Objective: We evaluated whether a 12 - wk dietary behavior modification (D) treatment to decrease energy intake, physical
exercise behavior modification (E) treatment to implement
moderate aerobic exercise, or combined dietary and physical
exercise behavior modification (DE) treatment compared with control (usual care)(C) reduces body weight in lactating women measured at the end of treatment and at a 1 - y
follow - up 9 mo after treatment termination.
The routine
followed by participants in Levine's study included two to three days of
moderate - intensity
exercise, one high - intensity session such as four - by - four interval training, a weekly strength - training session, and a weekly longer session of various types of
aerobic exercise.
