It's better for your body to gain weight slowly than to put on weight quickly. Eating a surplus of 500 calories a day more than you burn results in a new pound of body mass per week. General rules include eating more often (five to six times per day), eat more fat and eat more protein.
Following a very low-calorie diet (500 calories) for more than a week makes your body weak and lowers your immunity and productivity. Hence, it is important to consult your doctor and dietitian before following a VLCD for a long time.
A 500-calorie diet may be beneficial in the very short-term for people with obesity, or as a pre-operative measure. However, people just looking to lose weight should try making sustainable diet and lifestyle changes, such as increasing their vegetable intake in all meals.
Eating 3500 calories every day can help you gain weight, only if you maintain a calorie surplus. Again, you will add some pounds to such a diet if you consume more calories than you are burning. It means that you have to burn calories that are less than 3500.
To gain a pound of fat you would have to eat 4000 more calories than you burn, so probably like 5500 to 6000 calories. You should be eating more than 1155 every day if you're interested in surviving.
The average recommended daily caloric intake for an adult is around 2000-2500 calories per day, and consuming only 500 calories per day for an extended period of time can lead to severe malnutrition, weakness, and other health problems.
The direct (and text book) answer is that if you eat 500 extra calories in a day, that days caloric excess will result in a weight gain of 2.3 ounces. 1 lb. of fat will be lost or gained depending on whether 3,500 calories are consumed in excess, or, restricted from caloric homeostasis.
Generally speaking, every 1kg of weight gain needs about 7000 additional calories [or 29 300 kilojoules].
If you can eat 500 fewer calories every day, you should lose about a pound (450 g) a week. Always talk with your health care provider to determine a healthy weight for you before starting a weight-loss diet.

Restricting your diet to 500 calories a day is not recommended unless you are following a medically-supervised program. And while you may be able to follow a very low-calorie diet (VLCD) for a short time, this is not the type of plan you should attempt without medical supervision.
To lose about 0.5kg a week, you would need to consume 500 calories below your daily calorie requirements. To lose 0.25kg a week, you would need to consume 250 calories below your daily calorie requirements.
You will suffer malnutrition and disease, perhaps be at risk of sudden death. Extended starvation, which a 600-calorie diet is, is serious. I'm sure you've heard of the RDA, the recommended daily allowance of all the nutrients I mentioned that the medical professionals believe is absolutely necessary to stay healthy.
Even if the scale goes up, you know that it's nearly impossible to gain multiple pounds of fat overnight. It's the sodium, carbs, and water that cause the bloat and additional gain in water weight (which will come off over time). One feast, therefore, isn't the big problem that causes holiday weight gain.
A Fast Metabolism
This rate changes from person to person based on a number of factors, including genetics, diet, and level of activity; if you eat a lot but don't gain weight, it could be because your BMR is high, so you burn calories at a greater rate than most people.
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.
However, other studies show that while consuming 1,000 calories a day may result in significant weight loss, most people cannot sustain it and often experience significant weight regain . The reasons include regaining lost muscle mass and increased appetite. Also worth noting is that the human body can adapt.
If you only eat 600 calories a day, you are in a deficit of 1,500 calories. There are 3,500 calories in a pound, so you would lose a pound every two to three days. While your 600 calories a day weight loss would start strong, keep in mind that it will slow down over time as your body adjusts.
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.
