What is the Best Diet?
Why the Best Diet is Probably Not What You Think
Ask a dozen different people what the best diet is and expect a dozen different answers. Some think it's all about eating more vegetables. Others think it's about cutting carbs. Others think it's about more protein. And they can all be right, for different people, at different times.
The truth is that the best diet varies from person to person. Age, activity level, health conditions and personal goals all play a significant role. Before anything else, let's clear up what the word diet actually means. A diet is simply the food a person usually consumes on a daily basis. It's not a temporary programme. It's just how you eat.
When looking at your diet, two questions are worth asking. Does my current way of eating promote my overall wellbeing or negatively impact my health? And what specific goals do I have for my dietary choices?
What does the best diet actually need to accomplish?
Regardless of which specific approach you follow, the best diet needs to do four things simultaneously.
1. Provide adequate nutrition
A good diet provides all the necessary nutrients, vitamins and minerals your body needs to function properly. This includes a balance of macronutrients, carbohydrates, proteins and fats, as well as the full range of vitamins and minerals. Without this foundation, everything else suffers.
2. Promote overall health
The best diet supports cardiovascular health, regulates blood sugar levels, promotes good digestion and boosts the immune system. If your way of eating is undermining any of these, it's worth reassessing.
3. Suit your individual needs and preferences
The best diet is one you can sustain long term. It should fit your personal taste, cultural background, dietary restrictions and lifestyle. A diet that works on paper but makes you miserable in practice is not the best diet for you. The Mediterranean approach I follow works because I genuinely love the food. That's not a small thing. That's everything.
4. Support your performance
Whether you want more daily energy, better performance in the gym or simply to feel sharper and more capable, the right diet makes a measurable difference. If your way of eating leaves you tired and flat, it's not doing its job.
What do most good diets have in common?
Whether you follow a Mediterranean, low-carb, plant-based, Paleo or omnivorous approach, well-structured diets share the same core behaviours when done properly.
They raise nutritional awareness
Any structured approach to eating makes you more aware of what you're consuming and how it affects your health. This awareness itself is valuable, independent of which specific foods you're choosing.
They focus on food quality
Good diets encourage whole, minimally processed foods. They discourage highly processed foods high in added sugars, unhealthy fats and artificial ingredients. The specific approved foods vary. The underlying principle doesn't.
They eliminate nutritional deficiencies
By promoting a balanced intake of nutrient-rich foods, good diets help ensure you're getting what your body actually needs rather than filling calories with nutritionally empty options.
They control appetite and food intake
High-fibre and protein-rich foods create satiety. Mindful eating reduces mindless consumption. Meal planning prevents impulse choices. These mechanisms work regardless of the specific dietary label you apply.
They promote regular movement
When people start eating better, they naturally start thinking about being more physically active. Good nutrition and regular exercise reinforce each other. They belong together.
So what is the best diet for you?
The best diet is balanced, varied, sustainable and genuinely enjoyable while meeting your individual nutritional needs. For me, the Mediterranean approach has been the answer my whole life. Real food, whole grains, legumes, fish, olive oil, vegetables, fruit and yes, dessert after dinner every night. It fits my Italian roots and my body's response to food perfectly.
But I'd never tell someone that's the only answer. The best diet for you is the one that makes you feel genuinely good, that you can imagine eating for the rest of your life and that produces the results you're after without making you miserable.

About Me
I'm Marco Asnicar, personal trainer, nutrition coach and founder of Vitality Marco. I didn't discover the Mediterranean method. I grew up living it, shaped by Italian roots, real food and movement as a natural part of daily life. It took me until recently to realise that what always felt completely normal to me is exactly what most people spend years searching for.
I coach men and women aged 35 to 55 to do the same. No restriction. No fads. No giving up the life you love. Just a way of eating and living that genuinely feels good and gets better every year.
