Don’t drink liquids when you eat. Drink significant quantities of water at least half hour before your meals, or at least an hour following meals. During mealtimes, try to drink as little as possible. Too much liquid with meals slows down digestion by diluting digestive juices, and inefficient digestion is a contributor to difficulty in losing weight.

Do some sober socializing. Drinks pack on the pounds: Pure alcohol contains about seven calories per gram, which makes it nearly twice as fattening as carbohydrates or protein (both contain about four calories per gram) and only just under the caloric value for fat (nine calories per gram). Your body processes alcohol first, before fat, protein, or carbohydrates, so drinking slows down the burning of fat. Cut back to one or two glasses of wine at a time and decide how many nights you can do that every week.
