Exploring the controversy around spot reduction in fat loss, from whole body vibration and garments to recent evidence challenging the concept. Studies show mixed results on spot-reduction effectiveness, questioning the practicality of targeting specific areas. The podcast tackles misconceptions and unconventional methods, providing practical takeaways for listeners.
Spot reduction efficacy questioned for trained lifters combining resistance and aerobic training.
Nuanced perspective on spot reduction suggests specific muscle targeting effects over strict fat loss in trained individuals.
Targeted abdominal exercises may not lead to significant fat loss compared to general aerobic activities in college women.
Deep dives
History lesson: From the 1960s to 2010s
The study delves into historical research on spot reduction from the 1960s to more recent times. It highlights early studies by Moore and Olsen in the 60s, followed by a discussion on a 2017 study by Deepa Lumbo et al., focusing on combining resistance and aerobic training for regional fat loss. The study showed reductions in upper and lower limb fat mass alongside muscle mass increases, questioning the efficacy of spot reduction for trained lifters.
Deepa Lumbo and Brobachan's Study: Evidence of Spot Recomp?
The paper discusses the study by Deepa Lumbo et al., which garnered attention for its findings on spot reduction. The study involved untrained women engaging in upper body or lower body resistance and aerobic training. Results showed significant reductions in fat mass in the trained regions alongside increases in lean mass. This evidence, while pointing towards spot reduction, may imply a more nuanced perspective related to specific muscle targeting and potential recomp effects rather than strict spot reduction.
Local Fat Reduction and Muscle Hypertrophy Study
A study examined the potential for spot reduction alongside muscle hypertrophy in untrained males through abdominal aerobic endurance exercises. Results showed a significant reduction in fat mass in the abdominal region compared to a control group, despite both groups losing weight. However, the starting body fat percentage varied between the groups, suggesting the role of initial body composition in the results.
Sit-Up Exercise Training Study
Another study focusing on spot reduction involved individuals performing sit-up exercises daily for 27 days. While a significant decrease in adipose cell size was observed, there were no preferential fat reductions in the abdominal region compared to the control group. This study highlights that spot reduction through targeted exercises may not yield significant fat loss in specific areas.
Abdominal Exercise Program in College Women Study
A study involving college women examined the effects of abdominal exercises versus general aerobic activities on fat distribution. Results showed no significant differences in body composition changes between the two groups, indicating that spot reduction through focused abdominal exercises may not lead to significant fat loss in the targeted areas. Both groups maintained an isocaloric diet throughout the study.
In this episode, Greg, Pak, and Milo tackle the research around body fat spot reduction. First, they tackle the research on various ointments, creams, garments, and whole body vibration. Following this, they discuss the evidence for spot reduction as an adaptation to different exercise types such as endurance and resistance training.
