Here are some tasty options that will fuel you up and generate weight loss. Make these foods a part of your daily diet and watch the pounds come slipping off.

1) GRAPEFRUIT

Scientific study proved the effect of grapefruit on weight loss and found that eating half a grapefruit before a meal can actually help people drop weight. The researchers studied the effect of grapefruit capsules, grapefruit juice and real grapefruit. All three seemed to help, but the folks eating the real grapefruit got the best results. The mechanism isn’t completely understood, but the results speak for themselves. As an added benefit, grapefruit contains cancer-fighting compounds. And half a grapefruit has only 39 calories.

2) PUMPKIN

You may know this vegetable for its central role in many festivals, but it’s also one of the greatest weight-loss foods ever. Plain old canned pumpkin is absolutely loaded with fiber and has a mere 40 calories. Dozens of studies confirm that high fiber intake is associated with a host of health benefits, including weight management. Pumpkin is also among the easiest food in the world to prepare.

3) GRASS-FED BEEF

Meat is a great diet food — if it doesn’t contain antibiotics, steroids and hormones. Eat grass-fed beef and avoid the health concerns that go along with eating meat while getting all the terrific benefits. Buffalo burgers are a good alternative if you can’t find grass-fed beef. High-protein diets are associated with weight loss for a variety of reasons: Protein stimulates metabolism, helps you feel full longer and helps decrease the desire to overeat. Grass-fed beef has a high omega-3 content, giving you multiple health benefits into the bargain.

4) SEA FISH

Sea fish might just be one of the greatest health bargains of all time, and they’re a boon to anyone wanting to lose weight. First of all, they are loaded with protein, which helps stabilize blood sugar, makes you feel full and helps stimulate metabolism. Second, they’re a great source of omega-3s, which not only strengthen the cardiovascular system but also are helpful in boosting mood.

5) GREEN TEA

This natural weight-loss stimulant might not be a food, but green tea is still a great slimming solution, not to mention that it’s rich in antioxidants, promotes heart health, aids digestion and regulates blood sugar and body temperature. It raises the metabolic rate and speeds up fat oxidation, thus helping people lose weight. Some research has shown that five cups a day is the magic number for fat loss.
