From fitness to the microbiome: The most effective approaches for an active metabolism

Key Takeaways

  1. Strength training and HIIT as metabolism boosters: Building muscle through strength training and intensive exercise phases in HIIT increase the basal metabolic rate and promote the afterburn effect for sustained calorie consumption.
  2. Protein-rich diet: Supports metabolism through thermogenic effects and fat burning.
  3. Intestinal health: A healthy microbiome improves nutrient absorption and lipid metabolism.
  4. Probiotics and prebiotics to support the microbiome: Fermented foods and fiber promote the growth of beneficial bacteria that regulate metabolic hormones and optimize energy production.
  5. Holistic approach for sustainable health: A combination of exercise, a balanced diet, intestinal care, sufficient sleep, and stress management ensures long-term metabolic optimization and greater well-being.


In a world characterized by prolonged sitting and lack of exercise, sport is becoming an important counterbalance for more and more people. But did you know that metabolism – the inner engine of your body – determines how effectively you burn calories, generate energy and regenerate?

A sluggish metabolism can hinder progress, while an active metabolism supports peak physical and mental performance. In addition to exercise, nutrition and gut health are also crucial to how well the body functions.


This article shows how metabolism can be effectively boosted through targeted training, proper nutrition, and improved intestinal health—for more energy, better performance, and lasting physical well-being.

Metabolism: Basics and Significance

To understand metabolism in all its complexity, it is worth first looking at the definition. metabolism, or also metabolism, encompasses all the biochemical processes that provide your body with energy and ensure its functionality. These processes are crucial not only for energy production, but also for the development and maintenance of tissue, hormone production, and the regulation of your immune system.

A well-regulated metabolism forms the basis for physical and mental performance. However, when metabolic processes falter, this often manifests itself in the form of lack of energy, weight gain, or even long-term health problems. This highlights the importance of actively working toward an efficient metabolism—and using holistic approaches.

Strategies to increase metabolism


Promoting an active metabolism requires sustainable habits that integrate exercise, diet and lifestyle.


For this, Freeletics The optimal support: Freeletics is an innovative fitness app that helps people achieve physical and mental goals – regardless of fitness level or schedule. With personalized digital coaching, the app enables workouts that can be done anywhere and without equipment, as well as programs that combine strength training and high-intensity interval training (HIIT). In addition to physical exercises, Freeletics emphasizes the importance of nutrition, mental strength, and recovery. This holistic approach not only promotes fitness but also helps integrate healthy habits into your daily life in the long term.With a strong community and scientifically sound methods, Freeletics offers a flexible, effective, and sustainable solution for personal fitness.


Freeletics' holistic approach is complemented by practical measures that can be easily integrated into everyday life to sustainably improve fitness and metabolism:

  1. Strength training for long-term effects
    Building muscle mass is one of the most effective ways to increase your basal metabolic rate. Muscles are metabolically active and burn more calories than fat tissue, even at rest. Regular strength training stabilizes your metabolism in the long term.
  2. High-intensity interval training (HIIT)
    HIIT combines intense exercise phases with short recovery intervals. Studies show that the afterburn effect increases calorie burn even hours after training, further boosting metabolism.
  3. The role of nutrition
    A protein-rich diet supports metabolism through the thermogenic effect of proteins, which require more energy for digestion. Healthy fats, such as omega-3 fatty acids, promote fat metabolism and have anti-inflammatory effects. Adequate water intake is also essential to support efficient metabolic processes.
  4. Sleep and stress management
    lack of sleep and stress negatively impact metabolism, especially through hormonal imbalances. Measures such as sufficient sleep, meditation, or breathing exercises help promote regeneration and stabilize hormone levels.

Intestinal health as the foundation for an active metabolism

In addition to exercise and nutrition, the gut is a central hub of metabolism. The microbiome—the entirety of microorganisms living in the gut—influences digestion, energy production, and even fat burning.


Intestine and metabolism: An inseparable connection


Trillions of microorganisms live in your digestive tract, which together form what is known as intestinal microbiome These microorganisms not only influence digestion but also the production of short-chain fatty acids (SCFAs), which have anti-inflammatory effects and improve insulin sensitivity. Studies* show that a healthy microbiome can increase fat burning, improve energy supply, and reduce inflammatory processes in the body.


Probiotics and prebiotics: How they boost your metabolism

  • Probiotics are live microorganisms that strengthen your intestinal flora and have anti-inflammatory effects. Certain bacterial strains such as Lactobacillus and Bifidobacterium promote fat burning and regulate metabolic hormones such as insulin and leptin.
  • Prebiotics provide the "food" for these beneficial bacteria. Fibers such as inulin or fructooligosaccharides promote the growth of the right microorganisms and support the formation of SCFAs, which activate metabolism.
  • Synbioticsthat combine probiotics and prebiotics maximize the effect and promote not only healthy digestion but also more efficient energy production.


By integrating fermented foods such as yogurt, sauerkraut, or kimchi and fiber-rich foods such as whole grain products, legumes, and vegetables, the microbiome can be naturally supported—and thus indirectly optimize metabolism.


Probiotic supplementation can also provide significant results in boosting metabolism. Dietbacs® mybacs® contains over 5 bacterial strains that are clinically proven to boost metabolism. They also contain Reducose®, a blood sugar-regulating extract from mulberry leaves. Together, they support blood sugar levels and metabolism and aid weight management.

An active metabolism and its health benefits


A healthy gut and an active metabolism offer numerous benefits:

  • More energy: An efficient metabolism ensures increased performance in everyday life.
  • Weight control: Fat burning is optimized, making it easier to maintain a healthy body weight.
  • Better regeneration: Stresses can be balanced more quickly.
  • Strong immune system: The body’s own defenses benefit from an active metabolism.

A holistic approach to your metabolism

Promoting an active metabolism is a long-term investment in your health. Through a combination of targeted exercise, a balanced diet, and maintaining your gut health, lasting improvements can be achieved.

It's important to be patient and integrate changes into your daily routine gradually. Start with small adjustments—like increasing your fiber intake or introducing short HIIT sessions—and build on them.

Ultimately, it's not just about optimizing your metabolism, but about promoting your holistic well-being. The transition should be viewed as a continuous process—with the goal of sustainably improving your health and quality of life.
