The Dr. Jules Plant-Based Podcast

Collagen promises smoother skin, happier joints, and faster recovery, but what holds up when we strip away the hype and read the best studies? 
We unpack the newest research since 2023 and draw a clear line between modest, measurable effects and results that melt under tighter controls. If you’ve wondered whether those powders and gummies are worth the price, this conversation gives you honest context without shaming your choices.

We start by laying out how to read supplement science: funding bias, placebo controls, sample size, and why meta-analyses can mislead when they pool weak trials with a few strong ones. 
For joint pain, we highlight small to moderate improvements in osteoarthritis outcomes seen in several meta-analyses, balanced by a rigorous trial that found no advantage over placebo. The takeaway is measured: collagen is not a cure, but some people feel a little better, especially alongside strength training, movement, and weight management.

Skin health is a different story. 
We dig into a 2025 meta-analysis showing that benefits largely appear in industry-funded studies, while high-quality independent trials see no meaningful changes in wrinkles, hydration, or elasticity. We explain the biology, collagen is digested into amino acids, and why sunscreen, sleep, protein-rich whole foods, vitamin C, zinc, copper, and smart skincare move the needle more. 
On muscle and recovery, we clarify that collagen is an incomplete protein and poor at stimulating muscle protein synthesis, yet may support connective tissues when paired with resistance training, offering small improvements in recovery or fat-free mass for some.

You’ll walk away with practical priorities: train progressively, eat enough complete protein, protect your skin from the sun, sleep deeply, and manage stress. If you choose to test collagen, define your goal, set realistic expectations, track changes, and reassess your budget. 
If this helped you think clearer about supplements and what actually works, follow the show, share it with a friend who’s collagen-curious, and leave a quick review to help others find us.

La phrase la plus dangereuse en santé pourrait bien être « Je me sens bien ». 
Nous expliquons comment un déclin silencieux, dans la MPOC comme dans la perte musculaire liée à l’âge, peut gruger la fonction bien avant que les symptômes ne deviennent alarmants, et pourquoi la prévention demeure la meilleure stratégie pour préserver l’autonomie. 
À partir d’un cas réel de patient, nous décortiquons ce que signifie réellement un VEMS à 44 %, comment chaque infection respiratoire laisse une atteinte permanente à la capacité pulmonaire, et pourquoi les vaccins et les inhalateurs peuvent faire la différence entre bien vivre et enchaîner les hospitalisations.
Nous passons ensuite aux muscles : à quoi ressemble la sarcopénie dans la vie de tous les jours, pourquoi se lever d’une chaise constitue un test fonctionnel révélateur, et comment l’apport en protéines et l’entraînement en résistance progressive permettent de reconstruire la force. Vous repartirez avec des cibles pratiques appuyées par les données probantes, soit 1,2 à 1,6 g/kg de protéines, un entraînement en force pour maintenir la masse musculaire et la densité osseuse, ainsi que du travail aérobie et d’équilibre pour préserver la fonction cardiopulmonaire, sans oublier les habitudes simples qui rendent ces changements durables. Nous abordons aussi le sommeil, la connexion sociale, la régulation du stress et l’activation du nerf vague comme des piliers essentiels d’un système résilient.
Ce message n’est ni centré d’abord sur les pilules ni opposé aux médicaments. Il s’agit plutôt d’un plaidoyer pour des choix éclairés : comprendre les risques de l’action et de l’inaction, remettre en question la désinformation, et aligner les outils, habitudes de vie, médicaments et vaccins, avec vos objectifs. 
Si vous souhaitez éviter l’oxygène, rester hors de l’hôpital et conserver la force nécessaire pour marcher un 5 km à 70 ans, le travail commence maintenant. Écoutez, réfléchissez, puis choisissez le changement que vous mettrez en place cette semaine. Si cet épisode vous a aidé à voir la prévention et la longévité autrement, abonnez-vous, partagez-le avec une personne qui a besoin d’un petit coup de pouce et laissez un court avis pour aider d’autres à le découvrir.

Your body doesn’t treat breakfast and dinner the same way, and once you understand why, meal timing becomes a powerful lever for better health. We dig into chrononutrition, the science of how circadian rhythms shape appetite, insulin sensitivity, and energy metabolism, and we translate it into simple steps that fit real life.

We start by mapping the daily hormone dance: morning light sparks a cortisol rise that mobilizes energy, adenosine builds sleep pressure through the day, and melatonin ushers in nighttime repair. 
Those rhythms change how your body handles the same plate of food across the clock. Insulin sensitivity is highest earlier, glucose tolerance declines later, and fat oxidation slows in the evening. That shift helps explain why late-night eating links to insulin resistance, prediabetes, type 2 diabetes, and cardiovascular risk, even when total calories don’t change.

From there, we reframe fasting. Skipping breakfast often reduces calories but can backfire metabolically, with worse insulin sensitivity and blood pressure. Early time-restricted eating tells a different story: front-load calories, move dinner earlier, and minimize late-night intake. Studies show improved insulin sensitivity, blood pressure, and cardiometabolic markers when the eating window aligns with the body clock. A calorie at 8 a.m. meets a system primed to use energy; the same calorie at 10 p.m. meets a system preparing for sleep.

You’ll leave with clear, practical tools: anchor breakfast and lunch, keep dinner earlier and lighter, aim for consistent meal timing, get bright light soon after waking, dim light at night, and treat late snacking as a stressor. Whether your goal is better glucose control, sustainable weight management, or heart health, aligning meals with your circadian rhythm can amplify results without adding restriction.

If this helped reframe how you think about food timing, follow the show, share it with a friend who loves nutrition science, and leave a review with your biggest takeaway.

Une mémoire n’est jamais qu’un simple fichier dans le cerveau, c’est un fil qui nous relie à ce que nous sommes. 
Nous ouvrons l’épisode avec des récits sincères tirés de l’expérience de notre propre famille avec la maladie d’Alzheimer, ainsi que du poids silencieux porté par les proches aidants, puis nous passons à ce que la science nous dit aujourd’hui pour protéger l’esprit de demain. L’objectif n’est ni la perfection ni la peur, mais une prévention pratique, ancrée dans la vraie vie.
Nous expliquons la différence entre la maladie d’Alzheimer et les autres formes de démence, pourquoi l’espérance de vie moyenne après le diagnostic se situe souvent entre 7 et 10 ans, et comment les habitudes adoptées tôt peuvent bâtir une réserve cognitive. 
L’activité physique occupe une place centrale : l’exercice régulier augmente le BDNF, renforce les connexions neuronales et soutient la santé vasculaire dont le cerveau dépend. Les entraînements mentaux comptent aussi. La lecture, les mathématiques, l’apprentissage des langues et les jeux de mémoire contribuent tous à garder les circuits cérébraux souples et résistants.
Les choix alimentaires complètent l’approche. Nous décortiquons le régime MIND et ses racines dans les modèles méditerranéen et DASH, en mettant l’accent sur les légumes verts feuillus, les petits fruits, les légumineuses, les grains entiers, les noix, les graines, l’huile d’olive et les oméga-3 provenant du poisson ou des algues. 
Plutôt que de débattre des étiquettes, nous nous concentrons sur les résultats : une alimentation riche en fibres, un apport protéique adéquat, moins de gras saturés et une grande variété d’aliments végétaux riches en antioxydants et en composés phytochimiques comme les anthocyanines et le sulforaphane. 
Nous apportons aussi de la nuance à la notion d’aliments « transformés », en expliquant comment l’enrichissement peut être utile, pourquoi toute transformation n’est pas néfaste, et à quel moment les produits ultra-transformés commencent à remplacer une nutrition de qualité.
Si vous cherchez un point de départ simple, essayez ceci : comptez les couleurs plutôt que les calories et visez trois à quatre couleurs dans chaque assiette. 
Construisez de petits rituels, une portion supplémentaire de légumes verts, une marche de 20 minutes, un casse-tête hebdomadaire, qui s’additionnent au fil des mois. Votre cerveau, votre cœur et votre futur vous en remercieront.

What if the grind that built your career is quietly breaking your health? 
We share a candid story of chasing productivity through 70–80 hour weeks, new fatherhood, on-call nights, and late teaching prep that spiraled into stress, palpitations, and creeping burnout, then the pivot that turned sleep into a non-negotiable performance tool.

Together we unpack why sleep is an active biological process, not downtime. You’ll hear how deep sleep drives tissue repair and metabolic recovery, how REM consolidates memory and stabilizes mood, and why the brain’s glymphatic system clears waste most effectively at night. 
We connect the dots between short or fragmented sleep and higher risks of hypertension, insulin resistance, cardiovascular disease, cancer, and all-cause mortality, and we talk frankly about circadian rhythm disruption and why shift work raises disease risk across populations.

We also get practical. Learn how consistent bed and wake times strengthen your internal clock, how dimming lights and reducing blue light support melatonin, and how to build a wind-down routine that conditions your brain to switch states on cue. 
We share simple cues, light stretching, a brief breath practice, a sleep mask, less evening caffeine and alcohol, that protect sleep architecture and translate into clearer focus, steadier mood, and better choices the next day. The takeaway is simple and powerful: productivity without recovery is a dead end; prioritize sleep and the other lifestyle pillars naturally align.

If this resonates, follow the show, share it with a friend who’s burning the candle at both ends, and leave a quick review to help others find these tools. Your eight hours might be the most effective upgrade you make this year.
