Can I live on 800 calories a day?
Hard to tell. Mostly, I agree with the previous answers, but I am not absolutely sure. People on caloric restriction diets survive long term eating 1200 calories per day, but they usually work out somehow, so maybe if you didn't... There are also some people that insist they survive eating less than 600 calories per day (check BIGU on the Internet), but it is what THEY say they do. Moreover, there are some monks allegedly surviving on few calories, but it is hard to tell where legend stops and reality starts.
Is 800 calories a lot for a day?
No! A sedentary woman should eat a minimum of 1200 calories.
Is 800 calories a day too low?
Hey, that is indeed much too low. Cutting your calories this low is very bad for your health, and will be causing a lot of health problems which you won't realize until it is too late. In addition it also slows your metabolism so won't even be doing your weight loss any favors. I would recommend increasing your intake to at least 1400 calories a day. x
Can you die if you eat 700 calories a day for a week?
No.The human body is incredibly resilient when it comes to nutrition and survival." In 1965, an extremely obese 27-year-old male, weighing in at 456 pounds fasted for 382 days (one year and 17 days) and lost 275.5 pounds.Doctors from the University of Dundee monitored his condition throughout his fast. During his fast, he obese man recorded low glucose levels for 100 days and defecated every 40 to 50 days. He was given potassium tablets to keep his heart healthy and multi-vitamins every day."-Thought CatalogBasically, if you have any reasonable amount of body fat on you, you'll be able to last quite a while without food.There's also several cases of people eating diets consisting of 1200cals or less who end up living to be 90–100+ years old.You do, however, need water to survive. Go even a few days without it and you're done for.
How long can you survive on 500 calories a day?
You wouldn't be able to survive forever on that type of diet; your health would slowly deteriorate. You would lose weight to the point of amenorrhea (loss of your period) and infertility. You would eventually die of malnutrition or maybe heart failure. This would probably happen over a course of years. This is basically what happens to people with anorexia nervosa.
Eating 800 calories a day?
That's almost exactly what I did for three or four months. Kept my calories generally under 1000. Breakfast was one fried egg and one slice of toast every day. Lunch was usually a bowl of soup or a plate of vegetables. Dinner was often a serving of cottage cheese or a small piece of chicken with vegetables. I imagined eating as if I had gotten that bariatric surgery and could only take very small bites and eat very small meals. I lost a lot of weight very quickly. One key, I think, is that I did exercise every day. That helps keep your metabolism up, and helps you keep muscle. How much you lose depends a lot on how much you weigh to start with. Since I started out at about 250 lbs, I lost almost 30 lbs in the first month. Out of the total of 80lbs that I lost, 70lbs was fat. The rest was some combination of muscle and maybe water. (Again, I did strength training three times per week for that whole time). That's a very good result. Better than most diets. The diet was very effective. Eating something a bit more on a Saturday helped keep me from going insane. I don't know if I believe in "starvation mode", but it still seems like a good idea to relax a bit and enjoy whatever you crave every now and then. If you stick to a healthy normal diet after the weight loss, you shouldn't have a problem with regaining the weight. It's only when your habits slip. However badly your habits slip is how quickly you would regain the weight. You might be surprised at how unhealthy the average person's lifestyle is. If you eat like everybody else, you'll gain weight. You kind of have to become a health nut for life. The only other thing I'd care to mention is that I felt hungry a lot on that diet. And sometimes I even felt dizzy when standing. But I would just focus on how much I hated being fat and all the ways it impacted my life and use all that negative energy to force myself to stick with it. Once I started seeing the weight drop off and feeling better, it got easier to stay motivated. I made a lot of small goals (lose at least a pound this week, get down under 200 -- my BMI for obese, get down under 180 -- my healthy friend's weight, get down under 170 -- my ideal weight). That way you are constantly accomplishing goals and that last one isn't so distant to discourage you. You can always focus on the things that are close.
Is it possible to live on 1000 calories a day?
It’s possible to live on any number of calories. The question is how well and for how long. Unless you are a tiny person in a coma, though, your BMR is almost assuredly more than 1000 calories. Eating less than your BMR is called starving to death. How quickly this diet kills you depends on a lot of factors, including your health and weight when you started, and how long you persist in trying to kill yourself.
If I burn 1,000 calories at the gym and eat 800 calories a day, how much will I lose in a week or month?
It takes 3500 cals to gain or lose 1 lb. There's not enough info on your life to find exactly how much you'll lose. It depends how active you are besides the gym. (Eg. walking to school/work, or just sitting at a desk job all day, working at an active job, etc) But an average adult woman, weighing 130 lbs, burns about 1600 calories each day while sedentary (very inactive life). So I wouldn't recommend only eating 800 cal/day. That's not enough to fuel your body. I'd go to minimum 1000 cals/day. You'll still see results, but it'll be a little easier on your body. If you go too low, you go into starvation mode and once you eat more than that when your diet is done your body will keep all the fat and extra calories incase you starve again. Likely undoing what you just lost, and gaining more. Don't forget your protein and carbs too, because eating so few calories and working out so much you may burn muscles instead of fat. Do some toning exercises so you don't lose your muscle. Skinny w/o shape isn't as sexy. Don't forget you're always burning calories, even when you sleep. (Btw, sleeping burns more than watching TV) Also, eat lots of food that just may happen to be low cal so it fills you up and you get your vitamins. Lots of fruits and veggies. Stay away from high sodium diet foods. Saying all that, if you live an inactive life (besides the gym that you're going to be going to) you can lose about a lb every 2 days. (It may be more at the start.) 1600 cals burned + 1000 at the gym = 2600 2600 - 800 = 1800 cals burned/day. 3500/1800 = 1.94 days to lose 1 lb. with 1000 cals eaten /day it only goes to 2.1 days/lb.
