For decades, people have struggled with fatigue and energy crashes, often without understanding why. One major culprit? The outdated nutrition advice that dominated the 1990s. The government’s food pyramid promoted a high-carb, low-fat diet that left many feeling sluggish and drained. Even though this guidance has since changed, its effects still linger in the way people eat today. To maintain steady energy, it’s crucial to understand how diet affects the body. The key lies in choosing the right balance of nutrients, particularly healthy fats and proteins, while avoiding the overconsumption of refined carbohydrates. By recognizing past mistakes, you can adjust your eating habits and improve your daily energy levels.
A Food Pyramid That Led Us Astray
The 1990s brought plenty of questionable trends. While we’ve left frosted tips and ultra-baggy jeans behind, one food habit remains. The 1992 food pyramid changed how people ate, but not for the better. It shaped public perception of nutrition in ways that still impact us today. The U.S. government introduced this guide based on Sweden’s 1970s model. It recommended six to 11 daily servings of bread, cereal, rice, and pasta. Vegetables, fruit, dairy, and protein followed, with fats and sweets at the top, labeled as “use sparingly.” This emphasis on carbohydrates led many to avoid fat, which we now know is essential for steady energy levels. Over time, the low-fat movement took hold, encouraging people to choose processed foods marketed as “fat-free,” even when they were high in sugar. This shift in eating habits had unintended consequences. Many people unknowingly set themselves up for energy crashes, weight gain, and long-term health issues. The pyramid’s recommendations lasted until 2005, meaning an entire generation grew up thinking that fat was bad and carbohydrates were the foundation of a healthy diet.

Why Low-Fat Diets Sap Your Energy
Dr. Michael Aziz, a physician and author of The Ageless Revolution, explains the problem. Cutting fat led people to rely on refined carbs, which cause energy crashes. While carbohydrates provide a quick source of fuel, they also cause spikes in blood sugar, followed by sudden drops that leave you feeling drained and sluggish.
Too much sugar and processed carbohydrates create quick energy spikes followed by rapid drops. When this happens repeatedly, it can lead to insulin resistance, weight gain, and constant fatigue. “You want steady energy all day,” Dr. Aziz told The Post. “To do that, you need more protein and healthy fats.” Without these essential nutrients, your body struggles to maintain stable blood sugar levels, making it harder to stay energized throughout the day. Nuts, seeds, olive oil, and avocados help stabilize energy. These foods provide long-lasting fuel, keeping you feeling full and focused for longer periods. Studies even show that eating fat before exercise improves endurance. Unlike refined carbs, healthy fats sustain your energy without causing crashes. After a workout, consuming carbohydrates like bananas can help replenish energy levels and support muscle recovery.
Not All Fats Are the Same
The original food pyramid grouped all fats together, but that was misleading. Saturated fat can raise cholesterol, increasing heart disease risk. However, monounsaturated and polyunsaturated fats—found in nuts, seeds, and fish—are beneficial. These healthy fats support brain function, heart health, and sustained energy. Experts criticized the pyramid early on. Dr. Walter Willett told Frontline in 2004, “It assumes all fat is bad, so carbs must be good. That’s not backed by science.” This flawed thinking led to decades of confusion about what a balanced diet should look like. Instead of recognizing the differences between healthy and unhealthy fats, the pyramid lumped them all into the same category, discouraging people from consuming essential nutrients. The guidelines were updated in 2005, but Harvard nutrition expert Dr. David Ludwig believes the damage was done. “The low-fat diet remains deeply embedded in public consciousness and food policy,” he wrote for CNN. Even today, many people hesitate to eat foods like nuts, avocados, and olive oil because they fear dietary fat will lead to weight gain. In reality, cutting out healthy fats can do more harm than good.
How to Regain Steady Energy
Balancing your diet is the best way to avoid energy crashes. Instead of relying on carbohydrates for fuel, focus on getting enough protein and healthy fats. These nutrients help stabilize blood sugar, providing a steady supply of energy throughout the day. Protein-rich foods like eggs, chicken, fish, and legumes keep you full and support muscle function. Healthy fats from sources like olive oil, nuts, and avocados enhance brain function and provide long-lasting energy. Including these foods in every meal can prevent the spikes and crashes caused by a carb-heavy diet.
Vitamin D can also help, especially in winter when sunlight is limited. Many people experience lower energy levels in colder months due to reduced sun exposure. Taking a vitamin D supplement or eating vitamin D-rich foods like salmon and fortified dairy can help maintain steady energy levels. Other useful supplements include vitamin B and CoQ10, both of which support cellular energy production. Moderate caffeine intake from coffee or green tea can boost alertness—as long as you don’t overdo it. While caffeine provides a temporary energy boost, too much can lead to jitters and energy crashes. The key is to balance your diet with nutrient-dense foods that fuel your body consistently.
Outdated Advice From the 90s
The outdated advice of the 1990s left a lasting impact on how people approach food and nutrition. While the food pyramid encouraged a high-carb, low-fat diet, science has since shown that healthy fats are essential for energy and overall well-being. Avoiding fat and overloading on processed carbohydrates leads to energy crashes, fatigue, and long-term health issues.
Final Thought
By shifting to a balanced diet rich in healthy fats, protein, and essential nutrients, you can regain control over your energy levels. Small changes in your daily eating habits can make a big difference. Fueling your body with the right foods will help you feel more energized, focused, and ready to take on the day. It’s never too late to break free from outdated nutrition myths and adopt a diet that truly supports your health and well-being.
