Eating a few chocolates during the holidays will have no measurable impact on your ideal weight, as it would require accumulating a colossal surplus of 7,000 calories above your usual needs to store the equivalent of 1 kg (2 lbs) of fat.

The creator relies on the well-known "3,500 calorie rule per pound of fat," initially theorized by Dr. Max Wishnofsky (tissue analysis study, 1958). In energetic terms, this equivalence is a robust approximation for understanding short-term storage potential. Nevertheless, the work of Dr. Kevin Hall at the NIH (based on controlled clinical trials and metabolic modeling, 2011) reminds us that the human body is not a simple linear mathematical operation and that it adapts its energy expenditure in the face of excess. In the event of a temporary caloric surplus, part of the excess is naturally dissipated through increased thermogenesis or spontaneous activity. The creator's main conclusion therefore holds up perfectly: small festive indulgences do not translate into permanent fat storage. Furthermore, sudden variations on the scale after a hearty meal are scientifically explained by fluctuations in water and glycogen stores, not by adipose tissue created instantly.
