CHANTAL please assist with the amount of calories i need to consume - 3/11/2014 6:55:05 AM

krinermom6 I found this a great starting point. I agree with Girl, but there isn't a system out there that takes all of that into account yet. Maybe another question could take into account our fat percentage. Anyone who is into fitness can get that measured, and any YMCA will do it for anyone! That would help. Scientists... get on it! LOL Very helpful to start out. - 1/10/2010 7:37:22 PM

Girl Dude they don't take into consideration muscle weight vs. fat weight. my body weight seems like alot, but i'm not fat. i'm very active, and just have alot of muscle. i feel like they need to ask more questions to find an accurate calorie counter. - 10/25/2008 9:14:05 AM

Russ The calories in this calculator are the same calories normally associated with eating food and exercising. When you are talking scientific measurements, then you are referring to 1000 calories (1 kcal) = 1 Calorie. - 10/7/2008 6:04:13 AM

Zamri In the above calculator, does 1000 calories = 1 kcal? - 10/6/2008 12:32:39 AM
