First, if you don’t recognize the women in the above photo, it’s Jillian Michaels from the popular reality show, “The Biggest Loser. ” Apparently, she’s being sued by someone who was dissatisfied with the lack of weight loss results from the dietary supplement endorsed by Jillian Michaels. If Scott Welch is correct, then wouldn’t a refund suffice?
Back on topic… A recent study published in the Journal of Physical Activity and health compared the effects of three different types of training (for 8 weeks) on body composition and blood lipid profiles in untrained men.
Three Study Groups:
- Strength training
- Endurance training
- Concurrent training (in the same overall regime)
What this study found was that the group that did strength training alone for 8 weeks improved their fat-free mass as well as their triglyceride and cholesterol levels. However, resistance training alone did not benefit HDL, LDL profiles or body fat percentage.
In contrast, the group that only did endurance training benefited from a decrease in fat mass, improved HDL, LDL, and triglyceride profiles, but did not improve their fat-free mass.
Finally, the concurrent group simultaneous improved their lipid profile (HDL, LDL, triglycerides) and body composition (decrease fat mass, increased fat-free mass).
Bottom line: it’s more effective to do both strength and endurance training to lose weight and improve your health rather than either type of training alone. In terms of diet pills, to think that you can realistically lose weight while taking supplements and sitting on the couch eating hot fudge Sundays is completely unrealistic–even if the product is endorsed by Jillian Michaels.
