Abstract:
Introduction: The effects of prolonged consumption of whey protein on health
are controversial. This study aimed to determine whether whey protein positively
alters health parameters of overweight and obese adults. Methods: Randomised
controlled trial was conducted. Fifty-eight participants, aged 30-50 years, were
randomly allocated into four groups and supplemented with 50 g protein for eight
weeks (group 1: plant-based protein (PBP), group 2: whey protein isolate (WPI) with
cocoa powder, group 3: PBP with whey protein concentrate (WPC), and group 4: WPI
with milk powder). Body composition and biochemical parameters (kidney and liver
functions, inflammation, oxidative stress, and antioxidant capacity) were evaluated
at pre-intervention and 8 weeks after intervention. Results: At Week 8, group 3 had
lower diastolic blood pressure, waist circumference, visceral fat, and risk of insulin
resistance (p<0.05 for all). Group 2 had decreased levels of total cholesterol and
low-density lipoprotein cholesterol (p<0.05 for all). A drop in triglyceride was seen in
group 4 (p=0.026). Whey protein decreased alanine aminotransferase level (p=0.028),
while PBP increased aspartate aminotransferase level (p=0.034). PBP or WPI with
milk powder increased blood urea nitrogen level (p>0.05 for all). Interleukin-6 and
lactoferrin levels fell in all groups (p<0.05), while hs-CRP increased in the PBP
group (p=0.043). Group 2 experienced increased antioxidant capacity. However,
levels of oxidative stress markers were significantly decreased in the PBP group and
WPI with milk powder group. Conclusion: Whey protein revealed positive effects
on anthropometric parameters and biochemical markers of overweight and obese
adults. Therefore, proper supplementation of whey protein can potentially promote
health.
