WHAT YOU GET

A real reset. Sustainably.

One day of nourishing, clinically-studied food. Designed to get you into ketosis — quickly.

Clarity
A noticeable shift in how clearly you think and feel — most pronounced the morning after.
Lightness
A literal, physical sense of ease — the kind your body asks for after a heavy stretch of eating.
Reset
Reset can help reduce cravings. Many customers report making different choices for days afterward — naturally.
Ease

CHOOSE THIS, NOT THAT

A real reset, not a workaround.

There are a lot of ways to try to feel better in a day. Most of them are some version of "less" — less food, less sugar, less you. The Reset is "more, intentionally."

Instead ofA juice cleanse with more sugar than dessert
Try thisA nourished day of real, plant-based food. No sugar crash, no false promises.
Instead ofThe latest fad diet with no science behind it
Try thisA protocol built on the same nutrition science behind Prolon's Fasting Mimicking Diet.
Instead ofA multi-week cleanse program you'll quit by day three
Try thisA single day. Start in the morning, finish before bed. Done.
Instead of"I'll just skip a meal" or white-knuckling through it
Try thisThree real meals, calibrated by science. A day designed to support the way you want to feel.
WHY IT WORKS

Real fasting science, in 24 hours.

1

Real food. Real fasting biology. Real difference.

Three meals of real, plant-based food — calibrated ingredient by ratio to stay below your body's nutrient-sensing thresholds. That's the patented Fasting Mimicking Technology® developed by L-Nutra over 25+ years of research. You eat. Your body experiences a fasting state. The science of a fasting day, in a format you can actually do.

Three meals. Real food. The whole day, taken care of.

A plant-based bar in the morning. A nourishing soup, premium olives, and almond and kale crackers at midday. A second soup and bar in the evening. Every ingredient is chosen and calibrated to give your body what it needs while letting it rest. You don't have to plan, prep, calculate, or guess.

Real food, all day

WHAT'S HAPPENING INSIDE

24 hours. Four phases.
A real reset.

Not theoretical, not marketing. The actual biology of what your body does over 24 hours of fasting-mimicking nutrition.

HR0–6
Glucose stores begin depleting
Morning meal: a plant-based bar and herbal tea. Your body uses up its readily-available glucose first. You feel mostly normal — just lighter than a typical breakfast. The fast has started, even though you've eaten.
HR6–12
Fuel switching begins
Midday meal: soup, olives, crackers. Glucose is running low, and your body starts shifting toward fat as its fuel source. The sharp "fasting hunger" some people fear softens here, because you're nourished — not starving.
HR12–18
Ketosis activates
Your body is now producing ketones — using fat for fuel. The 1-Day Reset is calibrated to get you here in a single day. Many customers report a noticeable shift in mental clarity in this window.
HR18–24
A nourished close to the day
Evening meal closes the day. Your body has spent hours in a fasting state — and the morning after, many customers report a noticeable shift in how they feel.
