There Really Is No ‘One Size Fits All’ Diet Plan

Have you ever followed your doctor’s weight loss nutrition plan to a T, only to stubbornly remain at the exact same weight — or worse, gain weight?

There’s a reason for that, according to an ambitious research project by scientists in Israel. Researchers Eran Elinav and Eran Segal of the Weizmann Institute of Science have just published the results of a large, comprehensive study in the journal Cell that found people can metabolize the exact same foods in very different ways.

What this means is that a healthy diet for one person may not be healthy for another person. Yet doctors all over the world tend to prescribe the same kinds of foods to people struggling with weight or health issues. Rather than recommend a cookie-cutter solution to weight problems, the researchers say, doctors could be more effective by recommending a personalized nutrition plan to a patient, based on the way that patient metabolizes certain foods.

“After seeing this data, I think about the possibility that maybe we’re really conceptually wrong in our thinking about the obesity and diabetes epidemic,” Segal said in a statement. “The intuition of people is that we know how to treat these conditions, and it’s just that people are not listening and are eating out of control — but maybe people are actually compliant but in many cases we were giving them wrong advice.”

Some fellow doctors, however, are a bit more skeptical about the pair’s conclusions.

The Study

To measure how food was digested, Elinav and Segal recruited 800 people and studied them intently over the course of one week. Participants were asked to log every bite, sip, exercise session, bowel movement and sleep session on a phone app. Their blood sugar levels were —> Read More
