103: Does the HCG Diet Actually Work? What the Studies Really Say with Dr. Ben Bikman
📢 Ask Dr. Bikman’s Digital Mind: https://benbikman.com/ben-bikmans-dig... 📢 Dr. Bikman’s Coaching Site, Insulin IQ: https://insuliniq.com 📢 Become an Insider on Ben’s website: https://www.benbikman.com During this Metabolic Classroom lecture, Dr. Bikman unpacks the history, claims, and science behind the controversial HCG diet. Originally popularized in the 1950s by Dr. Albert Simeons, the diet pairs daily HCG hormone injections with an extremely low-calorie diet (around 500 calories/day). Simeons claimed that HCG helps target problem fat areas, preserve muscle, and suppress hunger. Ben explains HCG’s legitimate role in pregnancy and medical uses (e.g., infertility and hypogonadism), but emphasizes that its weight loss effects are unproven in non-pregnant individuals. Ben reviews numerous randomized controlled trials and meta-analyses, all of which consistently show that HCG provides no measurable benefit over placebo for weight loss, hunger suppression, or muscle preservation. Anecdotal success stories may stem from the extreme calorie restriction or a placebo effect, rather than any metabolic impact of HCG. He explains that even pregnancy-level HCG doses only mildly affect thyroid hormones and that therapeutic doses used in the diet are far too low to significantly alter metabolism or fat-burning. Biochemical and in vitro studies show that HCG may stimulate fat cell growth, particularly in newborns and under high concentrations, but it does not increase lipolysis in adult fat tissue. This contradicts the idea that HCG helps “melt” fat from stubborn areas. Furthermore, its role in reducing hunger is more likely due to nausea or psychological commitment rather than true satiety signaling. In conclusion, Dr. Bikman cautions against using HCG as a shortcut for weight loss. The extreme calorie restriction is effective but unsustainable and potentially harmful. He recommends lowering insulin by controlling carbohydrates as a healthier first step, emphasizing a protein-focused, low-carb approach over starvation and hormone injections. He encourages individuals to base their choices on rigorous science, not fad claims. Show Notes/References: For complete show notes and references, we invite you to become an Insider subscriber.
