I totally agree there RobinN. I have swapped junk food, fast food, processed food, MSG based ingredients, gluten based ingredients for:
Fresh fruit, fresh veggies, high protein low fat Greek Yogurt, high protein low fat white organic chicken meat, high protein hard boiled eggs (no butter or salt), absolutely no bread, no high sodium laden soups or canned goods, no diet soda or artificial sweeteners and a lot of home made meals. If there's a favorite recipe, modify it to suit your needs.
Watch out for glucose levels lower than 100 since they may also cause one to pass out. Keep taking electrolytes with sports drinks that have no caffeine, no ginkgo biloba, no ginseng, no high fructose corn syrup and eat small meals all day on a regular basis.
I've been doing this for several years along with a workout that includes a 2 mile walk in cool weather or at least a half hour on an indoor treadmill. If you have been working out, keep it up. If you are starting an exercise regimen, with your doctor's permission, take it easy until you can add more intensity to the workout. Although swimming is a high calorie burning workout, personally go for the equipment that is more safe. Have a person by your side for a safety guard.
Frozen dinners have to either be ice cream, low sodium dinners (really rare there) or frozen organic vegetables. I feel really strongly about organic foods, especially because of growth hormones.
My chocolate/sweet fix is from a calcium chew. Healthy, and fights osteoporosis.
Keep a written log of everything you eat.
