Plant-based eating has surged in popularity, but not everyone wants to give up animal products completely. That’s where the Flexitarian Diet comes in.
The flexitarian (flexible + vegetarian) diet emphasizes plant-forward meals while still allowing moderate amounts of meat, poultry, or fish. This makes it easier to sustain long-term compared to strict vegetarian or vegan diets.
In this guide, Dr. Sherif and Sarah Johnson explains the flexitarian diet, its health benefits, and how to adopt it for safe, sustainable weight loss.
What Is the Flexitarian Diet?
Plant-Forward: Fruits, vegetables, legumes, and whole grains form the base of meals.
Flexibility: Meat and dairy are allowed, but in smaller amounts.
No “Rules,” Just Balance: Focus is on gradual shifts rather than strict restrictions.
👨⚕️ Doctor’s Note: “The flexitarian approach is often more realistic for patients. It combines the benefits of plant-based eating with the flexibility to enjoy animal protein in moderation.”
