You’re Not Eating Enough for Your Workouts If You Notice These Signs

If you seem to always be following a diet, then you probably follow the basic rules for healthy eating: Eat plenty of fruits and veggies, always choose whole grains over refined ones, and never eat just before going to sleep. You may even be so strict with your diet that you feel drained of energy before your workout even begins.

While it may seem like the only way to lose or maintain your weight is to keep your intake under a certain number of calories each day, you have to support your body with the proper amount of nutrients to get through those grueling cardio and weight sessions. Here are the signs you may not be eating enough to fuel your workout regimen.

1. You’ve stopped losing weight

If weight loss is your goal, then you know the general rule of thumb is you need to expend more energy than you consume. But if you’re training six to seven days a week and cutting back on carbs, sugar, fat, and calories, it’s likely you’ll eventually reach a point of overtraining. Your body won’t be able to keep up with the physical demands and your progress will start to halt completely in terms of stamina, strength, and weight loss.

ShapeFit explains overtraining along with making severe cuts to your diet can result in a hormonal imbalance, which can stall muscle growth. You’ll begin to put on fat easier as well, even with your strict diet and intense workouts.

2. You’re exhausted

A lot of fitness professionals recommend eating a small snack an hour or two before your exercise or a larger meal up to four hours before an intense workout. If you neglect to properly fuel your body, you’ll burn out quickly. says eating enough for your workout, particularly earlier in the day before your training begins, is vital for having enough energy to properly execute the moves without feeling fatigued.

While eating a boatload of carbs before your workout is unnecessary, you will need to eat a combination of foods that offer carbs, healthy fat, and nutrients so you don’t tire too quickly.

3. You’re recovering slowly and poorly

Soreness is typical for those who have a regular fitness routine, but if the sensation lingers for long stretches of time, then it’s likely you aren’t eating enough post-workout. BoxLife Magazine reports your body will function at a lower level if you aren’t giving it the fuel it needs, and you won’t be able to recover properly if you aren’t eating enough, especially after a workout.

The 20 to 30 minutes immediately after finishing your workout is when the protein in your muscles is being broken down. If you’re looking to gain muscle mass, this is the perfect time to take in some protein and carbs.

4. You’re irritable

It’s one thing to wake up on the wrong side of the bed once a week or so, but if you find you’re grouchy morning, afternoon, and night, then there may be an underlying issue. Self explains those who chronically under-eat are at high risk for irritability. This could be because food itself stimulates the area of the brain that receives pleasure.

Not only does your blood sugar plummet when you haven’t eaten, but the hunger hormone known as ghrelin is also triggered, as is your adrenaline. This combination of hormones can lead you to snap at anyone who looks at you the wrong way. As far as your workouts are concerned, these negative feelings may reflect a poor performance in the gym.

5. You can’t fall asleep

While you may blame working out late in the evening for your insomnia, it actually might be your restricted diet that’s really giving you trouble. Chris Kresser explains sleep quality often suffers for those who aren’t eating enough. The same goes for those who wake up multiple times during the night. When you under-eat, your blood sugar is going to be unstable, releasing cortisol and adrenaline to compensate. If these hormone levels get too high, you won’t be able to sleep.

If you’re experiencing difficulty sleeping soundly through the whole night, try adding a little more food to your diet — you can even add in a healthy snack an hour or two before your bedtime, but go for something light.

6. You’re always hungry

You may have those days where your insatiable hunger takes over after a long, hard workout. But if your stomach is growling 24/7, it could be the sign you need more calories in your diet. Healthline explains if you’re drastically slashing calories, your body’s natural response is hunger pangs and food cravings — and it’s not always healthy to forget about these signs.

While you may be inclined to ignore a growling stomach in hopes of cutting body fat, you should try adding in high-protein and high-fiber foods into your diet. If you’re still hungry, monitor your calorie intake and make sure you’re getting enough.
