Your metabolism is always running, even while you’re asleep. Its rate is determined largely by your genetics. A thermogenic like caffeine or chili extract can temporarily increase the rate, but long-term alterations require lifestyle changes. That’s what a news release from the Texas A&M School of Public Health suggests.
Because muscle burns more calories than body fat, weight training can help increase muscle mass and metabolism. Hydration is also important, and eating right is another productive change you can make, getting more leafy vegetables into your diet and not skipping breakfast. You also need to get enough sleep because your metabolism can’t run efficiently without the right amount, usually defined as between 7 and 8 hours.
Losing just 2% of your body weight in fluids can have a negative impact on performance. Realizing the importance of hydration for competitive athletes, a study published in the International Journal of Sport Nutrition and Exercise Metabolism put plain water up against coconut water to see which worked best.
Ten male volunteers in their 20s cycled on a stationary bike for an hour drinking 250 ml of water or coconut water every 15 minutes. Then they competed in a 10 km time trial. They could drink as much as they wanted during the last 5 minutes of the sub-maximal ride and the time trial.
There weren’t any significant differences between rate of perceived exertion, feeling of fullness, rating of thirst or time trial performance. The only real difference was subjects assigned coconut water drank less compared to the plain water group.
