Time matters when it comes to whey protein

Washington D.C. [U.S.A.], May 24 (ANI): Turns out, in order to manage weight, the time of consumption of protein supplements matters.
According to a study conducted by the Purdue University, people looking to manage their weight with strength-training and protein supplements should consume their supplements during a meal.
"It may matter when you take your supplements in relation to when you eat meals, so people who consume protein supplements in between meals as snacks may be less likely to be successful in managing their body weight," said Wayne Campbell, senior author on the study.
The study was led by Joshua Hudson and graduate research assistant Robert Bergia also contributed.
Protein supplements are available in ready-to-drink, powdered and solid forms, and often contain whey, casein or soy proteins. They can help with weight gain, weight loss or weight management based on how they are incorporated into an eating plan and taken with meals or as snacks.
"This is really the first time that the issue of timing when supplements are consumed in regard to meals has been looked at," Hudson said. "This review needs to be followed up by rigorous studies to better evaluate the timing of protein supplements in relationship to meals."
Their analysis of research studies found that while protein supplementation effectively increased lean mass for all groups, consuming protein supplements with meals helped maintain their body weight while decreasing their fat mass. In contrast, consuming protein supplements between meals promoted weight gain.
The timing likely makes a difference because a person may tend to adjust their calories at a meal time to include the protein supplement.
"Such dietary compensation is likely missing when protein supplements are consumed as snacks. Calories at meal times may not be adjusted to offset the supplement's calories, thus leading to a higher calorie intake for that day," said Campbell, whose expertise integrates human nutrition, exercise physiology and geriatrics. "If the goal is to manage weight, then snacking on protein supplements may be less effective. People who are trying to gain weight may consider consuming protein supplements between meals."
More than 2,000 nutrition articles were screened across journal databases to identify 34 studies with 59 intervention groups that were related to this topic.
The studies were selected based on specific factors including inclusion of healthy adults, evaluating consumption of protein supplements between meals or with meals, whether results showed a change in lean muscle mass, and a minimum of six weeks duration for each of the studies.
The findings from the study are published in the journal Nutrition Reviews. (ANI)
