Make sure after a day of larger eating, you get back on the bandwagon! The issues come when we maintain an eating schedule like this for weeks and months on end; that's when problems start. 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.
First things first: It's totally normal for your weight to fluctuate 1-2kg in a day. Ever so often, patients come to me, saying: “I've tried several strict diet programmes and yet things go wrong. After all the hard work and effort I put in with diet and exercise, my weight doesn't budge.
A person can't actually gain or lose multiple pounds of body fat or muscle in a day, but it is possible to retain or shed a few pounds of liquid. Diet — especially salt consumption — plays a major role in how much water our bodies hold onto throughout the day.
Healthy weight gain of 1-2 pounds per week can be expected when reasonably increasing energy intake. It takes an excess of about 2,000 to 2,500 calories per week to support the gain of a pound of lean muscle and about 3,500 calories per week to gain a pound of fat.
In order to gain a pound of fat, you would need to add about 500 calories a day on top of your normal diet, every day, for about 7 days. This makes gaining any significant amount of fat from even the craziest all-out cheat days extremely unlikely.
This energy reserve is pack with 1.5 to 2 kg of water. So when your glycogen stores shrink when you do not consume carbohydrates, so does your water, and thus it's normal to experience glycogen and water weight shifts of up to 1 kg per day even with no changes in your calorie intake or activity level.
Theoretically, eating 10,000 calories in a single day can make you gain up to 3 pounds (1.5 kilograms) of weight. That's quite a lot, and depending on your age, height, weight, etc., you'd need around 10 hours of intense exercise to burn it off.
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.
Putting on one kilogram overnight is pretty much impossible. So breathe Mama, and let me explain more below. For you to ACTUALLY put on 1 kilogram overnight you would have to eat 7,700 calories over your daily allowance in 24 hours.

To put it bluntly: "Women and men of average height need to gain or lose about about 8 and 9 pounds, respectively, for anyone to see it in their face, but they need to lose about twice as much for anyone to find them more attractive," lead author Nicholas Rule told Medical News Today.
If it's only a day of eating 4000 calories, then you continue eating like you normally do (within normal capacity) then it's unlikely you'll notice any weight gain.
Why does my weight fluctuate so much? “Everyone's weight fluctuates throughout the day, and especially from morning to night,” says dietitian Anne Danahy, MS, RDN. “The average change is 2 to 5 pounds, and it's due to fluid shifts throughout the day.”
Since you're not eating or drinking during the night (unless you get the midnight munchies), your body has a chance to remove extra fluids (that's why you pee so much in the morning when you wake up). So weigh yourself in the morning ... after you pee.
The good news is that you can't just gain 3kg of fat in 3 days. There are plenty of ways that your weight can fluctuate that aren't to do with your fat mass. Here are a few of the most common causes of sudden weight gain.
You don't absorb every calorie you eat.
On average, roughly 95% of the calories you put in your mouth are absorbed during the digestive process. However, as you may have noticed the last time you took a number two, not every parcel you eat is entirely digested.
Nope… Your body can't digest this many calories in one go.
A gram of fat (like oil) has 9 calories. In order to eat 100,000 calories you would have to guzzle down over 11 liters (or nearly 3 gallons) of pure oil. It is physically impossible to eat 100,000 calories in one day.
He explained that "muscle is more dense than fat, so an identical volume of it will weigh more than fat." Exercise physiologist Krissi Williford, MS, CPT, of Xcite Fitness, agreed and said even though your muscle mass weighs more than your fat, "it takes up less space, which is why you look leaner and more toned."
You'll notice almost right away by looking in the mirror. Most people who start losing weight can lose 2–4 kilograms in the first week. You will notice this by looking in the mirror. However, most of that weight is water lost and if you don't keep up with the diet you'll gain it back just as quickly.
When you have a slow metabolism, your body doesn't convert food into energy in sufficient quantities. So most of the food you eat is stored in the form of fats. This is the main reason why some people get fat even though they don't eat much.
Takeaways. Binge eating may contribute to temporary weight gain if you eat high sodium foods, or foods rich in carbohydrates. It is unlikely that a single binge will contribute to permanent changes in your weight. You can learn strategies to help decrease the chances of a binge.
Many people scoff at the notion that having just one cheat day per week will ruin their fat-loss efforts, but it absolutely can.
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.
You should step on the scale first thing in the morning. That's when you'll get your most accurate weight because your body has had the overnight hours to digest and process whatever you ate and drank the day before.
