What is a healthy dinner?

The old fashioned Blue Plate Special of "a meat and two veg" isn't too far from what makes sense for a healthy dinner. We know that combining protein with carbs helps you to feel satisfied for longer after a meal. However, many people don't know what to actually put on their plate.

Contributing to the problem is that serving sizes have become so large in many restaurants. This has carried over into dinner tables at home and portions at home have also gotten larger. So when you're considering dinner ideas, think in terms of right-sizing your meal.

Begin with the main course - the fish, lean meat, shellfish, chicken, turkey, lamb, etc. that you will have. The rule of thumb for a single serving for an adult is 4 ounces by weight. When you are reading recipes, keep this in mind, because many call for single serving sizes of double or even triple this amount. With a 4 ounce serving coming in at around 150 to 200 calories, it's easy to see how people can easily get too many calories.

Weighing your ingredients, especially when you are starting out at eating healthier, is a great idea. Knowing just what that 4 ounces looks like is important and by weighing your food you'll learn exactly what a portion should look like.

Once you've decided what you're having for the main course it's time to think about the carbs. This is where it's good to think about that Blue Plate Special as a meat, a starch and a veg. There are lots of choices here and a serving generally works out to somewhere between 150 and 250 calories. Keep in mind that making the higher fiber choice will be the best quality calories.

Adding up what we have so far gets us to somewhere between 300 and 450 calories for the meal. That can be a bit of a wide mark, but for the most part it'll balance out day in and day out.

So that leaves the veggies. Quite simply, eat what you want. Veggies can be a bit all over the map, with some being as little as 25 calories in 4 ounces up to as much as 100 calories. These are the best quality calories, however, and getting more veggies is the path to being healthier.

Altogether, this will add up to between 325 and 550 calories for the whole meal (from the lowest combination to the highest).

Note that this doesn't always have to be a meat, starch and a veggie on your plate like you might get at the diner. Take a dinner meal of Lentil Chili with a side salad, as a good example. There's plenty of veggies in the chili and the lentils provide great quality carbs and fiber as well as terrific quality protein. The rest of the protein comes from the cheese and there's even more veggies in the side salad.

Added up, the rule of thumb for a complete dinner meal should be about 500 calories and 10 grams of fiber. Some meals will be more and others less. Finding recipes in this range are going to be satisfying.

This is about is finding the right balance in a particular meal – protein, high quality carbs and fresh veggies. Eating great food is the key to your success, after all.
