How to do it

Swap one refined grain (white bread/rice/pasta) for a whole-grain version

This is the evidence-based dose. A shorter session still counts, it just gives partial benefit rather than the full effect.

Common misconceptions

'Whole grains spike blood sugar the same as refined.' Their fiber blunts the response.
'Gluten-free is healthier.' Only necessary for celiac disease/sensitivity; many GF products are refined.
'All brown bread is whole grain.' Check for 'whole grain' as the first ingredient.

When to seek a professional

Signs of disordered eating (food/weight preoccupation, restriction, bingeing, purging, compulsive exercise) -> qualified eating-disorder professional
Diagnosed medical condition (diabetes, chronic kidney disease, heart failure, GI disease) -> registered dietitian or physician
Pregnancy or breastfeeding -> prenatal provider or registered dietitian
Unintentional weight loss, difficulty swallowing, or persistent GI symptoms -> medical evaluation
