"But it was an ORGANIC cookie..."
I have actually heard this, and I wish it meant lower calories but too often it actually means higher calories. It is human nature to justify eating more of something if it is "healthy", but if our goal is losing weight then what matters most is a calorie deficit.
Healthy food choices can help us hit that calorie deficit by better controlling hunger and helping us feel more vital in general, but we have to be cautious justifying extras with the "eating clean" mindset.
Watch out for nuts and granola! Healthy? Yes. But packing some major calories. Also, check for health washing marketing terms like organic, veggie, natural, non-GMO, and gluten free.
