Milkonly

Milkonly is a term used to describe a dietary practice in which milk serves as the sole source of nutrition for a defined period. The practice generally centers on dairy milk, most commonly cow’s milk, though some descriptions may reference other animal milks. In some variants, only milk and water are permitted; in stricter forms, other foods are excluded entirely.

Purpose and use vary. People may undertake a milk-only plan for short-term fasting, perceived digestive rest, or weight-management goals. It appears in diet books and online communities, but it is not endorsed as a safe or healthy long-term diet by major nutrition authorities.

Nutritional profile and limitations. Milk provides protein, lactose carbohydrates, fats, calcium, potassium, and several vitamins. However, a milk-only diet offers little or no dietary fiber, iron, vitamin C, and several other micronutrients. Fortified milk may supply vitamin D, but even with fortification it is unlikely to meet all nutritional needs if followed beyond a brief period. The diet also excludes variety that supports gut health and long-term nutrient balance.

Health considerations and risks. Potential issues include nutrient deficiencies with prolonged use, lactose intolerance symptoms, dairy allergies, and imbalanced energy intake. It may also contribute to unhealthy eating patterns if adopted compulsively or without medical supervision.

History and reception. Milk diets have appeared in historical and alternative-health literature but lack robust scientific support for sustained use. They are generally viewed as inappropriate as a regular eating pattern.
