As a nutritionist, I want to address a concerning trend in modern dieting: the overemphasis on counting macros (macronutrients) and calories at the expense of micronutrient consumption. This narrow focus can lead to significant nutritional deficiencies that may have severe health consequences. In this article, we’ll explore the importance of micronutrients, the dangers of neglecting them, and how to achieve a balanced, nutrient-rich diet.
While calories and macros (proteins, fats, and carbohydrates) are undoubtedly important for energy and body composition, micronutrients play a crucial role in maintaining overall health and preventing the development of various health conditions. Micronutrients, which include vitamins and minerals, are essential for numerous bodily functions, including immune system support, cognitive function, energy production, and more.
Beyond Calorie Counting
Calorie tracking and counting macros can be a useful tool for weight management, but often when done poorly it fails to account for the nutritional quality of food. For instance, 100 calories of spinach and 100 calories of processed snacks have vastly different micronutrient profiles. By focusing solely on calorie intake, individuals may inadvertently consume nutrient-poor foods, leading to micronutrient deficiencies over time. While excessive consumption of processed foods is a common concern, even seemingly balanced diets can pose nutritional risks.
The popular “chicken, rice, and broccoli” meal plan, favoured by many fitness enthusiasts, may appear nutritionally sound at first glance. If we count macros for that meal on average we would get quite a balanced meal. However, when followed exclusively, this limited diet can lead to significant nutritional deficiencies. A strict ketogenic diet which is another one popular among fitness enthusiasts limits fruit and vegetable intake, potentially leading to deficiencies in vitamins C, K, and various B vitamins. On the other hand, extremely low-fat diets can impair the absorption of fat-soluble vitamins (A, D, E, and K) and essential fatty acids.
The Hidden Danger of Counting Macros and Micronutrient Deficiencies
Micronutrient deficiencies are often referred to as “hidden hunger” because they may not be immediately apparent but can have devastating long-term effects. Many people worldwide are estimated to be deficient in key vitamins and minerals, particularly vitamin A, iodine, iron, B1, B6, calcium, magnesium, phosphorus and zinc. This issue is not limited to developing countries; even in affluent societies such as Australia, poor dietary choices can lead to significant micronutrient deficiencies such as:
– Chronic burnout and weakness
– Compromised immune function
– Impaired physical and cognitive development
– Pregnancy complications, or difficulty conceiving
– Reduced productivity and work capacity
– Delayed wound healing
– Increased risk of chronic diseases and many more.
Symptoms of Micronutrient Deficiencies
As a nutritionist, one of the most common issues I help clients overcome in my practice is hypothyroidism. This condition is often the result of years of restrictive dieting, yo-yo dieting, obsessive macro counting, and following other limiting eating patterns. These practices over time lead to chronic nutrient deficiencies and metabolic imbalances, which ultimately compromise thyroid function. Many clients come to me frustrated by unexplained weight gain, persistent fatigue, constantly feeling cold, muscle and joint aches and pains and other symptoms, unaware that their past dieting behaviours have contributed to their current thyroid issues. Micronutrient deficiencies can manifest in various ways, often with subtle symptoms that may be overlooked or attributed to other causes. Some common signs include:
Fatigue and Weakness
Often associated with iron or vitamin B12 deficiency, persistent tiredness and weakness can significantly impact daily life. Iron deficiency anaemia, in particular, can cause extreme fatigue, shortness of breath, and difficulty concentrating.
Brittle Hair and Nails
A lack of biotin, iron, or zinc can lead to weak, brittle nails and hair loss. These symptoms are often dismissed as cosmetic issues, but they can be indicators of underlying nutritional deficiencies.
Mouth Issues
Cracks at the corners of the mouth or a swollen, sore tongue may indicate B vitamin deficiencies, particularly riboflavin (B2), niacin (B3), pyridoxine (B6), and cobalamin (B12). These symptoms can make eating and speaking uncomfortable and may lead to secondary infections.
Poor Night Vision
Difficulty seeing in low light can be a sign of vitamin A deficiency. This deficiency can progress to more severe eye problems if left untreated, including xerophthalmia, a condition that can lead to blindness.
Slow Wound Healing
Inadequate vitamin C or zinc intake can impair the body’s ability to heal wounds. This can be particularly problematic for individuals with chronic conditions like diabetes, where wound healing is already compromised.
Bone Pain
Vitamin D deficiency can cause bone pain and increase the risk of fractures. This is particularly concerning for older adults, who are already at higher risk for osteoporosis and falls.
Muscle Cramps
Frequent muscle cramps, especially in the legs, can be a sign of deficiencies in minerals like magnesium, calcium, and potassium.
Mood Changes
Deficiencies in certain B vitamins, particularly folate and B12, have been linked to depression and other mood disorders. Omega-3 fatty acid deficiency has also been associated with an increased risk of depression and anxiety.
Dry, Scaly Skin
This can be a sign of vitamin A, vitamin D, or essential fatty acid deficiencies. In severe cases, it can lead to more serious skin conditions and increased susceptibility to infections.

The Importance of Nutrient Density
Instead of fixating on counting macros and calories or macronutrient ratios, try and prioritize nutrient-dense foods that provide a wide array of micronutrients. Nutrient density refers to the concentration of micronutrients relative to the energy content of a food. Foods with high nutrient density include:
– Leafy green vegetables (spinach, kale, collard greens)
– Colorful fruits and vegetables (berries, citrus fruits, bell peppers)
– Whole grains (quinoa, brown rice, oats)
– Quality proteins (fish, poultry and lean cuts of red meat in moderation)
– Nuts and seeds (almonds, chia seeds, flaxseeds)
– Legumes (lentils, chickpeas, black beans)
By focusing on these nutrient-dense foods, we can ensure a higher intake of essential micronutrients while still managing overall calorie consumption. To ensure adequate micronutrient intake while managing calorie consumption, consider the following approaches:
Eat a Rainbow
Consuming a variety of colourful fruits and vegetables is a key strategy for obtaining a wide range of essential vitamins and minerals, often referred to as “eating the rainbow,” based on the principle that different colours in produce indicate different nutrient profiles. Red-coloured fruits and vegetables are rich in antioxidants and beneficial compounds like lycopene, anthocyanins, and vitamin C, which may help reduce cancer risk, support heart health, and boost immune function. Orange and yellow produce are typically high in carotenoids such as beta-carotene, vitamin C, and flavonoids, supporting eye health, immune function, and reducing inflammation. Green fruits and vegetables are packed with chlorophyll and other beneficial compounds like folate, lutein, zeaxanthin, and glucosinolates, which are crucial for cell growth and health and may have cancer-fighting properties. Blue and purple foods are rich in powerful antioxidants including anthocyanins, resveratrol, and vitamin K, offering anti-inflammatory, neuroprotective, and heart-protective effects. White and brown fruits and vegetables, while not as vibrant, still offer unique nutritional benefits such as allicin, quercetin, and potassium, supporting heart health and providing anti-inflammatory effects.
Choose Whole Foods
Opting for minimally processed foods that retain their natural nutrient content is a key strategy for maintaining optimal health, as whole foods are generally richer in micronutrients compared to their processed counterparts. Minimally processed foods undergo little or no processing and retain most of their original nutritional value, making them an excellent choice for a balanced diet. For example, a whole apple contains more fiber, vitamins, and minerals than applesauce or apple juice. Similarly, brown rice retains its bran and germ layers, providing more nutrients than white rice, which has been stripped of these nutrient-rich components. By prioritizing whole, minimally processed foods, you ensure a higher intake of essential vitamins, minerals, antioxidants, and fiber, which can contribute to better overall health, improved digestion, and reduced risk of chronic diseases.
Balance Your Plate
Include a mix of proteins, complex carbohydrates, healthy fats, and plenty of vegetables in each meal. By combining these elements in each meal, you create a synergistic effect where nutrients work together for optimal absorption and utilization. For instance, vitamin C from vegetables enhances iron absorption from plant-based proteins, while healthy fats aid in the absorption of fat-soluble vitamins from leafy greens. This balanced approach not only ensures a diverse nutrient intake but also helps maintain stable blood sugar levels, promotes satiety, and supports long-term health and weight management.
Limit Nutrient Depleting Habits
Excessive alcohol consumption
Interferes with nutrient absorption and metabolism in several ways. It can damage the lining of the stomach and intestines, reducing the body’s ability to absorb nutrients. Alcohol also impairs the liver’s ability to store vitamins and minerals, particularly depleting B vitamins, vitamin A, vitamin C, vitamin D, vitamin K, and minerals like zinc, magnesium, and calcium. Chronic alcohol use can lead to thiamine (vitamin B1) deficiency, which can cause serious neurological problems.
Smoking
Another habit that significantly impacts nutrient status. It increases the body’s need for vitamin C, as smokers typically have lower levels of this vital antioxidant. Smoking also reduces the absorption of calcium and vitamin D, increasing the risk of osteoporosis. Beta-carotene, vitamin E, and other antioxidants are depleted more quickly in smokers, potentially increasing the risk of oxidative stress and related health issues. Additionally, smoking can interfere with the metabolism of folate, a crucial B vitamin for cell division and DNA synthesis.
Chronic stress
Prolonged stress increases the body’s demand for certain nutrients, particularly B vitamins, vitamin C, magnesium, and zinc. These nutrients are crucial for supporting the adrenal glands and maintaining a healthy stress response. Chronic stress can also impair digestion and nutrient absorption, potentially leading to deficiencies even when consuming a balanced diet. Furthermore, stress often leads to poor dietary choices and disrupted eating patterns, further compromising nutrient intake.
