Do you have less energy than you did before cancer? Do you sometimes crash in the middle of the afternoon? If you answered Yes to these questions and wonder why your energy is zapped, you may want to consider something completely outside the realm of cancer. Like your diet.

Canyon Ranch nutritionists say lack of energy is not always related to diet. It can also stem from lack of sleep and exercise, depression, anxiety, low-grade infection, medication, reaction to alcohol, and caffeine withdrawal or dependence. But diet surely plays a part, and sometimes a very large part. So in the interest of energetic and healthy living, you might want to give some thought to these energy-building diet tips.

Start the day with a healthy breakfast. When kids don't eat breakfast, they don't think as clearly and don't do homework as well as their well-nourished classmates. Adults are no different. Everyone needs a jump-start in the morning. It's good for metabolism and blood sugar. It's good for the brain.

Eat every three to four hours. Blood sugar levels are at their lowest about four hours after a meal. Low blood sugar = low energy so to keep your motor running, eat breakfast, lunch, an afternoon snack, and dinner. Some people prefer a mid-morning snack too.

Don't undereat. Overeating leads to weight gain. But undereating doesn't lead to long-term weight loss. It leads to low energy. So keep eating -- just make it healthy.

Eat balanced meals and snacks. Make sure protein, and even a little healthy fat, accompany any other foods you eat. These two items slow digestion and absorbption of carbohydrates, leaving us with a longer-lasting supply of blood sugar, a controlled hunger, and sustained energy. Good sources of protein include: low-fat cheese, eggs or egg whites, fresh fish, nuts and seeds, nut butters, beans, soy, chicken and turkey, and canned tuna or salmon.

Eat mindfully. Don't just eat. Pay attention to your appetite and hunger. Eat on a schedule -- but only until your hunger is satisfied. This way, you'll never end up with that starving feeling.

Thanks again, Canyon Ranch experts, for your continued wisdom.
