In the metrics that matter, a simple “high-quality” diet is best.
There are lots of different health-based diets out there. They can be distinguished from one another in various ways. Perhaps the two most important variables to consider when choosing a healthy diet to follow are research-proven health benefits and restrictiveness.
The very point of a health-based diet is its health benefits, of course. Proponents of each specific diet will, naturally, argue that theirs offers the greatest number and degree of health benefits. But you can’t take their word for it. You have to look at what real science says about it.
Some diets are more restrictive than others. That is, some have longer lists of prohibited foods than others. As a general rule, the more restrictive a diet is, the more difficult it is to sustain. Again, proponents of each specific diet will present themselves as living proof that it’s sustainable, but what’s sustainable for one person might not be for another.
Let’s look at the proven health benefits and restrictiveness of various diets.
