Some nutritionists are claiming that the secret to long life is to be slightly underweight as an adult. If a person’s weight is related partly to diet, partly to activity level, and partly to genetics, what underlying factors could be at work to generate statistics that support this claim?
Nutrition plays an essential role in supporting fitness and exercise. If you increase your level of physical activity, your need for nutrients and calories will also increase. In addition, the foods you eat before and after you exercise will have an impact on your performance during physical activity and on your recovery afterward.
Perform some library research, and in a 2–3-page paper written in APA format using proper spelling/grammar, address the following:
Describe the importance of pre- and post-exercise nutrition choices. Provide examples of foods that are appropriate selections for each category. be specific: I do not want to see protein and fruit, instead, you could write protein shake with 1 g sugar and one medium banana. Carry this thought thru out your paper.
Explain how foods and nutrients (including fluids and electrolytes) help improve a person's performance during physical activity and their recovery afterward. be specific: I do not want to see protein and fruit,…
Choose which step of the scientific method is represented by this statement:
Will people who eat fast food, daily, develop symptoms of poor health related to obesity?

- Vegetarian diets are associated with a lower risk of obesity and diabetes as well as other chronic conditions (Marsh, Zeuschner, & Saunders, 2012). Clearly a vegetarian diet can be a healthy one, but can a vegetarian diet lack nutrients? If so, which nutrients may be lacking? How could these nutrients be measured in the body to determine if someone is deficient in them? Are there vegetarian foods that provide these nutrients or would supplementation be necessary? Are there any interactions to be aware of with the supplements that a vegetarian may take?arrow_forwardAre the following statements true or false? A. Most of the energy stored in the human body is in the form of fat, followed by protein. The body has only limited capacity for storage of carbohydrate. B. It is estimated that one kg of fat gain requires 2500 kcal of energy surplus. A is true, B is true O A is false, B is true A is true, B is false O A is false, B is falsearrow_forwardLifestyle and genetics are each important components of health. Recent research provides evidence for which of the following statements?

- Joe would need to cut back on sweets and eating late at night. His carb intake is very high, so we recommend more fruits and vegetables low in calories and low in fats. What is the independent variable? What is the dependent variable?arrow_forwardA researcher wants to investigate whether a daily corn-based diet supplemented with powdered milk would increase the daily weight gain of growing calves. What is the Independent and Dependent variable of this experiment?arrow_forwardA researcher assessed body weight in a community using two methods. First, participants were asked, “Do you think you are overweight?” (Possible answers: ‘yes’ or ‘no’). All participants were then weighed and classified as ‘overweight’ or not. The assessment was however done separately by hypertensive status. Among 270 hypertensive participants, 108 were classified as overweight on the basis of being weighed. Of these 108, 54 reported themselves as overweight when questioned. Of the 162 participants not classified as overweight on the basis of being weighed 16 reported themselves as overweight when questioned. Among 745 non-hypertensive participants, 134 were classified as overweight on the basis of being weighed. Of these 134, 118 reported themselves as overweight when questioned. Of the 611 participants who were not classified as overweight on being weighed, 110 reported themselves as overweight on questioning. Separately for the groups: (1) People with hypertension (2) People…arrow_forward
- Give examples of Studies confirm a genetic influence on body weight?arrow_forwardObesity is a serious health problem for many Americans. Several popular diet plans advocate low-carbohydrate diets. Most low-carb dieters compensate by eating more protein and fat. What are the advantages and disadvantages of such a diet? Should the government regulate the claims of diet books? How should the claims be tested? Should diet proponents be required to obtain and publish data before making claims?arrow_forwardImagine that you are trying to assess the relative influence of a host of enviormental factors on the growth (body mass) of a certain fish species. Your observation will be made in several streams. The focus is on identifying what factors are important in explaining weight gain. Please tell me: a) How would you design the experiment to identify which enviormental factors are most important? b) How would you test your hypotheses? (what statistical analysis would you do?) Can you show me what the equation might look like?arrow_forward
- Caroline is a 39-year old high school English teacher who weighs 141 pounds and does not get a lot of exercise. Based on this information, each day Caroline should consume _____ grams of protein for each kilogram of body weight, meaning that she should consume approximately _____ grams of protein per day.

What is the controlled variable for this experiment?arrow_forwardhGH is an important part of fat metabolism, muscle development, and bone growth. Synthetic hGH can be used to treat children and adults suffering from hGH deficiency. More recently, competitive athletes have began taking hGH in an attempt to improve athletic performance. The use of hGH for athletics is banned by many major sporting organizations. A recent study of 44 athletes who took daily injections of hGH over 20 days showed that, on average, the athletes gained 4.2 lbs of muscle, but the gain in muscle did not translate to increased athletic performance.Evaluate each statement regarding the use of hGH by competitive athletes to determine whether the statement is an example of an ethical, economical, societal, or environmental issue. Athletes who play professional sports should be encouraged to take synthetic hormones to improve performance because their job is to win. Athletes who took hGH did not improve their sport performance but did improve their appearance and marketability.…arrow_forward
