N-acetylcarnosine eye drops penetrate the eye and act as a decoy to prevent lens glycation in cataracts.

"You need the N-acetyl to drive it as a as a Trojan horse. It goes it pushes it through the eye in these drops. You can get them. You'll see them probably for dogs, but they have them for humans as well. So you put it on your eye, it goes into the eye, and it helps to, um, act as a decoy to to prevent this—it's called glycation—on the, uh, the lens." (said at 0:36:14)

The speaker accurately describes the biochemical rationale and prodrug design of N-acetylcarnosine (NAC): unmodified L-carnosine cannot effectively cross the cornea, so N-acetylation enables corneal penetration into the anterior chamber, where it is deacetylated to carnosine and can act as a sacrificial scavenger (decoy) against protein glycation and oxidative cross-linking in the lens. However, important context is required regarding clinical efficacy: a Cochrane systematic review concluded there is currently no convincing clinical evidence that NAC eye drops prevent the progression of or reverse age-related cataracts in humans.

Dietary protein stimulates the secretion of glucagon, an opposing hormone to insulin that aids in weight loss.

"And you need high quality protein. Keep your protein in there. That's going to be important. It's going to stimulate uh something a hormone called glucagon, which then will help you also lose weight. It's the opposite of insulin." (said at 1:03:20)

The host's statement is fundamentally correct in its physiological direction, but requires qualification. Dietary protein and amino acids stimulate the release of glucagon from pancreatic alpha cells, a hormone that acts as a counter-regulatory opposing hormone to insulin. Glucagon receptor activation promotes energy expenditure and hepatic lipid metabolism, contributing to metabolic weight management. However, attributing protein-induced weight loss solely or primarily to endogenous glucagon secretion oversimplifies the process: postprandial dietary protein also stimulates insulin secretion (to maintain blood glucose homeostasis) along with gut satiety peptides (such as GLP-1 and PYY), and marked weight loss via glucagon receptor activation is primarily established through pharmacological glucagon receptor agonism rather than physiological dietary stimulation alone.
