It’s extremely common that when people think they’re eating enough, they are actually under-fueling their bodies. Under-fueling can lead to not losing weight at the rate you want or even gaining weight.
There are some key signs your body may be sending you that it is chronically under-fueled. If you notice any of these signs on a regular basis, you need to double-check that you are eating enough calories for your size, age and activity level.
- You aren’t hungry anymore. Not being hungry can mean a lot of different things. It can mean your body is no longer craving food or that you’re full from the meal you just ate. But it can also mean that your body isn’t getting the nutrients it needs to function properly. If you’ve noticed that you’re not hungry even when you haven’t eaten for hours, then it could be because your body hasn’t been getting enough calories to properly digest food.
- You might feel dizzy or light-headed after eating. If this is something that happens often, then it could be because of a lack of calories. When there isn’t enough glucose in the bloodstream, the brain can’t get the fuel it needs, which leads to light-headedness and dizziness. However, this only tends to happen if an individual has skipped several meals throughout the day
- Fatigue. If you’re constantly fatigued, you might not be eating enough food to keep up with your energy demands. That can lead to reduced performance in the gym — and poor recovery between workouts — as well as a general lack of energy throughout the day.
- Frequent illness. A healthy immune system is critical for staying healthy, but there’s some evidence that low-calorie diets can make people more susceptible to colds and other infections. Not eating enough protein can also have this effect, because proteins are the building blocks of important immune cells.
