The 10 Most Credible Health and Fitness Bloggers You Can Trust


*Learn which health and fitness bloggers you can trust.*

Here’s the sad truth about most health and fitness blogs:

For every 10 minutes you spend reading, watching, and listening, maybe 1 will be spent consuming accurate information.

After an hour of surfing the internet, you end up with a small collection of random facts, buried underneath a pile of garbage.

Luckily, there’s a simple way you can solve this problem.

Find the experts you can trust. Follow their sites, read their articles, and ignore the rest.

This is a great example of the 80/20 rule. By following the 20% of health and fitness bloggers who know what they’re talking about, you’ll get at least 80% of the knowledge you’ll ever need to be healthy. You’ll also avoid at least 80% of the pseudoscience and misinformation on the internet. (By following the bloggers in this article, the ratio is more like 99/1 — you’ll get 99% of the info you need, and avoid 99% of the fluff).

The following 10 experts consistently produce the most accurate health and fitness content on the web.

These are the first people you should turn to when you’re confused about what diet to follow, how to structure a workout, whether or not you should get vaccinated, or almost any other controversial health topic. They’ll set you on the right path.

### 1. Alan Aragon


The world needs more people like Alan Aragon.

Whether he’s debunking fructose alarmism, exposing unfounded supplement claims, or setting the record straight on how often you really need to eat, Alan brings the same level of skepticism, poise, and unbiased curiosity to every subject.

Much of his writing appears on other sites such as Men’s Health, WannaBeBig, and LiveStrong, but his ongoing magnum opus is the Alan Aragon Research Review. Each month, he releases what is easily the most accurate, critical, and relevant newsletter on the latest health and fitness research. You can download a free sample issue here.

Alan’s also got an impressive set of credentials, works as a nutrition and training coach to professional athletes, and has over 20 years of experience as a fitness professional. Plus he’s a funny and nice dude.

## 2. James Krieger


The science of weight loss is a confusing topic. Luckily, people like James Krieger are here to help.

James runs a membership site called Weightology Weekly, where he dissects the latest research on weight loss. His free articles on insulin and fructose are especially well done, and will give you an idea of the kind of quality you can expect.

His articles are easy to read, his tone is inclusive and open minded, and he takes the approach of an educator rather than a guru.

James has also spent years in the trenches as a weight loss consultant. He was once the research director for a corporate weight management program that treated over 400 people per year, with an average weight loss of 40 pounds in 3 months. He is also an academic researcher who’s work has been published in several prestigious medical journals.

### 3. Alex Hutchinson


What do you get when you combine a physicist, exercise scientist, national level runner, and award winning journalist?

Alex Hutchinson, that’s what.

Alex writes some of the most user friendly, up-to-date, and accurate articles you’ll ever read on exercise science. None of his articles generally stretch more than 500-1,000 words, which also makes them perfect for a quick fix of knowledge.

He mostly writes about endurance sports, but nothing is off-limits. He’s covered topics such as whether or not yo-yo dieting damages your metabolism, how to tell if you might be overtraining, and why dehydration might not cause muscle cramps.

Alex mainly writes about the science of exercise on his Runner’s World blog, Sweat Science, and on the Globe and Mail. He is also a contributing editor at Popular Mechanics and a senior editor at Canadian Running magazine.

### 4. Stephan Guyenet


Stephan Guyenet has written some of the most consistent, lay friendly, and useful health information on the web for over a half decade.

Stephan is perhaps best known for his research on appetite control, food reward, and other mechanisms that contribute to obesity. His most popular article is probably “The Carbohydrate Hypothesis of Obesity: a Critical Examination,” where he debunks the idea that carbohydrates are more fattening than other foods.

You can find more of Stephan’s work on his website,

### 5. Paul Ingraham


You’re probably don’t give much thought to the science of every day aches and pains — until you get injured.

That’s when it’s time to find Paul Ingraham.

Paul is the founder and editor of, a website that takes a skeptical approach to the prevention and treatment of common aches, pains, and injuries.

Instead of promising miracle cures based on dubious or nonexistent research, Paul guides you through all of the available data so you can make informed decisions about your treatment options. His articles are clear, fun, well-referenced, and frequently updated.

Paul has also gone to great lengths to make a truly remarkable and unique footnote system for his site. It makes it easier to fact-check his work and do your own research; and for him to present the evidence in a way you can understand and use.

Paul even writes articles criticizing his own books when new evidence arises that questions his previous beliefs. It’s hard to find someone more devoted to the truth.

If you suffer from back pain, neck pain, knee pain, strained muscles, or almost any other common ache or pain, you should check out Paul’s site. His articles on stretching, massage for reducing inflammation, and barefoot running are especially eye opening.

### 6. Lyle McDonald


There are few people in the fitness world more well read and reliable than Lyle McDonald.

His diet and training advice has helped thousands of people lose fat, gain muscle, and perform better.

His website, Body Recomposition, has over 2,000 free articles on topics mostly related to fat loss and muscle gain, but it doesn’t stop there. He’s also written about how to train for endurance sports, perform exercises with perfect technique, avoid overtraining, and much more.

Lyle doesn’t update his site as often as he used to, but he’s written enough articles to keep any health nut busy for a long, long time.

### 7. Anthony Colpo


A walking B.S. detector is one way to describe Anthony Colpo.

The author of The Great Cholesterol Con and The Fat Loss Bible, Anthony is a health journalist and independent researcher with an impeccable ability to separate fact from fiction.

His articles and books are well referenced, funny, and easy to read. A few good places to start are his articles on why low carb diets aren’t a great plan if you’re training a lot, using caffeine to boost athletic performance, the optimal number of sets for muscle growth, and why cholesterol does not cause heart disease.

### 8. Dr. Harriet Hall


After a career as a U.S. Air Force flight surgeon and family physician, Dr. Hall set her sights on debunking pseudoscience and medical quackery.

She brings a credible and critical view to controversial topics such as vaccines and autism, unproven anti-aging therapies, and at-home blood testing kits.

Most of Dr. Hall’s work is published on the Science Based Medicine bog, of which she is one of the editors and founders. You can also find her writing on her personal website and Skeptic Magazine.

### 9. Dr. Steven Novella


Few people have done more to squelch pseudoscience and champion critical thinking than Dr. Steven Novella.

Dr. Novella’s main job is as an academic clinical neurologist at the Yale University School of Medicine.

On the side, he’s an active member of the skeptical community, the executive editor of the Science-Based Medicine blog, and the host and producer of the popular podcast The Skeptics’ Guide to the Universe .

Dr. Novella’s personal blog, Neurologica, “covers news and issues in neuroscience, but also general science, scientific skepticism, philosophy of science, critical thinking, and the intersection of science with the media and society.”

He’s written about how we’re fooled by “nocebos,” toxins and autism, and even the Hobbit. His articles tend to be lay-friendly, yet well researched and referenced. Dr. Novella also updates his blogs regularly, so you won’t run out of reading material any time soon.

You can find most of Dr. Novella’s writing on the Science Based Medicine blog, on Neurologica blog, and on the James Randi Foundation website.

### 10. Dr. Mark Crislip


“Infectious” might be the best way to describe Dr. Mark Crislip’s work.

Dr. Crislip is an infectious disease doctor who spends his free time debunking “Supplements, Complementary and Alternative Medicine,” or what he likes to call “SCAM.”

His podcast, the QuackCast, is filled with year’s of content, covering craniosacral therapy, acupuncture, homeopathy, chiropractic, flu vaccine myths, and everything else that threatens science in medicine.

If you’ve ever wanted to hear a medical professional call something “profoundly moronic” or “mind-bogglingly stupid,” and have the evidence to back it up, you’ll love the QuackCast.

You can find Mark’s writing on the Science Based Medicine blog, on his personal site,, and by subscribing to his podcast on iTunes.
