impact of portion sizes – Crisbie Coach

Human life has transformed dramatically in the last century. We’ve moved from agrarian societies, where physical labor and homegrown food were central to existence, to urban environments dominated by convenience, speed, and processed meals. Along the way, our diets and lifestyles have shifted in ways that have quietly but powerfully contributed to the modern epidemics of overweight and obesity.

The Social and Cultural Shifts Behind the Crisis

Picture life a few decades ago: meals cooked from scratch, family dinners without distractions, and a pace of life that allowed time to prepare, eat, and enjoy food. Now, compare that to today’s way of eating. We rush through meals, rely on takeout, and often consume food in front of screens. These cultural shifts, coupled with the marketing of calorie-dense, nutrient-poor foods, have rewired our relationship with eating.

Portion sizes have ballooned, and processed foods‘ affordability often outweighs the fresh produce cost. Moreover, technological advancements have reduced the physical effort required in daily life, leaving us more sedentary than ever. Together, these factors create a perfect storm for rising obesity rates.

The Role of Nutrients in Our Diets

To understand how to support your health, we must first unpack the essential nutrients in our foods and their roles:

Carbohydrates provide energy, but not all carbs are equal. Refined carbs like white bread and sugary snacks spike blood sugar levels, while complex carbs found in whole grains and vegetables release energy slowly, sustaining us throughout the day.
Proteins are the building blocks of life, repairing tissues and supporting muscle growth. Lean sources like beans, lentils, eggs, offer high nutritional value with minimal environmental impact.
Fats are essential for brain health and energy, yet there’s a big difference between healthy fats from nuts, avocados, and olive oil, and harmful trans fats found in fried and processed foods.
Vitamins and minerals support countless bodily functions, from immune defense to bone health. Consuming a colorful variety of fruits and vegetables ensures we get a spectrum of these critical nutrients.

Choosing Wisely Without Harming the Planet

Our food choices influence not only our health but also the health of the planet. Animal agriculture, for instance, is a leading contributor to greenhouse gas emissions. We can lighten our environmental footprint by choosing plant-based proteins, reducing meat consumption, and opting for sustainably sourced seafood.

Consider these actionable strategies:

Prioritize whole foods: Fresh, unprocessed foods retain their nutrients and avoid the hidden sugars, sodium, and unhealthy fats lurking in packaged meals.
Diversify your plate: A mix of grains, legumes, vegetables, and fruits not only supports health but reduces reliance on resource-intensive food sources.
Practice portion mindfulness: The principle of eating until you’re satisfied, not full, aligns with many traditional eating cultures and can help combat overconsumption.

Reflecting on the Path Forward

The battle against obesity isn’t won with diets or quick fixes. It requires a collective reevaluation of how we view food, not just as fuel but as a cultural and environmental keystone. By choosing foods rich in nutrients and grown sustainably, we honor our bodies and the earth.

Slow down to reconnect with food, it can be transformative. Cooking a simple, balanced meal, savoring each bite, and sharing it with loved ones remind us of the joys and health that food brings.

In many Eastern cultures, eating isn’t just about nourishing the body—it’s an art form rooted in respect for health, balance, and longevity. For example, the concept of hara hachi bu in Japan encourages eating until you’re around 80% full. Similarly, in China, eating until only 75% full is common, while in Korea, stopping at about two-thirds capacity is considered beneficial. This approach to moderation contrasts sharply with Western habits, where meals often end only when one feels “full.” Could this difference in mindset contribute to the obesity epidemic?

The Wisdom of Stopping Before Fullness

Eating with restraint—before reaching fullness—is a simple concept yet profound in its impact. In Japan, hara hachi bu is more than a saying; it’s a philosophy that encourages people to stay connected with their body’s signals, eating just enough to fuel their energy but not so much that they feel stuffed. Similarly, traditional Chinese and Korean dining practices align with an understanding that excessive fullness may disrupt harmony in the body.

This mindful moderation allows for digestion to happen more naturally, reduces the likelihood of overeating, and prevents the strain that an overloaded digestive system can create. By leaving space in the stomach, the body can process what it needs without feeling overwhelmed.

Western Habits: Why Do We Eat Until We’re Full?

In contrast, many Western cultures lack a strong cultural practice around moderate eating. Meals are often large and designed to fill us up rather than nourish us in measured amounts. In the West, eating habits are frequently driven by “value for money,” resulting in super-sized portions and a mindset of eating until full, sometimes even beyond.

The constant availability of processed and ultra-processed food, and calorie-dense makes it easy to forget what true satiety feels like. Social gatherings also play a role. Celebrations often revolve around food, where “enough” quickly becomes “too much.” Over time, our perception of “full” adjusts to larger portions, and the habit of overeating can become normal.

The Link Between Overeating and Obesity

It’s a well-known fact that the rate of obesity has been rising globally, with around 46% of the world’s population now classified as overweight or obese. In the West, where the practice of eating until full is most common, there is a direct correlation between portion sizes and obesity rates. When eating becomes disconnected from hunger and instead revolves around habit, emotion, or availability, the body is pushed beyond its natural limits.

Moderation, however, is not a denial of food. It’s a recognition of balance and respect for the body’s signals. Eating with restraint is about re-learning how to tune into these signals, a shift that can naturally help manage weight and prevent the issues associated with overeating.

How We Can Incorporate Moderation into Our Lives

Adopting the wisdom of hara hachi bu doesn’t require drastic change. Here are a few small steps that can help bring mindful eating practices to our daily routine:

Pause Mid-Meal: Take a moment halfway through your meal to assess your hunger. This small break helps prevent mindless eating.
Serve Smaller Portions in Smaller Dishes: Start with smaller portions, knowing you can always add more if you’re still hungry. Use also a smaller dish, so you can fill it up for the pleasure of your eyes.
Listen to Your Body: Pay attention to how food makes you feel. Eating slowly allows time for your brain to recognize fullness, often before the plate is empty.
Eat Not Just for Pleasure: Enjoying food is important, but focusing on how it fuels your body can help reframe how much and what you eat.

By adopting the art of moderation in eating, we align ourselves with our body’s needs rather than succumbing to habitual overeating. Eastern cultures’ approach to stopping before fullness shows how small, mindful practices can yield significant health benefits. Perhaps, by taking these lessons to heart, we can collectively contribute to healthier lifestyles.
