Spices that I added in my food which aid in weight loss

It can found in the form of powder or capsules.

Studies show cayenne pepper can speed up metabolism and suppress the appetite. The hot and spicy taste of cayenne pepper comes from capsaicin, a compound found in many hot peppers. Capsaicin is known to boost metabolism, causing the body to produce extra heat and burn more calories for fuel. Research suggests that after consuming foods with capsaicin, the body’s metabolic rate (aka energy use) can increase 15 % for up to two hours. Other studies suggest capsaicin also increases fat oxidation, allowing the body to better use fat as fuel.

A more significant effect of cayenne is appetite suppression. It helps to cut down the craving for fatty, salty and sweet foods. 
Add some cayenne powder into your foods such as vegetables, soup or meat to boost your metabolism. 

But don't expect the pounds can be cut down by using cayenne. Regular exercise and clean diet are necessary too. 

cinnamon also comes in powder form

Cinnamon is rich in manganese, iron, calcium and fiber. It has been used since medieval times to cure diarrhea, indigestion and bloating. In addition, it helps prevent the spread of cancer cells, the formation of stomach ulcers, and assists in curing bacterial infections. Cinnamon lowers blood sugar levels along with bad cholesterol levels (LDL) while having no effect on the good cholesterol (HDL). Hence, it’s beneficial for both heart and type 2 diabetes patients. The lowering of blood sugar levels and improvement in cholesterol ratios helps to reverse insulin resistance or pre-diabetes. Since cinnamon is sweet to the taste, it also satisfies the craving for sweet foods that generally afflicts diabetics.

Cinnamon has a regulatory effect on blood sugar levels and simultaneously increases insulin levels in the body. It imitates the biological activity of insulin and increases the metabolism of glucose. Since high blood sugar levels can lead to increased storage of fat by the body, cinnamon helps prevent this increased storage of fat and enables you to lose weight. In addition, it influences the manner in which sugar is metabolized by the body and prevents the transformation of the metabolized sugar into fat. Cinnamon also delays the passing of food from the stomach into the intestine. Hence, you feel satisfied for a longer time and eat less. Cinnamon also helps the body to process carbohydrates more efficiently and this assists you in losing a few pounds. Studies show that abdominal fat is more sensitive to the effects of cinnamon than fat from other parts of the body.
