General Question


I am on a diet and have lost some weight already. Why do I feel so tired?

Asked by MRSHINYSHOES (13951points) March 7th, 2010

I have been on a diet for the past month. I’ve lost about 2–3 pounds already. How come I’ve been feeling so tired? Is it because of the lost of weight, a nutritional deficiency, etc.? I am eating sensibly and taking my vitamins. Is this feeling of tiredness normal with the accompanying loss of weight? What can I do to offset my tiredness?

There is no reason you should feel tired because of the weight loss – but you may absolutely be nutrient deficiency is your diet is missing key nutrients. You should figure out what’s missing, if you can – maybe, see a nutritionist.


@Simone_De_Beauvoir Hmmm, I think I will, or my doctor at least. It’s strange, but I’ve been on diets to lose weight before, and everytime I encounter the same problem. I am exercising at the same time, with weights and swimming. Maybe I’m overdoing it. Thanks Simone!

@MRSHINYSHOES There may be an underlying cause – what kind of a diet is it?

Are you drinking enough water? Water is hugely important to overall well being and most people do not drink enough water.


@Simone De Beauvoir——Just a normal diet with the four food groups. The only thing that’s different is that I’m cutting back on my calories by eating less, and going to bed a bit hungry. I am guessing that the loss of calories, coupled with my exercise, is making me tired. :(


@SeventhSense, yes I am drinking a lot of water and other fluids.

You may just need some getting adjusted to the new pattern. Every time I restrict some calories, I get a little cranky and my body’s first reaction is to slow down and preserve some fat. If i am persistent I get a second wind and start burning some of those “reserves”.

I don’t think you should allow yourself to go hungry. Eat a lot of high fiber foods if you’re not already.. they keep you fuller for longer periods of time. I usually carry baggies of fruit or baby carrots to snack on throughout the day. A hard boiled egg will do it too. If you eat every couple hours you shouldn’t be feeling hungry and perhaps it will help with your exhaustion as well.

If you’ve only lost 2 or 3 pounds, this is unusual. It might be normal if you lost 10 in a month.
Go to the doctor.

Do you eat a lot of red meats?you could be anemic


@Eap6389 I don’t eat a lot of red meat. For protein, I drink whey protein drinks. I take a multi-vitamin with minerals, but without iron.
