If you want to lose 1 pound of "fat," which is 20% water, how many kilocalories do you need to expend?
i don't know where to start :(
Please Help!!!
To calculate the number of kilocalories you need to expend in order to lose 1 pound of fat that is 20% water, you can follow these steps:
Step 1: Determine the total weight of the 1 pound of fat. Since the fat is 20% water, this means that the fat itself accounts for 80% of the total weight. We can calculate this as follows:
Fat weight = Total weight * (1 - water percentage)
= 1 pound * (1 - 20%)
= 1 pound * 0.8
= 0.8 pounds
Step 2: Find out the number of kilocalories required to burn 1 pound of fat. It is commonly accepted that to lose 1 pound of body weight, you need to create a calorie deficit of 3500 kilocalories. Therefore, the number of kilocalories required to burn 1 pound of fat is:
Calories required = Calories per pound * Fat weight
= 3500 kilocalories/pound * 0.8 pounds
= 2800 kilocalories
So, to lose 1 pound of fat that is 20% water, you need to expend approximately 2800 kilocalories.
Please note that individual metabolic rates and factors like exercise level, body composition, and overall health can affect the actual number of kilocalories required for weight loss. It is advisable to consult a healthcare professional or a registered dietitian for personalized guidance.
To determine the number of kilocalories you need to expend in order to lose 1 pound of fat, which is 20% water, we can follow a step-by-step process:
1. Convert the weight of 1 pound of fat to kilograms. Since there are approximately 0.4536 kilograms in 1 pound, we can calculate: 1 pound * 0.4536 kilograms/pound = 0.4536 kilograms.
2. Determine the weight of water within the fat. Since the fat is 20% water, multiply the weight of fat by 20% (or 0.20) to get the weight of water: 0.4536 kilograms * 0.20 = 0.09072 kilograms of water.
3. Calculate the total weight of the fat and water that needs to be lost. We add the weight of the fat and water together: 0.4536 kilograms + 0.09072 kilograms = 0.54432 kilograms.
4. Convert the weight in kilograms to calories. Since there are approximately 7700 kilocalories in 1 kilogram of body weight, we can calculate: 0.54432 kilograms * 7700 kilocalories/kilogram ≈ 4193.84 kilocalories.
So, approximately 4193.84 kilocalories need to be expended in order to lose 1 pound of fat that is 20% water.
One pound = 454 grams. Subtract 20% fat to give 454-20%of 454 = about 363 grams.
I understand that fat calories = about 9 kcal/g therefore,
363 grams x 9 kcal/g = ?? kcal. This is approximate and you need to go through the steps a little more accurately. Also, the 9 kcal/g is my memory; you should confirm that number and use a different number if appropriate.
