Snacking frequently does keep insulin elevated more often than a more spaced-out eating rhythm, but the idea that the human body "wasn't designed to graze" and that intermittent fasting delivers a benefit beyond simply eating less isn't what trials comparing the two approaches at matched calorie intake show.

Stripped of the personal story ("it changed my life"), the mechanistic claim, eating more often keeps insulin elevated longer, is correct basic physiology: each intake triggers insulin secretion, so more intakes mean more time spent in a postprandial state. The weak point is the evolutionary argument ("we weren't designed to graze") used to justify a superior benefit of intermittent fasting: trials comparing intermittent fasting to matched continuous calorie restriction (the HELENA trial, Templeman et al. 2021) find no consistent fasting advantage on metabolic markers or body composition. Intermittent fasting may well have helped this person lose weight and feel better, often because it simplifies eating less overall, but that isn't proof that meal frequency has its own effect independent of total calories eaten. The rest of the video mixes well-established points (magnesium helps with sleep and cramps) with shakier shortcuts (colon cleanses, shoulder pain always being liver-referred), which is a reason to judge each claim separately rather than as a package.
