Energy balance

The improvements in LDL particle size and VLDL mass resulting from weight loss are primarily driven by the reduction in body mass index (adiposity) rather than the method of weight loss (exercise vs. diet).

For improving LDL particle size and reducing VLDL, the method of weight loss (exercise vs. diet) matters less than achieving the weight loss itself. Both approaches yield similar benefits for these specific markers when the amount of weight lost is the same. However, you should still exercise because it provides additional HDL2 benefits that diet alone does not.

GoodSupportsHIGH confidence
Most of the mean differences in lipoprotein changes between exercisers and controls and between dieters and controls can be attributed to weight loss... Adjustment for body mass index change... eliminated the significance of the exercisers'... increase in LDL peak particle diameter... and their 7-month small LDL decrease.
