Researchers looked at how whey protein affects people who have undergone bariatric surgery for obesity. The study included 267 participants to see how protein supplements changed body weight, body mass index (BMI), and fat levels.
The results showed that taking whey protein may help preserve fat-free mass while decreasing total fat mass. It also appeared to slow the drop in body weight and BMI after surgery. However, the study found that whey protein had a limited impact on lipid profiles, which are markers for cholesterol and fats in the blood.
It is important to note that the quality of the evidence was rated as moderate to very enough low for all measured factors. Because the current data is limited, these findings should be viewed as preliminary. Talk with your doctor to see if whey protein is a safe and helpful addition to your specific post-surgery nutrition plan.
Common questions
Does whey protein help with body composition after weight loss surgery?
The study suggests that whey protein supplementation may help preserve fat-free mass and decrease fat mass in patients after bariatric surgery. It also showed a link to slowing the reduction of body weight and BMI. However, researchers noted that the evidence quality for these results is currently moderate to very low.
Does whey protein improve cholesterol or lipid levels?
The study found that whey protein supplementation had a limited impact on lipid profiles. This means it did not show a significant change in the markers used to measure fats in the blood for the patients studied.
Is whey protein safe for people who have had bariatric surgery?
The study did not report any specific adverse events or safety concerns. Because the evidence is currently limited and of moderate to very low quality, you should speak with your healthcare provider to determine if it is right for you.
