The energy balance model (calories in versus calories out) remains the fundamental and inescapable principle of weight management. Attempts to refute it rely on a major confusion between the raw physical energy of indigestible elements and the energy actually assimilable by the human body.

Scientific consensus firmly supports Dr. Idz's assertion that the energy balance model remains the pillar of weight management. A review by the International Society of Sports Nutrition (ISSN, Aragon et al., 2017) confirms that an energy deficit is the essential factor for body mass loss, regardless of macronutrient distribution. Furthermore, rigorous clinical research conducted by Kevin Hall at the National Institutes of Health (NIH) shows that the human organism strictly obeys thermodynamic principles. However, these same studies specify that our body is a dynamic system: metabolism actively adapts by adjusting its energy expenditure and satiety according to the types of food consumed. Dr. Idz's explanation is therefore scientifically sound, because energy balance only applies to the nutrients our digestive system is capable of breaking down and converting into usable energy. Attempting to discredit this principle with non-metabolizable matter is simply a biological confusion.
