Coffee Can Increase Metabolic Rate
Your metabolic rate is the number of calories your body burns at rest. It is sometimes also known as the basal metabolic rate (BMR) or resting metabolic rate and can have variables based on lean muscle mass and other factors. What if there was a way to raise your metabolic rate with no extra effort, or while doing absolutely no extra physical activity? That way is coffee.
A study conducted as far back as 1995 and published in The Annals of Nutrition & Metabolism (Koot et al.) studied the effects of coffee drinking and metabolic rate, with and without caffeine. Subjects given coffee with 200mg caffeine were found to experience increases in a metabolic rate ranging from 3-11%, with much of the increased burning of calories coming from the oxidation of fat in the blood.
Another study published in the American Journal Of Physiology found differences in the metabolism boost to be as high as 29% in lean individuals, while in obese persons the increase in metabolic rate stands at about 10%.
Lastly, another study published by the American Journal Of Physiology showed differences in metabolism between young men and older men and discovered that both groups of men experienced similar thermogenic outputs following caffeine intake, but the younger group of men experienced the increased release of free fatty acids, translating to higher metabolisms.
Coffee Can Boost Physical Performance
While this is not a direct increase in metabolic rate, what is quite curious is the fact that by increasing your physical performance, you indirectly improve your metabolism. Especially if weight training and muscle cell mitochondria become more efficient in burning fat for fuel, which in turn keeps us leaner year round.
This is the reason why many performance athletes supplement with caffeine (or drink black coffee) prior to working out, as the increased firing and improved contractility of muscles leads to greater calorie burning and can translate to improved metabolism long term.
Coffee does certainly favor increased metabolism, allowing you to burn more calories while even at rest. Coffee also increases thermogenesis, which is calories used for heat, as evidenced by higher body temperatures while using caffeine.
Just be sure to have your coffee black, or as close to black as possible, because loading with sugar and creamer adds unnecessary sugars to this super beverage and can negate the fat liberating effects since insulin gets involved. Types of coffee to consider? Maybe try some coffee from Panama or Costa Rica or Nicaragua.
