Are You Eating Enough? Why Under-Eating Can Sabotage Your Health

July 28, 2025

In a world obsessed with weight loss, it might seem strange to ask if you're eating enough. But chronic under-eating can be just as harmful as overeating. Here's why it's a problem and how to avoid it.

Signs You Might Be Under-Eating

If you're constantly tired, irritable, or struggling to see results from your workouts, you might not be fueling your body properly. Other signs include hair loss, constantly feeling cold, and, for women, irregular menstrual cycles.

The Dangers of Under-Eating

When you don't eat enough, your body goes into survival mode. Your metabolism slows down to conserve energy, which can make it harder to lose weight in the long run. You can also lose muscle mass, which further lowers your metabolism.

Finding a Healthy Balance

The key is to find a sustainable approach to nutrition that nourishes your body and supports your goals. This means eating enough to fuel your daily activities and workouts, while still creating a modest deficit if your goal is weight loss.

How to Ensure You're Eating Enough

A great first step is to get an estimate of your daily caloric needs. This will give you a baseline to work from and help you understand how much you should be eating. From there, you can track your intake for a few days to see how it compares.
