    Study Notes

    Body Composition

    • Body composition describes the proportion of fat, bone, and muscle in the body. It provides a more accurate measure of health than BMI.
    • Components include water, protein, minerals, and fat.
    • Fat mass (FM) stores energy, protects organs, insulates, and regulates temperature.
    • Fat-free mass (FFM) consists of everything except fat: water, minerals, and protein (internal organs, skeletal muscle, body water).
    • Maintaining a healthy body fat percentage is crucial for long-term health.

    Methods of Measuring Body Composition

    • Skin calipers: Affordable and portable, but require expertise and are uncomfortable. Best for lean subjects.
    • Digital Image Analysis App: Simple, readily available, and inexpensive, but accuracy is questionable.
    • Dual Energy X-Ray Absorption (DEXA) Scan: Highly accurate and segmented, but expensive and requires lab access.
    • Bioelectrical Impedance Analysis (BIA): Easy, affordable, and self-operating, but accuracy depends on hydration levels.
    • Hydrostatic Weighing (HW): Not described in provided resources.
    • Computer Tomography (CT) and Magnetic Resonance Imaging (MRI): Not described in provided resources.

    Visceral Fat

    • Visceral fat (trunk/midsection fat) is positively correlated with diseases like cardiovascular disease, diabetes, and high blood pressure.

    Nutritional Needs

    • Focus on balanced meals with fruits, vegetables, whole grains, and lean protein.
    • Portions should be controlled, and protein is important for muscle growth and repair.
    • Limit processed foods, sugary drinks, and unhealthy fats (saturated fats).

    Macronutrients

    • Macronutrients (carbohydrates, fats, proteins) are needed in large quantities for energy and bodily functions.
    • Carbohydrates: Provide energy. Choose complex carbs (starches) over simple carbs.
    • Fats: Help with satiety and vitamin absorption. Limit saturated fats and trans fats. Choose unsaturated fats (nuts, fish, vegetable oils).
    • Proteins: Build and repair tissues. Animal products (meats, dairy) provide all essential amino acids; vegetables may be lacking one or more essential amino acids. Choose lean protein sources.
    • Energy Values: 1 gram of protein/carbs = 4 calories; 1 gram of fat = 9 calories.

    Micronutrients and Water

    • Micronutrients (vitamins and minerals) are needed in small amounts but are essential for bodily functions.
    • Water: Makes up 50-60% of body weight. Essential for nutrient transport, bodily functions, and temperature regulation. Aim for at least 8 cups of 8 oz water daily.
    • Vitamins: Crucial for various bodily functions. Vitamin A for vision and immune function; Vitamin B for energy release; Vitamin C for immune system and collagen synthesis; Vitamin D for calcium absorption. Numerous sources for each vitamin.
    • Minerals: Maintain fluid balance and function in bone health. Calcium (dairy products), iron (red meat, spinach, apricots), fiber regulate bowel movements and bind fats, aiding in prevention of reabsorption into the body.

    Food Labeling

    • Read food labels to understand nutritional content, identify added sugar, manage portions, and avoid allergens.
    • Key label elements include serving size, calories, nutrients, and % Daily Value.
    • % Daily Value of 5% or less is low, 20% or more is high in a nutrient.

    Supplements

    • Supplements offer concentrated nutrients beyond a balanced diet.
    • Supplements might be used for athletic performance, appearance, meal replacement, or for nutrient deficiencies.
    • However, supplements are not regulated and uncontrolled use can be problematic.
    • A balanced diet is the priority. Consult a professional for performance goals.

    Energy Balance

    • Energy balance refers to calorie intake versus calorie expenditure.
    • Maintaining weight involves equal energy intake and expenditure.
    • Positive energy balance leads to weight gain; Negative energy balance leads to weight loss.
    • Factors include diet, physical activity, and basal metabolic rate (BMR).

    Exercising

    • Exercise is crucial for changing or maintaining body composition.
    • Resistance training (strength training) can increase muscle mass.
    • High-intensity exercise reduces visceral fat.
    • Proper form, gradual progression, and consultation with professionals are important.
