(A) Change in proportion of calories consumed after the evening meal between normal-weight (n = 8) and overweight/obese participants (n = 17). The proportion of calories decreased over time in both groups (F[10, 139] = 5.23, P < 0.0001) and the levels of caloric intake differed between the weight groups (F[1, 23] = 6.16, P = 0.02). (B) Nocturnal ingestions per week decreased significantly and at similar rates for both weight groups (F[9, 123] = 8.23, P < 0.0001)..

Further, as shown in Figure 1, normal-weight participants have been found to demonstrate reductions in percentage of food intake after dinner and their number of nocturnal ingestions per week at a similar rate as overweight and obese participants receiving CBT for NES, but they ended with higher symptom levels as a result of this baseline difference.
