It is a common misconception that fatigue and drowsiness are the same thing, but drowsiness is considered to be just one symptom of fatigue. Although fatigue is common, prolonged occurrences can result in a more serious condition. The National Institutes of Health defines fatigue as "a lack of energy and motivation," and drowsiness as a "need to sleep." Your protein intake, whether high and low, might be a factor if you are experiencing fatigue.
Fatigue and Diet
Fatigue can occur for a number of reasons, such as stress, lack of sleep, boredom and physical exertion. However, fatigue can also be caused by what you eat. When your body is lacking nutrients, it responds in different ways. Your body might react through both emotional and physical changes -- fatigue can fall into either category. If you are experiencing signs of fatigue, begin by making healthy lifestyle choices. Practice good nutrition, get enough sleep and reduce stress levels. If you are still experiencing signs of fatigue, consult your physician for further treatment.
Low-Protein Diet
In October 2000, the Journal of American College Nutrition published a study that indicated people who participate in regular physical activity have an increased need for protein. The study has some flaws because other factors such as age, gender, protein type, activity type and intensity might also affect protein needs, but the end result remains the same -- the more active you are, the greater your protein needs. If you follow a low-protein diet or currently don't get enough protein in your diet, it is possible you might experience fatigue due to your intake or lack thereof.
High-Protein Diets
Experts at the Mayo Clinic say that "for most healthy people, a high-protein diet generally isn't harmful if followed for a short time." When you fallow a high-protein diet, you are required to limit your food intake from other groups. Commonly, a high-protein diet results in a low-carb diet. This might not be a problem right away, but when you limit your carb intake, you also begin to lose the benefits associated with eating from that particular food group. It is possible to experience fatigue on a high-protein diet because you are losing the energy you get from carbs, which help regulate your blood sugar and can give you a quick spike of energy after consumption.
Daily Protein Needs
Every individual has different protein needs, but generally speaking, the U.S. Department of Agriculture recommends that healthy adults consume between 5 and 6 oz. of protein per day. To change up your routine, try varying your protein sources. Dairy products, fish, eggs, meat and poultry are all protein-rich foods. Add cheese or chicken to your salad to get extra protein with your meal. Consider changing up your recipes to help you meet your daily needs.
