Top 10 superfoods for weight loss

Discover the science behind these foods that help you lose weight.

Kiwi

Slimming powers. A large kiwi contains 84 milligrams of vitamin C, more than the recommended daily allowance. Vitamin C helps form carnitine, a compound that carries fat into cellular mitochondria, where it is burned for energy during exercise.

The test. People with low levels of C in the blood burned 10% less fat per pound of weight while walking than those with normal levels of C, a study of Arizona State University. When subjects received a dose of C, its ability to burn fat quadrupled.

Wild Salmon

Slimming powers. The omega-3s from fish may help you burn fat more effectively. These alter the expression of certain genes, making your body burn fat instead of storing it.
The test. In a study of Public Health Nutrition which analyzed the diets of 35 000 women, those who ate fish two to four times per week had the lowest basal metabolic rates, a common measure of body fat.

Quinoa

The test. People with reduced calorie diet who ate 115 grams of protein every day lost 22% more fat after four months than those who ate 70g per day, according to a report in The Journal of Nutrition.

Lentils

Slimming powers. These vegetables are rich in resistant starch, a carbohydrate that could promote the burning fat and shrink fat cells.

The test. In one study participants who consumed a meal with 5 grams of resistant starch - which is in ¾ cup cooked lentils - burned 23% more fat per 24 hours than those who did not consume starch, concluded Researchers at the University of Colorado.

Olive oil

Slimming powers. Monounsaturated fats found in olive oil could potentially turn on genes related to fat burning and storage.

The test. People in a low-calorie plan emphasizing monounsaturated fats and complex carbs lost almost double the weight than those who consumed the same calories but less fat and total protein and carbohydrates, a study of the Archives of Internal Medicine.

Eggs

Slimming powers. Eggs are loaded with choline, a compound known because it helps block fat absorption.

The test. People who consumed eight weeks of two eggs, toast and jelly for breakfast, five days a week, lost 65% more weight than those who ate breakfast with the same calories, but without the eggs, according to a study published by International Journal of Obesity.

Yogurt

Slimming powers. Free Greek yogurt or low fat regular and yogurts contain 20% or more of the daily dose of calcium. The mineral slows the production of cortisol, a hormone that promotes the accumulation of fat in the abdomen.

The test. People in a low-calorie diet that included yogurt lost 81% more abdominal fat than those on a similar plan but without yogurt, a study from the University of Tennessee.

Yams

Slimming powers. These contain the same resistant starches the lentils, which help the body burn fat. These starches may also increase the production of the peptide hormone that point to the brain when to stop eating.

The test. After a breakfast and lunch including resistant starches, subjects consumed 10% fewer calories over a period of 24 hours compared with similar foods with placebo, according to a study by the University of Surrey.

Edamame
