What is the logic behind putting butter in your coffee? If your goal is to lose weight, wouldn't not eating that butter still be better than eating it?
You're stuck in the mindset that fat makes you "fat". This is the whole point of ketosis, and a rethinking of wrong dietary guidelines that have persisted for decades. The butter in the coffee supplies fat for fuel / energy, suppresses appetite, and does not contribute to weight gain or more specifically an increase in adipose fat tissue. Simply cutting all calories is futile. Your body needs energy to sustain itself…
Edit: I get the point that it stops hunger, but my point still stands, and the parent posters still doesn't make a great deal of sense.
