THE TWO OF THEM. CHRIS YOU CUT OUT FATS?>>FOR A MONTH, I HAD NO CARBS OR SUGAR. I LIVED ON MEAT, CHEESE, EGGS. >>WHAT DID YOU DO?>>I CUT OUT FAT. MY FOOD LOOKED NORMAL. EATING WAS A JOYLESS EXPERIENCE.>>WHICH IS INTERESTING BECAUSE THE TWO OF YOU BOTH LOST WEIGHT. HOW MUCH DID YOU LOSE?>>I LOST MUCH MORE. I THOUGHT I WAS WINNING. AT THE END OF THE MONTH I LOST EIGHT POUNDS. I ATE AS MUCH AS I WANTED. I ATE STEAK MOST NIGHTS AND FELL GOOD. ENERGY LEVELS WERE LOW BUT CONSTANT THROUGH THE DAY. I DIDN’T HAVE SPIKES.>>AS COMPARED TO CHRIS?>>I LOST TWO POUNDS. AT THE END OF THE DIET BEFORE WE WENT BACK TO RESEARCHERS AND DISCUSSED THE RESULTS, HE WAS CONVINCED HE SHOULD STAY ON HIS DIET. HERE’S THE KEY THING. ALTHOUGH XAND LOST WEIGHT, BY EVERY OTHER MEASURE, HIS DIET HAS BEEN BAD FOR HIM. >>IN FACT YOU ENDED UP PREDIABETIC?

TRYING TO SEEK A SIMPLE SOLUTION IS DIFFICULT. >>YOU’RE BOTH DOCTORS?>>YES, BOTH PHYSICIANS.>>WE WERE JOKING BEFORE PHYSICIANS AREN’T ALWAYS THE BEST PATIENTS.>>OH YEAH. TERRIBLE PATIENTS. MOST DON’T KNOW THAT MUCH ABOUT NUTRITION.>>SPEAK FOR YOURSELF.>>WHAT DID MOVEMENT MATTER IN THIS? DID YOU EXERCISE REGULARLY OR NOTHING?>>WHAT WE WERE NORMALLY DOING. WE’RE BOTH IN REASONABLE SHAPE.>>YOU BOTH LOOK FIT. >>THE BIG TAKE HOME MESSAGES FOR US WERE PROBABLY THE REASON WE’RE ALL GETTING — NOT ALL OF US, YOU LOOK GREAT — OBESITY IS RISING GENERALLY NOT BECAUSE OF ONE MOLECULE FAT OR SUGAR. THE PROCESSED FOOD IS HARD TO STOP EATING. IT AFFECTS YOUR B
