Ever wonder why some people swear by a low-carb diet while others claim only a low-fat diet works for them? According to fitness trainer and author of The Diet Solution, Isabel De Los Rios, the reason is all about your body’s metabolic type.

The Diet Solution program is a holistic diet and lifestyle plan that combines foods matched to your metabolic type along with a mind-body connection.

“Most diets don’t work because people eat the wrong foods. When you start eating the right kinds of natural foods specific for your metabolic type, you will start to lose weight, enjoy beautiful skin, and feel more energized,” says De Los Rios, who created The Diet Solution after years of helping people lose weight.

“It is a completely natural way of losing weight that works and empowers nonbelievers that it is possible to lose weight,” she says.

This is not a quick fix diet with fast results; instead expect to lose one to two pounds per week, which is the amount recommended by most diet and nutrition experts.

The Diet Solution: The Theory

The Diet Solution is based on the theory that losing weight starts with an understanding of your body’s metabolic type, calorie requirements, and specific amounts of carbs, protein, and fat in your meals.

According to De Los Rios, everyone falls into one of three metabolic diet types – protein, carb, or mixed -- and if you eliminate the foods that don't suit your metabolic type, you will lose weight.

"Eating refined carbs will add fat to some people while having little impact on others, so if you avoid the foods according to your type, you will lose weight," De Los Rios says.

The program also makes assertions beyond weight loss and claims to control blood sugar levels, blood pressure, and cholesterol; improve other health-related conditions, improve skin, and increase energy levels.

The Diet Solution: How It Works

First, you determine your metabolic type by filling out a questionnaire. Next, you calculate your calorie goal. You then follow the six-week meal plans that outline food choices for each meal and snacks.
