I am trying to find foods that are nutrient-dense, low in calories, and high in fat.
Fat is the most calorie dense macronutrient. So most high fat foods are going to be high in calories.
That being said, one food that strikes a good balance between fat content and caloric density is avocados. They are pretty high in fat, but also high in water, so they have a lower caloric density compared to other high fat foods like nuts, seeds, oil, etc.
100% grass-fed fatty beef (like ribeye). Super nutrient dense: B vitamins, vitamin A, zinc, iron.
100% grass-fed RAW milk. Vitamin K2, calcium, magnesium, incredibly beneficial bacteria.
Some of the healthiest, nourishing foods you can eat. Have saved my life.
1 gram of carbs had 4 calories,1 gram of protein 4 calories and 1 gram of fat 9 calories. This means that food with high fat content obviously has more calories. There is no such thing as low in calories high in fats
