Hair shedding?

Hair loss is generally a problem when you aren't getting enough calories, or the right combinations of macro- and micro- nutrients. Are you on a VLCD diet? Do you frequently eat way under your goal? Have you tried to go on a really low-fat diet? All of those things could cause hair loss.

If it's a sudden change from what you're used to and you don't think you're messing up the nutrition side of things, you should see a doctor. Have some blood tests done to make sure nothing else is wrong.

Long term calorie deficit can lead to more than hair loss.

I'm fond of mentioning this: 4 orthopedic surgeries and 2 bone grafts later, learn from my fail. Supplement your diet if you can't fit in enough nutrients to keep from losing the wrong body tissues. But mainly, eat more. Eat more nutritious foods. Lose slowly.

You might be undereating, my hair started to get fuller when I started to eat more for strength training.

This happens to me and I have iron-deficiency anemia.

Hair loss (along with weight loss) when I was eating nutritionally and healthily and trying to maintain my weight was a symptom that led to my unexpected diagnosis of high blood sugar and Type 2 diabetes. My body was no longer getting nutrients from my food. Like other posters mention, if you aren't eating enough calories or not the right nutrition, it can be reflected in hair loss/health. If you are eating well and haven't had blood work done recently, I strongly recommend it.

From your ticker, it appear you have a significant amount of weight to lose. 1100 is probably too low of a goal.

I aim for a 1000 calorie deficit. Sometimes I go over and sometimes I go under. My average tends to be around 1100. I don't do low fat at all. I average 46% fat, 39% carbs, and 15% protein. I think my goal is 50/30/20, but I don't really concern myself with that too much. I just make an effort to get as much fat as I can, otherwise I feel like garbage. I do take a prenatal (I'm not pregnant, it's just that prenatal vitamins seem to have more good stuff in them).

And there's the answer: too big a deficit (assuming the OP meant daily). Try increasing food, especially fat and protein, lower carbs a bit perhaps. ADEQUATE nutrient dense foods will likely resolve this. Contrary to MFP macro defaults of 30% fat, 50% fat is a bare minimum and I would recommend more.

Hello, Hair shedding is one of the major symptoms of an underactive thyroid (Hypothyroidism). My hair started falling out and clogging up the plug hole, my skin got really dry and I was tired all the time. I also put on all the weight I'm now trying to get rid of. Definitely go to the doctor to have a blood test if you're feeling tired and have dry skin as well. You'll be on thyroxine for the rest of your life but it does help.

Your deficit is too large. Also, I'd up your protein. Speaking from my own experience when I tried to eat too low on both calories and protein. But as another user said, it wouldn't hurt to check with a doctor to make sure there isn't anything else going on.

Have you tried the Werewolf diet?

HA! ...tears...

I applaud the choice of prenatal vitamin. Does it have 100% of your vitamin D, iron, calcium, magnesium, and vitamin K? I believe those were the ones ended up deficient in. Also, if they can be cut in half, you might want to take it more than once a day.

Definitely get your bloodwork done. After losing 100#, my doctor was so happy... no, THRILLED with me. My blood pressure was down, my triglycerides and cholesterol was going down... then she looked at my anemia. Then she looked at my bone density test. Then she looked at my heart murmur.

Above all else, if your knees can handle it, please do weight-bearing, mild impact exercises to keep your bone mass up. Roller skating is a nice one that isn't too jarring on the knees.

I had that happen when my doctor recommended a 1200 calorie diet, but I didn't know about balancing macros. Thankfully I didn't stay on it very long, because I just couldn't eat that little. When I started eating normally again it stopped. Haven't had it happen since I've been at a reasonable deficit for my height/weight.

I don't understand why people are saying my deficit is too large. That is a loss of 2 lbs a week, which is pretty standard. I eat anywhere from 1600 - 1800 calories a day. I have 260 pounds total to lose (well, 190 lbs now that I have lost 70 of it). It doesn't make sense to cut back to only 1 lb a week.

They are saying it because a lot of times, it's true. Aside from a trip to the doctor's, maybe try upping your protein to around 30% and see if that helps any. When I was 245lbs, I was trying to eat at a large deficit and one of the side effects from the large deficit was hair loss.
