First of all no human should ever subject themselves to that kind of diet. That is a boderline anorexia. The amount of calorie intake should be nothing less than 1200. But to answer your question, it depends on how much energy you exert that day. Your body runs off calories like a car runs off gas. If you don't exercise or sit on the couch all day you aren't going to burn anything that you eat. I would suggest talking to your doctor, depending on your current size, weight, age and current eating habits it will be easier to make an exercise program that will work for you without putting an extreme amount of pressure on the body.
This would depend on how many calories you consume over that same time period, what type of calories you are eating (fat, protein, carbs) and where the calories you are burning are coming from (fat stores, glycogen stores, muscle, etc.).A very basic and oversimplified example to make this point would be if you burn 1020 calories per day for 30 days, but you eat 1020 calories per day for the same 30 days, you would not likely lose any weight.A second example to make the point, if you burn 1020 calories per day for 30 days, but you eat 2000 calories per day, you will likely be gaining weight.Thus, to lose weight you must be eating less calories than you are burning each day.
you would die if you ate that many calories. to lose weigh find out how many calories you should be eating for your current weight and then find out how many calories you should be eating for your target weight. slowly inch your calories down to that target weight range. and really you should ask your doctor about weight loss. to see if you even need it.
If you are planning to lose weight, burning more calories than you take in is one of the steps to get you there.If you need to gain weight instead, taking in more calories than you burn would be advisable.If you want to maintain your current weight, taking in and burning about the same number of calories would be a step in the right direction.However, in all of the above scenarios, the number of calories is just one aspect of the effort. The quality of the calories you take in and the quality of the physical activity that helps you burn calories also play important roles.
A weighted vest might help you lose a bit more weight. That is because you would be burning more calories by carrying the weight around, and also building more muscle. Muscle burns more calories than fat.
You might gain weight, but eating that many crisps would be very unhealthy. It would be much better to eat a healthy, balanced diet that included more calories than normal.
If a person is burning more calories actually what he/she consumed, this situation leads to get weight loss of that particular person.
Eating 800 calories a day is very dangerous. A man of that height and weight should be consuming about 2,000 to 2,200 calories a day. If they wished to lose weight, the best way would be to reduce the calories to around 1,600 to 1,800 calories a day and begin to exercise. Such a dramatic cut in calories (to 800, for example), would reall begin to wreak havoc on the metabolism and not lead to healthy, long-term weight loss.
most people would loose weight because instead of eating before bed and not working of the calories it would lead to weight gain (ex. sugar turns to fat if not burned off) so not eating after 6 would help you loose weight in that sense, but it all depends on the persons body type or your lifestyle.
It is said that 3,500 calories is equal to one pound. This means that if a person consumes 144 calories, they would only lose 1/8 of an ounce or so, if that. Eating 144 calories is not likely to make a large difference at one time in weight.
You would collapse and gain more weight and when you do start eating u would double to amount of fat and calories in the food
Foods do not burn fat. Fat is calories and calories come from food. If you want to lose weight, determine how many calories you must take in each day to maintain your current weight. Once you have that figure, calculate how many calories you can subtract from that amount and still maintain proper nutrition. Let's say you need 2200 calories to maintain your current weight. If you implement an eating plan of 1700 calories per day, you'll have a 500 calorie per day deficit. Over the course of 7 days, you would lose one pound. If you stop up your physical activity, you'll burn even more calories and lose more weight. Eat healthy and make good food choices to support your plan. There are no "fat burning" foods, however. www.nutrition.gov
If you eat 500 calories a day, or less, you may be condsidered anorexic. That is completely un-healthy and even if you were to lose weight, you would instantly gain it back once you ate regular again...and you would have to eventually eat regular again if you want to live, because eating 500 calories or less is starving yourself to death.
