You make time for workouts, get your steps in, and try to make nutritious food choices. But have you ever stopped to ask yourself whether you're eating enough to support everything you're asking your body to do?

It's easy to focus on eating less when thinking about nutrition and weight management. However, your body needs energy to exercise, recover, build muscle, concentrate, and carry out everyday functions.

7 Signs You May Not Be Eating Enough

1. You're constantly tired. Persistent fatigue may indicate that your body isn't getting enough energy or that something else needs attention.

2. Your workouts feel harder than usual. Insufficient energy and carbohydrate intake can affect exercise performance. Fueling consistently before and after exercise can help support performance and recovery.

3. You're extremely hungry at night. If you eat very little during the day and find yourself ravenous in the evening, your body may be responding to inadequate daytime intake.

4. You're always thinking about food. Constantly thinking about your next meal or struggling to concentrate because you're hungry may be signs that you need more nourishment.

5. Your recovery is slower. If you experience persistent muscle soreness, declining performance, or difficulty recovering between workouts, review your overall fueling and training schedule.

6. Your menstrual cycle becomes irregular. For people who menstruate, consistently inadequate energy intake can disrupt reproductive hormone function and contribute to irregular or absent periods. Menstrual changes deserve medical attention.

7. You're experiencing frequent injuries or getting sick often. Low energy availability can affect bone health, immune function, and recovery.

How to Fuel Before and After Workouts

Before: Try a banana and peanut butter toast, oatmeal with fruit, yogurt with granola, or crackers and cheese. Choose foods that feel comfortable in your stomach.

After: Your body benefits from carbohydrates to replenish energy stores and protein to support muscle repair. Easy combinations include Greek yogurt with berries and granola, eggs with toast and fruit, or a chicken, rice, and vegetable bowl.
