Before we proceed to giving you three diet foods to help weight loss, here are some insights that would help you keep off the weight as well. Some people who find themselves emotionally disturbed often turn to food for comfort. When there are stressful events at home and at work, they may unconsciously resort to food—often high calorie foods and sweets that end up being deposited as body fat.

Emotional problems are not the sole cause of increased food intake leading to weigh gain, of course. There are many others such as a person’s metabolic rate, the level of physical activity and overall health.

But there are many ways to lose weight, a person who is motivated would only have to choose which method suits him or her best. Here are three diet foods that are guaranteed to burn that excess fat.

#1: Green Tea Extract

Green tea is the processed leaves of Camellia sinensis and is originally from China, though many other countries produce it today. Western cultures have already embraced green tea because of its many virtues. And there are now a number of green tea varieties that have been used as ingredients in dietary supplements that help weight loss, various types of health food, as well as cosmetics.

When it comes to increasing metabolism and the rate of burning fat, green tea extract is one effective agent. The secret ingredient behind green tea’s weight loss virtues is essentially a chemical compound called catechins. The polyphenols and to some extent the caffeine in green tea extract increases oxidation of fat in humans. Studies show a significant decrease in the body mass index (BMI) of study participants and in addition to that, tests showed that they have low density lipoproteins (LDL) or bad cholesterol as well.

Studies on the benefits of green tea reveal that it also improves overall health such that people have lower risk of heart conditions and cancer. Green tea extract is also believed to have anti-oxidant effect.

#2: Pears

According to the United States Food and Drug Administration, pears have more fiber than previously thought and they even have more fiber content than apples. Any medium-sized pear contains approximately six grams of fiber. In addition, pears contain pectin which causes blood sugar levels to rise in between meals, making it unnecessary to take a snack in between the major meals of the day. In effect, if you eat more pears, you could lose more weight.

#3: Lean beef

Lean beef is rich in the amino acid "leucine" which in one study caused loss of weight in study subjects who ate 10 oz. of beef every day. The subjects were limited to a 1,700 calorie diet. The amino acid that’s found in lean beef is also found in fish and dairy products. You maintain your muscle bulk while the excess fat is burned. It has also been shown that lean beef reduces the feeling of hunger among those who ate lean beef regularly.
