For those who were deceived by this theory when they were young, they said, "We should lose weight through the valley." For seven days, they only drank Nongfu Spring. From the third day on, they suffered from persistent stomachache, insomnia all night and depression. I did lose more than ten kilograms after the end, but I ate it back in two weeks. Sequelae emerge one after another, and the most depressing ones are insulin resistance and a series of health problems. If you don't understand insulin resistance, you can Baidu it. As for the weight, it has skyrocketed by dozens of pounds in a few years. How painful! Now, if someone tells me to get out of the valley, my first reaction is to slap my ears!
