The only problem is this: a random croissant once a week as a treat is negligible to your overall calorie intake, but a daily croissant means you eat croissant for breakfast every day. Huge difference. In the book "French Women Don't Get Fat", one of the things that the author points out is that our invisible daily habits are the biggest factor in our calorie intake. If your commute walks you past a donut stand that you cannot resist, change your commute.
Of course if you have a well-worked-out diet and matching exercise plan that accommodates a daily croissant, this is great (with the air fryer).
