How much weight can you lose by not eating for 3 days?

Answer 1

I tried doing that but i kept wanting to eat. I'm guessing you could lose under a pound, maybe 3000 calories. Not much.. But not eating could become a habit and you could go into starvation mode where you lose a lot of muscle. After you fast, you could gain even more fat then you had before.

Answer 2

Unfortunately, it's not as much as you would think. As soon as your body detects starvation it starts to shut down unnecessary activity, metabolism slows and you will start to rob muscle mass for necessary nutrients. As muscles start to diminish, you'll burn fewer calories and your weight loss program will not be as effective as you hoped. Instead, do maximize weight loss and to KEEP it off and do it in a healthy way, try feeding yourself properly and exercise to burn calories. Remove fat intake from your diet. You can loose weight safely for a couple weeks without ANY fat calories. Recognize that fats are very high density calories. One gram of fat is 9 calories, so cutting out fat helps a lot. Fats hide in all kinds of sneaky places. Cheese is bad for your diet, as is fried food and butter. Instead, eat a low calorie diet, with plenty of fish and other proteins. Red meats (beef, pork, lamb and any other mammal meat) should be trimmed of fat before you GRILL it (don't fry ANYTHING), and chicken should have the skin removed and fat trimmed. Avoid hamburger, since most butcher shops put a LOT of fat in the hamburger as they grind it. Eat some fruit regularly, but avoid avocado and anything else with oils. While potatos aren't a source of fat or calories, they are almost impossible (at least for me) to eat without butter, sour cream or SOMETHING made with a lot of fat. For a couple weeks, count every fat gram and weigh everything you eat. Eat smart and limit your fat grams to less than 20 grams per day, and save them for fish, fowl and trimmed red meat. Read labels and don't eat anything with sugar in the first 3 ingredients. Write down everything you eat and eat plenty of raw fruits and veggies. After you've done all of that, you're half way there. You also need to exercise, a lot. But that diet will help you since you'll have the protein to keep your muscles healthy. The exercise will cause you to burn far more calories and you'll LOOK good when you're done. Remember that it took a long time for you to put those calories on, and any attempt to take them off too quickly could turn out to be unhealthy.

Answer 3

While a person not eating for ten days could lose anywhere from 10-30lbs / 5-15kg, this is also very dangerous. Also, as soon as any food is eaten the body will regain much of the weight since a lot of weight will only be lost through fluids and excretion, not entirely physical weight loss.

Answer 4

How much weight you will lose after 3 days without food depends upon various factors. Such factors include your current weight, gender, age and metabolism. You could lose an average 3 to 5 pounds, maybe even more.

Answer 5

That would depend. Weight, always remember this, is a balance between energy gain and energy loss. Energy gain naturally comes from the calories we eat, for a 70kg adult that would usually be around 2000 calories/day. Energy loss mainly would be from basal metabolism (the energy that your body needs to maintain itself), thermal action of food (energy you use to digest the food you eat) and finally physical activity.

To net weight loss, you must either 1) decrease energy gain to less than your total caloric requirement or 2) increase energy loss by increasing BMR by bulking muscle, or more easily by exercising

To answer you question, if you fast for 3 days eating absolutely nothing, that would net you an energy loss of ~ 6000 calories. A pound of body fat is worth ~3500 calories, so for all your effort you only lose the equivalent of less than 2 pounds of body fat. The weight loss i mentioned does not account the weight from water loss if you also decide not to drink.

Answer 6

I did it... I was 5'11 and 230... I lost 11 pounds

Answer 7

If you weigh 110 you dont need to lose any weight!!!! Any weight you do lose will go straight back on the moment you start eating again.

Answer 8

Depending, but around 1-3lbs

When you start eating normally again, you'll gain all this weight back.

Do. Not. Stop. Eating.

Eat healthier.

Answer 9

I hope you are not planning on doing this. It is EXTREMELY UNHEALTHY to do so if you have access to food.
