Oefeningen bij leververvetting (NAFLD/MASLD) — 20-30% vetreductie

Non-alcoholic fatty liver disease (NAFLD, now renamed MASLD — metabolic dysfunction-associated steatotic liver disease) affects roughly 25% of US adults and is the leading liver disease globally. The 2017 Romero-Gomez review and the 2024 EASL-EASD-EASO clinical practice guidelines both confirm that exercise improves liver fat content independent of weight loss. Specifically: 150-200 minutes per week of moderate aerobic exercise plus 2-3 days of resistance training reduces intrahepatic fat by 20-30%, even when body weight stays stable. Add 7-10% body weight reduction (achievable in 6-12 months with combined diet + exercise) and you induce histological NASH remission in 40-50% of patients — a clinically meaningful outcome. The mechanism is multiple: improved insulin sensitivity (reduces de novo lipogenesis), increased peripheral fatty-acid oxidation, reduced visceral adiposity, and reduced systemic inflammation. Combined intervention (diet + exercise) outperforms either alone in every head-to-head trial.

Volya's catalogue carries the foundation: slow-arm-swing-walk and standing-march for the aerobic protocol that drives the 20-30% liver-fat reduction, wall-push-up for upper body, supported-glute-bridge for joint-friendly glute work, sit-to-stand and single-leg-stance for functional strength + balance, scapular-retraction for posture. The AI coach also knows the nutrition side — Mediterranean pattern is the strongest evidence (Ryan 2013 RCT improves liver fat independent of weight loss), AVOID added fructose (corn syrup, sweetened beverages — directly drives de novo lipogenesis), AVOID alcohol (accelerates fibrosis even at moderate doses in NAFLD), omega-3 1-2 g/day (algae for vegans), vitamin E 800 IU/day shows histologic improvement in non-diabetic NASH (PIVENS trial — discuss with hepatology before starting; contraindicated in some cardiac users), coffee 2-3 cups/day associated with reduced fibrosis, carb shaping 30-50 g/meal paired with protein + fibre + fat. This is NEVER a replacement for hepatology management — work with your specialist.
