90: Peptides & Metabolism - Fat Loss, Muscle Growth, and Hormones Explained with Dr. Bikman

📢 Ask Dr. Bikman’s Digital Mind: https://benbikman.com/ben-bikmans-dig...

Dr. Bikman’s Metabolic Classroom lecture this week explores peptides and their effects on metabolism, fat loss, muscle growth, and overall health.

Ben begins by defining peptides as short chains of amino acids that act as signaling molecules in the body. While some peptides occur naturally, others are synthetically developed for therapeutic purposes. He explains that peptides are gaining popularity in fitness, anti-aging, and metabolic health, influencing fat loss, muscle repair, insulin sensitivity, and even skin regeneration. He also introduces collagen peptides, highlighting their unexpected metabolic benefits, including their influence on GLP-1 and gut microbiome health.

Ben then categorizes peptides based on their primary functions. For fat loss, peptides like CJC-1295 and Tesamorelin work by stimulating growth hormone and IGF-1, promoting fat breakdown while preserving muscle mass. Another peptide, Melanotan-2, originally known for increasing melanin, has been found to suppress appetite by affecting the melanocortin system. He also discusses peptides like Ipamorelin, which help enhance muscle recovery and growth by selectively increasing growth hormone secretion without affecting other pituitary hormones.

In the anti-aging and skin health category, Thymosin Beta-4 stands out for its ability to enhance wound healing and tissue repair. Dr. Bikman also highlights the unexpected metabolic role of collagen peptides, explaining how they can increase GLP-1 levels, improve insulin sensitivity, and even activate AMPK, a crucial metabolic regulator involved in fat breakdown and cellular repair.

Finally, he touches on how peptides are administered—most commonly via subcutaneous injections, though some peptides can be absorbed sublingually or applied topically.

He cautions that not all peptides are created equal, warning against low-quality or counterfeit products. Ben emphasizes the need for high-quality sourcing and careful monitoring, as some peptides affect hormone levels and require medical supervision.

Dr. Bikman concludes that peptides hold immense potential for metabolic health, fitness, and longevity, but should be used wisely and responsibly.
