How to Use Macro, Nutrition and Hydration Estimates
Translate calorie targets into macros, interpret product data, and use hydration estimates conservatively.
Build from energy and purpose
Macro targets divide estimated energy among protein, carbohydrate, and fat. The appropriate balance depends on goals, food preferences, training, medical needs, and sustainability—not simply one universal ratio.
Read nutrition data carefully
Compare serving size, edible portion, preparation method, and data source. Brand formulations and cooked weights vary. Use several days of intake rather than drawing conclusions from one meal.
Adjust water estimates for conditions
Climate, exercise, pregnancy, illness, medications, and foods all influence fluid needs. More is not always safer; excessive water can be harmful. Use thirst and professional guidance, especially with heart, kidney, or electrolyte conditions.
