All Episodes: The GLP-1 Podcast

Consultant dermatologist Dr Aamna Adel explains why hair sheds after rapid weight loss on GLP-1 medication, what the latest 548,000-pair study tells us about the cause, and how long regrowth really takes. She also covers which treatments have evidence behind them and which are a waste of money.

Journalist and cosmetic concierge founder Olivia Falcon joins Marc to talk about what genuinely helps a face that has changed after major weight loss, and what is being oversold. She covers which treatments are worth paying for, how to check a practitioner's credentials, and the red flags that should make you walk away.

Couples therapist Jonathan Van Viegen explains what walks into his therapy room when one partner changes fast on a GLP-1, and why the partner who stayed the same is the person nobody asks about. He and Marc cover the conversations couples are not having, the questions to ask instead, and what being chosen looks like day to day.

Anthropologist Dr Treena Orchard explores why identity lags so far behind a body that changes fast, and what people fear losing when they admit they're on a GLP-1. She and Marc discuss why these drugs get moralised, what the advertising is really selling, and what happens in a long relationship when one partner changes.

GP and exercise scientist Dr Ash Bowden explains what happens to muscle and bone during rapid weight loss on GLP-1s, and what protecting your muscle actually looks like on an ordinary tired evening. He and Marc cover where to begin with resistance training, whether walking is enough, and how to move with a bad back or sore knees.

Plastic surgeon Dr Frank Agullo explains why skin doesn't bounce back after rapid weight loss, what is really happening behind "Ozempic face", and how the face, breasts and midsection each behave differently. He and Marc also cover what skincare can genuinely do, when surgery makes sense, and what before-and-after photos online hide.

Dr Komal Patil-Sisodia explains what really changes in a woman's metabolism through menopause, why heart disease is so badly under-appreciated in midlife, and where GLP-1 medications and HRT each fit. She and Marc also cover the tests women should be asking for and what to do when you've been told it's just your age.

Clinical pharmacist Nyrah Saleem explains why hair sheds a few months into rapid weight loss, how long it takes to grow back, and what genuinely speeds recovery up. She and Marc also go through the nutrient deficiencies worth testing for, how to read a supplement label, and which products are just expensive gimmicks.

Harvard Medical School obesity specialist Dr Fatima Cody Stanford explains what obesity actually is, why set point theory defeats dieting, and what the triple agonist retatrutide could mean. Marc and Dr Stanford also cover weight stigma in the clinic, who will and won't get access to these drugs, and the body dysmorphia that remains after the weight has gone.

NHS surgeon Dr Karan Rajan explains what GLP-1 medications are really doing inside the gut, why the side effects vary so much, and which ones you can actually do something about. Marc and Karan also cover why fibre matters more than anyone told you, the biggest GLP-1 myth circulating online, and the idea that these drugs are somehow cheating.

Anna Cadman talks about losing eight stone on Mounjaro and the serious complications that followed, including gallstones, pancreatitis and a hospital stay. She and Marc also cover food addiction, the danger of daily weigh-ins and her plan for maintenance.

Marc sits down with his friends Emma Cottey and Rue Ndabalime to talk about what support really looks like on a weight loss journey, and how friendships and family relationships shift as you change. They share their lowest points before starting, the stigma they kept to themselves, and what still feels unfinished.

Plastic surgeon Dr Gediminas Samulenas explains why loose skin happens after major weight loss, when surgery is and isn't appropriate, and how long to hold a stable weight first. He and Marc also cover nutrition and mental readiness before an operation, and how to vet a surgeon or clinic.

In this solo episode Marc talks through how his skin changed after losing 126lbs on Mounjaro, especially his face and neck, and everything he tried along the way. He explains what genuinely helped, where skincare reaches its limits, and the thinking that led to ElastiK Skin.

James Taylor explains how he went from dismissing GLP-1s as the easy way out to losing eight stone, reversing his pre-diabetes and lowering his blood pressure. He and Marc talk about breaking the "I'll start on Monday" cycle, shame around weight, and finding the confidence to run and join a gym.

Dr Sachin Khunti brings both a clinician's and a patient's view to obesity, explaining why the body biologically defends its weight and why regain is physiology rather than failure. He also talks about his own GLP-1 experience, stopping and restarting treatment, and the stigma that stops people seeking help.

Dr Mike Herring, a double board certified doctor and personal trainer who lost over 100 pounds himself, explains why so many people struggle on GLP-1 medications. The conversation covers minimum effective dosing, cravings and food noise, protein and muscle retention, realistic movement, sleep, and why habits rather than the medication alone decide long term results.

Hira Malik, Chief Pharmacist and Co-Founder of Oushk Pharmacy, sets out what safe GLP-1 prescribing actually looks like and the red flags that signal an unregulated seller. The conversation covers common myths about regain and side effects, the three maintenance routes her pharmacy offers, and the real dangers of counterfeit and black market injections.

Aja Beckett, founder of the Shotsy app, talks about the support gap that opens once a GLP-1 prescription is filled. The conversation covers the emotional and identity shifts that come with weight loss, stigma around obesity treatment, why tracking doses and side effects leads to better conversations with prescribers, and what she has learned from building a tool used by hundreds of thousands of patients.

Dr Adam Jameson, a pharmacist and PhD in pharmacogenomics at REVIV, explains why fatigue, hair thinning and low mood can appear on GLP-1 medications and what is usually behind them. The conversation covers the most common nutrient deficiencies, protein and muscle mass, when blood testing and IV therapy make sense, and how genetic testing can personalise supplementation.

Amie Moore, who has lost nearly seven stone on a GLP-1, shares what happened when severe pain under her ribs turned out to be gallbladder disease requiring emergency surgery. The conversation covers why rapid weight loss of any kind raises gallstone risk rather than the medication itself, the symptoms she wishes she had recognised sooner, online trolling, and how she is restarting her journey.

Nathan Hindle, founder of Manchester wellness studio Brysk, explains how recovery treatments can support people on a GLP-1 journey. The conversation covers what whole body cryotherapy does to the body, red light and hyperbaric oxygen for energy and muscle, compression boots and lymphatic drainage for easing back into movement, and why sleep and mental resilience matter as much as the physical side.

Marc turns the microphone around and answers questions from his friends Rue Ndabalime and Emma Cottey about his own GLP-1 journey, from the doctor's warning that started it to losing 126lbs. The conversation covers the first four weeks, the non-scale moments that proved it was working, the mental struggle of recognising a changed body, and what maintenance actually looks like day to day.

Brandon Gee, who has lost over 50 kilograms on a GLP-1, talks about the part of transformation that rarely gets discussed: what comes after the weight loss. The conversation covers the fear of regain and what he learned when switching medication put weight back on, loose skin and body image, why slower loss can build better habits, and finding movement you actually enjoy.

Personal trainer and GLP-1 coach Mitch O'Callaghan joins Marc to explain why movement matters on a GLP-1 journey, how muscle and bone density are really lost, and where to start if you have no energy or feel too intimidated for the gym. They also cover the most common training mistakes, adapting around injury or disability, and how men and women should approach training differently.

Emma Cottey, a full-time working mum of two, joins Marc to talk about losing over eight stone on Mounjaro while raising a family. She shares the Peppa Pig World moment that started it all, how she plans meals and gym sessions around her children, and how she handles the guilt of taking time for herself.

Functional medicine doctor Dr Dean Jones joins Marc to compare how GLP-1 medication is accessed in the UK versus the US, from NHS red tape and BMI thresholds to American out-of-pocket costs and compounded supply. They also dig into the under-eating problem, medication resets, protecting muscle mass, and why the medication only works alongside real lifestyle change.

Kirsty Ginger joins Marc to talk about going through NHS tier three and four weight management, bariatric surgery, and then adding Mounjaro two years post-op to lose over 13 stone in total. She is candid about grieving food, foamies and dumping, finding a pharmacy willing to support a complex patient, and the identity shift that came with the loss.

Clinical psychologist Dr Lucy Harvey joins Marc to talk about the mental side of a GLP-1 journey: why identity shifts hit so hard when the body changes faster than the mind, where guilt and shame come from, and how to plan for the questions other people will ask. She also shares practical ways to move from being your own biggest critic to your own cheerleader.

Rue Ndabalime joins Marc to talk about the cultural side of a GLP-1 journey, from keeping her Zimbabwean traditional foods on the table to the stigma around injecting medication in her community. She shares the health scare that started it all, the friendships she lost along the way, and how she learned to love herself again.

Hira Malik, Superintendent Pharmacist and Lead Prescriber at Oushk Pharmacy, joins Marc to explain what safe pharmacy support looks like when starting a GLP-1. They cover the red flags of black market and fake medication, the new GPhC BMI verification rules, the most common patient worries about side effects and cost, and why education and maintenance matter as much as the prescription.

Marc shares the wake-up call that started everything: being told he might not live to 40, and what the UK obesity figures really look like behind the headlines.
