Nutrition counseling moves beyond diet tribalism

The brief

Joan Salge Blake argues that nutrition counseling should rest on evidence rather than personal opinion, then tests that principle against keto, low-fat, Mediterranean, paleo, and carnivore diets.

The central tension is short-term weight loss versus long-term health: restrictive plans may reduce food variety, but can also undermine fiber, vitamin C, calcium, vitamin D, and other nutrients.

A plant-forward pattern can still include meat, dairy, and eggs, while fiber, balanced protein distribution, and gradual dietary changes often matter more than fortified products or trend-driven rules.

The discussion treats glucose monitors, food order, fasting, and diet beverages cautiously: potentially useful tools, but poor substitutes for clinical context or evidence-based guidance.

Blake’s through line is practical rather than ideological: personalize nutrition, supervise restrictive diets, and collaborate with registered dietitian nutritionists when needs become complex.
