In the later part of her first year of college, Lisa is doing well, losing some of the weight she put on at the beginning of the school year. Her highest weight was 160 pounds and she now weighs 152 pounds. How many kilograms does Lisa now weigh?
69 kilograms
(A kilogram (kg) is equivalent to 2.2 pounds. If she weighs 152 pounds, divide this by 2.2 to find out that she weighs 69 kilograms.)
Lisa is trying to choose more low-fat foods in order to reduce her risk for cardiovascular disease. One low-fat cookie that she sees advertised in the grocery store has 22 grams of carbohydrate, 2 grams of protein, and 1 gram of fat per cookie. How many kilocalories are in one of these low-fat cookies?
105 kcal per cookie
(Carbohydrate has 4 kcal/g, protein has 4 kcal/g, and fat has 9 kcal/g. For this cookie:
22 g carbohydrate × 4 kcal/g = 88 kcal from carbohydrate 2 g of protein × 4 kcal/g = 8 kcal from protein 1 g of fat × 9 kcal/g = 9 kcal from fat Total kcal per cookie = 105 kcal per cookie)
Bob was recently diagnosed with type 2 diabetes. His dietitian recommended that Bob follow a 1,800-kcal meal plan for weight loss. She said he should also follow the Food and Nutrition Board (FNB) recommendation of getting 45% to 65% of these calories from carbohydrates. This is equivalent to ______ grams of carbohydrates per day.

Since beginning college, Lisa has put on about thirteen pounds. She is learning in her health science class that excess calories contribute to weight gain. One recommendation her instructor made for weight loss is to choose foods that have a low percentage of total calories coming from fat. If a 1/2-cup serving of her favorite ice cream has 310 kcal and 20 grams of fat, what percentage of total calories in the ice cream come from fat?
58% of calories in this food are from fat.

Unscientific info based on personal accounts, can lead to future research
What is a meta-analysis in an experiment?

What is a randomized controlled trial?
Experiment with researchers manipulating something and comparing the group given the treatment to the group given no treatment or another intervention.
What is a cohort study?
Groups of people followed overtime to monitor the development of a disease and exposure to risk factors.
What is a case-control study?
- Subjects with a disease/condition compared to similar subjects without a disease/condition
- Helpful for studying rare diseases.
What is a cross-sectional study (observational)?
- An observational study (researchers not manipulating) that looks at data from a group at a certain point in time
- Often uses questionnaires or surveys
- Can include calculations
- Determines prevalence (#of people at a time)
