what it claims

For younger-looking skin, consume more protein (0.75-1g/lb of body weight), incorporate fermented foods for the microbiome, reduce sugary drinks (sodas/sweetened coffees) to avoid glycation, and prioritize dark chocolate (>70% cocoa) for its antioxidants.

The advice on protein is consistent with its structural role in collagen synthesis, although the recommended intake is a general estimate for overall health rather than a precise dermatological target (observational studies). The skin-microbiome axis (fermented foods) is an active and promising area of research, showing connections via the gut-skin axis, although direct clinical evidence on skin rejuvenation remains limited (observational studies/small trials). The warning against sugar is scientifically sound: glycation (formation of advanced glycation end-products or AGEs) is a recognized mechanism that weakens collagen fibers (mechanistic studies). Dark chocolate rich in cocoa is supported by clinical studies showing that its flavanols can improve skin hydration and microcirculation (randomized controlled trials). The overall advice is aligned with a holistic preventive approach, although the term 'rejuvenate' is a marketing simplification of mechanisms protecting against premature aging.

What the graded evidence says

Evidence: B+

Effect: fat-free mass gain (resistance training) and appetite/satiety — +0.30 kg fat-free mass with protein supplementation (95% CI 0.09-0.52), plateau at ~1.62 g/kg/day; higher protein meals reliably increase satiety vs equal-calorie lower-protein meals
Measured on: healthy training adults; weight-loss and weight-maintenance adults

More protein past roughly 1.6 g/kg/day doesn't add much for muscle or fullness. The satiety edge is real but modest, not a magic appetite switch.
