Research has suggested that we need at least 15-25 grams of protein at each meal to adequately stimulate muscle protein synthesis. 13Īim for at least 20 grams of protein at each meal Therefore, some experts in protein research believe that older people need a minimum of 1.2 grams per kg daily to counteract muscle loss and other age-related changes. Muscle protein synthesis declines from the third decade, and the rate of decline increases from age 60 years. 11 Importantly, this must be done under strict medical supervision. On the other hand, individuals who follow keto diets for therapeutic purposes – for instance, for management of certain cancers – may want to aim for the lower end of the range, between 1.2 and 1.5 grams per kg of body weight per day. 10 This would include people who are underweight or healing from illness, injury, or surgery. In some cases, an even higher protein intake of more than 2.0 grams of protein per kg of body weight may be beneficial, at least temporarily. (The chart above represents around 1.6 g/kg.) We recommend aiming for the higher end of the range noted earlier in this section, between 1.6 g/kg and 2.0 g/kg. If you want to lose fat mass while building or maintaining lean mass, you may want to maximize your nutrition/protein per calorie. You can use the following guidance to customize your own protein intake. This chart represents about the middle of the range of 1.2 to 2.0 g/kg range. Otherwise, you can use your height – and the chart below – to estimate how much protein you should aim to eat on most days. If you’re near your ideal body weight or very muscular, use your actual weight (in kilograms) to calculate your protein needs. Protein intake within this range has been shown to preserve muscle mass, improve body composition, and provide other health benefits in people who eat low-carb diets or higher-carb diets. Taking into account the different positions among keto and low-carb experts, we recommend a protein intake of 1.2 to 2.0 grams per kg of reference body weight for most people. Guidelines for individualized protein intake 7 And protein can also limit the deposition of fat in the liver under obesigenic conditions such as overfeeding with fructose. 6įinally, there is growing evidence that increasing protein in the context of a low-carbohydrate diet lowers liver fat and blood glucose in the absence of any weight change. 5 Your body also burns more calories digesting protein compared to fat or carbs. This might be because protein can reduce appetite and prevent overeating by triggering hormones that promote feelings of fullness and satisfaction. In addition, both clinical experience and scientific studies suggest that getting enough protein can help make weight control easier. Your body depends on a continuous supply of amino acids to make these vital compounds. Likewise, most enzymes in the human body are proteins. Many important hormones – including insulin and growth hormone – are also proteins. Although the protein turnover in these structures occurs more slowly than in muscle, new amino acids are required to replace those that become old and damaged over time. Maintaining healthy skin, hair, nails, and bones as well as our internal organs.Consuming adequate dietary protein helps prevent muscle loss, and – when coupled with resistance training – promotes muscle growth. The protein in your muscles is normally broken down and rebuilt on a daily basis, and a fresh supply of amino acids is needed for muscle protein synthesis, the creation of new muscle. These are just a few of protein’s important functions: After you eat protein, it is broken down into individual amino acids, which are incorporated into your muscles and other tissues. Protein is a major component of every cell in your body. Keto-friendly plant protein sources include tofu and soy-based products, as well as most nuts and seeds, although some are higher in carbs than others. Keto-friendly animal protein sources include meat, poultry, seafood, eggs and cheese. Plant proteins also contain each of the 9 essential amino acids but often have quite a bit less of one of the essential amino acids compared to animal protein. Animal protein sources do contain the essential amino acids in consistently high amounts. 2Īnimal protein is commonly referred to as “complete protein” because it contains all 9 essential amino acids, with an implication that plant proteins are therefore “incomplete.” The reality is more nuanced. These are known as the essential amino acids, and they must be consumed in food on a daily basis. Although your body is capable of making just over half of the 20 amino acids it needs, there are nine that it can’t make. Protein is made up of several smaller units called amino acids.
