If it’s been a while since you last ate, there’s a good chance you’ll experience a significant drop in energy, signaling it may be time to grab a snack. Especially if you got a good night’s sleep, this dip in energy could be a telltale sign that your body is asking for food.
It’s also important to note that a high-carb meal may cause a blood sugar spike, followed by a subsequent crash, which could also be the culprit: “When these insulin levels peak after eating, this can lead to a crash in our blood sugars–leading, understandably, to that all-too-familiar post-lunch slump–a foggy brain and tired body,” says Uma Naidoo, M.D., nutritional psychiatrist, professional chef, nutrition specialist, and author.
It’s ultimately key to take a look at your day up until that point–did you eat a meal or drink water recently? Even if the answer is yes, was your meal small or high in sugar? These are signs you may still need some more nutritious fuel (ideally with a balance of protein, healthy fats, and fiber), even if it hasn’t been long since you last ate.
