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.
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.
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.
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.
