Is it healthy to lose 3lbs in 1 day?

*** What does it mean "to only lose water weight"? — Confused on water or H20 This is a fantastic question because dieting is so common in today's society and we all hear about "losing water weight" and its connection with dieting and weight loss. So let's clear up our confusion. During the first few weeks of weight loss due to dieting, a rapid drop in pounds is normal according to the Mayo Clinic. When you reduce your caloric intake, your body gets its needed energy by releasing and utilizing its stores of glycogen, which is a type of carbohydrate found in the muscles and the liver. Glycogen holds onto water, so when glycogen is used and burned up for energy, it also releases the water it holds onto. This is about 4 grams for every gram of glycogen. This results in the initial "water weight" loss that accompanies early weight loss from dieting and calorie restriction.
