Foods Rich in B12
Eggs, milk, low-fat cheese and cereals that have been vitamin-enriched are all good sources of vitamin B12. Some sources state that B12 increases the body's fat-burning ability. Every gram of fat equals 9 calories, so when you burn fat, you burn calories, too. Vitamin B12 is also known to fight fatigue and speed up the metabolism, which are benefits that can give a boost to any dieter.
