Recipe Calorie Calculator Faulty???

Hi Everyone,

I've been entering a lot of recipes into the recipe calories calculator so that I can try and use recipes I like and either tweak them to be lighter or find lighter recipes online.

I usually use a lot of Cooking Light recipes as well as some recipes from cookbooks that do not reveal the nutritional information (Gwyneth Paltrow It's All Good, Oh She Glows, etc.). What's been freaking me out is that when I import a recipe from Cooking Light that already has the calorie count given using the URL or if I simply copy and paste the ingredients and ask the recipe calculator to match the ingredients, the difference in MFP's Recipe Calculator and Cooking Light's is ENORMOUS!

I just tried to add a light Pumpkin Pie recipe, for example, and Cooking Light has a slice at 238 calories and MFP has a slice at 489 calories!!! I've double checked the ingredients over and over and it's still putting the calorie count so high.

Has anyone else noticed this? Should I trust the Cooking Light over the MFP? Only, then I'm worried about the other recipes I've been using where I've manually entered. What if MFP is either grossly over estimating or under estimating the calorie count?

Any advice?
