This little known secret has been used by bodybuilders to achieve astounding results, including healthy weight loss when necessary. (more…)

Weight Loss Strategies for Strength Training
For years we have been told to diet the excess fat from our bodies and throw in some fast walking to hasten the process. The trouble with this is that the low calorie restricted diet would throw the body into starvation mode, with the body holding onto the fat and using precious lean muscle tissue for energy. (more…)

Can Low-Fat And Low-Carb Advocates Agree On These 20 Areas Of Commonality?
In response to my four-part interview with Dr. Dean Ornish this week, I decided to compile a list of 20 areas of commonality between low-fat and low-carb supporters about diet and health that came out during the interview. Here's what… (more…)

Seven Keys to Permanent Weight Loss Success (Part 4 of 4)
During a recent seminar that I conduct, participants explored the concept of just how powerful the mind is and how this relates to losing fat. After a serious of powerful exercises, they were asked to create an action plan based on what they learned in order to successfully lose fat and keep it off. The result of this workshop was seven keys that addressed what most diet programs or weight loss systems do not: the fact that fitness starts inside. (more…)

Validity of air-displacement plethysmography in the assessment of body composition changes in a 16-month weight loss program
ObjectiveTo compare the accuracy of air displacement plethysmography (ADP) and dual energy x-ray absorptionmetry (DXA) in tracking changes in body composition after a 16 month weight loss intervention in overweight and obese females.
Methods:
93 healthy female subjects (38.9 ± 5.7 yr, 159.8 ± 5.6 cm, 76.7 ± 9.9 kg, 30.0 ± 3.4 kg/m2) completed a 16 month weight loss intervention. Eligible subjects attended 15 treatment sessions occurring over the course of 4 months with educational content including topics relating to physical activity and exercise, diet and eating behavior, and behavior modification. In the remaining 12 months, subjects underwent a lifestyle program designed to increase physical activity and improve eating habits. Before and after the intervention, subjects had their percent body fat (%fat), fat mass (FM), and fat-free mass (FFM)) assessed by DXA and ADP.
Results:
Significant differences (p ? 0.001) were found between DXA and ADP at baseline %fat (46.0 % fat vs. 42.0 % fat), FM (35.3 kg vs. 32.5 kg) and FFM (40.8 kg vs. 44.2 kg) as well as at post intervention for %fat (42.1% fat vs. 38.3 % fat), FM (30.9 kg vs. 28.4 kg) and FFM (41.7 kg vs. 44.7 kg). At each time point, ADP %fat and total FM was significantly lower (p ? 0.001) than DXA while FFM was significantly higher (p ? 0.001). However, both techniques tracked %fat changes similarly considering that there were no differences between the two means. Furthermore, a Bland-Altman analysis was performed and no significant bias was observed, thus demonstrating the ability of ADP to measure body fat across a wide range of fatness.
Conclusion:
At baseline and post weight loss, a significant difference was found between ADP and DXA. However, the results indicate both methods are highly related and track changes in %fat similarly after a weight loss program in overweight and obese females. Additionally, the mean changes in %fat were similar between the two techniques, suggesting that ADP can be translated to its use in clinical practice and research studies as DXA currently is used.
