The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual's basal metabolic rate (BMR).. The estimated BMR value may be multiplied by a number that corresponds to the individual's activity level; the resulting number is the approximate daily kilocalorie intake to maintain current body weight.

As of 2011 in the US, broiler chickens has an FCR of 1.6 based on body weight gain, and mature in 39 days. [25] At around the same time the FCR based on weight gain for broilers in Brazil was 1.8. [25] The global average in 2013 is around 2.0 for weight gain (live weight) and 2.8 for slaughtered meat (carcass weight). [26]
Lean body mass (LBM), sometimes conflated with fat-free mass, is a component of body composition. Fat-free mass (FFM) is calculated by subtracting body fat weight from total body weight: total body weight is lean plus fat. In equations: LBM differs from FFM in that cellular membranes are included in LBM although this is only a small percent ...
This is why it's beneficial to switch up the weight you lift and corresponding reps as time passes. "Every eight to 12 weeks, switch between one of the following rep ranges [to] see greater long ...
