The Toronto Star published a good article on the merits of moderation and the myth of the “diet”. It reads: There’s no magic formula for weight loss.
Still, there is one “diet” that works. It’s really more of a guideline, but it’s the closest to my personal philosophy about food:
The diet with the most robust evidence is the Mediterranean diet. Instead of food rules or absolutes, this is more about moderation: less meat, more veggies, and fruit for dessert. In this way of life, people shop for single-ingredient food at the market or the outer aisles of a grocery store, not the processed foods for sale in the inner aisles.
In combination with regular workouts (minimum 2 session/week), following these longterm habits will pay off.
