Changes in body weight (kilograms) for control (C), OFC, T, and OFT females from birth to 59 wk of age. Beginning at 14 wk of age, a subset of control and T animals were overfed (OFC and OFT). Weights were taken at weekly intervals up to 39 wk and at 2- to 4-wk intervals thereafter. The vertical black line indicates when overfeeding began. The horizontal gray bar indicates the period of twice-weekly P₄ sampling. The arrow indicates the time when a detailed cycle characterization was undertaken.
