What does it mean to support metabolism, and why is it important?
Supporting metabolism refers to all the strategies used to optimize the biochemical processes through which the body converts nutrients into energy, regulates body weight, and ensures cell renewal. Metabolism is divided into two complementary phases:anabolism (tissue building and repair—which consumes energy) and catabolism (the breakdown of molecules—which releases energy). Metabolic support supplements are available in the store’s vitamins and minerals section.
- Basal Metabolic Rate (BMR): energy expended at rest to maintain vital functions—accounts for 60–70% of total energy expenditure—main determinant: muscle mass (muscle consumes 3 times more energy than adipose tissue at rest)
- Factors affecting metabolism: age (sarcopenic muscle loss after age 30 → BM ↓) — thyroid (T3 activates mitochondrial metabolism—hypothyroidism = overall slowdown) — sex (men have a BM 5–10% higher than women) — genetics — diet — physical activity
- Signs of a slowed metabolism: persistent fatigue — unexplained weight gain — sensitivity to cold — slow digestion — brittle hair and nails → thyroid evaluation recommended if multiple signs are present (consult a doctor)
- See the detailed biochemical mechanisms on the energy metabolism page
What practical steps can you take to support your metabolism on a daily basis?
- Thermogenic diet: protein (thermic effect: 20–30% of calories consumed vs. 5–10% for carbohydrates) — meal timing (3 regular meals — avoid prolonged fasting, which reduces basal metabolic rate) — soluble fiber (oats, legumes—slow glucose absorption, support the microbiome)—water (hydration is a cofactor in all enzymatic reactions—1.5 to 2 L/day)
- Physical activity: strength training 2 to 3 times per week — increases muscle mass → sustainably high BMR — EPOC (excess post-exercise oxygen consumption) — cardio 150 min/week (WHO) — avoid prolonged inactivity (take active breaks every hour)
- Sleep: 7 to 9 hours per night — lack of sleep disrupts leptin (decreased satiety), increases ghrelin (increased appetite), reduces insulin sensitivity and mitochondrial basal metabolic rate (BMR) — regular bedtime and wake-up schedule (circadian rhythm)
- Stress management: Chronic cortisol promotes muscle catabolism, abdominal fat storage, and inhibits digestion—cardiac coherence, meditation, yoga—seeglycemic balance
- Gut microbiome: Gut bacteria influence energy extraction from food and the production of appetite hormones (GLP-1, PYY) — prebiotic fiber + fermented foods (yogurt, kefir, sauerkraut) — see probiotics
What natural supplements support metabolism?
- Green tea (EGCG extract + caffeine): mild, documented thermogenic effect — increases energy expenditure by 3 to 5% over 24 hours — antioxidant — 300 to 400 mg/day of standardized extract — avoid in the evening (caffeine content)
- Chromium (picolinate): improves insulin sensitivity — stabilizes blood sugar levels — reduces post-meal cravings — 200 to 400 µg/day — use with caution in cases of treated diabetes
- Magnesium: cofactor for over 300 metabolic enzymes — common deficiency (stress, refined grains) — 300 to 400 mg/day bisglycinate — fatigue + cramps = signs of deficiency
- Probiotics: support the gut microbiome — influence fat and carbohydrate metabolism — take as a 4- to 8-week course
- These supplements support a healthy lifestyle — they are not a substitute for a balanced diet or regular physical activity
