If you weigh more do you need more calories??


Question: My friend weighs more than me and she is on a 3,000 calorie diet, and I am on a 2,000, and she seems to be loosing weight faster than me????
Answers: A larger body mass will generally require a greater caloric intake to maintain BMR (Basal Metabolic Rate) and AMR (Active Metabolic Rate) levels. But it really depends on how active your friend is. Perhaps he/she is quite active throughout the day and this places him/her in a substantial calorie deficit which allow he/she to lose a good deal of weight within a short time period. Here's a calculator to help you assess BMR and AMR.

It is dependant on your body mass index (a formulated # based on height and wieght) as well as your activity level.
Is she getting more exercise? Could also depend on the KIND of calories she is ingesting. If you look on the boxes of foods (or check a calorie counting book or website), certain foods have FAT calories.

Transfats are also bad bad bad. Might check for those as well.

I'd need more information about previous weight and activity, and what exactly the two of you are eating to tell more.

Hope that helps!
I am doing weight watchers right now and you are allowed more calories the more you weigh. My husband is allowed many more calories than I am because he outweighs me by about 60 pounds.
That depends on some different factors. Simple answer is yes. On average people who weigh more need more calories. If you dont eat enough your metabolism slows and weight loss slows. If you eat too much you store fat. Try eating more. You may just lose weight faster. You will have to experiment a little as everyone is different.
It all comes down to body composition. A person with more muscle mass will have a higher metabolism rate, and thus require more calories to sustain his or her weight than a person who has a large percentage of bodyfat since muscle has a higher metabolic rate. The key to diet is to expend more calories than what you take in (to an extent ... not anything less than 10%).

Another factor that might enter the equation is how much your friend is exercising compared to you or their overall activity level.
