Caffeine- The bitter, white crystalline xanthine alkaloid caffeine is found in tea, coffee, soft drinks, chocolates, pain relievers, and a variety of over the counter medications. It is a psychoactive stimulant drug that causes increased alertness by stimulating the central nervous system. For the same reason, many people feel more energetic after consuming it. It even elevates the mood but these effects do not last for long. The effects of caffeine usually last for about five to six hours, though caffeine sensitivity varies from person to person. It has been found that people who consume lot of caffeine on a daily basis soon develop less sensitivity and may need to increase their intake to enjoy the same effect. Being a diuretic, a person consuming caffeine may have to urinate more often.

Cinnamon reduces fasting blood sugar levels.

Green Tea Extract increases energy expenditure and affects fat oxidation, which therefore promotes weight loss by increasing the body's metabolism.

Raspberry Ketones- Red raspberries contain a phenolic compound, which is the main aroma in red raspberries. This raspberry ketone is being used in cosmetics and perfume industries, but also as a food additive. While the use as a weight loss agent has not yet been clinically tested on human subjects, preliminary research in lab mice has shown that raspberry ketones in high doses show a norepinephrine induced lipolysis. This leads to the effect that even a diet high on fats did not result in higher body weight. This fact has immediately led to the embrace of raspberry ketones by the weight loss and body building communities, despite the fact that raspberry fruits would be much healthier, containing ellagic acid, catechins, salicylic acid, and various other polyphenols, besides large quantities of Vitamin C.
