Count calories the easy way. fatsecret even includes menu items from fast food and restaurant chains. Not sure about the accuracy of the exercise diary but it provides an estimate of daily calorie deficit. Biggest annoyance – nag messages on daily weigh in. The tool calculates estimated weekly weight loss. I can lose 3 lbs in one day when I cycle back into ketosis.

I started out with the calorie counter on this site and lost most of the weight while using this tool. Unfortunately, fitday lost my food diary when I took a break from dieting. Apparently, they delete data after an account is inactive for a period of time. Also lost all of the “custom” food items that I had entered.
