These are spices you definitely want more of you're looking to lose weight. They boost the body's metabolism thus ensuring that excess and redundant body fat gets burnt. The ability of capsaicin (an element of both) to burn the fat helps the body control its LDL (bad) cholesterol, too.  Capsaicin can also reduce the risks posed by ulcers by preparing the stomach cells to counter/resist any ulcer inducing bacteria. Coriander and black pepper has similar metabolism-boosting powers to chili. Cumin seeds are rich in thymol, an enzyme that boosts the digestive system in the body, has extraordinary fiber content and amazing laxative properties that can be a cure for constipation. There is also a component called cuminaldehyde present in cumin that can fight cancer and tumors.  Cumin is also great for maintaining memory and mental faculties owing to the presence of minerals such as vitamin B6, riboflavin, niacin and zea-xanthin. Consumption of cumin seeds is the most natural way to cure anemia as cumin seeds are rich in iron, too. They are also rich in potassium which is capable of promoting the flow of fluids in the body, helping to maintain blood pressure. Sage is a spice that is rich in memory enriching compounds called phenols. These phenols prevent or slow down the aging of the brain by breaking down the chemicals that normally lead to aging, preventing them from having any effect. Sage is also effective in controlling the initial symptoms of Alzheimer's by preventing destruction and exhaustion of the brain chemical acetylcholine which is involved in preserving the normal memory functions of the brain. Why? It's practically a wonder spice. It can boost the memory immediately! Include cinnamon in your diet before you go to study or take a test. It can help with weight loss, too.  How does it do it? Cinnamon does a great job of stabilizing the sugar and glucose levels in the body. When this spice is combined with a food rich in carbohydrates it ensures that the brain gets a steady dose of glucose instead of the glucose-bombardment carbs normally provide. Consuming about ½ teaspoon of cinnamon daily can reduce your cholesterol and triglyceride levels by up to 30%.  This is a near-to substitute for sugar and can be used in drinks, cereals, desserts and muffins. A small amount (as low as 1/10th teaspoon) of saffron daily is enough to keep you away from depression. This spice offers stiff resistance to depression by aiding the brain in the production of serotonin which is known to act as a natural mood booster. Rosemary should also be taken in moderation. Carnosic acid, a substance found in rosemary, has been found to protect the brain from any damage that might be caused by free radicals. This protection means the risk of Alzheimer's, stroke and other neurodegenerative diseases can be kept at bay. It is also highly effective in improving concentration and memory when used in aromatherapy.

Summary:
Try more chili or cayenne pepper for an energy boost. Go for more cumin for your blood and brain. Use more sage for your memory. Garnish everything with cinnamon. Use more saffron and rosemary.
