Should You Snack? Exploring Healthy Snacking and Smarter Choices

Debunking the Myth: Do Smaller, More Frequent Meals Boost Metabolism?

For years, conventional nutritional advice has promoted the idea of eating 5-6 small meals throughout the day to boost metabolism and encourage fat loss. This theory suggested that frequent eating would “stoke the metabolic fire,” while infrequent meals would slow down metabolism and lead to fat storage. However, this approach overlooks what actually happens in the body with each snack or small meal.

Contrary to popular belief, there is no scientific evidence supporting the claim that smaller, more frequent meals offer any metabolic advantage. In fact, research indicates that the more often you eat, the more insulin your body releases. This constant output of insulin can disrupt blood sugar levels and lead to a rollercoaster of highs and lows, causing additional cravings, fat storage, mood changes, and irritability.

Each meal or snack triggers a rise in blood sugar followed by an insulin release. Consuming many small meals throughout the day can result in frequent blood sugar spikes, leading to energy crashes and increased hunger. Additionally, the process of digestion requires energy and time, diverting resources from other bodily repairs and tasks. Unused nutrients from these frequent meals are often stored as fat, preventing the body from utilizing stored fat between meals.

The goal should be to maintain steady blood sugar levels by consuming balanced meals with sufficient fat and protein to achieve satiety. Avoid relying on refined starchy carbs and sugars for quick energy. This approach supports a more stable metabolism and reduces the need for constant snacking.

Understanding Blood Sugar

Our bodies are designed to keep glucose levels in the bloodstream balanced through a complex monitoring system. When glucose levels rise, the pancreas releases insulin, which signals cells to absorb and store the excess glucose, preventing blood sugar from getting too high.

The ideal scenario is a consistent, gradual release of glucose from unrefined, whole food sources. This controlled release contrasts sharply with the sudden spikes caused by consuming sugary drinks, refined carbs like chips and popcorn, and sweets. Our bodies are not meant to rely solely on carbohydrates. Instead, we function best with a balanced intake of unrefined carbohydrates (such as fibre-rich vegetables and low-glycemic fruits), healthy fats, and quality proteins. This balance provides sustained energy and supports overall health.

Build a Fire

To understand how to structure your meals and plan your daily eating, think of your day as a large fire. This fire represents the energy you need to fuel your various activities and stay awake, alert, and highly functional. Carbohydrates act like kindling in this fire: dried sticks, leaves, and crumpled paper that burn quickly, providing short bursts of energy. Just like a fire fueled by kindling, you get a quick burst of energy, but it’s short-lived and soon followed by a crash, requiring more kindling to keep the fire going.

Instead of relying on small handfuls of kindling throughout the day (snacks), using a log would be more effective. Quality fats and proteins are like a big, solid log on your fire; they burn slowly and steadily, providing longer-lasting energy without the sharp drop-offs. Healthy fats and proteins offer a more sustained source of balanced energy and supply the body with the necessary precursors for creating healthy hormones.

This analogy simplifies the concept that exclusively burning carbs/glucose creates a blood sugar rollercoaster with dramatic highs and lows. This approach isn’t sustainable and leads to constantly seeking your next meal or snack. If fat loss is a goal, this method can make achieving it more challenging.

The Problem with Snacking

Whenever we eat, our blood sugar rises. The extent of this increase depends on the foods we consume, along with factors such as genetics and stress. As blood glucose levels rise, the pancreas releases insulin to transport the glucose to cells for energy.

Frequent snacking throughout the day causes continuous insulin release, which can lead to prolonged fat storage. Without constant blood glucose spikes from frequent snacks, the body is more likely to burn fat for fuel.

Additionally, continuous digestion requires energy, diverting it from other bodily functions. Constant eating prevents the body from taking breaks and using stored fat between meals.

When and How Often Should We Eat?

For most people, eating more frequently isn’t the key to fat loss or maintaining steady energy levels. In fact, the answer often lies in eating less frequently. Reducing or eliminating snacks can help give our systems a much-needed break between meals, avoiding the constant blood sugar rollercoaster.

I generally recommend three well-balanced meals a day (or two if you practice intermittent fasting and have good blood sugar control). These meals should focus on quality protein and fat, complex carbohydrates, and fiber from vegetables like leafy greens and broccoli. Prioritise a variety of colourful, nutrient-dense foods to ensure you’re getting essential micronutrients, vitamins, and minerals. The goal is to build meals that keep you satisfied and prevent sharp spikes in blood sugar.

Fat has the least impact on blood sugar and, when combined with a full meal, slows glucose absorption, helping to avoid large spikes. Protein also helps maintain steady blood sugar levels. While protein alone won’t cause a rise in blood sugar, excessive amounts can be converted to glucose through a process called gluconeogenesis.

Fibre-rich vegetables further slow glucose absorption. The fibre in whole vegetables or fruits that contain carbohydrates plays a crucial role in moderating blood sugar levels.

What to Snack On

Opt for snacks that are rich in protein and healthy fats while avoiding high-glycemic, refined carbohydrates. This approach helps you steer clear of blood sugar spikes and crashes.
