Does anybody in this forum use a food scale..are they worth it? My husband likes to count calories but most of the time he guesses and I have a strong feeling he is miscalculating. He is a strong long distance runner but he is having the hardest time loosing weight and I suspect its his diet plus I don't think he really pushes himself. He has been running for a very long time that its just comes easy to him. I was thinking I would give him a food scale for fathers day or maybe a heart rate monitor that will let him know when he is not working out hard enough.
