Figure 4. Change in energy intake estimates for gestational weight gain.

Association between gestational weight gain and change in energy intake (Change EI), calculated as calculated energy intake during pregnancy minus measured baseline total daily energy expenditure for each individual in the present study (A, n = 54), and for intervention groups in lifestyle intervention studies for pregnant women with obesity (B, by first author). The association is defined by measured data in this study and defined as Change EI [kcal/d] = 1.178 ± 0.108*GWG [g/week] –225 ± 46; R² = 0.70, in which Change EI is change in energy intake relative to early pregnancy total daily energy expenditure and GWG is gestational weight gain during the second and third trimesters. The regression line is presented with 95% confidence intervals. REC, recommended gestational weight gain (170–270 g/week).
