What is probably the worst reasons to try something is because someone says, “It worked for me!” This is true with diets, exercise, supplements, or following some “guru”.
One story from my college days (yes, many, MANY years ago) is a perfect example of this. I was working in the university weight room and saw a huge bodybuilder doing concentration curls (one arm curls in which you’re seated with your elbow resting on the inside of your thigh). He had giant biceps. While curling with one arm, he held a metal pipe in the other and was hitting his biceps with it. I had to go ask what that was all about. He said that by hitting his muscle with the pipe, he was breaking down the muscle faster to build it up bigger…and who was going to argue with him, it must work, right. Whoa… big time wrong! That’s not how muscle breakdown and building works. “Well, (naysayers will say) if it didn’t work, why was he so big? Huuhh?” Well, let’s think of all the other things he could be doing. His diet was probably supplying the right amount nutrients. He was working out hard, even without the pipe. He probably had some genetic advantage, aaand… at that time, it was likely that he was taking anabolic steroids. Still, he said it was the pipe and people would surely believe him.
Any exercise program will give results to someone who hasn’t been exercising. It doesn’t mean it is the safest, most effective exercise program. It is just that now you’re following a program and doing some kind of exercise.
Almost all diets will give weight loss results short-term. Whether they are cutting out food groups (paleo, ketogenic, vegan) or managing when you eat (intermittent fasting) or has you track your points (weight watchers), they all will manipulate you into eating fewer calories. Fewer calories = weight loss (at least short term). (Marie Spano, MS, RD, CSCS, CSSD, has a great post here.)
All that said, I do hope that all of our clients are saying, “Try Jiva Fitness! It worked for me!” What’s the difference? Do your research. If it’s an exercise program or a diet/eating plan, what is it based on? Is there scientific evidence to back it up. Who are the people that created it? Are they qualified professionals? Don’t go blindly into things that are in the popular news. After all, even the Shake Weight was popular for a short time.
