Sure, low-carbohydrate regimens are similar, but they are also vastly different.   Carbohydrate-restricted diets can vary in carbohydrate allowances from less than 20 grams to 130 grams daily.  Because the weight loss plans vary so much, I would argue that judging them as a group is unfair when they are clearly different.  Despite this, experts continue to vilify higher protein plans as a group.  So, what does the research show?  

In this article[2], the physicians defined low-carb diets at a highly variable level of carbohydrates. The study reports that previous articles have reported that “low-carb comprises less than 45 percent of daily calories from carbohydrates.”  I would not consider 45 percent to be low in carbohydrates.  In fact, I would think 45% to be a high level.  

Research on Carbohydrate Reduced Diets:

1.

   Protein is more filling than carbohydrates. Although the study population is small, it did indicate that among 18 males, the protein was more satiating than carbohydrates, and the subjects were less hungry after protein meals and ate less[3].

2. Low-carb regimens are decent alternatives to the standard low-fat diet. One study examined 332 moderately obese subjects and found that the low-carb and Medeteranien groups lost 4.7 and 4.4 kgs versus 2.9 kgs on the low-fat diet[4].
3. Low-carb diets may result in more weight loss than a low-fat regimen. One study looked at 1,415 patients on either a very low-carb or a low-fat plan.  The researchers found that the very low-carb plan lost more weight during this study[5].

There are plenty more studies that both indicate for and against low-carbohydrate plans. I have recommendations based on my review of the data.  I do not think the studies are clear enough to recommend low-carb for everyone,  but clearly, there might be benefits for some dieters.

Recommendations on Low-Carb Diets:

1. Individualize your nutrition plan. Not everyone is meant to be on a low-carb diet. Pick a regimen that fits your lifestyle. I could not survive vegan meals alone and would be miserable if I tried.  There is a reason the maker gave us canines, and I do not believe it was to rip apart broccoli.
2. Low-carb might increase short-term weight loss. If you can tolerate a  restricted or reduced carbohydrate diet, consider it an option in your body mass reduction plans.  I do believe it may work better in some than others.  It is not perfect for everyone, so you should pick a diet that works for you.
