How many grams of nitrogen are contained in a 2,500 kcal diet that provides 15% of the energy as protein?

What would be the approximate weight gain of a person who consumes an excess of 500 kcal daily for one month?

Which of the following is an FDA approved over-the-counter medication for weight loss?
Answer
Leptin
Ephedrine
Benzocaine
Tetrahydrolipostatin

Ephedrine

To calculate the number of grams of nitrogen contained in a 2,500 kcal diet that provides 15% of the energy as protein, follow these steps:

Step 1: Calculate the total calories from protein
2,500 kcal x 0.15 = 375 kcal

Step 2: Convert the calories from protein to grams of protein
1 gram of protein = 4 kcal
375 kcal ÷ 4 kcal/gram = 93.75 grams of protein

Step 3: Convert grams of protein to grams of nitrogen
1 gram of protein contains approximately 16% nitrogen
93.75 grams of protein x 0.16 = 15 grams of nitrogen

Therefore, the 2,500 kcal diet provides approximately 15 grams of nitrogen.

To estimate the weight gain of a person who consumes an excess of 500 kcal daily for one month, follow these steps:

Step 1: Calculate the total excess calories consumed in one month
500 kcal/day x 30 days = 15,000 kcal

Step 2: Convert the excess calories to weight gain
1 pound of body weight is approximately equal to 3,500 kcal
15,000 kcal ÷ 3,500 kcal/pound = 4.29 pounds

Therefore, the approximate weight gain of a person who consumes an excess of 500 kcal daily for one month would be around 4.29 pounds.

Among the provided options, none of them is an FDA-approved over-the-counter medication for weight loss.

To calculate the grams of nitrogen contained in a diet that provides a certain percentage of energy from protein, we need to know the nitrogen content of protein and the total energy of the diet.

1. First, determine the nitrogen content of protein, which is approximately 16%. This means that 16% of the weight of protein comes from nitrogen.

2. Calculate the total energy provided by the diet. In this case, it is given as 2,500 kcal.

3. Determine the energy provided by protein. Since protein contributes 15% of the total energy, multiply 2,500 kcal by 0.15 to get 375 kcal.

4. Convert the energy from protein to grams of protein by dividing by the conversion factor of 4 kcal/g (the approximate energy content of protein). So, 375 kcal / 4 kcal/g = 93.75 g of protein.

5. Calculate the grams of nitrogen from protein by multiplying the grams of protein by the nitrogen content. In this case, 93.75 g protein * 0.16 (nitrogen in protein) = 15 g of nitrogen.

Therefore, the diet contains approximately 15 grams of nitrogen.

To determine the approximate weight gain of a person consuming an excess of 500 kcal daily for one month, we need to consider that 1 pound of body weight is approximately equal to 3,500 kcal.

1. First, calculate the total excess calories consumed over the month. Multiply the daily excess calories (500 kcal) by the number of days in a month.

500 kcal/day * 30 days = 15,000 kcal

2. Next, determine the approximate weight gain by dividing the total excess calories by the number of calories needed to gain 1 pound.

15,000 kcal / 3,500 kcal/pound = approximately 4.29 pounds.

Therefore, the approximate weight gain of a person consuming an excess of 500 kcal daily for one month would be around 4.29 pounds.

Regarding the FDA-approved over-the-counter medication for weight loss, among the options provided, none of them are FDA-approved medications for weight loss. Leptin, Ephedrine, Benzocaine, and Tetrahydrolipostatin are not approved by the FDA for this purpose. It's important to consult with a healthcare professional before considering any over-the-counter medication or weight loss product.
