A quick method to promote fat loss, the Kekwick diet -- or Fat Fast diet -- is one of many fad diets available. Originally developed by Alan Kekwick and Gaston Pawan, the plan initially restricts participants to 1,000 daily calories, with 90 percent of these calories provided by fat sources.
How Does It Work?
Due to the low calorie restriction and the high-fat content of the diet, the body uses fat as a fuel source. There are three steps to the Kekwick Diet. During step one, participants eat five 200-calorie meals for four to five days. An example meal would be 1 ounce of tuna salad with 2 teaspoons of mayonnaise. The second step allows 1,200 daily calories in four small meals for one week. Two ounces of beef cooked in 2 tablespoons of olive oil would be considered a meal. In step three, dieters return to the step one restrictions. Overall, the diet goal is high fat and low carbohydrates, resulting in body-fat loss.
Before starting any type of restrictive diet, consult with your physician. According to the American Heart Association, a high-fat diet can increase heart disease risk. A healthy diet and physical activity are recommended for weight loss. An April 2011 article in "Eating Behaviors" supports this approach. The study participants maintained their weight loss with a low-calorie diet and regular intake of whole grains and vegetables.
