Will eating 1000 calories a day cause weight loss?

Answer 1

Unless you are a kitten, eating less than 1200 calories a day will quickly make you so fatigued that you will be completely unable to exercise. For most people, you can eat something more like 1600-2,500 (subtract 500 calories from the total amount of calories required for you to maintain your weight) calories a day, and get an hour of cardiovascular exercise, and lose a healthy amount of weight. If you are going to do any serious weight lifting, like the sort that will burn more calories than cardio (moderate level weight lifting does increase base metabolism for 48 hours as opposed to 1-3 hours for cardio), then you will probably need something like 3,000 to 5,000 calories a day just to feel physically capable of completing your workouts. My advice, and I think anyone's advice here would be that if you want to do both you should do half an hour of intense cardio and follow it up with 30 minutes of solid weight lifting (clean and press, bench, squats, rows, deadlifts, overhead press 5X5 or something similar) and eat the amount of calories that you would need to eat to maintain your weight if you were NOT getting exercise. Then just pop a 5 hour energy or other stimulant before you hit the gym, and do your workout before sleep, after your last meal of the day. If you have insurance, go see your doctor. Not only can they check out your heart etc. before you get too serious, they can advise you how to safely lose weight fast. G'luck brah.

Answer 2

yes, BUT you will not lose pure FAT, which should be the goal of weight loss. The weight you lose will also include water, muscles, even organ tissue. If you consume too few calories (1,000 might be too few, especially if you are male), your body will actually stop burning fat, and you won't lose ANY fat. The end result will be that you will weigh less, but your body fat % will be higherand you will LOOK fatter.

Answer 3

That depends completely on your BMI (Body Mass Index) and your BMR (Basal Metabolic Rate). Your BMI is how much body fat you have in relation to your height and weight. You can check that here: http://www.myoptumhealth.com/portal/ManageMyHealth/BMI+Calculator
You're BMR is how many calories your body burns simply by existing (heartbeat, breathing, etc.) You can check that here: http://health.discovery.com/tools/calculators/basal/basal.html
However, you have to add to this number how many calories you burned going about your daily routine (highly depends on your lifestyle) plus however many calories your burned doing any extra exercise. It's considered EXTREMELY dangerous to eat anything under your basal metabolic rate which, unless you're two feet tall and weight 50 lbs., is definitely higher than 1, 000 calories. Plus, you have to factor in any other movement/exercise you get. If you are getting 1,000 calories a day, you are STARVING YOURSELF. While technically you will lose weight from this at first, it will in the long run cause you to gain more weight. Do you know why? Whenever an organism begins to starve, its body triggers a "survival mode". Basically, you're body slows its metabolism down to a grinding halt and converts any energy it takes in into fat. I promise you, you will inevitably succumb to hunger and binge. While the binge itself might not even be that big, your body will immediately convert it all to fat. If you really want to lose weight, make sure you get cardio exercise and build lean muscle mass. Believe it or not, having muscle actually helps you lose weight. The more muscle you have, the higher your metabolism. And please, don't starve yourself. I don't know anything about you height or weight wise, but I'd recommend getting at least 1,800-2,000 calories a day, probably more.

Answer 4

Given that most people require 1500 to 1800 calories a day minimum, you should lose weight.
