You probably can't eat enough to gain weight with just a couple of days of overeating, but according to the website SFGate, any extra calories you consume end up stored as fat, which means if you continue to regularly overeat, it'll make it easier for you to gain weight in the long run.
Don't try to make up for the extra calories by skipping meals the next day. That just leaves you hungry. Instead, cut back throughout the day with a series of small meals packed with fruits and vegetables. Their fiber will help you feel full, says Joan Salge Blake, RD, clinical associate professor at Boston University.
What you eat -- or overeat -- does not instantly turn into weight gain. How much you eat over the course of a few days or week, however, can result in weight gain.
A 2012 study at Oxford University found that the fat in your food ends up on your waistline in less than four hours. Carbohydrate and protein take a little longer, because they need to be converted into fat in the liver first and it takes nine calories of protein or carbohydrate to make 1g of fat.
The bottom line is that a 1000-1500 surplus of calories for a day means you'll only gain about 0.70-112 grams of fat. The scales might say you've gained more, but that's because of the water weight excess sodium and carbohydrates bring along with it.
It can be useful to remember that, just as one day of dieting will not cause a person to lose weight, a day of binge eating will not cause weight gain. Although an episode of overeating can happen to anyone occasionally, some people have a binge eating disorder, which usually requires professional attention.
Binge eating is when a person eats a much larger amount of food in a shorter period of time than he or she normally would. During binge eating, the person also feels a loss of control. A binge eater often: Eats 5,000–15,000 calories in one sitting.
First things first: It's totally normal for your weight to fluctuate 1-2kg in a day.
Even if you really overeat from your normal intake, it would likely be in the range of 1,000-2,000 excess calories per day. So for a 3-day weekend, that would be a total body fat gain for the weekend of only 1-2 pounds.
FACT: Research has shown that vomiting cannot get rid of all the calories ingested, even when done immediately after eating. A vomit can only remove up to about half of the calories eaten - which means that, realistically, between half to two thirds of what is eaten is absorbed by the body.
Why do so many of us get so fat? the answer appears obvious. “The fundamental cause of obesity and overweight,” the World Health Organization says, “is an energy imbalance between calories consumed and calories expended.” Put simply, we either eat too much or are too sedentary, or both.
A binge eating episode can last over an hour, though it may be much shorter or longer. Sometimes binge eating is a planned activity and other times it is not. Most binges involve the consumption of more than 1,000 calories, with a quarter of binges exceeding 2,000 calories.
Do not fast. Fasting after binging raises the risk of triggering a binging-fasting cycle. Fasting can make you more hungry so that you subsequently overeat.
Transitioning from a very low calorie and low carbohydrate diet to a low calorie and moderate carbohydrate diet often leads to a weight gain of 1-2 kgs in a matter of one day. This is mainly because of a sudden increase in the carbohydrate content which is stored along with water in the body.
Poor sleep, sedentary activities, and eating too many processed or sugary foods are just some of the habits that may increase your risk of weight gain. Yet, a few simple steps — such as mindful eating, exercise, and focusing on whole foods — can help you reach your weight loss goals and improve your overall health.
Don't try to undereat the entire surplus in one day by creating a deficit as large as the surplus because that will most likely lead to another binge in a few days. If your surplus was too big, simply get back on your diet and just think of it has your diet having extended just one week.
We will not gain 3kg in a day but it is normal for our body's weight to fluctuate by 2-3kg. Although our weight is one of the indicators of weight loss, however, it is just one of it, because our body weight is the combination of different parts which including: fat, bones, water, muscle, food and etc.
Bloating, gut health issues and hormonal changes can make you hold onto more water weight. The water weight usually settles down after your period. If you are not regular, or your fiber intake has been inconsistent, this can be a reason why you gained weight overnight.
There are many reasons you can gain weight that have nothing to do with food. Sometimes weight gain is easy to figure out. If you've changed your eating habits, added more dessert or processed foods, or have been spending more time on the couch than usual, you can typically blame those reasons if you gain a few pounds.
Don't restrict your food the next day.
Your first inclination is likely to cut WAY back on your food for the next few days. This only reinforces the binge/restrict mentality. You are better off eating healthfully and maybe a BIT lighter than usual if you wish as your probably won't be as hungry.
In fact, it doesn't happen that way. Depending on the number of calories needed for weight maintenance, a person would have to down a total of 5,000 to 7,000 calories in a day to gain any weight at all, and it's not likely to be even close to a pound.
You don't absorb every calorie you eat.
Some foods, particularly those high in fiber, make their way through the digestive system without being completely broken down. Others, some of the higher fiber foods (specifically those in the soluble variety), can prevent absorption of fat. Whole almonds are a good example.
