Keep in mind that the health experts all agree on one thing: Obesity is on the rise because people eat too many calories and do not exercise enough. Portion control is a very important factor for losing-weight, but to attain a fit and healthy physique exercise is also a must.

Now that you know portion sizes today are far larger than you really need, what are you going to do the next time you go out to eat? Try the following 3 tips and watch as your waist begins to slim and your confidence soars.

Trim-Down Tip #1: Re-program Your Mind

I'm sure your mother did a great job when she taught you to "clean your plate." The problem now lies in the fact that your plate is usually loaded with more than 3 times the calories that you really need. So what's the solution?

Realize that it is O.K. to leave food on your plate. Eating everything on the plate is probably a habit now, but it is one that you can break. Focus on how you feel halfway through your meal. Are you full? If you are beginning to feel full then stop eating. Don't worry - your mom won't send you to your room!

Trim-Down Tip #2: Slow Down

I know that this is a tough one - so bear with me. These days we are in such a hurry, we rush to work, rush to lunch, rush through errands and then rush home. So it is no wonder that food consumption is no exception. Most meals are devoured before your stomach has the chance to let you know that it is full.

Eat your next meal slower than usual. Chew each bite thoroughly, engage in conversation and pay attention for signs that you may be getting full. Once you realize that you are full, stop eating. Congratulations - you just tailored your portion down to its proper size.

Trim-Down Tip #3: Go Halfsies

I understand that it may be very difficult for you to leave food on your plate, even though your mother isn't looking over your shoulder, and even if you eat slowly. No problem - you just need to do some strategic planning. The next time you go out to eat do one of the following two options.

1. Share an entr'e with a friend and order salad or soup to start your meal. This will cut your calories down dramatically, while still giving you the satisfaction of clearing your plate.

2. If sharing isn't an option then ask your waiter to bring a to-go box along with your order. As soon as the food is placed in front of you put half of it into the to-go box. You are now left with a reasonable portion and even have your next meal taken care of.

Remember, you are in charge:

There may be certain aspects of life that you do not have direct control over, but what ends up in your mouth is not one of them! You control what you eat. When faced with extra large portions exercise your right to chose wisely and your body and waistline will thank you for it. Couple this with a regular fitness routine and you will find that reaching and maintaining your goal weight is easier than ever.
