Calories are not just calories. They're a useful rule of thumb but they're not a metric to live and die by. Always remember that calorimetry is basically burning mass(nut) and measuring energy(nut) by how much it increased the temperature of some water. Combustion is an extremely primitive hand wave over the VERY COMPLEX digestive system not to mention how we then go on to store that energy (glycogen vs fat) and then eventually burn that energy. Drinking x ml of olive oil vs eating y g of nuts for equal calories will have different outcomes even though they're primarily both fats. Fiber is key and will affect energy absorption intake. Even chewing efficiency will affect how well you absorb that energy. Let's not forget that digestion itself takes energy. Obviously if you eat an extra 2kcal of nuts a day you're going to see the effects of that, but calorie for calorie, I'd rather eat nuts than a big mac or ice cream (and expect to see less weight gain) Or being healthy - I'd rather have whole almonds supplementing my meals than cottage cheese (from a pure calories perspective)
