If You're Looking For Legit Health and Fitness Advice on Instagram, Here's Who to Follow

There's a lot of information on the internet, both good and bad; and on social media, you'll find so-called "experts" touting their ability to help you get healthier, more lean, and ready to conquer your goals. It's important to know that you can't trust everything you read online. Plus, once you find someone that looks and sounds like they know what they're talking about, you should be vetting them for the right certifications.

For example, all registered dietitians are nutritionists, but not all nutritionists are registered dietitians. Both know about nutrition, though dietitians have gone through certain requirements in order to be called RDs or RDNs (registered dietitian nutritionist). Some certified nutritionists (CNs) can have as high as a master's degree, but there are a number of states that don't require formal training or licenses. So, "nutritionist" isn't as regulated of a term in the US and anyone can call themselves one without proof of qualifications. If you're looking for a professional to give you a full diet plan for weight-loss or specific health reasons, registered dietitians are best.

In terms of exercise advice, certified personal trainers should be your go-to sources. Many people tout themselves as online coaches, but a credible CPT will have a certification from trusted organizations such as the National Academy of Sports Medicine (NASM), the American Council on Exercise (ACE), the American College of Sports Medicine (ACSM), the International Sports Sciences Association (ISSA), or Board of Certification For the Athletic Trainer (BOC). These are just a few, and you can also find trainers who've gone the extra mile to receive a CSCS certification in strength and conditioning. Read more about these certifications here. Ahead, check out six experts who are both RDs and CPTs, where to follow them on Instagram, and why we like their accounts so much.
