Cheat Sheet
- Basal Metabolic Rate (BMR) -
Your BMR is the number of calories your body burns at rest and sets the foundation for calorie needs in a calorie quiz or nutrition quiz setting. Use the Mifflin - St Jeor equation (Women: BMR = 10×weight(kg)+6.25×height(cm)−5×age(yr)−161; Men: BMR = 10×weight(kg)+6.25×height(cm)−5×age(yr)+5) as recommended by the NIH for accurate estimates and practice sample calculations.
- Macronutrient Caloric Values -
Each gram of carbohydrate and protein yields 4 calories, fats provide 9 calories per gram, and alcohol contains 7 calories. A handy mnemonic for your food calorie quiz is "CP4 F9 A7" to recall Carbs(4), Protein(4), Fat(9), Alcohol(7).
- Energy Density & Satiety -
Foods low in energy density (like vegetables and broth-based soups) fill your stomach with fewer calories, which is key knowledge for a nutrition quiz. Harvard T.H. Chan researchers show that increasing high-volume, low-calorie foods helps manage hunger without overconsuming calories.
- Fat-Soluble vs Water-Soluble Vitamins -
Fat-soluble vitamins (A, D, E, K) store in body tissues, while water-soluble vitamins (B-complex and C) must be replenished regularly through diet. A memory trick for your vitamin quiz is ADEK for fat-solubles and "Be C Wise" for B and C vitamins. The NIH Office of Dietary Supplements notes that understanding absorption and daily requirements prevents deficiencies and toxicities.
- Interpreting Nutrition Labels -
Reading a nutrition label correctly helps you answer questions in a food calorie quiz by focusing on serving size, calories per serving, and % Daily Value (%DV). The FDA recommends starting with the servings-per-container line to avoid underestimating intake and then checking macronutrients and vitamins listed. Practicing with real labels from snacks or beverages makes you confident during a health and nutrition quiz.
