I own this bathroom scale. I 10/10 would buy this scale again.

• Smart Weigh Digital Bathroom BMI Body Fat Weight Scale, Tempered Glass, 440 pounds, Black $29.99

For a food scale, this one is most popular in /r/loseit and has a great price on it right now...

• Ozeri Pronto Digital Multifunction Kitchen and Food Scale, Elegant Black $7.95

I got an awesome deal on this scale that measures body fat %, water, muscle mass and bone mass. It's a little more expensive than what I got it for on a lightening deal but still worth it.
