That's the question many people ask when their weight loss plan isn't working.

Asking yourself 'Why can't I lose weight?' is actually one of the best things you can do for yourself. It says you know that what you're currently doing isn't working for you.

You're at the place where you're ready to look at alternatives - try something different to get a result you want.

So why can't you lose weight? Here are 3 possible reasons you may not be losing weight - and some suggestions on what you can do about it.

#1) Medical Reasons

Now this is not the same as saying you're genetically programmed to be overweight. That is hogwash. In fact scientists estimate that even if you do have a genetic propensity to gain weight, your genes only account for 15 - 25% of your current weight. So forget the genetics excuse.

But there are medical reasons that some people can't lose weight. Low thyroid, adrenal exhaustion, insulin resistance and other medical conditions can make losing weight near to impossible.

That's why before starting any weight loss plan, you should talk to your doctor first. Have a full workup and make sure that you don't have any health issues standing in the way of your weight loss.

There's nothing more frustrating that trying to lose weight, doing all the right things and not losing an inch - all because of a medical condition. Get the medical condition cleared up first and then address the weight (in fact, the weight may just go down on it's own once you get the medical condition addressed).

#2) Emotional Eating

I recently read an article where a nutritionist estimated that 75% of overeating was due to emotions. 75%! Can you imagine what would happen if you learned to eliminate emotional eating and cut out all those calories? What a weight loss impact! The weight would be falling off.

Unfortunately, in today's world, emotional eating is on the rise. Most people today are feeling the pressure of an increasingly hectic lifestyle. We hardly have time to tie our shoes, never mind deal with our emotions.

Because of this, our emotions get stuffed down and ignored until finally they explode and we're face-down in a bowl of Rocky-Road ice cream with extra chocolate sauce.

Here's the bottom line: you are human and you have emotions. Your emotional needs are important and need to be addressed properly with love. You need emotional nurturing and proper emotional care.

If that means you take a 5 minute break every few hours at work to regain your emotional balance, do it. If that means you need to unwind by doing a mall walk and window shopping after work - don't let anything stop you.

Learn to nurture your emotional health and you'll nip emotional eating in the bud - and start losing weight FAST.

#3) Mismatched Weight Loss Plan

There are many different ways to lose weight and dozens of weight loss programs to choose from. Some plans emphasize a change in diet, others emphasize a change in exercise, others focus on the inner reasons for overeating.

Every person is different and will lose weight in their own unique way. If what you're doing now isn't currently working, it may be a simple case of personality-plan mismatch.

Maybe instead of a diet-focused weight loss plan, you would feel better with a fitness-focused weight loss plan or a psychological weight loss plan. There are lots of plans to choose from and you deserve to take your time and find one that fits your personality and lifestyle best.

If you think this is the case, take some time to review different diet or weight loss plans. Find one that you can get excited about, one that makes sense to you and that fits your belief system and personality. That's when you'll make real weight loss progress!

So those are 3 possible reasons for your weight loss plateau. You don't have to stay stuck in a weight loss rut. You don't have to keep asking yourself the frustrating question: Why Can't I Lose Weight?' Keep believing in yourself and in your dreams. Don't give up and you will get there!
