Gaining weight in a short period of time may be required for sports like wrestling, or it might be desirable to recover from a fast. Whatever the case, it's possible to gain a significant amount of fat in the course of a week. For most people, gaining weight quickly requires a dramatic change in lifestyle and it will be an around-the-clock effort, but for those who enjoy food and relaxation, the experience can be an enjoyable one. According to nutritionist Alison Dempsey, the amount of fat that one can gain in the course of a week varies dramatically based on factors like the individual's metabolic rate at the beginning of the week (the faster the person's metabolic rate, the longer it will take to slow it) and how much food the individual can consume. For an individual who goes into this week of weight gain with a slow metabolism and a body that's accustomed to eating large meals, Dempsey says it's possible to gain one pound per day or more.
Take weight gain supplements daily. The precise dosage and frequency will vary depending upon the specific product. These supplements contain calories and vitamins to promote the development of fat and muscle. They are different from the protein supplements that are typically used to gain muscle mass, though weight gain supplements often contain protein as one of the ingredients. Examples of these weight gain supplements include Weider's Dynamic Weight Gainer and Twinlabs Gainers Fuel.
Eat a meal every eight hours. The meals should be high in carbohydrates like bread and pasta, fats like dairy foods, and high in protein, which is found in meat and eggs. Eat as much as is physically possible during each meal.
Drink beer or wine with each meal. Beer and wine is high in calories and alcohol slows the central nervous system, thereby slowing the metabolism and allowing for more weight gain.
Drink a glass of water with each meal to prevent dehydration from the alcohol.
Sleep for four hours immediately following each meal. Sleeping slows the body's systems, so the food moves through your body at a slower rate. This means the food is in the digestive tract for a longer period of time, allowing for the absorption of more calories, fat and nutrients.
Drink a high-protein shake and eat a high calorie snack (like an energy bar, potato chips or ice cream) immediately after waking from the four hour nap.
Relax or sleep until the next meal and repeat steps two through five. It's vital that you avoid any sort of physical activity or exercise, as this will cause the loss of calories and fat.
Smoke cigarettes to trigger an increase in the production of cortisol, a stress-related hormone that is also activated by alcohol consumption and a lack of sleep. Cortisol causes the body to gain weight--fat, in particular.
Watch scary or suspenseful movies or television shows while relaxing. This causes the body to experience stress, triggering the production of the hormone cortisol.
Avoid eating low fat foods, vegetables and fruits. This will take up space in your diet that you could use to consume high calorie fats and sugars.
Rapid weight gain is unlikely to be permanent. Long-term weight gain is best achieved by forming new habits and lifestyle changes that are consistent with weight gain. Healthy weight gain involves gaining fat and muscle over a long period of time.
