Spices are a great way to add flavor to recipes and meals without added calories or salt. Some spices have a thermogenic effect, which means eating them boosts metabolism so you actually burn some extra calories eating certain spicy dishes. Try experimenting with these:

Cinnamon

Cinnamon is a delicious way to add sweetness to a dish without having to use sugar. It is also a great spice to cook with and can add a lightly spicy taste to savory dishes. Several studies, including one published in the Diabetes Care Journal, have shown that cinnamon can boost weight loss. The weight loss properties of cinnamon stem from the ability to help keep blood sugar levels under control, therefore decreasing the amount of insulin produced after a meal. Higher levels of unnecessary insulin result in the production of excess fat. Cinnamon has also been found to slow down gastric emptying, making you feel full longer.

Cayenne

This piquant spice contains capsaicin, which has long been regarded for its fat burning ability. Cayenne has thermogenic properties that increase calorie burning. It also helps with weight loss simply because the spicier a food is, the less you eat and slower you eat - so you feel full on less food.  If you don’t care for spicy pepper, evidence has shown that even sweet peppers have a thermogenic effect, boosting calorie burning in the body. Cayenne also increases fat oxidation, helping you shed unwanted body fat.

Black Pepper

A staple in any cooks’ kitchen, not only jazzes up a recipe, but it helps boost metabolism by as much as 8 percent because of the compound, piperine, found in black pepper. This spice has been shown to aid in digestion and nutrient absorption. To maximize the results, use fresh black pepper instead of ground pepper.

Mustard Seed

Just like the hot spice cayenne - mustard seed also has a thermogenic effect on the body. According to a Canadian study, eating spicy foods such as mustard seed can burn an extra 1,000 calories a day, with one tea spoon potentially boosting your metabolism by 25 percent.

Ginger

Not only is ginger delicious with just about everything, it also has been found to help with weight loss and satiety. According to a study at Columbia University and the New York Obesity Research Center, adding one teaspoon of dried ground ginger to a meal or having a cup of ginger tea with breakfast resulted in 43 more calories burned after eating.
