From my point of view (currently mid 40s and undergoing my very first attempt at losing weight in my life), losing weight of course means consuming fewer calories than you burn. However, eating healthy foods is what makes that a less miserable experience. Eating foods that take a while to digest and sit in your stomach for a while making you feel full like whole grains, nuts, fresh fruit and vegetables, and enough protein to keep your muscle mass, will make it a lot more likely to lead to success than simply "eating less."
