What is food and why do we eat?
You've heard the phrase "you are what you eat." Let's expand that: we are what we digest, absorb, and utilize through our body's cells. That's why food quality matters immensely.
Food is made up of macronutrients (proteins, carbohydrates, fats), micronutrients (vitamins, minerals, phytonutrients), and water. These nutrients are crucial for our physiological needs. The type of food (its quality) directly impacts how we feel, our health, and our body composition, which in turn influences our overall lifestyle and well-being.
We eat to sustain the complex human system. How we eat matters for our quality of life because food is not just fuel; it's information.
Eating habits - yes, "diets" - no
In our team, we don't favor the term "diet." It's not because it's wrong, but because it often leads beginners down the wrong path. A "diet" implies a start and an end—something you begin on Monday and quit after 30 days for a beach trip or an event.
This mindset is a trap. People often think, "It's only 30 days, I'll just suffer through it," make poor choices, fail to reach their goals, and end up feeling worse than before.
Instead, let's talk about eating—a way of nourishing yourself that has no end date. It's a style of eating that allows you to achieve your goals, feel good in your body, provide all necessary nutrients for optimal function, and bring you pleasure—not discomfort.
Before what to eat, learn how to eat
If you could make just one change to your eating habits right now, let it be this: eat slowly and mindfully.
What does this mean?
Chew your food thoroughly.
Don't rush through your plate.
Eat, whenever possible, in a calm environment.
The benefits are profound:
Improves digestion and hydration.
Reduces bloating.
Can prevent poor choices linked to disordered eating patterns.
Allows satiety signals to reach your brain, preventing overeating.
Aids in weight management.
Increases pleasure and enjoyment from food.
Planning your meals around your daily needs and realities
Before planning your meals, remember this golden rule: there is no universal eating schedule that works for everyone.
Forget the "must-dos" you've seen: "you must eat breakfast," "don't eat after 6 PM," "eat small, frequent meals." Focus on your own needs and possibilities.
Consider these factors:
How many times a day can you eat? Maybe you don't have time for breakfast or don't feel good eating it. Perhaps your work is irregular or shift-based. It doesn't matter how many times you eat per day to reach your goals, as long as other factors (discussed below) are in place.
What is your physical activity level? Plan your food around your movement. A highly active lifestyle with intense training may require more food, larger portions, or more frequent meals. A more sedentary lifestyle might feel better with fewer meals. There's no formula—learn to listen to your body's signals.
Do you eat alone or with others (family, partner)? Cooking for others, eating with people who have different habits, or wanting family dinners at specific times all influence your planning.
The main takeaway: There is no universal regime. You can always organize your eating around your daily life.
How to stay in control when your plan falls apart
Having a plan provides security and comfort. But sometimes, Plan A fails due to unforeseen circumstances, other commitments, or a cascade of events.
In such cases, you might need to compromise—eat something that's not the optimal choice, skip a meal, or activate Plan B (like finding a nearby store or restaurant).
Remember: Nothing fatal has happened. You won't ruin all your progress unless you let it spiral by thinking, "I've already messed up my routine, I might as well give up..."
If you make good food choices and maintain healthy habits most of the time, occasional off-plan meals will not derail your results.
Practical tips for a derailed plan:
Choose the lesser evil: A sandwich with meat and veggies over a hot dog with fries; plain yogurt and nuts from a store over ice cream and chips.
Don't overeat: Don't trick yourself with the thought, "I've already ruined it, I might as have more."
Still eat slowly and calmly.
Wait it out: If you can hold off until you find a better option, do so.
Don't blame yourself even if Plan B fails.
Focus on foods, not just calories
When talking about food, most people think first of calories, then protein, carbs, and fats. But first and foremost, we eat food. It matters where our calories come from if we want to feel good, energetic, healthy, and achieve our goals.
Your menu should predominantly feature whole, unprocessed foods: meat, fish, eggs, vegetables, fruits, seeds, nuts, unrefined fats, whole grains, and water.
Minimize sugar, trans fats, refined products, canned foods, and ready meals.
Key guidelines for a beginner:
Include a protein source with every meal (animal or plant-based).
Eat vegetables with every meal—colorful, seasonal, preferably raw.
Eat larger portions of carbs (rice, potatoes, whole grains) when you've earned them—after a workout or a day of high physical activity.
Include healthy fats: saturated (butter, coconut oil), polyunsaturated (fish oil, nuts, flaxseed oil), and monounsaturated (nuts, olive oil, olives).
Follow the 80/20 or 90/10 rule: Let 80-90% of your food be nutrient-dense, unprocessed, fresh, and free from added sugar and trans fats. The remaining 10-20% can be for those less-nutritious foods you simply enjoy.
Choosing foods, planning menus, and budgeting
As mentioned, there's no universal diet. Let your food choices be guided by personal preference, budget, and storage options.
Base your menu on nutrient-rich foods. Make a list of your favorite protein, fat, and carb sources that you enjoy eating. Add your preferred vegetables and spices. You now have a core shopping list.
Research market prices to see if your desired foods fit your monthly budget. You don't need expensive "superfoods" to succeed or feel good. This can be achieved with well-known, local products.
Consider how often you can shop per week (once, twice, more). This will determine what you buy and how you store it (fridge, pantry).
Eating at home vs. eating out: If you can balance it so that most of your food is home-cooked, you'll reap many benefits: better control over ingredients, alignment with personal taste, always fresh food, cost savings, and the pleasure of cooking. It's never too late to start cooking—with good organization and a plan, it doesn't have to be time-consuming.
Water and daily fluid needs
Water is vital—about 60% of our body weight is water. It has crucial functions: transportation, participation in chemical reactions, joint lubrication, body temperature regulation, protection, and as a source of minerals.
Your fluid needs depend on body weight, composition, physical activity, and environmental temperature. We get fluids from both water and food (mainly fruits and vegetables).
You can determine your needs in two ways:
Consume 30-40 ml of water per kilogram of body weight. If you weigh 60 kg, that's 1.8 - 2.4 liters per day.
For every 100 kcal of your Basal Metabolic Rate (BMR), aim for 80-110 ml of fluids.
Remember to adjust for physical activity and hot weather.
The goal is optimal hydration—avoiding both dehydration and excessive water intake that could dilute sodium levels (hyponatremia).
And yet, her majesty - the calorie!
We said we eat foods, not calories, but that doesn't mean calories are unimportant. Caloric balance is not a myth; it determines whether you lose, gain, or maintain weight.
Calories In > Calories Out = Weight Gain
Calories In < Calories Out = Weight Loss
Calories In = Calories Out = Weight Maintenance
While formulas exist to determine your personal caloric needs, they are not 100% accurate due to factors like gut flora, food preparation, inaccuracies in labeling, and the non-digestible fiber in your food.
Therefore, it's important to understand: you can count calories, but you can't perfectly predict real-life outcomes. It's more valuable to observe yourself and make adjustments along the way.
An alternative way to measure food (our recommendation)
For a beginner, counting calories can often become a stumbling block, causing frustration and resentment towards building better habits.
If that sounds like you, we recommend an intuitive, simple alternative: the hand-portion method.
All you need are your hands:
Your palm determines your protein portion.
Your fist determines your vegetable portion.
Your cupped hand determines your carbohydrate portion.
Your thumb determines your fat portion.
The thickness and diameter of the food (in its cooked state) should be roughly equivalent to the size of your palm and fist. The "palm" measurement does not include your fingers.
Macronutrient distribution template
For Women (per meal):
Protein: 1 palm
Vegetables: 1-2 fists
Carbs: 1 cupped hand
Fats: 1 thumb
For Men (per meal):
Protein: 2 palms
Vegetables: 1-2 fists
Carbs: 2 cupped hands
Fats: 2 thumbs
*For liquid fats (like olive oil), use a tablespoon as a guide: about 1 tbsp for women and 1.5-2 tbsp for men per meal.*
How many such portions per day?
Again, it's individual. However, using the hand-portion method, 4 such portions per day is a good starting point and frame of reference (but not a mandatory or only option).
Eating with health limitations / obstacles
If you have food allergies, a specific medical condition, or digestive issues that require a special approach to food selection and preparation, always consult your doctor or a registered dietitian. Plan your nutrition according to the recommendations of your healthcare specialist.
Start your journey by focusing on how you eat, choosing whole foods, and listening to your body. Build sustainable habits, not temporary restrictions. That is the true path to lasting well-being.
