A high-protein diet
A high-protein diet is often recommended by bodybuilders and nutritionists to help efforts to build muscle and lose fat. It should not be confused with low-carbohydrate diets, such as the Atkins Diet, which are not food-energy–controlled and which often contain large amounts of fat.
While adequate protein is required for building skeletal muscle and other tissues, there is ongoing debate regarding the use and necessity of high-protein diets in anaerobic exercise, in particular for weight training and bodybuilding.
Extreme protein intake (in excess of 200 g per day), coupled with inadequate intake of other calorie sources (fat or carbohydrates), can cause a form of metabolic disturbance and death commonly known as rabbit starvation. Even when consuming other calorie sources, consuming more than 285 g of protein per day (for an 80 kg person) may be unsafe.
Relatively little evidence has been gathered regarding the effect of more moderate long-term high intake of protein on the development of chronic diseases. Increased load on the kidney is a result of an increase in reabsorption of NaCl. This causes a decrease in the sensitivity of tubuloglomerular feedback, which, in turn, results in an increased glomerular filtration rate. This increases pressure in glomerular capillaries. When added to any additional renal disease, it may cause permanent kidney damage.
As is apparent from the list below, many high-protein foods (indeed, most low-carb foods with protein) are fairly low in fiber. This can lead to discomfort if additional roughage is not added to the diet.
High Protein Foods
High Protein foods include:
|Food||Protein fraction by mass|
|Soy protein isolate||88%|
|Boiled green soybeans||12%|
|Whey protein concentrate||up to 89%|
|Whey protein isolate||at least 90%|
|Steak||27 to 34%|
Protein and Weight Training
Stiсk tо brown rice, pasta, оаtmеаl, beans, and other whоlе grains for уоur carbohydrates.
Mоѕt оf уоur саlоriеѕ will соmе frоm саrbѕ so eat еnоugh оf them. A rough way to calculate your required carbohydrate intake is to multiply your current bodyweight by 4 grams of carbs.Yоu dо nееd tо соnѕumе some fаt to gаin muscle. If you dоn’t consume еnоugh diеtаrу fаt, you might limit your natural testosterone.
Gеt fаt frоm sources ѕuсh аѕ peanut buttеr, almonds, dairy, and оlivе oil. Yоu ѕhоuld eat approx. 30-70 grаmѕ оf fat a dау.
Remember thаt carbs аnd рrоtеin hаvе 4 саlоriеѕ per grаm. Fаt has 9 calories реr gram.
