Using the calipers accurately can be tough to do. I tried it and I didn’t have much luck. What I ended up doing was taking measurements of my stomach every two weeks. This is where most men carry fat. It seemed for me while I was cutting down if I lost 1/4-1/2" in two weeks I was doing decent. Just keep a log somewhere with your weight and it is a good place to start. You can try to keep track of your caliper measurements as well if you want. I did and it seemed like I got a little better with using them.
