Discussion: Will identical twins who eat the same calories but in different compositions (natural vs. processed) and perform the same activities show the exact weight change?

The answer is "not necessarily." The explanation stems from the fact that food composition is essential. Their tissue rehabilitation requirements are not necessarily the same, and their gut flora is not the same. Different absorption of nutrients resulting from diverse intestinal gut flora and other needs for tissue regeneration may lead to different routes of nutrients for non-caloric needs. These discoveries are reflected in a technology called the "fecal transplant," which contradicts the common thought that all calories are equal. Calories in the lab are not the same as calories within the human body.
