Which summary best explains why fat blockers may help short-term weight loss but pose concerns for long-term nutritional status?

Fat blockers permanently rewire metabolism so that fat is converted into muscle over time; they present no nutritional concerns but can reduce body fat to dangerously low levels in the short term.

Fat blockers are inert supplements with no measurable effect on calories or vitamin absorption; any observed weight loss is due to placebo and therefore there are no long-term risks.

Fat blockers directly supply fat-soluble vitamins to users; therefore they protect against malnutrition while promoting appetite suppression, making long-term supplementation entirely safe.

Fat blockers reduce caloric absorption from fat, modestly aiding weight loss, but also limit absorption of essential fatty acids and fat-soluble vitamins, raising the risk of deficiencies and digestive side effects with prolonged use.
