Layne Norton's position aligns with a significant portion of current research on non-caloric sweeteners. Numerous meta-analyses and randomized controlled trials (RCTs), such as those published in 'Obesity Reviews', indicate that these substances do not systematically increase immediate energy intake or sensations of hunger in humans. The idea that they 'trick the brain' into inducing overconsumption remains a mechanistic hypothesis poorly supported by actual behavioral data. However, the research is nuanced: while the impact on short-term hunger is globally neutral, some observational studies suggest complex long-term correlations with weight, without establishing a direct causal link via hunger. It is therefore accurate to say that the claim that sweeteners mechanically create uncontrollable hunger is scientifically fragile. The advice is well-supported by current data on appetite regulation, although individual metabolic responses may vary slightly.

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.
