More and more people are struggling with digestive issues, low energy and a sense of imbalance in their daily lives. The topic of gut health is extremely relevant right now – it's at the centre of the conversation about our overall wellbeing. But what's really behind these problems, and what practical steps can we take?
In this article, we look for answers to key questions about nutrition, circadian rhythm and the everyday habits we often underestimate. If you're wondering how to make your life more balanced and mindful, keep reading.
We spoke about the topic with Stoyan Petkov – nutritionist, dietitian and founder of Agaia. He specialises in fitness and conditioning, sports recovery, and the analysis of metabolic and physiological markers. For Stoyan, nutrition isn't just about counting calories – it's a science, a philosophy and a way of life.
In this article you'll learn:
- which foods really support longevity;
- how chronic stress affects metabolism and eating habits;
- why circadian rhythm is key to health;
- how to navigate conflicting information and nutrition “trends.”
Longevity – Which Foods Support It?
According to Stoyan Petkov, over the next 10–15 years we'll see the rise of so-called functional dietetics, focused on prevention and long-term health rather than just quick results.
“We can't talk about longevity if the body isn't able to handle what we give it,” he explains. When a health issue is present, the focus should first be on recovery and improving overall health status.
Longevity Means:
- a well-functioning digestive system;
- efficient absorption of nutrients;
- a low chronic inflammatory and immune response;
- good oxidation and elimination of waste products.
When it comes to food, the emphasis is on:
- easily digestible, seasonal produce
- adequate hydration
- quality sleep
- additional micronutrients such as vitamins, minerals and antioxidants, when needed
The Importance of Circadian Rhythm
Circadian rhythm is one of the most underrated, yet most important factors for health. It's directly linked to the sun-moon cycle and covers the timing of sleep, eating, activity and rest.
“The body loves rhythm. There's no order in chaos,” says Stoyan.
To talk about longevity, we need to build a stable daily cycle:
- regular, adequate sleep
- a clear eating schedule
- a predictable routine
This natural rhythm has a far stronger long-term effect on health than relying solely on supplements or short-term strategies.
In a modern world full of diets and extreme regimens, what's the most important thing to know?
Right now, the most popular approaches are low-carb diets and short 21- or 25-day “challenges.” The reason is simple – restricting carbohydrates makes the body lose water, which leads to rapid weight loss.
“However, this isn't functional fat loss – it's mostly water loss,” Stoyan points out.
Real fat reduction is a process that takes time. Clinically monitored nutrition doesn't focus only on the scale, but on:
- what exactly the body is losing – water, fat or muscle mass
- what the long-term effects are
Extreme diets almost always lead to extremes and the yo-yo effect.
Which Foods Are Good for Preventing Digestive Problems?
Digestive problems are highly individual and can't be treated with a one-size-fits-all approach. In his practice, Stoyan works daily with people who have digestive disorders.
General recommendations include:
- avoiding ultra-processed foods – fried, breaded, overly heavy meals
- limiting the mixing of different types of protein
- simpler combinations on the plate
Heat-treated foods are often gentler on the digestive system, since the starch and fibre are already “prepared” for absorption.
Supportive foods include:
- fermented products
- enzyme-rich foods, such as kiwi
That said, it all depends on the person's starting point and individual condition. Avoiding liquid sugars is also key.
What Are the Signs That Our Microbiome Needs Attention?
Among the most common signs are:
- heaviness and bloating
- gurgling
- irregular or changeable bowel movements
- heartburn, burping
- skin reactions such as rashes
The body always gives signs – the question is whether we listen to them in time.
How Do We Prevent Emotional Eating?
Food is often linked to reward, comfort and positive emotions. From childhood, we associate it with celebration and pleasure.
“A systemic problem, however, can't be solved with unsystematic methods,” says Stoyan.
The key lies in building a stable rhythm and routine that nourishes the body, instead of using food to make up for an emotional deficit.
How Do We Choose the Right Information Instead of Just Following Trends?
Information in the field of nutrition is often contradictory – even in clinical trials. That's why one of the safest guiding principles is simplicity.
“Avoid ultra-processed foods and products with a long list of unfamiliar ingredients,” Stoyan advises.
The simpler and more natural the food, the greater the chance it's a good fit for your body.
What Role Do Supplements Play in a Balanced Routine?
Supplements can be a useful tool when tailored to individual needs and goals. It's important not to take them indiscriminately or rely on them as a substitute for core habits.
What Should You Remember From Stoyan?
Health starts from the inside out. The most important thing is to listen to your body's signals and not wait until the last moment, when the problem is already there. Prevention is always easier than treatment.
Be honest with yourself – about what isn't working, what needs to change, and how you can better support your body.
