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 balance between energy in (eating) and energy out (burning off those calories) is why your weight goes up and down. If you take in more than you burn, you gain weight -- sometimes right away.
The 2 kg that you gain right after a huge dinner is not fat. It's the actual weight of everything you've had to eat and drink. The added weight of the meal will be gone several hours later when you've finished digesting it.
Eating 3000 calories a day can lead to weight gain. This is because three thousand calories a day are more than an average individual needs in a day. However, some people like athletes actually do need around these many calories or even more. It is advisable to consult a professional before you start this meal plan.
Water retention
Eating, drinking, urinating, bowel movements, exercise—everything can affect your body's water composition and, therefore, weight. For example, high-carb and high-salt foods lead to water retention and an increase in weight.
If you get on the scale and see your number go up, it's simply because your blood volume level has increased due to the large quantity of food that you've eaten. The high sodium content in certain prepared foods also causes the body to retain fluid, thus causing a higher number on the scale.
Even studies suggest that it is difficult to gain weight after one day of overeating. Some people say that they gained 4-5 kilos after six-weeks of the holiday period, but as per a study published in the New England Journal of Medicine, on an average, most people gain just one kilo.
You May Be Retaining Water
While consuming too much salt or certain types of processed foods is the most common culprit of water retention, standing or sitting for too long, hormonal changes that occur around your menstrual cycle, and even certain types of medication can cause increased water retention.
How long does it take for your body to start absorbing calories? As we digest food, our body transports and utilizes various vitamins, minerals, protein, carbohydrates, and fats at different points along the digestive tract. The absorption process begins around 3-6 hours after eating.
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. And you should try to turn that step into a regular part of your routine.
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.
No. 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.

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.
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.
When you have a cheat day, chances are, you're eating over your BMR, which means if you keep this up, you'll start gaining weight. However, just one cheat day won't completely throw your diet off track and it doesn't necessarily mean you'll gain weight.
It depends on how much you weigh to start with, how active you are, and how much muscle you have. Generally speaking, if someone who is fairly lean and active gains 5-10 pounds of weight, it will be noticeable. If someone who is overweight or obese gains 10-20 pounds of weight, it will also be very noticeable.
Your metabolism increases whenever you eat, digest, and store food, a process called thermic effect of food. Protein has a higher thermic effect compared with fats and carbohydrates because it takes longer for your body to burn protein and absorb it.
