> The [2]review , led by pathologist and biomedical researcher Dudley Lamming and published in the journal Cell Press Blue , examined more than 350 studies involving humans, mice, insects, yeast, and other organisms. The review found that eating less protein, or less of certain amino acids that make up protein, may turn on body processes linked to healthier aging, as well as metabolism, the process by which the body turns food and drinks into energy...

> For adults who already get enough, eating more protein may offer little benefit, while some research suggests that eating less protein could support healthier aging... Lamming reviewed the effect of reducing protein in many body processes. One of the processes involves a hormone called FGF21. "There's an increase in a hormone called FGF21 that promotes energy expenditure [when protein intake is reduced]," Lamming said. "It essentially increases thermogenesis in your adipose tissue, so you don't just store fat, but actually burn it as fuel." This may help explain why some studies connect lower-protein diets with less body fat, better blood sugar control and a healthier metabolism. Eating less protein may also affect signals that tell cells when to grow, repair damage or recycle old cell parts. These jobs may play a role in aging.

> However, protein restriction is not the same as protein deficiency. The goal is not to deprive the body of an essential nutrient. Instead, the research raises the possibility that avoiding unnecessary excess could benefit some people who already consume enough... Before reaching for another high-protein product, a better question may be: How much protein does my body actually need?

Protein intake increases thermogenesis. This FGF21 is probably being released when protein is low because more body heat is needed when digestion and absorption aren't producing it, but we know protein-rich diets result in more total thermogenesis.

You're confusing mainstream nutrition advice with fad diets. The [1]Mediterranean diet [wikipedia.org] was proposed in 1975, and by the 1980s it was already widely embraced by mainstream nutritionists as the recommended way to eat. In the 40 years since then, that has never changed. The evidence for it has only gotten stronger with time.
Meanwhile, countless fad diets have come along, each based on some fringe theory and unsupported by solid evidence. And every time that happens, the mainstream nutritionists say, "Please ignore them. Eat a Mediterranean diet." And people like you say, "What's wrong with these scientists? Why do they keep recommending new diets that are different from the old ones?"

====
An acclaimed surgeon specializing in weight loss delivers a paradigm-shifting examination of the diet and health industry's focus on protein, explaining why it is detrimental to our health, and can prevent us from losing weight.
Whether you are seeing a doctor, nutritionist, or a trainer, all of them advise to eat more protein. Foods, drinks, and supplements are loaded with extra protein. Many people use protein for weight control, to gain or lose pounds, while others believe it gives them more energy and is essential for a longer, healthier life. Now, Dr. Garth Davis, an expert in weight loss asks, "Is all this protein making us healthier?"
The answer, he emphatically argues, is NO. Too much protein is actually making us sick, fat, and tired, according to Dr. Davis. If you are getting adequate calories in your diet, there is no such thing as protein deficiency. The healthiest countries in the world eat far less protein than we do and yet we have an entire nation on a protein binge getting sicker by the day.
As a surgeon treating obese patients, Dr. Davis was frustrated by the ever-increasing number of sick and overweight patients, but it wasn't until his own health scare that he realized he could do something about it. Combining cutting-edge research, with his hands-on patient experience and his years dedicated to analyzing studies of the world's longest-lived populations, this explosive, groundbreaking book reveals the truth about the dangers of protein and shares a proven approach to weight loss, health, and longevity.

Protein is an essential nutritional component of a healthy diet. Being in protein deficiency is actually painful. But then if you read the quote from the actual book, it has this:
> "Protein is not the key to weight loss. Animal protein is not the healthiest food we can eat. Carbs are not the enemy."
That part is true. The key to weight loss is calorie restriction over a sustained period (good rule of thumb: it takes three days of reduced calorie intake).

This part is absolutely false. Several proteins are essential amino acids, which means your body cannot synthesize them itself. They MUST be eaten. It doesn't matter how many calories are in your diet, if you do not eat those amino acids, you will have a protein deficiency.

Yes, that statement should come with an asterisk proviso. If people get all their calories from table sugar, then yes, they won't be getting any protein (as you say). But if people get all their calories from a variety of whole plant foods, then they will essentially get enough protein. So yes, there is an assumption there that people are not eating some monodiet of, say, all fruit (which is low in protein).
But all fruit and sugar are the rare exceptions of being low protein. For example, eating just potato
