Don't let your health take a back seat to anything.  If you have an ailment or problem, or you don't feel comfortable or confident with how you look or feel, all parts of your life are affected.  It is as though you are looking at the world through cloudy eyes.  Poor health interferes with everything -- relationships, business, family harmony -- so you must make health a top priority.  Take time for nurturing your wellness. If you don't take time for wellness, you are going to have to take time for sickness.

When a variety of foods are eaten in their natural fresh state, you can most effectively digest, assimilate, and use the nutrients. Thus, you feel satisfied with small amounts of food.  On the other hand, when your diet consists of lots of canned, frozen, packaged items ( especially those void of much nutritional value because of processing), and fast foods, the body does not get its proper nutritional requirements met and thus, after a meal, you will feel hungry -- which leads to overeating.
When you overeat, you place unneeded stress on the body that results in a feeling of fatigue as well as inevitable fat deposition.  In fact, eating one meal a day in an amount that makes up for the other missed meals, even if the meal is a healthy, unprocessed one, will eventually add on extra pounds if you keep it up.

I suggest that you design a 21 day program that will help you achieve your goals.  Make an agreement with yourself that for 21 days you will develop new, health, eating habits.  Perhaps you might agree to include two pieces of fresh fruit in your diet every day.  Or perhaps it's something as simple as eating slower, drinking more water, chewing your foods more, or leaving the table before feeling too full.  Whatever you decide, stick with it for 21 days and you'll discover your resistance to the change is gone at the end of that time and your new habits will feel good to you.
