Protein requirements by age: The National Academy of Medicine recommends that adults get about 0.8 grams of protein a day for every kilogram they weigh. That's about 7 grams for every 20 pounds. It suggests babies and children get a bit more, ranging from 1.2 grams per kilogram for infants...
Studies using imaging techniques such as CT or MRI to compare young and older adults suggest that at age 60, men have 14% less leg muscle than do those aged 20, and older adults will lose 0.7% to 0.8% of muscle per year. Longitudinal studies show similar results, suggesting that older ...
The egg protein requirements of men over age 60 were determined by the same techniques previously used to establish requirements of younger men, in the same laboratory. The six subjects were healthy but somewhat obese; their...
the prevalence of common psychiatric and neurologic conditions such as major depressive disorder1, schizophrenia2, Parkinson’s disease3and Alzheimer’s disease (AD)4differ by sex. Even what constitutes disease risk may differ by sex. For instance, females have significantly higher risk for myocardial...
Minimum requirements: 65.9 kg (0.8 g/kg) = 52 g Maximum requirements: 65.9 kg (1.0 g/kg) = 65 g Thus, according to the ADA, Mary needs to consume from 52 g to 65 g of protein daily. References 1.Institute of Medicine. Dietary Reference Intakes for Energy, Carbohydrate, Fiber, Fat...
Fig. 1. A–H: Bland–Altman plots of mean differences and limits of agreement between current or corrected bodyweight and FFM, stratified for BMI categories for men and female separately. In the participants with severe obesity, a notable underestimation of protein requirements in 26% is found,...
These limitations underscore the challenges of determining protein intake requirements for all adults, as well as the difficulty in differentiating needs for men versus women or for older adults versus younger adults.32 Although other methods, including carbon balance34 and amino acid indicator studies,...

Values for adult men aged 19–30 were selected for comparison with projected values in scaled plant-based diets, because these demographics encompass the majority of players profiled in the NFL [8]. 3. Results 3.1. Energy Requirements Daily energy requirements for different positions varied as ...
When protein intake is in excess of requirements, the con-stituent amino acids must be catabolized and the waste products excreted. This is associated with the production of acid equiva-lents as well as the build-up of urea and possibly other (as yet poorly characterized) metabolic toxins. ...
