Question

Last night, Hannah’s mom called and said she’d be late getting home from work, so Hannah made dinner. She was tired after her classes and had a lot of homework to get to; so, she kept it simple. Hannah made them each a cheeseburger-no bun!-served with frozen French fries and some carrot sticks with guacamole on the side. They both had a cola, too. Later that night, though, when Hannah was studying, she got a snack attack and raided a package of sugar-free cookies. She ate maybe three or four, but she didn’t think it was a big deal because they’re sugar-free. Then when Hannah checked the package label this morning, she found out that each cookie has 90 calories! It bummed her out-until those cookies, she’d been doing pretty well on her new low-carb diet!

1. Hannah takes public transportation to the community college she attends, and does not engage in regular physical activity. Without analyzing the precise grams of carbohydrate or number of calories in Hannah’s meal, would you agree that before the cookies she’d been “doing pretty well” on her low-carb diet?   

2. In other words, would you describe her meal as low carb?   

3. Would you characterize her meal as low in energy?

4. About how many grams of dietary fiber do you think were in the meal? (Use the Food Composition Table from the companion website to assist you)

Answer 1

1 . No ,

2.Her meal we can consider it as a low carb.because Low-carbohydrate diets restrict carbohydrate consumption relative to the average diet. Foods high in carbohydrates are limited, and replaced with foods containing a higher percentage of fat and protein, as well as low carbohydrate foods. anything under 100–150 grams per day is generally considered low-carb. This amount is definitely a lot less than the standard Western diet.

3.no because Most cells prefer to use blood sugar, which comes from carbohydrates, as the body’s main source of energy.Her low carb diet that causes the body to release ketones into the bloodstream. Most cells prefer to use blood sugar, which comes from carbohydrates, as the body’s main source of energy. In the absence of circulating blood sugar from food, we start breaking down stored fat into molecules called ketone bodies (the process is called ketosis). Once you reach ketosis, most cells will use ketone bodies to generate energy until we start eating carbohydrates again.
