What is an example of a calorie-restricted diet?

A calorie-restricted diet must balance carbohydrates, proteins and fats by choosing foods packed with nutrients and not many calories.

Here is one daily diet a proponent uses:

• Breakfast: a homemade mega-muffin with about 30 ingredients including rice bran, psyllium husk (the active ingredient in Metamucil), brewer's yeast, raw wheat germ, strawberries and one carrot
• Lunch: a roast beef sandwich without the bread, or a protein bar
• Dinner: canned pink salmon, zucchini and broccoli
• Dessert: fruit salad topped with whey protein
