Experts rated the Flexitarian diet as one of the easiest to follow, largely because it promotes adding food groups rather than eliminating them. The plan earned 3.3 stars, above the average mark in this category. The Flexitarian diet emphasizes doing what you can—its name is based on the word flexible, after all—which makes it easier to stick to over the long haul.

Because it conforms to most of the federal government’s 2010 Dietary Guidelines, the Flexitarian diet earned an impressive 4 out of 5 stars. It’s a “nutritionally sound diet,” one panelist said, adding that its flexibility lowers the risk of nutrient deficiencies that often plague vegan diets.

The plan was considered very effective in the heart-health category. Experts handed out mostly 4s, with a few 5s, too. Research suggests that plant-based diets help keep blood pressure and cholesterol levels in check, and heart disease at bay.
