Become adept at noticing the signs and symptoms your body signals to inform you that your food intake may be insufficient.
Factors such as stress, hectic routines, illnesses, grief, and the fast pace of daily life can greatly affect us, especially our appetites and the mechanisms our bodies use to manage hunger. This often results in not eating enough. Moreover, many individuals aiming for weight loss may unintentionally limit their food intake or restrict it in pursuit of that goal.
No matter the reason, inadequate food consumption and the lack of essential nutrients can appear in ways that disturb your metabolism and hormone levels, often taking time to recognize if you’ve been consistently under-eating.
Let’s explore the telling signs that your body may not be receiving enough crucial protein, carbohydrates, and fats, along with strategies to enhance your food intake through a well-rounded diet.
If you’ve been experiencing extreme fatigue for an extended period despite adequate sleep, it may be time to reassess your diet. When we habitually consume insufficient food, our bodies lack the necessary fuel, leading to feelings of lethargy and sluggishness.
This is particularly noticeable in low carbohydrate diets. Since starchy carbohydrates serve as the body’s main source of quick energy, it’s understandable why limiting them can result in less-than-optimal energy levels.
Evaluate your usual food intake in terms of both quantity and variety. Are you incorporating all the components of the Foundational Five into balanced meals? Including starchy carbs? Are you consuming food in response to hunger and tuning in to your body’s signals? Take a moment to reflect and see if adjustments can be made.
Dizziness can serve as an early physical indicator of inadequate food intake. Insufficient food can lead to a drop in blood sugar levels, causing feelings of dizziness or lightheadedness. If you frequently feel faint and can’t pinpoint the cause, check your food consumption.
For a quick energy lift, try snacking on something containing both carbohydrates and protein, like a banana with almond butter, a handful of nuts and berries, or veggie sticks with hummus. This blend will help elevate and stabilize your blood sugar levels, boosting your energy.
However, if dizziness continues despite dietary and lifestyle changes, consult your doctor to rule out any underlying issues.
Do you ever find yourself forgetting things, asking, “Where are my keys?” While this can happen to anyone, persistent brain fog might signal that it’s time to evaluate your nutrition (i.e. eat more)! This condition can stem from various health issues but is also a common symptom of inadequate daily food consumption.
Delaying meals or interrupting regular eating times for work commitments can hinder the energy your body needs. So when that 3 p.m. slump hits, consider that you may have skipped lunch—your cue to seek out a meal or snack.
Opt for wholesome foods whenever possible. A generous salad with fresh vegetables, perhaps some sweet potatoes, avocado, grilled chicken, or your preferred protein, along with a delicious dressing, is a great choice. Foods high in B-vitamins, omega-3 fatty acids, folate, and antioxidants can enhance brain function and prevent cognitive decline (1). Say goodbye to brain fog.
You might be surprised, but not consuming enough food or nutrients means that higher-priority organs, like your brain, heart, and lungs, will take precedence when it comes to nutrient absorption—leaving hair, skin, and nails at a disadvantage. The health of these features is closely linked to your dietary choices and nutrient absorption.
A daily loss of 50-100 hairs is normal, but if you notice increased shedding or that your nails are more prone to breaking, it could be time to nourish them from within.
Focus on consuming foods that boost keratin production, the protein vital for strong hair and nails. Excellent sources include spinach, beans, oats, salmon, eggs, and berries. Nutrients like protein, biotin, iron, vitamin B12, and omega-3 fatty acids are particularly beneficial for hair and nail health.
Experiencing anger from hunger is very real! If you’re juggling a busy day and skip breakfast, you could see a significant drop in mood and blood sugar levels. Research indicates that low glucose levels can lead to irritability and aggression (2). Thus, if you often feel irritable after not eating, it may reflect your insufficient calorie intake.
To avoid these feelings, aim for regular meals and satisfying snacks. Having consistent meal times helps maintain stable blood sugar levels, allowing you to feel positive and energetic. When you first notice hunger signs, respond without delay; grab a meal or snack based on your hunger level to stay your best self rather than becoming moody.
Do you often feel chilly? You need adequate food intake to keep your body warm while it carries out other functions.
Without enough food, your body struggles to perform thermogenesis, the process that generates heat. Research indicates that individuals on restrictive diets tend to have lower body temperatures compared to others (3).
Women who are underweight or possess low body fat might develop “downy” hair, known as lanugo, as a means for their bodies to combat heat loss. If your body lacks sufficient fat for warmth, it may grow lanugo to assist in heat retention—a condition prevalent among individuals with anorexia nervosa or those who are extremely thin.
Ensuring you eat adequately can aid in managing your hydration levels. Various electrolytes from food impact your thirst, such as sodium, potassium, and magnesium. If you remain thirsty despite drinking plenty of water, it’s a warning sign that your calorie intake may be too low.
Your body can also confuse hunger with thirst, leading you away from your water source. Always aim for hydrating options like caffeine-free teas, carbonated unsweetened seltzers, and good old water.
Amenorrhea refers to the absence of menstruation. Women might miss periods for various reasons, including pregnancy, dietary changes, and stress. Certain medications, including contraceptives, may also affect menstrual cycles. Specific health conditions like hypothyroidism and polycystic ovarian syndrome can also disrupt hormone levels and influence periods.
Missing your period can also occur from insufficient food intake, particularly with low body fat or being underweight (approximately 10 percent below “normal” weight), which varies per individual. Being underweight can interfere with ovulation and trigger hormonal imbalances, so women with eating disorders or high-performance athletes may often skip periods to due insufficient nutrient intake.
The female athlete triad encompasses a linked series of low energy intake, amenorrhea, and reduced bone density, frequently seen in athletes striving to maintain specific “lean” appearances in sports like figure skating, ballet, or gymnastics.
The key takeaway from this article is to remain vigilant and attuned to yourself and your body’s signals that indicate something may be amiss. Use these 8 signs and symptoms to assess your situation and decide whether you might need to increase your energy intake.
