Fat loss is not measured by weight alone. If you’re working out, you might be adding weight while losing fat. Your scale can’t tell you that, though. But, the Diet Belt can.

Wear the diet belt  it to track the inches you lose through dieting or the inches you add through breaking that diet. For better or for worse this belt will tell you how your circumference is changing. Unlike a significant other or friend who might wish to spare your feelings, the Diet Belt is as honest as it gets. And the nylon won’t stretch like leather, so you won’t need to worry about your measurements becoming inaccurate over time. (and if you don’t want to broadcast your width to the world, you can flip it inside out so your measurements are private!)

Maybe you don’t care about your waistline. Maybe you just need to measure stuff and don’t want a folded-up Ikea measuring tape in your wallet all the time. The Diet Belt has you covered.

Step 1: Tools + materials

Picture of tools + materials

  • scissors
  • sewing machine
  • clear thread
  • rotary tool /w metal cutting bit
  • solid-face trim-style belt buckle
  • fabric measuring table
  • fabric for belt
  • straight edge + marker
This project involves cutting metal, wear appropriate safety gear and work within your experience.

Step 2: Sew and trim

I didn't like the fabric my belt came with, so I used a wide, flat strip of black nylon instead. The fabric measuring tape was sewn onto my belt fabric using a transparent thread. I sewed my measuring tape with plenty of extra belt fabric on either end, then trimmed the 'zero' end with a straight cut and the end of the measuring tape with a tapered cut, just like a real belt.

really good idea
It might look nicer if you flipped it inside out.

I made mine in one evening. It cost me ~$10.50 (USD). I tried making mine with a round window rather than a square but I believe a square hole would have been much less problematic for the Dremel cutting wheel I used, But I like the round look all the same. Please let me know what you think.

Great belt! Now you can keep track of your waistline changes. My rectangular opening was a function of the tools I was using, but I like your rounded window more.

I had an idea for making myself instantly slimmer years ago, when tape measure belts first came out - I'd make every "inch" 1.25 inches long, hey pesto, slim waist! never did it though

Actually, for professional studies of waist size they use a tape that has some elastic in one end, and than the tape is pulled until the elastic portion is one inch.

I was thinking that it might be possible to put a scale on both sides of zero so that when you put the belt on, it would not announce the total size, only inches gained or lost..

Very creative. Would it be cheating to "alter" the numbers? lol :)
You are clever!!
Maybe I need to write the instructable for altering the numbers in this ible. :)
lol... I like the way you think! ;-D
Thanks. You called me a Wizard recently, why wouldn't you like the way I think? ;)
If only I had done this at the beginning of my pregnancy to see how big I have gotten!

Brilliant idea! It's great to have a measuring tape on hand whenever you need one.

I wonder if I could modify the buckle to also work as a bottle opener... 
Would that just undo all the hard work of maintaining the diet?
Motivating! Thanks for posting :0)

Ha, very nice!
You should measure the tension in the belt as well!
