  1. Food and Body weight Discuss between hunger and appetite. Summarize why eating a healthy breakfast is important. Describe the balance between food intake and exercise and the effects of body weight. Describe how obesity is linked to poor health.

  2. Hunger and Appetite Hunger: the body’s physical response to the need of food. Appetite: The desire , rather than the need to eat certain foods. The example of eating ice-cream with friends after eating a big meal is appetite not hunger.

  3. The amount and type of food you choose is affected by: • Smell and taste • Mood • Family traditions and ethnic back ground • Social occasions • Religious traditions • Health concerns • Advertising • Cost and availability

  4. Food and Energy…Again Remember carbohydrates, fats, and protein are energy giving nutrients. Carbs and protein have 4 calories per gram and fat has 9 per gram. Calories: the units that measure food energy. Equal to the amount of heat required to raise one gram of water one degree Celcius.

  5. Breakfast When you wake up, generally you have not eaten in 10 to 12 hours. If you skip breakfast, then maybe 16 hours without food until lunch time. With this one must depend on stored energy to fuel your body and brain. By eating breakfast your body gets quick energy to feed the body and brain in school or work. Meals with lots of fat and protein makes us feel full longer than meal only of carbohydrates. Mixing all three is probably the best choice.

  6. Balancing Body Weight The amount of food you need depends on how much energy your body is using. Most of the food energy the body needs is for basic functioning: breathing, circulating blood, and growing. Basal metabolic rate is the minimum of energy needed to keep you alive when you are rested, fasted state, such as when you wake up in the morning.

  7. When the amount of food energy you take in is equal to the amount of energy you use, you have energy balance. Eating more or less than what you need with put you out of balance. Eating more increases fat stores, gain weight. Eating less decreases fat stores, lose weight. Overweight: generally means being heavy for height or 10% or more above your ideal body weight. Obese: generally means being more than 20% above ideal body weight.

  8. Determining Ideal Body Weight Ideal % fat for Girls and boys under 18 is 17% and 12%. For men and women it is 15% and 20%. Calculating Ideal Body Weight: • Fat weight…Body weight x % body fat • Lean Body weight…Body weight – fat weight. • Ideal % fat…17% for girls and 12% fro boys. • Ideal body weight… Lean Body Weight 1.0- Ideal fat %
