I'm looking for something I can put on my Iphone where I can log my daily food intake and track my weight.

Have you found any good apps for that? There are so many. I've been looking through them all but I thought I'd see if you guys recommend any.

I use livestrong as well, I love it!!!

I use myfitnesspal. I have used sparkpeople, calorie count, and a couple of others and myfitnesspal seems to me the most accurate. Plus it has a lot of the food i use in the system. It also has a nifty bar code scanner that i can scan and add to my journal. You can access it online or on your phone. Very user friendly. Plus it keeps track of my weight and automatically updates the ticker below. I can print out reports and charts to take to my DR as well since mine is strict regarding "no diary = no fill". He wont fill me unless he knows i am following the nutritional and dietary requirements.

It's already been suggested a few times but I LOVE myfitnesspal. It's excellent

I love myfitnesspal too. Very easy and has every kind of food imaginable.

Online I use fatsecret.com which has an ap for my DROID phone so I would think there is one for the iPhone. My phone will synch to the online account and viceversa.

The coolest part about the Ap is that is has many national restaurant nutritional info in its data base and every food I have every looked up! It also has a bar code scanner so you dont even have to type!!
