What Is the Alkaline Diet?
The alkaline diet is a nutritional system claiming that food can affect the body's acid-base balance (pH). According to this theory, modern diets are too "acidifying," which causes chronic inflammation, osteoporosis, fatigue and other diseases. The alkaline diet aims to balance pH by consuming 70-80% alkaline and 20-30% acidic foods.
Important: The human body has very effective pH regulation mechanisms (lungs, kidneys) — blood pH always remains within 7,35-7,45 regardless of diet. However, diet can affect urine pH and bone mineral density in the long term.
🧬 Key Principles
- 70-80% alkaline foods: vegetables (especially leafy greens), fruits, nuts, seeds
- 20-30% acidic foods: meat, fish, eggs, grains, dairy products
- Completely Avoid: processed food, sugar, coffee, alcohol, carbonated drinks
- Plenty of Water: it is recommended to drink alkaline water or water with lemon
- Plenty of Raw Food: raw salads, freshly squeezed juices, smoothies
🏋️ Pros and Cons for Athletes
✅ Pros:
- Plenty of Vegetables and Fruits: ensures an abundance of vitamins, minerals, antioxidants
- Less Processed Food: the amount of added sugar and salt automatically decreases
- Hydration: encourages drinking plenty of water, which is important for athletes
- Bone Health: a lot of potassium and magnesium from vegetables may help preserve bone density
❌ Cons:
- Protein Deficiency: only 20-30% acidic foods means protein may be too low for muscle growth
- Weak Scientific Basis: the body regulates pH itself; the influence of diet is minimal
- Carbohydrate deficit: athletes may lack energy without a sufficient amount of grains
- B-Group Vitamin and Iron Deficiency: when limiting animal products, supplements are needed

💡 Practical Everyday Tips
📝 Monitor and Adjust
Keep a food diary for at least 2 weeks. What works for your body is individual. Review the results every month and adjust your strategy.
⏰ Consistency — More Important Than Perfection
Better 80% optimal nutrition every day than 100% one week and 50% the next. Consistency is the key to long-term results.
🔬 Individual Differences
What works for your training partner will not necessarily work for you. Genetics, microbiota, hormones — everything is individual.
📊 Measure Progress
Do not rely on the scale alone. Measure body circumferences, track strength indicators, and take progress photos every 4 weeks.
