Day 3 is where things shift for most people. Hunger quiets, energy steadies, and the hardest part is already behind them. The 3-Day Kit ends right there, at the turn.
The 5-Day Kit uses that same turn as a starting point rather than a finish line. Two more days, once the body has adjusted, give the later, steadier part of the reset more room to run. One kit gets you to the turn. The other is what happens after it.
Suits a travel week, a demanding stretch, or a monthly reset.
Suits the full arc, once every two months.
Every meal in the kit is portioned to land inside a specific window, verified in an NABL-accredited lab. Go much lower and the days get harder without much to show for it. Go much higher and the reset stops being much of a reset at all. Around 950 kcal a day is the range where the five days actually do something, without asking more of the body than it can spare.
Not enough to draw on for the day ahead.
Around 950 kcal a day. Where the reset lives.
The everyday range most people already eat in.
