It may be normalized to complain of low energy, but chronically low energy levels are certainly not normal and there may be a nutrient deficiency causing fatigue. While specific nutrient deficiencies are associated with low energy, you’ll want to consider whether or not you are taking in enough energy—literally, from calories—first.
As logical as it sounds, many people make the mistake of jumping into the world of micronutrient deficiencies before considering whether or not they have been in a calorie deficit for an extended period of time. Even if your calorie deficit has been unintentional, it can be affecting your energy levels in a big way. Some simple questions to consider first are whether or not you eat three square meals, regular snacks, and drink plenty of water every day. These are the bare minimum requirements to make sure that you are nourished and not in a calorie deficit.
