The Weight Watchers diet is a classical low-calorie, healthily-balanced diet. You can eat anything you like in moderation, as long as you follow the food pyramid guidelines, with half of your energy coming from slow-release carbs, a third from protein and a sixth from fats.

Sample day's food:
Breakfast:
1 egg
1 slice of wholemeal toast with low-fat spread
1 piece of fruit
Tea or coffee
Lunch and Dinner:
Crudites or salad, with 2 teaspoons of vinaigrette, or soup
Lean meat, fish or two eggs
Cooked vegetables and/or small quantity of carbohydrates
Dessert: fresh fruit or low-fat yoghurt
Water
Optional: 1 glass of wine a day
Snack: Cheese and biscuits, fruit
Tea

The diet is harder to follow alone and weight loss is quite slow. Don't give up, it may take several months ot get down to your target weight.
