Restricting calories: Below base metabolic rate (wt in pounds x 10) triggers starvation mode for the body causing you to overeat when food is available. You may lose a little weight at first but then the body will try to store fat to fight starvation. You'll gain it back and it will be harder to lose. Best to work with a nutritionist/health coach on a life plan for steady healthy sustained weight management.

3500 calories is 1lb: Pounds are lost by losing 3500 calories. So in a day if you eat 800 calories and your body burns 1800 calories through exercise and basal metabolism, you lose 1000 calories a day. Takes 3.5 days to lose 1 pound. So it depends on the calories your body burns. Varies by metabolism and exercise. You would lose 4lbs in 2 weeks. This does not include water weight loss.

Depends: 200 calories is a very small amount of intake but you can only estimate the loss of weight when you compute into the determination how much weight you have, how much exercise you undertake and whether you are basically healthy or not. Probably best to work with a dietician and your doctor if you restrict calories to this level.
