Indeed, physique athletes such as bodybuilders have long relied on the rule of 1 gram of protein per pound of body weight – or 150 g per day for a 150 lb individual.

make you feel full longer) and consequently help you manage your body weight. The body needs its protein stores to be continually replenished, which means that you should consume moderate amounts of protein at regular intervals – which just happens to be an important Precision Nutrition guideline.Ĭonsuming more protein may help maintain an optimal body composition (in other words, help you stay leaner and more muscular) and a strong immune system, good athletic performance, and a healthy metabolism. The take-home here is that you can’t simply eat a 16-pound steak (a la Homer Simpson consuming “Sirloin A Lot”) once and be done with it. Image source: DJ Millward, The Metabolic Basis of Amino Acid Requirements. Notice how the upper limit never increases the amount of protein in the body just cycles up and down as we eat or fast. As the graph below shows, the body’s protein stores fluctuate over the course of a day. We can only store so much protein at one time. 3 In other words, we need a small amount of protein to survive, but we need a lot more to thrive. The most we need to consume throughout the day for protein synthesis probably isn’t more than 1.4 – 2.0 g/kg.īeyond the basics of preventing deficiency and ensuring a baseline of protein synthesis, we may need even more protein in our diets for optimal functioning, including good immune function, metabolism, satiety, weight management and performance.
These suggested protein intakes are what’s necessary for basic protein synthesis (in other words, the creation of new proteins from individual building blocks). 2 Our hypothetical 150 lb (68 kg) person would thus need about 95-135 g of protein per day. It’s not necessarily optimal, particularly for people such as athletes who train regularly and hard.įor people doing high intensity training, protein needs might go up to about 1.4-2.0 g/kg (or around 0.64-0.9 g/lb) of body mass. However, this amount is only to prevent protein deficiency. For instance, a 150 lb (68 kg) person would consume around 54 grams a day. The basic recommendation for protein intake is 0.8 grams per kilogram (or around 0.36 g per pound) of body mass in untrained, generally healthy adults. How much protein you need depends on a few factors, but one of the most important is your activity level.

It can also help to liberate free fatty acids from adipose tissue – another way to get fuel for cells and make that bodyfat do something useful with itself instead of hanging lazily around your midsection! How much protein do you need? This causes the liver to break down stored glycogen into glucose for the body. 1 Glucagon is released when blood sugar levels go down. Protein helps replace worn out cells, transports various substances throughout the body, and aids in growth and repair.Ĭonsuming protein can also increase levels of the hormone glucagon, and glucagon can help to control body fat. Since our bodies need proteins and amino acids to produce important molecules in our body – like enzymes, hormones, neurotransmitters, and antibodies – without an adequate protein intake, our bodies can’t function well at all. (Think of it like a Vegas buffet of protein for the cells.)
The amino acid pool in the bloodstream readily trades with the amino acids and proteins in our cells, provides a supply of amino acids as needed, and is continuously replenished. This pool is a storage reserve of amino acids that circulate in the blood. Why is it important to get enough protein?ĭuring digestion, the body breaks down the protein we eat into individual amino acids, which contribute to the plasma pool of amino acids.
