Early or partial results. Treat as a signal, not a conclusion.
This preclinical study in Wistar rats demonstrates that bovine milk whey supplementation in offspring of obese dams produces partial metabolic restoration, notably reducing body weight and cholesterol but failing to reverse glucose intolerance, elevated corticosterone, or anxiety-like behaviours. The incomplete effect profile and rodent-only design mean this remains exploratory evidence requiring replication in larger animal studies and eventual human trials before clinical interpretation is possible.
Controlled animal study (rodent model), factorial design. Male Wistar rat offspring from dams fed standard or hypercaloric diet; studied post-weaning.. Intervention: Bovine milk whey (MW) supplementation administered to offspring after weaning.. Compared with: Standard diet without milk whey supplementation.. Not stated.
Maternal hypercaloric diet increased offspring serum corticosterone, LDL cholesterol, fasting blood glucose, and glucose intolerance; milk whey did not affect these changes. Milk whey supplementation reduced body weight and blood cholesterol alterations in offspring from hypercaloric-fed dams. Anxiety-like signs in offspring from hypercaloric dams were not reversed by milk whey.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Single-centre animal study with mixed results: MW supplement partially restored some metabolic markers but failed to affect key endpoints including glucose intolerance, corticosterone, and anxiety-like behaviour.

What is missing. This record has no reported figures. That is a gap in the analysis, not a judgement about the study.
Maternal obesity has been associated with offspring fetal programming, increasing the risk of developing chronic diseases in adulthood, including type 2 diabetes, hypertension, and behavioral disorders such as anxiety and depression. Milk whey (MW) peptides, administered as a supplement, reduce food intake and body weight in overweight rodents. The aim of this work was to study the possible metabolic and behavioral restorative effects of a bovine MW supplement against the negative fetal programming of juvenile offspring. Dam Wistar rats were fed during gestation and lactation with a standard (SD) or a hypercaloric diet (HD); after weaning, the male offspring were fed SD or SD and MW. HD dams showed increases in blood cholesterol, body weight, and calorie intake, while administering MW in offspring from HD mothers reduced these alterations. Serum corticosterone, LDL cholesterol, fasting blood glucose, and glucose intolerance were significantly higher in offspring from HD dams; however, MW did not affect these changes. Offspring from HD dams showed signs of anxiety that were not reversed by MW, as well as a reduction in hippocampal BDNF that was partially restored with MW. Maternal HD consumption during pregnancy and lactation elicited negative developmental programming of adult offspring metabolism, which was partially restored by bovine MW supplementation.
