According to a new meta-analysis – that means a review of mountains of research studies – published in the Journal of the Academy of Nutrition and Dietetics on Thursday, Jan. 22, 2015, adopting a vegetarian diet causes weight loss, even in the absence of exercise or calorie counting.

The review analyzed 15 studies, conducted with 755 participants in Europe and the United States.

Remember, this was without the layer of calorie counting or ramping up exercise.

“I eat foods with fiber”

Several years ago I interviewed a plant-based doctor who had devised a brilliant rule for deciding what was to put on his plate that would keep him well fed yet trim.

He told me his rule: “I eat foods with fiber”.

If it didn’t have fiber in it, it didn’t make its way to his plate.

Everything on a whole foods plant-based diet is inherently fiber rich.

Animal products – meat, eggs, dairy – are all completely fiber free.  Highly refined foods are right in there with coming up seriously devoid if not completely absent of fiber.  Also juices and vegetable oils.

Number one secret to ease of weight loss with a plant-based diet


Perhaps the strongest reason people lose weight more easily on a plant-based diet than other dietary approaches is because of the fiber content of a plant-based diet. Though most Americans consume a pathetic 10 – 15 grams of fiber a day, if that – The Physicians Committee recommends consuming close to 40 grams of fiber a day.

Consuming this  amount of fiber is easy to do when vegetables, fruits, whole grains, and legumes are at the center of your plate.

The chart below provides a handy tool for you to quickly assess where your personal fiber count measures up.
