Ginger

It is believed that ginger and closely related spices have particularly advantageous metabolism-boosting properties. For instance, according to a study, drinking hot water with 2 grams of ginger powder mixed in it along with a meal will help you burn up to 43 more calories than just sipping hot water.

This hot ginger beverage may also help people feel more satisfied and less hungry (fullness). Another spice from the ginger family called grains of paradise might have comparable results. According to a study done on 19 healthy males, those who took a 40 mg extract of grains of paradise burnt 43 more calories in the two hours that followed than those who took a placebo. However, the results may differ from person to person, according to the researchers.
