In this solo segment, Ben Greenfield explains why many people using GLP‑1 weight‑loss drugs experience loose or hanging skin. He notes that the rapid fat loss induced by GLP drugs outpaces the skin’s ability to remodel its collagen and elastin fibers, leading to stretched and fragmented connective tissue and an average loss of about 7% facial volume for every 10 kg of weight lost. Greenfield then offers three practical strategies to mitigate this effect. First, he recommends consuming adequate protein and staying well‑hydrated to rebuild muscle volume beneath the skin, which can fill space and reduce a draped appearance. Second, he cites a meta‑analysis of 26 randomized controlled trials involving over 1,700 participants that showed collagen peptide supplementation significantly improves skin elasticity. Third, he suggests red and near‑infrared light therapy performed 3–5 times per week for 6–12 weeks (10–20 minutes per session) to support collagen and elastin health. The segment blends physiological explanation with evidence‑backed lifestyle interventions aimed at preserving skin integrity during rapid weight loss.

A lot of people are losing a lot of weight with GLP drugs, but they're then complaining about loose skin and hanging skin. So, your skin doesn't snap back right after you've gone through a series of GLP drug use, and that's for 3 reasons. Fat loss when you're on a GLP outpaces the rate that collagen and elastin in your skin can remodel. Your existing collagen and elastin fibers get stretched and they get fragmented, and people lose about 7% of facial volume for every 10 kilograms of weight that they lose. What you could do even if you weren't on GLP drugs for loose skin issues, number one thing is eat adequate protein and stay hydrated because that will help to rebuild muscle volume under the skin. It will fill space. It will reduce that draping look. The next thing is collagen peptides. So, a meta-analysis of 26 different randomized controlled trials with Over 1,700 people found a significant improvement in skin elasticity with supplementation of collagen peptides. Red and near-infrared light are out 3 to 5 times per week over 6 to 12 weeks at 10 to 20 minutes per day to be something that contributes to collagen and elastin health.
