Health Castle offers "Ten signs of a fad diet":

1. It promises massive weight loss (1 - 2 lbs per week)

Dr. Barry Sears is careful when he declares a standard weight loss on Zone diet. He considers that anything between 1 to 1,5 lbs per week is satisfactory. "It will be impossible to lose more than one to one point five pounds of fat per week. Anything over that is loss of retained water", says Sears himself on his daily "Ask Dr. Sears" column at DrSears.com. FAD. 2. It does not suggest you that you consult with a registered dietician or nutritionist

"Any change in diet (for better or worse) will affect metabolism of drug(s) you are taking. Always consult with a physician before starting Zone Diet or any other dietary plan", says Dr. Sears in various interviews and discussion lists. Not FAD. 3. It encourages you to eliminate certain food groups (e.g. "low carb diets", "low fat diets")

This is untrue for Zone diet. Dr. Sears says: "No food is forbidden in Zone." Zone diet considers "unfavourable" mostly high glycemic foods and foods high in saturated fats. Not FAD. 4. It offers rigid menus

Difficult-to-prepare meals, plenty of measuring and counting, rules that are easy to misinterpret, Zone subscribes to that. FAD 5. It neglects active living or lifestyle changes

The Zone diet has impressive instrumentary and regulation for dining out or for fast food. On other hand, there's no problem if you step out of Zone now and then. Here are some soothing phrases from Dr. Sears himself: "The Zone diet is free of guilt" or "The Zone is just one meal away". I'm quite UNDECIDED about this one. It is clear man has taken some time to think about it. 6. It harshly limitates daily calorie intake

Indoor air pollution in form of dander, dust and pollen particulate matter can be a real irritant for suffers of asthma, allergies and other respiratory conditions. In addition to removal of all direct irritant sources and minimizing irritant containment materials in your house, you should also consider indoor ventilation and filtration system of home.

Environmental control is key to reducing exposure to indoor and outdoor allergens. Keeping a clean house free of dust, dander, smoke, pollen, and other airborne particulate matters will help to reduce irritation and effect on family members with respiratory difficulties. Air cleaners, filters and hepa filters can play a role in helping to control or reduce exposure to indoor and outdoor allergens.
