Can You Be Too Healthy to Conceive? How Over-Exercising and Under-Eating Affect Fertility

In today’s health-conscious world, many people strive for peak physical fitness and clean eating. While these habits are generally beneficial, it’s possible to take healthy living too far—especially when it comes to fertility. Over-exercising and under-eating can disrupt your body’s delicate balance and make it harder to conceive.

How Does Over-Exercising Impact Fertility?

Exercise is vital for overall health, but excessive physical activity—particularly intense cardio or endurance training—can interfere with reproductive hormones. Women who work out heavily may experience irregular menstrual cycles or even stop ovulating altogether. This condition is sometimes called exercise-induced amenorrhea.

When your body senses it’s under physical stress or not getting enough energy, it prioritizes essential functions for survival over reproduction. This means hormone levels like estrogen and luteinizing hormone (LH) can drop, preventing ovulation and lowering fertility.

The Role of Under-Eating and Low Energy Availability

Alongside over-exercising, under-eating or not consuming enough calories to support your activity level can cause a condition known as low energy availability. This occurs when your body doesn’t have enough fuel to maintain normal physiological processes, including hormone production.

Low energy availability disrupts the hypothalamic-pituitary-ovarian (HPO) axis—the hormonal system that regulates your menstrual cycle and fertility. As a result, you may experience irregular or absent periods, diminished ovarian reserve, or difficulty maintaining a pregnancy.

Signs You Might Be Overdoing It

Some signs that your fitness routine or diet might be affecting your fertility include:

• Missing or irregular menstrual periods
• Extreme fatigue or difficulty recovering from workouts
• Sudden weight loss or being underweight
• Frequent illness or injuries
• Feeling cold or experiencing hair thinning

If you recognize these signs, it’s important to speak with a healthcare provider who understands the link between fitness, nutrition, and reproductive health.

Balancing Health and Fertility

Achieving a balance between healthy habits and fertility is key. Moderate exercise, a nutritious and adequately caloric diet, and proper rest all support reproductive function. Consulting with a fertility specialist, nutritionist, or endocrinologist can help you develop a personalized plan that supports both your overall health and your goal to conceive.
