Updated 7 days ago. this guide will show you how to lose 10 pounds in 10 days very easily. i wrote this guide a while ago now and came back to it as i wanted to test it out again since we are all practicing social distancing and not getting as much exercise.. Drink a lot of water throughout the day. do you want to lose weight by drinking water? start by consuming a lot of water throughout the day. it will allow you to feel full without drinking other high-calorie and sugar-laden beverages such as soda and juice. drinking a lot of water will also help you stay away from unhealthy snacking urges.. Drink at least the recommended amount of 64 ounces of water a day. do not drink it all in one sitting, but instead have one cup of water at a time over the course of 9-10 water breaks. this is to replenish the water you lose throughout the day. drink more water if you can; 64 ounces is the minimum..
