When it comes to food scales, there’s low-scale and up-scale. The low-scale ($5 - $10) type postage or “diet” scales simply help you figure a food’s weight. That’s valuable information. For example, when you weigh meats, you not only zero in on the portion you should eat but you also 'see' what certain amounts of food look (and should) look like. This improves your guestimating (as I call it) skills both at home and when you eat out.
