I'm too lazy to do research, but I have read articles that low carb is basically restricting calories also. You eliminate many food groups so if you were eating lots of that stuff before, i.e. sweets, breads, pasta, you no longer do so and lose weight.
Also, as far as research, unless an article is peer-reviewed then one needs to take it with a grain of salt. This goes for any topic, not just weight loss. When I was going for my Masters and had to write a thesis, all articles had to be peer-reviewed.
If low-carb works for you, that is great!, it worked for me for about six months, and then I couldn't stand not eating any carbs at all. Losing weight is easy, keeping it off is what is the hard part. If any of us had the secret, we would be billionaires.
My goal for 2014 is Fifty Pounds in Fifty Weeks began Christmas 2013
