thestik   I'm a little concerned that the total Calorie count given for a weight of 118 pounds is only 1180 for losing fat. That's below the ACSM requirement of 1200 Calories per day for women. The 1416 Calories for losing fat and gaining muscle is a little bit easier to stomach but still a bit unnerving. I'd like to know exactly how the total Calories are determined with this calculator because all those figures seem a little on the low side, and I'm in the moderately active category. - 5/14/2014 12:53:44 AM

BonBon   I was lucky enough to gain 6 calories when I switched from US to Metric. I understand the US measure in volume and Canada measures by weight so that might account for more calories. - 1/22/2011 12:16:25 PM

Brandie   has anyone noticed that if you set it up and then switch it to metric it adds like 2 calories...? or is that just a glitch on my end? - 11/16/2010 2:30:46 PM

AmyC   Beans are an excellent source or protein. Soy is a bean also but you can get Soy milk flavored if you are not a milk fan. If you like Cheese but don't like the fat try the low fat cheese, the 2% cheese is pretty good. - 9/22/2009 6:42:46 AM

Natalie Z.   I am a vegetarian, and I don't eat fish. Where can I get protein from? I don't particularly like eggs either so cheese is about it, however it has a high fat content. - 5/1/2009 6:11:55 AM

Dionne P.   I agree. Age, height, gender, and ehtnic backround should be cosidered in the calculations. Also whether or not you have a blood sugar problem or other health issues, { like glands }, that would make it more difficult to loose or gain. - 9/11/2008 12:29:25 PM

Jeff G   Good tool for rough estimates of caloric need and % distribution. Would be nice if it were to take into consideration age and gender as well - 9/4/2008 10:52:30 AM
