This is something health coaches, nutritionists, and scientists (trained in biology, chemistry, or endocrinology, as opposed to conventional medicine) have said for decades.
The notion that all calories are the same; that calories-in (consumed) compared to calories-out (burned) is the end-all-be-all in terms of bodyweight; is archaic and damaging to our public’s health.
Just last week, a study was published showing the results of consuming a high-protein diet. However, fat and carb intake was held constant between the two groups, meaning the high-protein group was consuming over 500 extra calories a day.
After 8 weeks, there was no difference between the two groups, in terms of bodyweight or body composition.
1.) Excess calories coming from protein may not lead to weight gain. This may be invaluable for individuals trying to lose weight considering that protein is the most satiating macronutrient.
2.) It is not necessary to consume extra protein to gain muscle. This is most useful for individuals trying to put on muscle, since protein can be the most expensive macronutrient.
I’ve always suggested my clients try to consume one gram of protein per pound of bodyweight. This has been the standard for athletes and performance-oriented individuals for decades. Unfortunately, the general public has been convinced that protein is bad for the kidneys or the body as a whole.
There are many studies showing that individuals with kidney impairment have issues with high-protein diets…but these results have never been replicated with healthy populations.
The way major food companies produce and prepare meat will make it harmful to our body (and the environment). Feeding corn to cows literally becomes a race against the clock to see if the cow can grow fat enough to slaughter, before it dies of indigestion and infection. At the same time, grain-feeding will skew the omega-3 / omega-6 ratio, increasing the amount of inflammatory omega-6 found in the animals fat.
However, if cows, or any animal for that matter, are given enough land to wander about, and a natural diet for them to freely consume, their meat will not only be healthy for us, but may be the most beneficial food we can consume.
So, if your goal is to reduce body-fat, and you plan to achieve weight-loss using calorie restriction, make sure you are not reducing your protein intake. And keep in mind, if you are hungry or have trouble staying full, have a few extra bites of protein.
Alternatively, if you are trying to increase muscle mass, consume 1g protein per 1lb bodyweight, but, after that save your money and get extra calories from natural carbs or healthy fats. Scoops of expensive protein powder or additional pounds of chicken breast may not make a significant difference.
This study is just one more step towards correcting our understanding of food and the human body. Nothing that comes from nature, meant to give us sustenance, is automatically bad for us. It is only when we tinker with nature, maximizing production while minimizing cost, that problems arise.
