Gaining

You actually can use MyFitnessPal to do this. I'm doing it. MFP only calculates 1 lb/wk, but as august said, use a tdee calculator, then set your MFP calorie goals to the amount that will fatten you up. Then you start logging your meals. Without consistent strength training excess calories will go to fat.

I've thought of something like this, but went further.... Mine would be a small device that would be secured to the feedee, which would have all the features that a feeder would want to allow for remote monitoring.

Including:

real time vitals monitoring
activity monitoring/gps reporting
secure reporting via internet

Perfect for the long distance feeder and his/her feedee.

On sale now. *just kidding about this last part*
