2. Boosts Metabolism
Coffee increases metabolism. It also causes thermogenesis, which is a way the body makes heat and energy from digesting food. This can result in the loss of some extra calories.
The number of calories we burn at rest is called the Resting Metabolic Rate (RMR).
The higher our metabolic rate, the easier it is for us to lose weight and the more we can allow ourselves to eat without gaining.
Studies show that caffeine can increase the metabolic rate by 3-11%, with larger doses having an even bigger effect. Most of the increase in metabolism is caused by an increase in the burning of fat.
In one study, the increase in fat burning in lean people is as high as 29%, while in obese individuals the increase is about 10%. The effect also appears to diminish with age and is more pronounced in younger individuals.
3. Burns More Fat Even During Exercise
Coffee combined with exercise turns out to be one of the effective ways to get slim. By using the basic principles of how caffeine helps burn fat exercise burns up more fat. Thus, simply drinking a cup of coffee before you workout you can take diet and exercise to a whole new level of weight loss.
For enhanced effects, the best time to drinking coffee is 20-30 minutes before you start to exercise. The positive effects of coffee are best appreciated 20-30 minutes after drinking. Increasing your activity and exercising, burns off fat with coffee.
Caffeine can improve athletic performance via several mechanisms. One of these mechnisms is to increase mobilization of fatty acids from the fat tissues. Studies show that caffeine can improve exercise performance by 11-12%, on average (3, 4,5,6).
