How many calories do i need to eat to lose weight?

Answers

Worry less about the amount of calories and more about how. so consider options such as exercising and eating well balanced meals without bad ingredients. try to find organic foods (usually they will have less surgar) don't avoid carbs completely but limit intake. basically get into healthy eating and regularly exercising to help loose weight. don't focus on the numbers just make your body feel happy. :)

[tex]1.21\times 10^4[/tex] cal would be needed to heat 5.0 lbs of copper from 22 degrees C to 80.0 degrees C.

Explanation:

[tex]Q=m \times c \times \Delta T[/tex]

where

[tex]\Delta T[/tex] = Final T - Initial T

Q is the heat energy in calories

c is the specific heat capacity (for copper 0.092 cal/(g℃))  

m is the mass of water

plugging in the values

[tex]$Q=5.01 b s \times 0.092 \frac{c a l}{g^{\circ} \mathrm{c}} \times\left(80.0^{\circ} \mathrm{C}-22^{\circ} \mathrm{C}\right)$[/tex]

Please Note:

1 lb = 453.592grams  

So,  

5 lbs = 5 × 453.592g  = 2268 g

[tex]$\begin{aligned} Q &=2268 g \times 0.092 \frac{c a l}{g^{\circ} \mathrm{C}} \times 58^{\circ} \mathrm{C} \\\\ Q &=12102 \mathrm{cal} \end{aligned}$[/tex]

[tex]=1.21\times10^4[/tex] cal (Answer)

Answer&Explanation:.BMI is calculated by dividing the body weight with a square of the body height

Weight of Tonya is 68.6kg and height is 1.6meters (I converted feet to meters and pounds to kg), her BMI is above 25 which means she is overweight.

B.Using the rule of thumb total calories she needs are : her weight is 151 but normal weight for her will be 131 and the average is 141 which means estimated BMR is 141 lbs X 10 =1410 calories; since she leads a sedentary lifestyle the calories spent on activity is 141x20=282calories; recommended calories for her age is 1800. The total estimated calories requirement for her is 1692 since rule of thumb considers weight only.

C.Since 3,500 calories equals about 1 pound (0.45 kilogram) of fat, from this we can make an estimation that if you want to lose one pound , one needs to gradually lose or reduce their calories by 500 until they have burnt up to 3500 calories in total. For this reason if Tonya cuts her calories by 500 to 1000 they will lose 1 to 2 pounds in a week.

She will have to cut 500 calories per day in order to lose one pound per week

And 1000 calories if she want to shed 2pounds. This is a slow and sustainable weight loss which can be carried out throughout her life .
