Vegan Workplace Intervention

A billion people in the world are now overweight. That’s great news for the $13 billion weight loss supplement industry. As I detailed in my 2-min. video Diet Pills Do a Fat Lot of Good, a recent review of common slimming supplements versus placebo concluded that none of them worked any better than the sugar pills. Unfortunately it’s not just limited to weight loss supplements despite what one might be told in a natural food store. See my videos Dietary Supplement Snake Oil and Some Dietary Supplements May Be More Than a Waste Of Money, and then check out my series Health Food Store Supplement AdviceBad Advice From Health Food Store EmployeesDangerous Advice From Health Food Store Employees, and Pharmacists Versus Health Food Store Employees: Who Gives Better Advice?.

Recently a similar conclusion about diet pills was reached by the Weight Management Center at Johns Hopkins concluding, “it is fitting to highlight that perhaps the most general and safest ‘alternative’ approach to weight control is to substitute low-energy density foods for high-energy density and processed foods, thereby reducing total energy intake.” In other words, more whole plant foods and fewer animals and junk. The Hopkins paper continues: “By taking advantage of the low-energy density and health-promoting effects of plant-based foods, one may be able to achieve weight loss, or at least assist weight maintenance without cutting down on the volume of food consumed or compromising its nutrient value.”

The Physician’s Committee for Responsible Medicine decided to put this idea to work in a workplace dietary intervention study at GEICO corporate headquarters. Check out the video above for the results!

Irritating though I'm a fast reader, I couldn't read all this before the pages turned.

I tried at work, honest. My co-workers claim- I can't be a vegetarian, I like eating meat too much!"- ugh. Well, I at least got them to promise they wouldn't eat veal or foie gras...

There are many reasons why the number of vegans has doubled in the US in less than 3 years. Here are two uplifting videos to help everyone understand why so many people are making this life affirming choice: and

Thanks, Dr. Greger; it's so rare to find a vegan advocate that puts good science and facts in front of ideology, and it is much appreciated! Keep up the great work.
