There are a variety of options for approaching weight loss, but each has pros and cons. While success will vary for different individuals, there are several evidence-based strategies that are more likely to contribute to success. From the list below, choose all the correct statements for healthful weight loss. -A healthful weight loss strategy involves losing weight as quickly as possible. -Weight loss goals should be specific, reasonable, and measurable to increase the likelihood of success. -People who exercise regularly are more likely to lose weight and maintain weight loss. -If reduced-Calorie foods are chosen, portion size is not important. -Severely restricting fat or carbohydrates may result in weight loss, but these diets may provide inadequate nutrients and can have related health risks.
-Weight loss goals should be specific, reasonable, and measurable to increase the likelihood of success. -People who exercise regularly are more likely to lose weight and maintain weight loss. -Severely restricting fat or carbohydrates may result in weight loss, but these diets may provide inadequate nutrients and can have related health risks.
There are a variety of tools and measurements available to assess body composition and health risks, each with some limitations. Some examples are BMI, fat patterning, waist circumference, and waist-to-hip ratio. Choose the correct statement about body composition evaluation methods. -Fat stored around the waist can lead to unhealthful changes in blood cholesterol, insulin, glucose levels, and blood pressure. -For females, the waist-to-hip ratio should be below 0.8, and waist circumference should be below 40 in. -A healthy BMI falls in the range of 18.5 to 30. -Pear-shaped fat patterning significantly increases a person's risk for chronic diseases.
Fat stored around the waist can lead to unhealthful changes in blood cholesterol, insulin, glucose levels, and blood pressure.

False
In addition to biological influences on body weight, cultural, economic, and social factors play a role as well. Some of these factors, such as the pressure to overindulge on holidays, are nearly ubiquitous, whereas others, such as living in a community in which it is unsafe to walk or exercise, affect certain people more than others. Choose the statement about cultural, economic, and social influences on body weight that is not correct. -Living in an unsafe community is an example of a social factor that can lead to being less physically activity. -Larger body size is culturally acceptable among certain ethnic groups. -Media images of male and female models may encourage young adults to follow dangerous diet and exercise plans. -People with lower incomes have lower rates of obesity than people with higher incomes.

People whose bodies use relatively more fat for energy are more resistant to weight gain than people whose bodies use relatively more carbohydrate.
True
The classic energy balance equation states that when energy intake equals energy expenditure, energy balance exists and weight remains stable. If energy intake exceeds expenditure by about 3500 kcal over a period of time, an individual should gain 1 lb of fat; and if energy intake falls short of expenditure by 3500 kcal, he or she should lose 1 lb. Choose the statement that explains why the energy balance equation does not always accurately predict the amount of weight gained or lost when a person consumes more or less energy than required. -When energy intake is greater than energy expenditure, a spontaneous increase in energy output may occur. -When energy intake is greater than energy expenditure, all of the excess energy is stored as fat. -When energy intake is less than energy expenditure, the body becomes less metabolically efficient. -When two individuals of similar size eat the same number of Calories in excess of their needs, they will always gain the same amount of weight.
When energy intake is greater than energy expenditure, a spontaneous increase in energy output may occur.
