Foods high in calcium
If you want to increase your metabolic rate, it is very important to eat plenty of foods high in calcium.
A study at the University of Tennessee confirmed that people who consume between 1,200 and 1,300 milligrams of calcium a day lose twice as much weight as those who consume it in smaller amounts.
Omega-3 fatty acids
Omega-3 fatty acids are primarily found in fish, but they are also present in nuts and seeds, flax, and hemp seed oil.
These foods speed up your metabolism because they reduce the production of a hormone called leptin (a natural chemical that slows down your metabolism).
In fact, a study by the Mayo Clinic found that African tribes that included plenty of fish in their diet had five times lower leptin levels than those that did not consume it.
