Since most of us can't eat so much in a day or two that we actually gain a couple of kilos a day, a dramatic increase in weight could be due to water retention. Eating, drinking, urinating, bowel movements, exercise—everything can affect your body's water composition and, therefore, weight.

The Right Way to Weigh In
Use your scale every morning after you empty your bladder (and before you eat or drink anything), wearing as little clothing as possible. Because you lose water weight overnight, you'll get a lower number, too. Place your scale on a hard, even surface—no carpeting.
Bloating may occasionally add a pound or two, but it doesn't actually signify weight gain. A simple way to tell the difference between bloating and weight gain or fat is how your stomach looks and feels. If your stomach is tight and hard, then bloating is the cause. If your stomach is soft and thick, then that's fat.

Clothing. Wearing clothing while weighing yourself can add up to two pounds—more if you're wearing shoes.
