Walking with a Weighted Vest for 30 Days - What to Expect, ft. @TheScienceofSelfCare
Summary
TLDRThis video explores unconventional methods for getting leaner and more muscular, focusing on the use of weighted vests. It delves into a 2019 study that suggests bones play a role in fat loss and features Robin's personal experiment wearing a weighted vest for a month. The video contrasts Robin's experience of increased strength and hunger with the study's findings, which showed no significant change in fat-free mass but did indicate body fat loss. The discussion highlights the role of osteocytes in modulating metabolism and food intake, suggesting that weighted vests may help in body fat reduction. The video concludes with practical advice on how to incorporate weighted vests into a fitness routine, emphasizing the importance of starting with the right weight and considering the distribution of the vest for comfort and effectiveness.
Takeaways
- đïžââïž Wearing a weighted vest can increase exercise intensity, leading to greater sweating and heavier breathing within minutes.
- đŠ” After a few days of wearing a weighted vest, there's a noticeable change in leg strength and tone, making regular walking feel easier.
- đ Research indicates that wearing a weighted vest doesn't necessarily increase fat-free mass, but it can enhance strength through improved neural signaling.
- đœïž There's a significant increase in hunger after wearing a weighted vest, likely due to the additional effort required to move with the added weight.
- đ§ The body's response to a weighted vest is different from adding biological mass like muscle or fat, as it involves the skeleton and osteocytes, which sense strain on the bones.
- đ Animal studies show that loading mice with weights led to a decrease in body fat, suggesting a similar effect could occur in humans.
- 𧏠Osteocytes play a crucial role in modulating food consumption and metabolism in response to added weight, as seen in the mice with ablated osteocytes losing the weight loss advantage.
- đ¶ââïž Walking with a weighted vest for 20 to 60 minutes daily can lead to increased strength and a toned feeling, even without significant changes in body composition.
- đ The optimal weight for a weighted vest is around 11% of one's body weight, but it's important to start with a weight that is comfortable and gradually increase if desired.
- đ Wearing a weighted vest can help improve posture due to the increased awareness of the body's alignment under the added weight.
Q & A
What was the main topic discussed in the 2019 study mentioned in the script?
-The main topic of the 2019 study was the unconventional way that our bones help us lose body fat.
What was Robin's experience after wearing a weighted vest for a short period?
-Robin experienced increased sweating, heavier breathing, and a higher intensity workout within 5 to 10 minutes of wearing the vest. She also noticed her legs felt stronger and more toned after a few days.
How did wearing a weighted vest affect Robin's daily activities?
-Wearing the weighted vest made walking and lifting groceries easier for Robin, as she felt stronger and more accustomed to the added weight.
What was the outcome of the randomized control trial regarding fat-free mass and the use of weighted vests?
-The randomized control trial showed that the use of weighted vests did not lead to a change in fat-free mass, as indicated by the data where the bars were about the same as the baseline.
Why might Robin's experience of increased strength not be reflected in the study's fat-free mass results?
-Strength is not solely influenced by muscle mass but can also be improved by improved neural signaling. Additionally, the study may not have been powered to detect small differences.
How did wearing a weighted vest affect Robin's appetite?
-Robin noticed an increase in hunger, especially after long walks, which led her to eat more during the month she was experimenting with the weighted vest.
What was the observed change in body weight and body fat for the participants in the study who used a weighted vest?
-The participants in the study lost body fat when using the high load vest, but the study did not find an increase in hunger among them.
What role do osteocytes play in the body's response to wearing a weighted vest, according to the 2019 study?
-Osteocytes, the cells within bones, sense the strain on the bone when a weighted vest is worn and secrete factors that influence the body's metabolism and food intake.
What was the main sponsor mentioned in the script, and what was the humorous aspect of their sponsorship?
-The main sponsor mentioned was 'Elephant Vests,' a fictional company that humorously suggested using actual elephants as weighted vests.
What advice did Robin give regarding the use of weighted vests to avoid discomfort?
-Robin suggested considering using a weighted belt instead of a shoulder strap vest to avoid discomfort, especially in the shoulders and spine.
What was Robin's protocol for using the weighted vest, and what was the recommended starting point based on the studies?
-Robin's protocol was to walk with a 30 lb vest for 20 to 60 minutes daily. The recommended starting point based on the studies was to use a vest weight equivalent to 11% of one's body weight.
