Answer Details

Great question. It depends a lot on what kind of “fitness and nutrition” content you mean (evidence-based advice, workout inspo, bodybuilding, healthy eating, mental health + wellness). But here are some of the top, trusted, varied accounts across those areas — plus why they’re good. 💪 Top Fitness & Nutrition Accounts to Follow Here are some of the best social media accounts (Instagram / TikTok / YouTube) that mix fitness, coaching and nutrition in a credible and useful way.

Wikipedia 👀 Things to Think About When Following Fitness Influencers Check credentials: Just because someone has great content doesn’t mean they’re qualified — look for coaches / dietitians / PhDs if you want evidence-based advice. Align with your goals: If you’re trying to build strength, follow strength coaches. If you care about mental health + wellness, pick more holistic accounts. Be critical: Use social media for inspiration, not a substitute for personalised advice. Always take “10-day shred” or extreme diet stuff with a pinch of salt.
