Are you worn out? Feeling down? Having trouble sleeping? Frustrated by your inability to lose weight? Tim Ferriss, author of the 4-Hour Body and self-proclaimed human guinea pig, has spent years researching and testing unusual health and fitness theories on his own body. Those he’s found safe and effective have made him.
Here he tackles some of your biggest complaints – from fighting a slow metabolism to experiencing the blues to difficulty sleeping. His solutions will show you how to supercharge and reshape your body with very little extra effort.
1. Supercharge Your Metabolism: 5-Minute Deep Freeze
By taking a cold shower anywhere from 5 minutes to 30 minutes, you can jumpstart your metabolism. That’s because cold temperature activates brown fat, the fat-burning fat tissue in your body that burns energy to keep you warm. When taking a cold shower, you may experience some shivering, which indicates that you’re using energy to keep your body temperature up.
Try taking a quick shower in the morning or night. Start with 2 minutes of warm water to get your body temperature up, then switch to cold and work toward keeping the water temperature under 60 degrees. Over time, your body will become less sensitive to this drop in temperature.
2. Supercharge Your Mood: Kimchi Kick-start
Millions of people take prescription SSRI antidepressants to keep levels of the neurotransmitter serotonin high so they can maintain a good mood. However, most people don’t realize that more than 90% of the body’s serotonin is produced in the gut, which is why scientists often refer to it as the “second brain.”
Science has suggested that if you eat fermented food regularly, such as kimchi (Korean pickled cabbage), its healthy, probiotic bacteria will help the serotonin in your gut move to your brain. Eat 4-5 tablespoons of kimchi or any lacto-fermented food such as sauerkraut or plain yogurt daily to chase the blues away.
