The role of calories in weight gain/loss is highly debated. These 7 graphs prove that calories count. This is pretty much a scientific fact at this point.

Of course calories count. That was never under contention. But "counting calories" is a failed method to approach the issue. Attempting to starve yourself works against your will power every minute of every day. Few have the obsessive compulsive disorder needed to make that work.

The better (and easily shown to work) method is to change your appetite so that you do not need to be at war against your own body. This requires, at the least, stopping the sugar cycle caused by excess carbohydrates.

On a mission to save the world from nutrition misinformation and pseudoscience...
Introduction
I'm a med student and certified personal trainer from Reykjavik, Iceland. 

My main interests in life are related to health and nutrition. You could say that it has become pretty much an obsession and I've spent the last few years reading blogs, books and research studies.

I run an evidence-based nutrition blog called Authority Nutrition. I write about health related topics from an evidence-based perspective every week.

The point of my website is to look through the literature to find evidence-based answers and solutions to common modern health problems, preferably from randomized controlled trials (the gold standard of research).

Then what I try to do is to decipher the scientific jargon and explain it in human terms, in language that both professionals and laypeople can understand.

I'm particularly interested in the low carb diet as a potential treatment for obesity, type II diabetes and metabolic syndrome... which are the biggest health problems in the world.

Other topics I cover on my site include weight loss, healthy eating, myth busting, food addiction, specific foods, sweeteners and whatever other health related topic I'm interested in exploring and discussing at the time.

Please take a moment to add me to your circles, I'd love to connect with you!

Personal

In my spare time, I like to read, hang out with family and friends, listen to music, watch movies, go for walks and lift heavy things.
