Despite what people say, microwaving food doesn’t cause it to lose anymore nutritional …more

what it claims

To optimize your diet and weight without unnecessary stress, free yourself from popular beliefs: the microwave does not destroy more nutrients than other cooking methods, bread is not inherently fattening, intermittent fasting is not superior to a simple caloric deficit, and organic foods are not more nutritious.

The creator challenges several common misconceptions about nutrition, and research largely supports his simplifying perspective. Regarding the microwave, a review study published in the Journal of Food Science confirms that this rapid cooking method often preserves water-soluble vitamins better than traditional boiling. For intermittent fasting, a rigorous randomized controlled trial (RCT) published in the New England Journal of Medicine shows that it offers no superior advantage for weight loss compared to conventional caloric restriction over the long term. As for organic food, a large-scale meta-analysis from Stanford University concluded there is no major nutritional difference in the composition of these foods compared to conventional ones. Finally, nutritional science confirms that bread is not inherently fattening, as weight management depends on the balance of total energy intake. Only the claim of '0% nutrient loss' in the microwave is a slight hyperbole, as any exposure to heat alters certain sensitive compounds to some degree.

What the graded evidence says

Evidence
B
Effect
antioxidant activity and vitamin retention by cooking method — microwaving and steaming produced among the lowest losses of antioxidant capacity across 20 vegetables, while boiling and pressure-cooking produced the greatest losses; water-soluble vitamins are lost mainly to cooking water
Measured on
general population (food-composition/cooking studies)

What’s uncertain

The exact best method varies by vegetable and nutrient, but the general pattern (less water and less time = fewer losses) is consistent. No cooking method keeps 100% of nutrients.
