❌ Not quite.
You picked no change. It did move. Across two trials, people who did the plan for 3 to 4 monthly cycles lowered their estimated biological age by about 2.5 years on average. The answer is B) About 2.5 years.
What worked: In two clinical trials of adults 18 to 70, people ate a low-calorie, mostly plant-based meal plan for 5 days a month, then ate normally, for 3 to 4 months. Compared with people on normal or Mediterranean-style diets, they had less insulin resistance, lower long-term blood sugar (HbA1c), less belly and liver fat, and an estimated biological age about 2.5 years younger.
The honest caveats: "biological age" here is an estimate from blood and health markers, not a measure of how long anyone will live. The diet was created by Valter Longo, who led the study and founded the company that sells it.
The company: L-Nutra, which sells the meal kit as ProLon. It is private, so there are no public shares.
Use it wisely:
Talk to your doctor first, especially if you take diabetes or blood pressure medicine, are underweight, pregnant or breastfeeding, or have a history of eating disorders.
If you try it, treat it as a monthly reset alongside the basics above, not a replacement for them.
