To calculate the BMR for a 76 kg female, you would do the following:
0.9 kcal/kg body weight per hour x 76 kg x 24 hr/d = 1,642 kcal/d.
3500 calories is
1 lb of fat
To calculate her activity cost for light activity, you would do the following:
1,642 kcal/d x 0.5 = 821 kcal/d.

additive
factors that change BMR
age, fasting, exercise
A portion of the food we eat is not digested and absorbed, so it ends up in the stool. The physiological fuel value refers to the
amount of energy our body actually gets when we eat a food item.
in a bomb calorimeter, the food in question is burned, and heat is given off while the water heats up. From this change in temperature in the water chamber, the total or maximum number of calories in the food c
an be calculated. Since we are not taking into account how many calories our body is able to absorb from the food (physiological fuel value), a bomb calorimeter is solely determining the total potential energy that food item contains.
measure:
at rest, fasted 12 hours, 24 hours without exercise, and neutral room temperature
whats listed on the label?
calories is the food form of energy and its the physiological fuel value for carbs, protein, and fat
plants is where we get most of our
carbohydrates in our diet take water up and take in CO2
first type of fiber water insoluble
cellulose heme-cellulose wheat, vegetables holds water and bulks up the intestine, speeds waste passage

fasting
decreases BMR approx 10-20% within 48 hours
what is his energy intake calculation

primary focus for carbs is
energy
basic functions of carbohydrates 3 types
energy crucial for brain and muscles strucutre regulate
TEF = thermic effect of food
energy needed for digestion of food and assimilation of food approx 50-200 5-10% of calorie intake
The Thermic Effect of Food (TEF) is the
energy needed to digest and assimilate food. The TEF is the smallest component of our energy need, since its value usually falls between 50-200 kcal.
Lactose intolerance is due to the low activity/lack of the
enzyme lactase which is used to digest the milk sugar lactose.
Indigestible energy losses from protein appear in the stool, while indigestible energy losses from carbohydrates appear in the urine.

Both high fructose corn syrup and table sugar are made up of glucose and fructose units. The difference is that in high fructose corn syrup,
glucose and fructose exist as monosaccharides, while in table sugar the glucose and fructose are bonded together to make the disaccharide, sucrose.
3 fav monosaccharides
glucose(blood, starch, 1/2 table sugar) fructose (fruit sugar) galactose (1/2 milk sugar this makes up half of lactose)
The amount of energy needed to support the cost of building new tissue and the material that makes up tissue (i.e. muscle and bone) is the cost of __________ and is taken into consideration for ___________.
growth children only "Growth" is the energy needed to build new tissues, as well as to build the material that makes up these tissues, such as muscle and bone. Growth is taken into account when determining a child's energy requirement.
second type of fiber: water soluble
gums pectins fruits oats beans
diet sodas do not
have any carbohydrates
Check all that apply. Body functions that contribute to the BMR include:
heart beating lungs breathing in and out liver doing its maintenance duties
calorie
heat or energy measure in food kilocalorie kcal
TEF thermic effect of food
heat/energy needed to digest and assimilate food
BMR = basal metabolic rate
heat/energy needed to keep basic body functions going such as heart and lung function
health benefits of water soluble fiber
helps lower blood cholesterol helps lower heat diseasee risk and type 2 diabteesl cardiovascular disease helps reduce appetite (potential weight control) slows digestion, leading to greater feelings of fullness maintains better blood glucose levels
health benefits of water insoluble fiber
helps relieve constipation helps lower risk of colon cancer(kicking out carcinogens) helps lower incidcen of large intestinal problems such as herrhoids and diverticulitis
fiber % DV
if can is 8 grams 8/25 grams x 100 = 32 % DV for one cup
lactose intlerance
inability to digest lactose lackign aenzyme lactase
exercise
increases BMR (variable effect)
fiber
indigestible many health benefits
milk
lactose; dissacharide
Water-insoluble fiber holds water, which causes the stool to bulk up in the intestinal tract,
leading to a faster passage of waste.
the physiological fuel value is going to be
less than what you get from a bomb calorimeter

Yogurt is a simple carbohydrate
made of lactose, which is a disaccharide.
Males have a greater BMR per unit of body weight because
males typically have more lean muscle tissue, while females typically have more body fat. Lean muscle tissue requires more energy to maintain than body fat does. The equation used for males is 1.0 kcal/kg body weight per hour, while the equation is 0.9 kcal/kg body weight per hour for females.
fruit is
monosaccharide simple sugars
The basic unit of all carbohydrate is a
monosaccharide, which is a single 6-carbon ring structure.
Glucose is the monosaccharide that is
most commonly found in food and inside of you.
what do you do?
multiply the BMR with .%
how do you determine how many calories you have?
need macronutrient info: protein,carb, protein grams and then apply physiological fuel value
The Basal Metabolic Rate (BMR) is the amount of energy/heat/calories
needed to keep basic body functions going. The BMR is measured in a person at rest and without food or exercise for 24 hours. The BMR is typically the largest component of our daily energy needs (~1,000-2,000 kcal/d).

a bomb calorimeter is used to calculate the number of calories in food the total or max number of calories in food represents the
potential energy
A calorie is the heat needed to
raise 1 liter (about 4 cups) of water 1 degree Celsius. When we eat food, we break the chemical bonds in the macronutrients (protein, carbohydrate, and fat), release energy in the form of heat, and release carbon as CO2. The amount of energy released from the carbon-containing food is equivalent to the energy released when an animal eats this same food.

"Activity" takes into account the energy needed to do any body movements above rest (i.e. sitting, standing, walking, etc.). The activity component is usually equal to or less than your BMR.

calculate BMR
women: 0.9kcal x body weight (kg) x 24hrs = kcal/day men: 1.0 kcal / (kg x hr) x body weight (kg) x 24hrs = kcal/day
physiological fuel value for protein
you loose more indigestible loss in stool so its 4kcal/g
To calculate her TEF, you would do the following:
0.05 x (1,642 kcal/d + 821 kcal/d) = 123 kcal/d. 107 kcal/d is the TEF for a 76 kg male with a light activity level.

Fat calories = 90 kcal Carbohydrate calories = 144 kcal Protein calories = 48 kcal Total calories = 282 kcal Using the information above, calculate the percent of calories coming from fat, protein, and carbohydrates in the hummus from the previous question. You will type in the correct answer from the options given in parentheses. % Fat Calories Divide the number of fat calories, kcal (90, 144, 48, 282) by the total calories (90, 144, 48, 282) kcal and multiply it by 100 to get our percentage of % fat calories. (32, 51, 17) % Carbohydrate Calories Divide the number of carbohydrate calories kcal (90, 144, 48, 282) by the total calories kcal (90, 144, 48, 282) and multiply it by 100 to get our percentage of % carbohydrate calories. (32, 51, 17) % Protein Calories Divide the number of protein calories kcal (90, 144, 48, 282) by the total calories kcal (90, 144, 48, 282) and multiply it by 100 to get our percentage of % protein calories. (32, 51, 17)
Fiber is made up of monosaccharides units that provide potential energy, that's only available to animals that can digest fiber.
Humans have the enzymes to digest the polysaccharide starch, but not fiber. Since humans don't make the enzyme to digest fiber, the energy in fiber is not physiologically available to us.
