Evidence-Based Nutrition Advice for Strength Athletes
Getting you stronger faster
To answer this question, we're going to look at a study published in 2011.
The aim of this study was to compare changes in :
All athletes included 4 resistance-training sessions/wk in their usual training regimen
The average amount of weight lost was 4.2kg for both groups. The fast weight loss group did it in 5.3 weeks, the slower group took 8.5 weeks.
Let's looks at some specific results now.
Changes in lean body mass:
Change in fat mass:
Changes in performance:
While both groups lost the same amount of body weight, their body composition changes were significantly different. This study suggests that slower rates of body weight reduction are better for preserving/gaining muscle mass as well as losing more body fat.
In terms of performance, we saw an increase in performance for both groups for most of the tests, as we should. These are elite athletes that are continuing to train, so improvements are expected. However, the percent increase in performance across all measures was significantly higher in the slower weight loss group.
This suggests that quick weight loss does not allow for as much athletic improvement as does slower weight loss. If your goal is to continue to improve while in a caloric deficit, you are much better off losing weight at a slower rate.
I will argue that I still think 0.7% of body weight loss per week is still a bit aggressive for most athletes, particularly strength athletes. In my experience, I start seeing a decline in performance for most people above 0.6% loss per week, and for some strength athletes, even that is too aggressive and we have to go with a more conservative 0.4% of body weight lost per week.
