Q. I want to lose weight, but when I get too hungry, I overeat. How can I tell when to ignore the urge versus when it's time to eat before I'm too hungry?
A. It's not always easy to know the best time to eat, especially if you've spent years dieting with a mindset of trying to ignore your body's hunger signals. The good news is that the skill of knowing when you are truly hungry becomes easier the more you practice it, and this will not only help you lose weight but can play a key role in helping you maintain a healthy weight.

Begin by training yourself to recognize degrees of hunger by rating it on a one-to-ten scale before and after you eat. (Ten equals stuffed, one equals feeling so hungry you'd gulp down anything, and five equals "neutral.") With practice, you'll learn to recognize signals of hunger and know when to eat something before you get to the point of out-of-control overeating. For some people, it's stomach rumbling; for others, it's decreased ability to focus attention.
You can also practice recognizing non-hunger urges to eat. For example, you might notice that you're sensitive to cues like seeing others eat or smelling pleasant aromas from a bakery. You may also learn that you use eating as an "excuse" when you need a break or as a way to cope when upset or tired.
Behavioral therapists often note that this desire to eat when not hungry tends to come in a wave. If you aren't hungry, the urge will usually pass if you can distract yourself with something else for a little while. The problem is that most of us don't realize that and give in to the urge too soon.
The bottom line is learning to tune in and trust your body signals. Keeping some form of journal can be very helpful to this process. If you find losing weight challenging, a few sessions with a registered dietitian (RD or RDN) trained in behavior modification can help you learn to read your body signals and understand how eating choices can set you up for more long-lasting hunger satisfaction. If you don't know how to find one in your area, go to the website of the Academy of Nutrition and Dietetics (eatright.org) and enter your location information under "Find a Registered Dietitian."
Q. How much nutrition do I lose by using frozen spinach instead of fresh?
A. Spinach is a powerhouse food containing vitamins and minerals and is a rich source of phytochemicals such as carotenoids and flavonoids.
In general, the nutrients and other protective compounds in spinach are similar whether you use fresh and frozen. But compared to the frozen form, freshly harvested spinach provides more folate, a B vitamin that some studies have found may prevent heart disease according to the American Heart Association. However, a study at Pennsylvania State University shows that when fresh spinach sits in a truck for transportation over long distances, or sits in your refrigerator for a week, folate content drops so much that frozen spinach becomes the better source. Freezing spinach does not seem to mean any loss in beta-carotene content.
Frozen spinach is terrific to keep on hand for an easy nutrient boost in soups and sauces. For other uses, cook spinach (fresh or frozen) by steaming, microwaving, stir-frying or sautéing to retain folate and vitamin C. Boiling spinach in a pot of water can cut these vitamins' content in half.
When using frozen spinach, you can reduce vitamin C losses by cooking it directly from the freezer without thawing it first. However, to add frozen spinach to a casserole or pasta dish such as lasagna, your dish may turn out best if you do first thaw it (using the microwave makes it quick and easy), then place in a sieve or colander and use a large spoon to squeeze out the excess water. By squeezing this water in a bowl, you can refrigerate it and save to add to soup or pasta sauce, thus avoiding loss of vitamin C or other water-soluble nutrients.
