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
