The Theory:

The zone diet works on the theory that excess insulin, a hormone which helps control our blood sugar levels, makes us fat and keeps us fat. By regulating our blood sugar levels and keeping our levels of insulin in a tight zone the body burns fat more efficiently.

You need to get the perfect balance of carbohydrates, proteins and fats in every meal. Achieving this perfect balance effectively means following a low-carbohydrate, high-protein diet that includes moderate amounts of fat

Food restrictions:

Breakfast cereals, rice, potatoes, pasta, noodles, bread, bagels, croissants, muffins, crisps, pastries, pies, chocolate, sweets, sugar and preserves. (These have the greatest effect on blood sugar levels and insulin levels).

Recommended:

Olive oil, avocado and nuts. ( Rich in monounsaturates)

The diet creator recommends dividing your plate into three equal sized sections and then filling one section with low-fat protein such as chicken - making sure it's no larger or thicker than the palm of your hand - and the remaining two sections with vegetables and fruit. Adding a little olive oil, avocado or a few nuts will help to boost intakes of monounsaturates!

You can lose at least 5lb in the first two weeks, followed by 1-1.5lb every week after this.

Pros!

There are fewer dietary restrictions than many other low-carb plans. It recommends eating more fruit and vegetables which are good for us. It encourages us to cut out fatty foods such as crisps, cakes, biscuits, and chocolate.

Cons!

The diet is complicated and time consuming. It recommends that we cut out some very nutritious foods, which are a good source of carbohydrates, but are also packed full of fibers and important vitamins and minerals, e.g.) wholegrain cereals have fibre, B vitamins and iron. Cheese has calcium and zinc.
