How do u tell how much abdominal fat is left without a personal trainer

Well, I personally don't figure out how much belly fat is left because it's either there or it isn't. It may also be the last to go, so there's a chance that it won't change for a while. There are also people who don't have enough lean mass to have a flat stomach, so they would have to get to very low body weight to get close to losing the belly fat.

If you absolutely need to know how much fat you have you could try the visual method.

Look in the mirror?

get some calipers from e-bay.
they're probably less than $5..

Abdominal fat? Or body fat? Because the answer to that will depend on how you store your fat. Your male according to your profile (I was thrown by the username at first!) so there will be less variance with where fat is stored than on a female - I was about to launch into a massive spiel about whether you store fat on your lower half or tummy until I realised it wasn't applicable! Visual guides are the best best, try googling images of male body fat. There is a good male chart on the built lean website. I think how you look and how you feel are much better guides to body fat than anything else. Photos help if you feel you aren't seeing progress, try taking them every 4 weeks or so to compare.
