1200 calorie diet safe?

Hello everyone.

Has anyone tried really low calorie diets? What is your opinion on low calorie diets? Too extreme or still safe?
I mean, my basal metabolic rate (BMR) is way above 1800 calories and 1200 calories per day would be a 600 calories deficit. That is about 33% deficit.
I've heard that too extreme diets such as 1200 calorie diet is can harm your progress when losing weight because your body will switch to starvation mode - because of a sudden lack of energy. Is this true? Should I be doing a low calorie diet and now and then (after few days) I would eat a lot more than my BMR just to let my body know that it doesn't have to starve...
Also, what is in your opinion the most radical yet still healthy calorie deficit? 10 percent, 20 percent, 30 percent? I was thinking of trying a 1200 calorie diet but I have second thoughts... I do not want to slow down my metabolism or hinder my progress in any other way. And the least I want is that I would gain all the kilos right back after finishing the diet.
My plan is to lose 5 kilos of fat, which is about 45.000 calories (1 gram of fat is 9 kcal). If I would have a 600 calories deficit every day I could lose those 5 kilograms in about 75 days (2 months and a half). I will still be eating a lot of proteins as well as I don't want my muscle mass to go away along with that fat. I was thinking of following a 1200 calorie diet but remove some carbs and add some more proteins. If I divide 1200 calories into 5 meals per day, that would mean about 240 calories per meal. I will also drink a lot of water (2-3 litres per day).
What is your opinion?

This is a question that has two camps - yes and no. My answer - its fine. but, in your case, perhaps unnecessary if you dont have a lot to lose. your BMR serves as a good calorie guideline for weightloss. Jillian michaels did a whole book on losing the last 10 pounds and had you use you BMR as your daily calorie target. your BMR is what your body needs just to exist, it doesn't account for movement and exercise. So you wouldn't have just a 600 cal deficit, you'd have 600+ whatever exercise and movement contributed. It may result in faster weightloss, but maybe not sustainable in the long run.

Google Harris Benedict calculation. You take your BMR and multiply that by a number representing how active you are. That number indicates your calorie limit to maintain your current weight. I won't spell out how to do all the calculations but from there you can figure out about how much weight per week you'll lose based on how many calories you take

Why is 1200cal a magic number that everyone posts? I assume its based on some average person. Can you define average and are you the perfect average? Why not start with just reducing the number of calories you currently consume by about 100? Exercise and use that target for a week. If you start to lose, fine. If not, then drop another 100 and try it for a week until you find the correct cal count necessary for healthy wt loss. Everyones proper cal count for healthy wt loss is going to be different depending on genetics, quality of food, lifestyle, etc.

1,200 calories, plus or minus 15% depending on body build, is a normal amount of calories for a 5'4" woman with normal activity. If she eats more than that she will gain weight. If she eats less than that she will lose weight.

A 1200 calorie diet is normally based on your BMI/BMR. If you calculate a low calorie diet for someone who is 6'1" you will most certainly not get a daily calorie goal of 1200 because it's dangerously low and can impede even simple brain functions for someone that tall. I am 5'1" so a low daily caloric intake works for me. However, with every 10lbs I lose, I up my daily caloric intake because for me to maintain my goal weight I need at least 1500 calories per day. Just keep using your BMI/BMR calculator. 1200 cal/day is not a magical number, it just seems to run common with sites like MyFitnessPal and other similar pages.

Nothing like an unsolicited advertisement totally unrelated to this site to get you a nice virus. The whole purpose of this type advertising is to scam you.

So, I am brand new to this site. Not a safe place to be?

The site is perfectly safe. Its just that scammers go to sites and post links that are totally unrelated to what a site is about. All sites are prone to that. My bet is that many of the links are either viruses or solicitaions for money. If you see a link in a comment that has nothing to do w/ the topic, its either a scam, virus, or solicitation to spend money. However, in reviewing the responses above, I don't see any comments unrelated. I believe I wrote my comment, then the site crashed, and when I went back in to repost my comment, I did it on the wrong thread. Sorry for the confusion.

Oh look, unsolicited ads. Great way to get a virus by clicking on links from people who log on with questionable links.
