Casein is a highly underrated type of protein. It is digested very slowly and leads to a slow release of amino acids into the bloodstream. Studies show that it is effective for:

- Muscle gain.
- Increased strength.
- Maybe even fat loss, with one study showing tripled fat loss compared to a control group.

I've sometimes mixed 2 scoops of chocolate casein in a bowl with water and a tablespoon of heavy cream. Then I add it to the fridge for 5-6 minutes and then take out. It is absolutely delicious, tastes similar to frosting or ice cream.

Just like whey protein, casein is derived from dairy. It is a slow-digesting, high-quality protein with numerous benefits for muscle gain and health.

Story
Tagline
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.
