Problems when limiting sugar
Too many unhealthy choices Portion sizes are too big We drink too many of our calories People are uneducated about how to eat, what to eat and how much to eat.
Calories
A unit used to measure the amount of energy contained in foods Your body needs a certain amount of energy from: a) fat 9 calories per gram b) protein 4 calories per gram c) Carbohydrates 4 calories per gram Your body burns (metabolizes) these 3 nutrients to produce ENERGY which is measured in calories
Types of diets
Slimfast, Jenny Craig, Nutri-system, Atkins, South Beach, Beverly Hills Diet
Why FAD diets don't work

*Women should never go below ______ calories/day *Men should never go below _______ calories/day
*Women should never go below 1200 calories/day *Men should never go below 1500 calories/day
When you cut calories below 1200/1500
Your body goes into starvation mode and you have slowed metabolism, hunger pains, and fat cells do not release fat Once you start eating normally your body will make new fat cells before filling the old fat cells often resulting in becoming even more overweight than when you started.
Why is eating breakfast important?
With no food in your stomach, your body thinks it's starving, and your metabolism slows down Your brain needs nutrients to be alert, otherwise you'll feel tired and can't concentrate! Your body and brain need food in the morning for energy!!

6 essential nutrients
Fat Protein Carbohydrate Vitamins Minerals Water
Good fats
Unsaturated fats: Can help lower cholesterol levels and reduce your risk of heart disease. Examples- vegetable oils, omega-3s found in fatty fish (salmon), nuts
Bad fats
Saturated fats and trans fatty acids: Can raise cholesterol levels, clog arteries and increase the risk for heart disease Examples: animal products including dairy and eggs, vegetable fats like coconut & palm oil
Why do we need fat?
We need fat for energy + cushion + insulation
Good Fats are ....
Omegas + unsaturated
The bad fats are ....
Trans fat + saturated They're found in many dairy and animal products + tropical oils. It's "solid" at room temp.
What word do you look for when your looking for trans fats in food labels?
hydrogenated or partially hydrogenated (added to make foods solid)
Foods high in fat are....
-fast food -cured pork -butter -red meat + cheese -mayo / dressing -almost anything w/ "cream"
Cholesterol
measured via blood test
LDL
"lousy"-clogs arteries
HDL
"healthy" carries excess to liver
Why is high cholesterol bad?
High cholesterol is bad because it clogs arteries and leads to heart attacks, and strokes. (HDL is good cholesterol.) genetic
What is cholesterol found in?
meat, dairy, and eggs
Maximum grams of cholesterol someone should eat
300 mg your liver makes all the cholesterol you don't need to eat
Carbohydrates
4 cal. per gram There are simple and complex carbs.
Simple Carbs
table sugar bad for you (empty calories) make you gain weight, get diabetes and then blood sugar levels crash and you feel tired and crave more sugar Excess sugar is stored as fat!
Complex sugars
The good carbs are complex
Complex sugars example
whole wheat fruits veggies oats vitamins minerals fiber
Why should you choose whole wheat flour products?
Refined white flour is bleached and striped of vitamins and minerals
Enriched flour
most of the natural vitamins and minerals have been extracted. This is done in order to give bread a finer texture and increase shelf life. Enriched flour is flour with specific nutrients returned to it that have been lost while being prepared. These restored nutrients include iron and B vitamins (folic acid, riboflavin, niacin, and thiamine). Calcium may also be supplemented.
Carbs and Glucose
All carbs turn into glucose but the faster they enter the blood the worse it is and the faster they spike our blood glucose levels.
Foods that turn into glucose faster
processed foods, chopped, sliced, mashed, juiced
Foods that turn into glucose slower
fats, proteins, fiber, whole fruits and veggies
Type 1 diabetes
the pancreas, the organ that secretes insulin, is destroyed, that's why people with type 1 diabetes always need insulin, either injected or through an insulin pump.
Type 2 diabetes
more common primarily a complicated medical condition called 'insulin resistance.' In the early stages of type 2 diabetes, there's plenty of insulin around, it just doesn't work well. To treat type 2 diabetes, a healthy diet and plenty of exercise must be added to the person's lifestyle.
Warning signs of diabetes type 1
*can come on suddenly but usually during childhood-may be hereditary* Excessive thirst Frequent urination Extremely tired Rapid weight loss High amounts of sugar in blood and urine
Warning signs of diabetes type 2
*occur more gradually-most common and usually adult onset related to obesity* Blurred vision Tingling, numbness in legs, feet, or fingers Frequent skin infections, slow healing of cuts and bruises Drowsiness, Any of type 1 symptoms
Cure for diabetes
There is no cure at this point however.... Type 2 can be controlled with diet/nutrition, weight management and exercise. Those with diabetes have an increased risk-heart disease and stroke
Protein ____ cal. per gram
4

*True or False:* Extra protein from foods or use of protein supplements will help increase strength.
False Protein is made of small building units called amino acids. Extra amounts of amino acids will not build muscle strength. If more protein is provided to the body than needed, the extra will be used as energy, excreted, or stored as fat.

Too much protein can cause liver and kidney damage (kidney stones!) because the body can't store protein.

Muscular Strength
The amount of force a muscle can apply in a given contraction. Example: 1 RM (repetition max) for Squat
Muscular Endurance
The ability of the muscles to work over a period of time. Example: Sit up test Example: Swimming
Cardiovascular Endurance
The most important of the components of fitness The ability of you heart, blood vessels and lungs to deliver oxygen and nutrients to your cells (muscles). As your cardiorespiratory increases your resting heart rate decreases Example: Pacer test, 5km jog, lap swimming
Flexibility
The ability of the joints to move through their full range of motion. Example: Full squat Example: Sit and reach Being flexible significantly reduces the chance of experiencing occasional and chronic back pain. (Human Kinetics)
Body Composition
Ratio of lean body tissue (muscle and bone) to fat tissue. Excessive body fat is linked to many diseases including heart disease, diabetes and some forms of cancer. Can usually be controlled with a good diet/nutrition and exercise
