@reverseinsulinresistance: You’re burning fat with muscle alone. But you have a second system most people never switch on. Brown fat burns fuel to produce heat. Our homes are heated and our bodies rarely feel cold. So brown fat stays switched off. When your skin senses cold, it signals your brain. Your brain activates brown fat. Inside its mitochondria, a protein called UCP1 releases energy as heat instead of storing it. You burn calories without doing anything extra. At the National Institutes of Health, five healthy men slept at 19 degrees for a month. Their brown fat increased, and so did their insulin sensitivity. Set your bedroom to around 19 degrees overnight. Finish your shower with two minutes of cold. Get outside in the cold once a week without your coat. If you want the exact natural protocol I use to help reverse insulin resistance, reduce cravings and support fat loss naturally, comment “protocol” below or check the link in my bio.
