indicates being overweight, but Janet has a more at-risk waist to hip ratio as her
value is greater than 0.8.
Bioelectrical impedance estimates a person's body fat - ANSWER-By
measuring the degree of resistance to an electrical flow

Ryan was comparing two nutrition labels for snacks at the grocery store. Snack
#1 had 130 calories per serving and 4 grams of total fat, while Snack #2 had 145
calories and 2 grams of fat. Which snack would be the better choice for Ryan's
weight loss goals and why? - ANSWER-Snack #1 because when looking at
labels and comparing products, remember that calories are important, regardless
of whether they come from fat, carbohydrates, or protein.
Along with nutrition label reading and keeping a food journal, what are at least
2 more recommended behaviors for controlling calories? (Note: Behavior
modification and behavior-modification strategies are not to be listed as a
recommendation.) - ANSWER-Measuring portion sizes limiting high fat
foods
limiting empty calorie foods/foods high in sugar
What are the two main classes of minerals and what determines which class a
mineral is assigned? - ANSWER-Major minerals (minerals which are needed in
amounts greater than 100 mg/day) and Trace minerals (minerals which are
needed in amounts less than 100 mg/day)
Choose two minerals, one from each major class. Describe the symptoms of a
deficiency in the mineral and suggest a way in which the deficiency may be
avoided. - ANSWER-Major: Magnesium. Deficiency symptoms include
irregular heartbeats, weakness, muscle pain, and seizures. Milk and meat are
high in magnesium, and consuming them can help prevent magnesium
deficiency.
, Trace: Iodine. Symptoms include low white blood cell count, poor growth, bone
loss, and anemia. Deficiency is not common as table salt in North America is
fortified with it. Elsewhere in the world,
Why can foods advertised as "low-fat" and "fat-free" really not be advantageous
for weight loss? - ANSWER-The calorie difference between low-fat and its
regular counterpart can be marginal as extra sugar (or salt) can be used to
improve the taste. Additionally, the lack of fat or simply the knowledge that the
product is lower in calories, may lead you to actually eat more of a low-fat
product. The end result is often the consumption of more calories than if you
had just ingested the regular product initially.
Zoe enjoys going to the coffee shop and ordering coffee drinks with flavored
syrups and treating herself to frozen coffee drinks with chocolate and whipped
cream. Why are these habits detrimental to weight loss goals and/or
maintenance? - ANSWER-Drinks can have high calories but not lead to a

their calorie intake or allowance for weight loss and maintenance.
