Dr Alan Desmond: A WFPB gastroenterologist from UK. Low FODMAPs are covered at offset 30:17 in this video (watch till 34:02). He also mentions the The Happy Gut Course which explains Low FODMAP.

Dr Will Bulsiewicz is a WFPB gastroenterologist; author of Fiber Fueled (400 pages, 2020). He explains Low FODMAP in this video: Dealing With Food Sensitivity (5 mins, 2018). Two main ideas caught my attention: (a) Work with a nutritionist or doctor to follow Low FODMAP Diet, and (b) Moderate, don't eliminate.

Dr Michael Greger: In Fiber vs Low FODMAP for SIBO Symptoms (5 mins, 2021), Dr Greger says:

To grasp the significance of fiber, gut bacteria and prevotella vs bacteroides mentioned in Dr Greger's video, it would help to browse through articles in Gut Microbiome and Fiber.

Dr Angie Sadeghi: How to Eat to Relieve IBS and Heal Your Gut (67 mins, 2020) is a fantastic exposition of IBS (which often gets confused with SIBO), hosted by ForksOverKnives. Low FODMAP is covered at offset 37:59 of her presentation.

Dr Sadeghi explains why she is not a fan of Low FODMAP. Basically, in Low FODMAP, we remove 5 broad classes of foods ("excess fructose", "lactose", "fructans", "galactans" and "polyols"). Four of these classes have an impressive array of health promoting WFPB foods! Only one of these 5 Low FODMAP groups is derived from animal products: "lactose", which comes from milk & cheese. Dr Sadeghi encourages her patients to diligently eliminate only the "lactose" food group. She encourages her patients to retain the other four Low FODMAP food groups. And lo and behold! So many patients feel better! Milk is invariably the #1 culprit in IBS, explains Dr Sadeghi. This observation may surprise people of Indian origin because milk is revered as a health promoting food in Indian sub-continent.
