Answer Details

Short answer: there’s no single “best” list, but there are some consistently high-quality, mostly evidence-based creators. Here’s a starter pack you can pull from depending on what you want (muscle, general fitness, or nutrition). Strength & Hypertrophy / Gym Training 1. Jeff Nippard – YouTube, IG Natural bodybuilder with a BSc in biochemistry who breaks training and nutrition down using research, not bro-science. YouTube Great if you like long-form breakdowns (program design, volume, technique). 2. Sohee Carpenter (@soheefit) – Instagram, YouTube PhD, CSCS; focuses on realistic, sustainable strength training and behavior change, especially for women. Instagram +1 Lots of myth-busting and content about habits, binge–restrict cycles, etc. 3. Renaissance Periodization (RP Strength) – YouTube, IG Team of PhDs and high-level coaches (e.g., Dr Mike Israetel) explaining hypertrophy, fat loss, and periodization in a pretty rigorous way. 4. Squat University – IG, YouTube, TikTok Dr Aaron Horschig, physical therapist; excellent for form checks, mobility, and staying pain-free while lifting. General Fitness, Form & Beginner-Friendly Stuff 5. Natacha Océane – YouTube, IG Science-leaning, varied training (strength, conditioning, athletic-style workouts). Often explains why she programs things the way she does. 6. Caroline Girvan – YouTube If you want straightforward follow-along strength workouts at home with dumbbells, she’s hard to beat. 7. MegSquats (Meg Gallagher) – YouTube, IG Powerlifting-focused but very beginner-friendly; lots on learning the big lifts, body image, and women getting stronger. Evidence-Based Nutrition & Dietitians Look for “RD” or “RDN” (registered dietitian) in bios – that’s usually a good sign. 8. Jessica Knurick, PhD, RD (@drjessknurick) – IG, TikTok Public health expert going viral for debunking wellness misinformation and explaining research in plain English. Vox 9. Sophie Medlin (@sophiedietitian) – Instagram UK registered dietitian; lots on gut health, IBS, and realistic eating patterns, plus myth-busting around fad diets. Instagram 10. Chicago Dietitian (@chicago.dietitian) – Instagram Licensed RDN promoting a flexitarian, middle-ground approach to eating – very anti-all-or-nothing, practical for normal people. SuperProfile 11. Alan Aragon – Instagram, Substack Veteran evidence-based nutrition researcher and coach; more text-heavy, but excellent if you like digging into studies. FeedSpot for Influencers How to choose who you should follow Use this quick filter: Credentials & transparency For nutrition: look for RD/RDN, MD, or PhD in a relevant field. For training: recognized certs (CSCS, PT) + clear experience are good, but results and reasoning matter too. Red flags (probably unfollow if you see): “One weird trick” or secrets. Demonizing single foods (“seed oils are killing you,” “never eat carbs after 6pm”). Selling expensive supplements or programs as the only solution. Constant before/after shots but no explanation of methods. Green flags: They say “it depends,” talk about sleep/stress/lifestyle. They change their mind when new evidence appears. They emphasize consistency and habits over hacks. If you tell me your main goal (e.g., “build muscle at home with dumbbells,” “lose 10–15 lb without tracking calories,” “eat better as a vegetarian”), I can narrow this down to a tiny, goal-specific follow list so your feed is actually useful instead of overwhelming.
