To gain 1 pound a week, 500 calories added to your usual day would do it.
Add 500 calories per day to gain 1 pound per week.
3,600 calories (consumed in one day) will equal one pound of weight gained.
If you consume 3,500 calories then yeah
If you calculate your BMR this will tell you how many calories your body needs a day to maintain its weight. If you then consume 500 extra calories a day for a full week you should gain around a pound in weight. So I would say the answer is 3500 calories.
500 additional calories a day more than your RMR calorie burn to gain 1 lb a week.
How many calories does a 110 pound woman need a day to maintain her weight? Like 1500 calories..
Between 1000 and 1500 calories a day
How many unused calories is what's important here. Remember that you're burning calories just sitting around- about 80 an hour or so. You burn at least 1000 calories in a day just breathing, thinking and so on. A pound of fat contains roughly 4082 calories. So you'd have to consume 4082 calories beyond what you burn in a day to gain a pound of fat. Conversely, you'd need to burn 4082 calories more than you consume to lose a pound of fat. That may seem like a lot, but realize that an extra hundred calories a day, everyday, over the course of a lifetime can really add up, a pound a month, 12 pounds a year. A pound is equivalant to 453.592 grams, and 1 gram of fat is equal to 9 calories. Therefore 453.592 grams per pound*9 calories per gram of fat= 4082.328 calories per pound. But in all reality all of those calories wouldn't be stored as fat. They could be stored as protein or carbohydrates, which both contain 4 calories per gram, so plug in four instead and you get 1814.368 calories per pound. So calories needed to gain a pound are 1814.368 to 4082.328 calories.
In general, to gain 1 lb of body fat you need to create a calorie surplus of 3500 Calories. For example, if you intake 2500 calories a day and expend 2000, that's a surplus of 500 calories a day. At that rate you will gain 1 pound a week (7 days x 500calories/day = 3500 Calories) You need to consider your natural body metabolism and how much you exercise, and compare that to how much you eat.
400 calories
around a pound a week 3500 calories equals a pound of body weight
One pound = 3500 calories. Decreasing calories by 500 per day for a week = 3500 calories lost or 1 pound.
