demands. Treat the protocol as an individual experiment rather than a universal rule.
Pro tip Compare it with meal patterns you have actually tried, not an idealized routine.
Watch out Seek appropriate medical or nutritional guidance before using a prolonged daily fast.
- 2
Start the 20-hour interval
Count 20 hours from the end of the previous meal. Keep the fasting routine simple with water and black coffee, as Hunt describes.
Pro tip Anchor the meal at a repeatable time when possible.
Watch out Do not force the interval through adverse symptoms.
- 3
Plan the substantial meal
Build the one meal around a large protein source and include other foods such as vegetables and a carbohydrate source. Plan enough food for the meal to be genuinely satisfying.
Pro tip Decide the meal before a restaurant or travel day creates extra choices.
Watch out Hunt’s unusually large portions reflect his own appetite and activity, not a serving recommendation.
- 4
Allow an adaptation period
Expect the change to feel difficult initially and observe how the routine settles over several weeks. Hunt reports that his perspective changed after about a month.
Pro tip Track energy, training, concentration, and adherence rather than weight alone.
- 5
Keep or reject by evidence
Judge the protocol by whether it remains workable across busy days and travel. Adjust or abandon it if it does not fit your body, obligations, or health needs.
Pro tip The best routine is the one that remains stable in your real schedule.
In the wild
Hunt describes fasting through a busy day and then eating a large dinner built around steak, a whole sweet potato, broccolini, and a dinner salad. On another day, his main protein was a whole rotisserie chicken.
→ One planned eating event replaces repeated meals during a travel-heavy schedule.
Common mistakes
Copying the portion size
The framework is the timing and planning structure, not Hunt’s exact quantity of food. Portion needs vary by person.
Treating one method as universal
Hunt explicitly says the routine is not for everybody. A protocol that conflicts with health or daily life fails the fit test.
Ignoring the adaptation period
Early difficulty does not reveal whether the routine will become sustainable, but persistent problems are also not a reason to force it.
Is it for you?
Best for
It is best for an experienced adult who prefers one large meal and can safely tolerate a long daily fast.
Not ideal for
It is not ideal for anyone with medical, nutritional, or training needs that require more frequent intake.
