I'm the same weight I was as a teenager, and I've never stopped eating butter and adding cream to my coffee.

Not ALL fats are bad: Consuming good fats can actually prevent stroke

"In the study, researchers evaluated the relationship between various biomarkers of fatty acids found in dairy fat with heart disease and mortality. They looked at almost 3,000 adults aged 65 and older and measured their plasma levels at various points over the course of 22 years. They determined that while none of the fatty acid tapes tested were linked to total mortality, one type was actually linked to a lower incidence of cardiovascular disease death. Moreover, those with higher fatty acid levels, which indicates higher whole-fat dairy consumption, had a remarkable 42 percent reduced risk of dying from stroke."
