What are signs you are not eating enough calories?

When you're not eating enough calories, your body sends clear warning signals. Constant fatigue and low energy are among the first signs, as your body lacks fuel to function properly. You may also experience persistent hunger, difficulty concentrating, brain fog, and irritability. Physical signs include feeling cold all the time, hair loss, dizziness, and headaches. Other indicators include losing muscle mass, frequent illness due to a weakened immune system, and slowed metabolism. Women may experience irregular or missed periods. You might also notice intense cravings, particularly for high-calorie foods, as your body tries to compensate for the deficit. If you experience several of these symptoms consistently, it's worth evaluating your caloric intake with a healthcare professional.
