Two comments:
1. Don't forget to consider how accurate the spring = fat model is. You may need to independently confirm this, as you don't want to rig your experiment to get the results you need.
2. Animal fat. You get animal fat and measure the compression under a given force, if you're going to calibrate a set of springs to simulate fat compression. As you mention, Hooke's Law => your spring constant.
3. Bad Idea
Regardless, best of luck.
edit: Rethought #3...probably more trouble than you want to get into.
