A common myth is that having an MTHFR variant (e.g., C677T) directly prevents weight loss or requires a special diet. In reality, MTHFR influences folate and homocysteine metabolism, but a causal link to weight loss is not established. Weight loss is multifactorial: calorie balance, exercise, hormones, gut microbiome, and psychological factors play far larger roles than a single gene. Some studies show associations between MTHFR polymorphisms and obesity, but effect sizes are small and inconsistent. The idea that methylfolate supplementation alone promotes weight loss is not scientifically supported. Such supplementation is only indicated for elevated homocysteine or specific clinical conditions – not for weight reduction. Those aiming to lose weight should focus on a balanced diet, regular physical activity, and a healthy lifestyle rather than fixating on individual gene variants.

The reality: the effect sizes of these variants on basal metabolic rate or fat oxidation are very small and are dwarfed by lifestyle, diet, and physical activity.

These variants can raise homocysteine levels, which have been linked to recurrent pregnancy loss. However, the clinical utility of genetic testing is limited: homocysteine can be measured directly, and the treatment (folic acid, B12, B6) is the same regardless of genotype. Many other factors (age, hormones, lifestyle) are more critical. The evidence for a causal role of MTHFR in fertility is moderate, but marketing exaggerates it. **Bottom line:** Both test categories are more marketing than evidence-based medicine.
