I've lost 15 lbs in the past two and a half weeks (185 to 170) without really any change in exercise. I did make some changes to my diet, but nothing that I thought would cause this dramatic of a decrease (less red meat). I don't feel sick, but maybe a little more tired then usual. Any ideas of what could cause it?

AIDS

Could be cancer.

In any case, you need to see a doctor ASAP.

Dying battery in scale.

tapeworm

diabetes--whether mellitus or insipidus
hypoglycemia
less protein and/or iron

check celiac disease (wheat/gluten allergy). That can come on later in life, and when you have wheat, it will mess with your metabolism and prevents you from absorbing calories

drinking all that coffee

If you are concerned about any of those diseases - seriously, go back to your old diet and see if the weight still comes off. If it does, you've got medical problems.

If you maintain or gain weight, then you are just underestimating the effect even a short-term change of diet can have.

In the first two weeks of any diet program (even if unintentional), losing that much weight is EASY for the vast majority of guys. Odds are that eating less red meat and a few other small changes drastically changed your desire for other crap food, and you probably ate less than you believe you did.

AKA - you're fine. The fact that your change in energy and weight came at the precise time your diet changed is a virtual guarantee that the diet caused the difference. It is highly unlikely that you have those diseases in the first place, and then it's even more improbable that they started manifesting themselves this way at the precise time you changed your eating habits.

if you cut out carbs significantly, that's probably mostly water weight

^^ I think you're right. On top of that, added stress at work in the last three weeks probably helped too. I'll make an effort to eat a little more and see if it curbs the loss. Thanks for the input

This summer I got to the point where I was eating a meal a day. Schedule changes and whatnot can make you forget to eat or eat less and you'll be calorie deficient. Just be sure to balance your calorie intake.

Too much coke?

9/1/2009 9:25:12 PM

Could be mono.

9/1/2009 9:37:06 PM

Could be a lot of things.

You pissing every 20 minutes?

I wish this would happen to me.

A) check your caloric intake now compared to a couple of weeks ago. If you were maintaining the same weight before, you were getting the amount of calories necessary to neither gain nor lose weight. It could be that in changing your diet, you're getting less calories than your using and thus losing weight. That's how that works (for dummies version). Was this a calculated change in diet? As in you are paying attention to nutritional intake? Or was it more, I need to eat less red meat, so I'll just eat this stuff without much thought as to what you were actually taking in in regard to nutrients and calories from said nutrients?

It may just be that you need to eat more of these new foods to maintain your weight. Also, even if you're happy with the -15lbs, you'll keep losing weight if it is calories intake or lack there of causing it. So if so, add a few hundred calories to your daily diet and see if you start to level off.


B) make sure there's nothing wrong with your scale


C) if A and B both prove to not be a factor, see a doctor.
