Eat as much as you want, just not WHAT you want

A standard prescription for weight loss is to reduce the amount of calories you consume. In a new study, published in JAMA*, people who ate lots of vegetables and whole foods rather than processed ones lost weight without worrying about calories or portion size.

It found that people who cut back on added sugar, refined grains and highly processed foods while concentrating on eating plenty of vegetables and whole foods — without worrying about counting calories or limiting portion sizes — lost significant amounts of weight over the course of a year.

“The strategy worked for people whether they followed diets that were mostly low in fat or mostly low in carbohydrates. . . .. their success did not appear to be influenced by their genetics or their insulin-response to carbohydrates, a finding that casts doubt on the increasingly popular idea that different diets should be recommended to people based on their DNA makeup or on their tolerance for carbs or fat.”

The study compared  how overweight and obese people would fare on low-carbohydrate and low-fat diets . . .  and tested the hypothesis — suggested by previous studies — that some people are predisposed to do better on one diet over the other depending on their genetics and their ability to metabolize carbs and fat. (A growing number of services have capitalized on this idea by offering people personalized nutrition advice tailored to their genotypes.)

The participants were encouraged to meet the federal guidelines for physical activity but did not generally increase their exercise levels,

The new study stands apart from many previous weight-loss trials because it did not set extremely restrictive carbohydrate, fat or caloric limits on people and emphasized that they focus on eating whole or “real” foods — as much as they needed to avoid feeling hungry.

They did not have to restrict or even think about calories.

“Dr. Walter Willett, chairman of the nutrition department at the Harvard T. H. Chan School of Public Health, said the study did not support a “precision medicine” approach to nutrition, but that future studies would be likely to look at many other genetic factors that could be significant. He said the most important message of the study was that a “high quality diet” produced substantial weight loss and that the percentage of calories from fat or carbs did not matter, which is consistent with other studies, including many that show that eating healthy fats and carbs can help prevent heart disease, diabetes and other diseases.”

It was a large and expensive trial, carried out on more than 600 people with $8 million in funding from the National Institutes of Health, the Nutrition Science Initiative and other groups.

  1. This is excellent info and a diet I should follow every day. One of my biggest problems is when i’m out and getting really hungry and still have 2 – 3 hours of planned errands. Or when I’m just plain tired (often) and don’t want to cook – easy for me to say because I hate to cook under the best of circumstances, and hubby’s best cooking skills run to blowing up the wrong cookware on the stove – no matter what I tell him.

    So, yes, I could carry around carrots and apples but I’m unlikely to do so and they won’t fill me anyway. There are solutions to my problems – I have to make better choices. And I DO know that.

    Eating less crap and eating better food is the way to reduce weight and inches. Exercising is the way to get the whole body in better physical shape. I should do this part too.

    Again, thanks for the kick in the keister.


    • Sharon,
      I know, I hate it when I am out and want to do more things but I am also hungry. I don’t want to bother to go eat, but I know I am not doing my best thinking, so I don’t want to make major decisions (I would t want to buy a car while hungry). Nuts and seeds are easy to carry around and maybe better than carrots–especially with a few pieces of semi sweet chocolate :). But I rarely think to have them with me.
