50% carbs is absolute hogwash, and so is the demonization of fat (saturated fats in particular, as consumption of saturated fats is the most effective lifestyle intervention for raising HDL cholesterol, which is CVD protective). I totally agree with the previous comment that carb intakes at that level are a recipe for obesity, as well as Type 2 diabetes.
The author is "toeing the party line". Do a little research into who is funding these multiple associations and researchers she lists at the bottom of the article (I can guarantee the agricultural lobbies have a significant hand in this, as well as the pharmaceutical industry).
YouTube has a great documentary called "My Big Fat Diet", shows the results the people in a very overweight and diabetic community achieved by increasing their fat intake and reducing their carbs. Many were able to reduce if not discontinue their medications in a very short period fo time.
High fat, medium protein and low carb keeps me slim and healthy. By high fat I mean at least 50% from avocado, coconut & olive oils, nuts, organic lard and fat from pastured animals. No sugar, wheat or corn!
Interesting study findings, but not really a very good research project design if the goal was to find the optimal balance of macro-nutrients. That would require trying various ratios of all three, not just protein and fat - so really potentially misleading. For the last year, I have been eating with a much lower carb ratio - around 20-30%, fat at around 50% and protein (mostly animal) at around 20 - 30%. I have lost 60+ pounds, have way more energy, sleep better and am generally healthier - I know that is an n=1 situation - just saying, based on the article, that presumably accurately reflects the research, it didn't tell us anything useful and may have been harmful if people take-away that the proof of the research is we need to consume 50% of our diets in carbs - that was not the finding.
Why this constant obsession with just eating egg whites? OK I realise that the yolks contain more calories than the whites, but even then the average egg only contains about 70-80 calories - and what a fantastic source of all things good, not just protein but a host of other nutrients your body needs.
I just think eating only egg whites and discarding the yolks is a criminal waste of good food.
Nutritional Action, a not for profit newslettter than has no advertizing had an article about protein. Their specifics were that older people were able to avoid the sacropenia of age by consuming 30 grams of protein in one sitting.
They also mentioned that this was difficult to do, but that adding 5gs of the branched chain amino acid leucine during a meal containing less than 30 grams of protein, had the same effect on older individuals.
Something to think about if you are trying to get your protein on a restricted calorie diet.

This is so true. I consistently eat just a little bit more protein then recommended but stay within my recommended calorie range and I have experienced very little actual hunger so far. 19 lbs down, 30 lbs to go.
This is interesting-- I wish that the article and discussion of the protein/fat/carb breakdown had included a sample menu/info about how study participants were monitored to reach those percentages. Without that, this article is interesting but not particularly useful to readers.
My doctor makes me eat 50% fat, 30% protein and 20% carbs. Ick. Turns out my resting metabolic rate is abnormally high (around 3400 calories a day!) and isn't supposed to be, but they can't figure out why. It's not my thyroid...and every test just makes them scratch their heads even more.
