Some bodybuilders and weight training athletes have taken this recommendation for extra protein to extraordinary limits and well beyond any scientific recommendation.
While excessive protein seems to do no harm in healthy, active people up to a point, the risk may be more substantial for someone with kidney disease — the overweight or diabetic for example.
Excess protein beyond the requirements of the body is broken down from amino acids into ketones or glucose or energy cycle intermediates for energy, and some is converted to ammonia then urea and excreted.
The situation is encouraged by the extraordinary vigor of the powdered protein supplement industry in the weight training and bodybuilding markets.
Skim milk powder can supply all the extra protein required — and at a fraction of the price of some expensive supplement brands.
I’ll take you through an example to demonstrate the dynamics of protein requirements for weight training.
Ways of Nominating Protein Requirements
It’s possible to suggest a protein intake based on three ways to calculate possible requirements.
- Quantity per pound or kilogram of body weight per day.
- Macronutrient percentages, for example a diet of 25% protein.
- Absolute amount of protein per day, 160 grams for example.
