There was a recent study in the Journal of Applied Physiology, where they took a cohort of 96 obese people and started them on different exercise regimens, as well as a targeted 30% deficit in daily calories.
They were either slotted into four different programs, as explained on this writeup:
All subjects performed their exercise programs three times a week for the same length of time and at the same intensity (51 minutes at 50 percent intensity during weeks 2-5; 50 minutes at 60 percent intensity in weeks 6-14; 60 minutes at 60 percent intensity in weeks 15-22.
What they found was that the weight loss was the same, regardless of activity, as written by the research team:
"The present study shows that, when adhered to alongside a hypocaloric diet, different exercise training programs (endurance, strength, or their combination) or the following of physical activity recommendations are equally efficient in terms of improving body weight and body composition variables in obesity management."
Given that there has long been debate about the "best" exercise to lose weight, how can I as a fitness professional use this information to help the people that I work with?
