Goodson's example is that if your daily calorie requirement is 2,000 calories, and the ratio you decide on equals 30% protein, 40% carbs, and 30% fats, you can follow this formula: Protein: 2000 x ...
Macronutrients are defined as a class of chemical compounds which humans consume in relatively large quantities compared to vitamins and minerals which provide humans with energy. Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g). [2]
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.
Recommended Dietary Allowances (RDA), the daily dietary intake level of a nutrient considered sufficient by the Food and Nutrition Board of the Institute of Medicine to meet the requirements of 97.5% of healthy individuals in each life stage and sex group.

[1] As foods vary by brands and stores, the figures should only be considered estimates, with more exact figures often included on product labels.
The thermic effect of food is increased by both aerobic training of sufficient duration and intensity or by anaerobic weight training. However, the increase is marginal, amounting to 7-8 calories per hour. [1] The primary determinants of daily TEF are the total caloric content of the meals and the macronutrient composition of the meals ingested.
