Cheat Sheet
- Basal Metabolic Rate (BMR) and the Mifflin - St Jeor Equation -
BMR is the minimal energy requirement at rest, accounting for vital functions only. The Mifflin - St Jeor formula - endorsed by the Academy of Nutrition and Dietetics - calculates BMR as: for men, 10×weight(kg)+6.25×height(cm)−5×age(years)+5; for women, the same expression minus 161. For example, a 70 kg, 175 cm, 30-year-old man has a BMR of about 1673 kcal/day (NIH).
- Total Daily Energy Expenditure (TDEE) and Activity Multipliers -
TDEE builds on BMR by adding an activity factor; for instance, sedentary×1.2, lightly active×1.375, moderately active×1.55 (ACSM guidelines). Multiply BMR by the appropriate factor to estimate daily calories - for example, 1673 kcal×1.55≈2594 kcal for moderate activity. This core concept is invaluable when tackling a daily calories quiz or calorie intake quiz.
- Macronutrient Caloric Values and the 4 - 4 - 9 Rule -
Each gram of carbohydrate and protein supplies 4 kcal, while fat delivers 9 kcal (USDA). On a 2000 kcal diet, 50% carbs equals 1000 kcal or 250 g of carbs - an easy calculation using 4 - 4 - 9 as your mnemonic. Tracking these values sharpens your accuracy in nutrition facts quizzes and meal nutrient quizzes.
- Energy Density versus Nutrient Density -
Energy density measures calories per gram, while nutrient density assesses micronutrients per calorie (Harvard T.H. Chan School of Public Health). Foods high in water and fiber - like cucumbers - have low energy density and high satiety, unlike calorie-rich nuts. Remember "Water + Fiber = Weight Loss Wins" as a simple mnemonic for balanced meal planning.
- Accurate Tracking Methods and Common Pitfalls -
Digital food scales and reputable apps (Cronometer, MyFitnessPal) reduce error when recording portions and calories. Be mindful of hidden calories in sauces and drinks, and cross-check against the Nutrition Facts label to avoid underestimation. Practicing portion estimation with your hand (e.g., palm=fat, fist=carbs) boosts confidence before any how many calories should i eat in a day quiz challenge.
