Christine Tangney, is an associate professor of clinical nutrition at Rush University Medical Center in Chicago. “People in their 70s and 80s should not be consuming more than 2,100 calories per day,” she says. “Anyone consuming that many calories is at risk for many diseases including poor cognition and obesity.”

This study most certainly does not offer this conclusion, nor does any other study currently in existence. More research needs to be done pertaining to macronutrient breakdowns.

I consistently find the opinions of nutritionists (even clinical ones) completely laughable when it comes to interpreting science and making recommendations.
