no exercise no weight loss?

If you keep the same calorie deficit by eating less and not doing as much exercise, you'll still lose weight. I've been recovering from a leg injury for the last ten days and I just adjusted my meals to have the same calorie deficit, still seeing the same results as when I was exercising 6 days/week.

Diet is the big thing with weight loss, but I have to say that 1000 calories a day is way to little for a 19 year old. I ran the numbers with a guess at your weight from your ticker, even at only 4 feet tall you should be eating at least 1300 calories or so for a reasonable deficit. That is being completely sedentary. Likely you are not completely sedentary since you do some activity on the exercise bike, and from what I remember of school (college) there is a fair amount of walking to simply get around campus. Likely you are lightly active, and likely you are taller than 4 feet tall which would increase your calorie need. Look here for more information and to figure out your numbers based on your real height and weight. http://www.myfitnesspal.com/topics/show/654536-in-place-of-a-road-map-2-0-revised-7-2-12

I (generally) eat between 1200-1300cals a day and I have lost 7kg in about 3 month with no exercise. I don't *necessarily* recommend it, because exercise is obviously very good for health and muscle definition, but I just hate it. I'd much rather restrict myself than have to go jogging everyday. 1200 is actually quite a lot of food if you're clever. I also don't log any exercise that I actually do, because I think it's better to have consistent diet if you expect intermittent exercise to work. You ought to increase your calorie intake to at least 1200, or you may go into "starvation mode" or something similar.

It depends on your numbers. I am 68 years old and weigh 130 lbs. I put my lifestyle as sedentary which it is unless I make a point of going out to exercise. Based on this information MFP says I use 1360 calories a day. I take in 1,200. With a daily deficit of only 160 calories my anticipated weight loss is less than half a pound a week. I am not that patient. I wear a fitbit and I try to burn an average of 400 calories a day in exercise. This allows me to lose about a pound a week and still eat a balanced diet.

i read here http://greatist.com/health/exercise-weight-loss-8-31-12/ that Exercise Doesn’t Always Lead to Weight Loss... but confused??

Weight loss occurs whenever you burn more calories than you take in. If you can exercise enough to burn more calories and would rather do that than cut calories, then exercise is the way to go. If, however, you're more willing to trim your portions than go out running, dieting will work better.

I've lost 140 lbs in the last 11 months by counting calories with MFP phone app. I did this without exercise.

I eat around 1000 calories a day and half the week exercise lightly and half I sit around working all day, bloody essay deadline period! I usually use the exercise bike daily when I go home but stick to skipping for 15minutes a few times a week.

Does weight loss really depend on both exercise and diet?
I'm so busy with work lately I just don't have the time to make for exercise a lot and I'm worried I'll come to a standstill!

Not at all. One can reduce their body fat and body weight by simply eating at a caloric deficit (eating below your TEE (total energy expenditure). Although I do recommend you try and do a bit more cardio as it's beneficial to your overall health.

I eat around 1600 a day and rarely exercise and I'm losing just fine :flowerforyou:

I intially lost weight without exercise but it is still very important for health.

And as i'm sure you know, 1000 calories is no where near enough. You may lose weight now, but what do you expect to happen years from now when your eating more? Even a small amount like 1500 would make you gain weight very quickly because you ate so low for too long. Excuses that it's hard to reach 1000 just don't cut it. I'm sure you have time to fit in some small snack more often or add more fat like nut butters and oils to increase your calories intake. If your not at a stand still with 1000 now, you will be eventually.

I know it wasn't your question but if your going to post that info on a public form then I feel I should at least say something about it coming from an eating disorder past... There are a lot of food options that are healthy and will significantly increase your calories without making you uncomfortable if your problem really is just not being about to reach a good amount.
