Like OytheGreat, I don't like to rain on your parade, but I have to agree with everything she said.
Crash/fad diets are not something sustainable - meaning you can't keep it up indefinitely; therefore, they are never a good idea. Don't get me wrong - I like Special K, but would not depend on it as my "path to thinness". It's true that most people who undertake such "diets", ultimately gain back all the weight they lost, and some gain back MORE than they lost.
You need to pick a diet and exercise plan that you can stick with over the years.
For a person who is 5'8" and 190 lbs, 1075 calories is basically starvation; I'm only 5' tall, but even when I weighed only 110 pounds, I couldn't sustain a 1000 calorie/day diet. Your body requires a certain number of calories/day, just to function; if you don't provide those calories, you will make yourself ill, and it's not necessarily the kind of ill that you feel right now; it's the kind of ill that creeps up on you, over the years. You must also provide you body with a good balance of nutrients. Trust me, I've been down that road.
I tried something similar to this, only I was eating 1100 calories instead. On day 4, I was so weak I could hardly climb a flight of stairs, which is not normal for me.
Losing more than 2 lbs a week isn't safe. Eating 1075 calories a day isn't safe either. In fact, drastic calorie restriction has the potential to lead to some very serious health issues.
I don't like raining on your parade, but every time I see a Special K challenge ad or any advertisement promising more than 2 lbs a week of weight loss, I chalk it up to false advertising. Any diet plan/pill/supplement/exercise program that starts off by promising so much loses all credibility with me. You can lose more than 2 lbs of weight a week, but it won't be fat that you're losing.
However, if you're careful, you can turn this into something positive, a good jump start into healthy eating.
My advice would be to gradually increase your calorie intake, but add the good stuff: lean protein, whole wheat, vegetables, fruit. Try researching the glycemic index. Low glycemic index foods seem to be universally beneficial when it comes to weight loss.
And if you haven't already, you can add some light exercise, like walking, as well as some light strength-training.
Since eating well will always be a way of life, not merely 2 weeks of dieting, you'll have to adapt some healthy habits beyond 14 days in order to maintain the loss.
Sorry if I'm coming off too harsh. I've spent most of my adult life battling obesity. I've talked to doctors, nutritionists, and have tried just about everything there is to try. I've also been involved in 6 years of team weight loss challenges. So far, there's a 100% failure rate amongst those who start off by sharply restricting their calorie intake.
Weight loss is a bit like the tortoise and the hare story, a slow steady march to the finish is what will win the day. :)
