Came across a great article regarding calories on the keto diet written by Nate Martins onhvmn.com.
It's a great read! Excerpt from the article below:
Are All Calories Created Equal?The question sparking hot debates in scientific circles!
The first law of thermodynamics (or the law of conservation of energy) states that energy cannot be created or destroyed. When applied to weight control, this law translates to the basic formula:
weight gain = energy (calories) in - energy (calories) out
This traditional viewpoint argues that the food eaten is unimportant–a calorie is a calorie. To lose weight, create a calorie deficit by either eating less or burning more. To gain weight, increase calorie intake.
The opposing viewpoint maintains that calories still count, but the type of food consumed has a trickle-down effect on the amount of energy expended, and what foods the body craves. It takes way more energy to process and store protein than it does carbohydrate or fat–this is called the thermic effect of food. Essentially, one burns more energy dieting protein because it requires more energy for the body to process. In one study, twice as much energy was expended after meals on a high-protein diet versus a high carbohydrate, low-fat diet.1
