Several years ago, I was able to stay lean by spending three hours at the gym every day. After my wife and I had children, I no longer had such a flexible schedule. It has since been difficult maintaining a healthy weight. I tried regular diets, ketones, and I even tried installing a treadmill in my home office. None of these kept the weight off reliably. I spent a lot of time researching thermogenesis since I am highly skeptical when it comes to these kinds of claims. I am a paid researcher at a world-renowned college in my field where I analyze quantitative data. After six weeks of wearing the CFB and CGB for one hour each session, I lost 2″ in the chest, 3″ in the stomach, and 2″ in my hips. This was without any drastic changes anywhere else in my lifestyle (diet, exercise, etc.). These products work as long as you are willing to incorporate them into your daily routine.
