Keto fat protein carb percentages8/10/2023 ![]() 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.
