More curious than anything. What happens if you lose too quickly or go under 1200?
What problems develop?

    My friend was eating 1100 calories and lost a lot of hair. Luckily for her she already had thick hair so it wasn't that noticeable to others, but she noticed everytime she brushed or washed her hair. It devastated her. She also couldn't sleep and had no energy was irritable and suffered from extreme anxiety during that time. So bottom line eat 1200 or more.

    Hair loss won't show up for months after the under eating begins.

    What Are the Risks of Rapid Weight Loss?

    Rapid weight loss creates physical demands on the body. Possible serious risks include:
    • Gallstones, which occur in 12% to 25% of people losing large amounts of weight over several months
    • Dehydration, which can be avoided by drinking plenty of fluids
    • Malnutrition, usually from not eating enough protein for weeks at a time
    • Electrolyte imbalances, which rarely can be life threatening

    Other side effects of rapid weight loss include:
    • Headaches
    • Irritability
    • Fatigue
    • Dizziness
    • Constipation
    • Menstrual irregularities
    • Hair loss
    • Muscle loss

    There's nothing magical about the number 1200. However, all kinds of problems come from not eating enough.

    Over time, you become deprived of important vitamins which can cause fatigue, skin rashes, hair loss, loss of libido, and other unpleasant things.

    I ate about 1000 cals a day for 8 weeks. Lost a lot of weight of course, now at maintenance, had no problems.

    Unfortunately, you probably lost a lot of muscle too.

    Not to much

    I ate at the prescribed amount and started losing. So I upped my exercise (running) and lost more. I decided I was going to crush this and went way below on my calorie count. I didn't lose any measurable amount more, felt so sick I had to increase calories and stop running for days. I was more effective when I ate at a slight deficit and worked out. I felt so much better too.

    IF you are a healthy shortie and you balance your Macros to eat more protein, healthy fats, lots of veggies, and a multivitamin then I think it is doable to be a bit under 1200 cals.

    The problem is that you will miss out on necessary macronutrients for life. The body then pirates what it needs from elsewhere, typically protein. This is the muscles and can include the heart muscle.

    Non essential functions like hair, new skin, nail growth and the reproductive cycle are shut down.

    These consequences may not show up for weeks after the damage is already done.

    There can be general weakness and dizziness. Hang on to the railing.

    I typically mention the cosmetic consequences as this seems to deter people faster than the other ones.

    what he said, the body eats at muscle (which includes the heart muscle) instead of stored away fat, which in turn makes it HARDER to lose ACTUAL fat. Lack of nutrients deplete of your intestines of the energy they need to function which can result in their failure, gallstones, higher susceptibility to disease and infection because your immune system is lowered. Heart attack because your heart is under so much strain.

    Unless you are on a very closely monitored diet - generally in a hospital and most likely being fed with a tube. It's incredibly difficult to get the micro and macro nutrients you're body needs in less than 1200 calories a day.

    Once in a blue moon, such as having a nasty stomach bug so you can't keep anything down for a day or two, won't hurt you. Over time not getting enough nutriets will start to deteriorate your organs, skin and hair will be most noticable, but also your internal organs will suffer.

    you would still lose fat. your body will use anything it can to continue to try and funtion that includes fat too.
