One of the things I like about living a Primal lifestyle is that I don’t bother to count calories like I have with other diets in the past. This may be one of the things I like the most about it.
When people tell me they are “watching their calories”, but are still eating processed foods, but just fewer calories of them, I ask them how does 100 calories of spinach, eggs, chicken, etc. compare from a macro-nutrient perspective? If calories were the end all solution, do you think a 2,000 daily calorie diet eating pizza, pasta, and the like compared to one of whole foods low in carbs, high quality proteins, and good fats would result in the same outcome for your body, even if you did the same amount of exercise? I think you know the answer to this one!
The article below does a nice job of explaining more about calories and how they are very different from one another. The more you can learn about nutritionally dense foods that actually satiate you, versus high carb and sugar foods that only leave you more hungry in a matter of hours, the better of you will be in the long run!
