what it claims

For women looking to lean out, an excessive caloric deficit is counterproductive: it leads to loss of muscle mass, low energy availability, and the risk of hormonal imbalances.

This advice is based on sound principles of sports physiology. Scientific literature, notably meta-analyses on sports nutrition, confirms that 'Low Energy Availability' (LEA) can indeed disrupt the hypothalamic-pituitary-gonadal axis in women, causing hormonal disorders (meta-analysis, Journal of the International Society of Sports Nutrition). Regarding muscle loss, studies show that sufficient protein intake combined with a moderate caloric deficit is essential to preserve lean mass during a cutting phase (RCT, Journal of the International Society of Sports Nutrition). The assertion that muscle is crucial for a 'toned' appearance is also validated, as muscle tissue is metabolically more active than fat. Abbey Sharp uses a balanced approach here by noting that chronic under-eating harms long-term results. No point appears exaggerated; she even nuances her statement by specifying that an isolated video does not necessarily reflect a person's actual diet.

What the graded evidence says

Effect: cardiometabolic risk factors (human CR); lifespan (animal drug studies) — ~12% achieved calorie restriction over 2 years significantly lowered LDL, total-cholesterol/HDL ratio, and blood pressure (RCT, n=218); metformin and acarbose extend lifespan in mice, with no completed human longevity trial
Measured on: healthy non-obese adults (CALERIE); mice (metformin, acarbose lifespan)

Human calorie-restriction evidence is about risk-factor markers over a couple of years, not proven lifespan extension. The longevity-drug hype rests on animal data; there's no completed human trial, and taking prescription drugs off-label for aging is a medical decision, not something Noli advises.
