what it claims

Do not be misled by the sensationalist claim that Coke Zero contains 1,000 calories: this is a confusion between the scientific (physics) calorie and the dietary calorie (kilocalorie). Nutritionally, Coke Zero provides a completely negligible amount of energy (about 1 kcal per can).

The creator's explanation regarding the distinction between the physical calorie and the dietary calorie (kilocalorie or kcal) is entirely accurate and based on thermodynamic definitions. From a regulatory standpoint, European Regulation (EC) No 1924/2006 (regulatory standard) validates the 'calorie-free' labeling for beverages providing less than 4 kcal per 100 ml, which is the case for Coke Zero. Regarding weight management, a meta-analysis of clinical trials (RCT) published by Laviada-Molina et al. (2020) shows that replacing sugary drinks with sweetened versions helps reduce overall energy intake. Furthermore, a systematic review of clinical trials (RCT) by Rogers et al. (2016) confirms that these alternatives do not increase caloric intake and support weight loss. The creator therefore provides a very sound scientific clarification to dispel an unfounded misunderstanding linked to dramatization on social media.

What the graded evidence says

Effect: body weight (RCTs, sweetener replacing sugar) vs long-term outcomes (WHO systematic review) — small average weight reduction (~1 kg) when swapping sugar for sweeteners in short-term RCTs; no sustained body-fat benefit long term, with observational associations to higher T2D and CVD risk
Measured on: adults and children; general population

The short-term weight edge is real but small; the long-term concerns (T2D, cardiovascular) are observational and can't prove cause. The aspartame 'possible carcinogen' label reflects limited evidence at very high exposure, not everyday-can risk. Reasonable people can disagree, hence WHO's recommendation is conditional.
