Hahah This is the most stereotypical Karen response that you would expect from someome who hasnt paid any attention to any of the current research post 2009. Its like the ttypical screed of "gyms, gyms, exercize, food composition hasnt changed!' Its changed dude, go watch Dr Lustig as a start from UCSF pediatrics on youtube. The fact that they have tens of millions of views and you"re still sitting here telling me about "calories in calories out' model can only mean you're not very attune to what's going around you. Yes composition of diet has changed, added sugars have increased dramatically, processed seed oils have largely replaced natural animal fats, and irs not a calories issue.
