Caffeine and other stimulants do have a down side though. Since stimulants act upon the central nervous system if used too often or for too long of a time period they can begin to cause overtraining effects. These effects would be much the same as if you were working out too long and too often. This can lead to decreased energy, muscle loss, and ultimately, a lowered metabolism since your body will be trying to preserve energy.
Do you really need to lose weight? We weren't all born to be thin or conform to society's definition of the ideal body. Your body size and shape depend on multiple factors, including your genes, eating patterns, Resting Energy Expenditure (see definition below) and exercise. You may want to accept and Love Your Body while trying to improve your health.
But back it up just a tad.....I started following FWTFL after a post I read on Seersucker + Saddles. I followed for a while, like months and months. It's easy to make excuses not to do something when you're afraid to step out of your comfort zone. Well, April rolled around and I turned 38. I realized ANOTHER year had passed by and I still wasn't in the shape I wanted to be in, so it was time to think about my priorities. You see, my plan was to be "fit for 40" but at the rate I was going 40 would be here and everything would be the same. I knew we had a couple vacations planned for the early summer so as soon as those were out of the way, I pulled the trigger for the July 10th bootcamp. Since the beginning I was super psyched to learn and take in as much as I could. It didn't take long to start noticing changes in my mood and my energy, and even in the physical changes my body started having! The best part was the confidence that came with all that and the determination to keep at it. Its almost (no, very) addicting to get in good health with results to show for it! Once you get a taste of it you want to have more-more of those body changes and certainly more of that "I can actually really do this" feeling! I never thought I'd have the willpower to do all that Ive done these past 6 weeks.
At its core, burning fat comes down to the process of lipolysis—the breaking down of fat lipids, explains Seedman. This happens in the mitochondria of the muscles, or the powerhouses of the cells, responsible for generating the energy our cells need to do their jobs. Exercise has been shown to improve mitochondria function, which then promotes fat breakdown, Seedman adds. Plus, working out helps regulate pretty much all the hormones that optimize fat loss.
