Signs You're Not Eating Enough

Let me ask you a question I ask MOST people....

Are you eating enough?


Do you know how much you SHOULD be eating?

Majority of clients coming to work with us here at Clar-e-ty are eating too few calories and/or doing too much.

It’s way more common for us to get an incoming client reporting an intake UNDER 1500 calories than it is to see an incoming client eating above 2000 calories (where we would LOVE in a future world all humans would be eating). Clar-e-ty has worked with over 100 clients and probably can count one hand the number of incoming intakes averaging above 2000 calories. That's something we have set out to change in this "eat less, do more" world.

From our experience, MOST people—men AND women alike—should be eating a diet well above 2000 calories to support not only their body’s normal function but also exercise, work, and all the stress their bodies are put through on a daily basis.

YET in many cases, this isn’t the case. Males often average around 1700-1800 calories, while women average around 1200-1300 calories.

What sucks MOST about undereating is that it usually takes months...if not fix depending on 1. the severity of the deficit the client was in and 2. the mental state and mindset the client feels with adding food to his/her intake.

Because it’s SUCH a common thing and probably the most under-discussed topic in nutrition, our goal today is to teach you all about under-eating: why it’s likely not good for you, how it probably all started, signs YOU may be experiencing if you’re under-eating, and most importantly how to fix it.



This world thrives on the phrase “eat less and do more.”

It’s a really common phrase and tagline weight loss “specialists”, companies, doctors, trainers, etc. use...because the science says “eat less = calorie deficit = weight loss”

But in more cases than not, the opposite is true...

Eat more and do less

It’s pretty much exactly as it eat more calories and do less get desired results.

So let’s go back to that classic client eating sub-1500 calories.

SO what does this really mean? Does it matter? Why are we such sticklers for eating enough food? If they’re fine eating less than 1500 calories, what does it matter? I actually see all the time on nutrition posts encouraging getting away from such low calorie diets people saying things like “it’s not your business what they’re eating” and “if they’re happy and alive, that’s what matters” and “who cares” and so on.

Eating too little and doing too much poses a couple of problems.

  1. Your body needs to be fueled

  2. You’re likely not actually feeling “fine” (you just think you are)

  3. You likely don’t know how much better you could feel (have you ever eaten to support every function of your body??)

  4. You need a foundation to cut from in order to see results (try cutting from 1200 calories)

  5. Stress management (under eating = stress = cortisol = poor sleep, etc. = more stress)

AND YES, your body is your body. We can’t tell you what to do. That part is absolutely true...

But we can educate you on maybe some things you weren’t aware of so your decision can be better informed...and if you don’t see results you at least know WHY.

The reason so many seek Clar-e-ty as their nutrition coach is more often than not to help a client achieve a specific body composition goal...most often weight loss.

But in every single case of an underfed incoming client, we can't target weight loss initially. If you’re undereating, you don’t have a place to cut from (you’ll see in the example below) nor do you have the health (metabolically, hormonally, etc.) to sustain and manage a calorie deficit, which makes the process a lot tougher...for you & your coach!

Now we do get a good bit of resistance when it comes to adding food into your diet...mostly because we're initially hired to help a client lose weight...but in order to do so, you’ve got to be in a healthy place with a strong foundation...and MANY don’t have that and therefore have to take some time earning the right to diet.

So let's talk a bit more about under-eating and how it all starts...because not many of you likely set out 5-6 years ago going "OKAY, today let's starrrvveeee and not feed ourselves."


When it comes to weight loss there is ONE factor that is ALWAYS true.

Calories in must be less than calories out.

That’s how “eat less do more” came about.

When you were younger, you likely ate more intuitive (aka...enough! Have you ever seen a baby eat? It's very much along the lines "I'm hungry & now I will eat & now I will stop because I'm full.")...

But at some point, popular diet culture infiltrated your brain and you started dieting. Let’s make numbers easy and say maintenance eating (where calories in=calories out) probably had you around 2000 calories. abide by “eat less do more” you created a 500 calorie deficit by either adding exercise or taking away food (or both). Now you’re down to 1500 calories. For a short period of time, especially while biofeedback is good, this is absolutely fine. I personally have successfully and healthily dieted on 1500 calories, along with several clients.

Sounds great, right?

Let's move on.

The problem arises from AFTER the diet is done....when there is no “after-diet” where you brought your intake back up to 2000 calories.

What happens? Your metabolism adapts.

What does that mean? Your metabolism accounts for your basic bodily survival mechanisms. It includes your organs functioning, your heart pumping, your digestion, your immune system, everything you'd need to survive if you were a couch potato. However, when your body senses a reduced intake, it perceives that as a stress and therefore will "slow down" some non-essential processes. This includes digestion, reproductive health, hormone health, immune system, etc. It does so until your new "calories out" is matching your intake. Because you're not fueling yourself too, you also slow down (almost unconsciously). You don't move as much. You fidget less. You don't workout as hard or as long. You take fewer walks. You continue to burn fewer calories.

NOW your new normal “maintenance” is 1500 calories because that's the number of calories your body is surviving off of.

Fast forward 2 years and you want to lose weight again. NOW to create that deficit, you can’t rely on your 1500 calorie intake to you need to eat less. This time you go 1200 calories...and again you see weight loss but the same thing happens and you don’t have the diet after the diet to return your intake back to its maintenance. NOW in order to ever lose weight, you have to cut from 1200 calories.

Which plain out sucks and honestly is why we do what we do.

It mostly isn’t your fault...because you were never told the repercussions of eating too little. No one gave you a disclaimer: “If you follow this diet, you may experience the following: crappy sleep, terrible PMS symptoms, no sex drive, injuries, awful sleep, midday crashes, oh and wait you may not ever be able to diet again.” I can bet if you think back to your very first diet, you likely knew something was off...but no one was standing in front of you saying “there’s a better way!!”

Until now!


The first question really comes down to “are you eating too little OR doing too much?

Here are some signs your calories are too low:

  • Brain fog, inability to focus, lack of mental clarity

  • No appetite or desire to eat

  • Frequent injuries

  • Midday energy crashes

  • Wake up frequently (to pee, mind racing, inability to fall asleep, wired, etc.)

  • Carry weight around your midsection

  • Inability to lose weight

  • High cravings

  • Absent or irregular cycle

  • Low/no sex drive

  • Mood swings/irritability

  • Worsened immune system

There could be other signs, but from our experience personally and working with clients, these are the classic ones. These are all signs that your metabolism has adapted. This creates stress on your entire body, specifically your adrenal glands (your stress factory essentially). Your hormonal, metabolic, and reproductive health all take a hit. You’re at risk for more injuries. Most just feel like crap.

Cravings are a classic sign that you’re undereating...especially if you’re binging. It’s not a matter of you being “weak” but actually your body begging for some support...via calories.

We've also included “doing more” in the category. This could be spending 2+ hours in the gym, taking very few rest days, living in the cardio world and including no resistance training, letting every gym session absolutely crush you, maxing out frequently, etc. In my experience, most of my “doing too much” people are either spending way too much time on cardio and not enough time lifting weights OR just not taking enough rest days.
