If you want to lose a small amount of weight quickly, you should do so effectively and safely, no matter your reason for wanting to shed pounds. However, you can safely shed weight from retained water and waste, and lose 5 lbs. (2.3 kg) or more within one day. Be aware, though, that this process cannot be safely repeated for more than one day (i.e. you cannot safely lose 15 pounds in three days), and the weight that you lose in one day is likely to return quickly. It is smart to maintain a healthy body weight, and weight loss should be combined with long-term lifestyle changes, like eating healthy and exercising.
Avoid going down grocery aisles that tempt you with high calorie foods. It’s best to stay along the perimeter of the grocery store, which is where the fresh foods are typically located. However, when you need to go down the aisles to get something, try to stay away from areas where foods you crave are stocked, such as the candy or soda aisle. If you don’t see them, you’re less likely to be tempted.
Second, take a few photos of yourself to keep your motivation up. "Most of the people who come to me are doing it for a reason," he explains. "They're going on vacation, competing in a bodybuilding show, or maybe going to a reunion. I always have them strive for that goal. I take front, side, and back pictures of them at the beginning and have them post the photos on their mirror at home. I tell them, just keep looking at that picture and think of what you're going to look like in a few weeks."
And maybe a new mattress, because it’s not just the amount of time you spend sleeping that keeps you lean, it’s also the quality of your sleep. Fat cells in your body produce a hormone called leptin that helps the body keep track of how much potential energy (i.e. fat) it has stored. But leptin is only produced during certain stages of sleep. Miss out on those stages because you’re not resting soundly enough, and you’ll disturb levels of the hormone, leaving your body with no real idea of its energy reserves. Consequently, you’ll end up storing calories rather than burning them.
