DietDoctor podcast
High Intensity Health with Mike Mutzel (both podcast and YouTube)
Found My Fitness with Rhonda Patrick (both also, with some topics those slides do help!)
Human Performance Outliers (carnivore diet and ultra-fitness)
New: LowCarbMD Podcast (in conjunction with Dr. Fung) Only 11 episodes to catch up 
Paleo Solution Podcast with Robb Wolf (he is an excellent interviewer, has great guests, even if he personally not “keto”) Years of smart interviews in the Archive.
Stem-Talk (the podcast from TheIHMC) Their years of YouTube talks have so much on LC Health, (also space and robots) Pick health topics of interest, consider the YouTube channel if ever have the time to watch a lecture. Dr. Colin Champ’s talks about Cancer and Diet are so popular, think 2018 was his third or fourth invite. https://www.youtube.com/user/TheIHMC
As others have mentioned, you can also download the podcast archives from The Low Carb Cardiologist and The Obesity Code. There is a really old limited series (2012) by Jimmy Moore “Ask the Low Carb Experts” where each episode covered only one topic with one expert. Can’t stand his regular podcasts, particulary in the past five years, but I remember this series as very helpful.
Enough to get you started. How I found some of these is going to Podcast Store, and filtering by top ranked podcasts in the Health, Dieting and Fitness category. That is always an option…I do that on occasion to find popular new ones.
