  Figure 1. Histogram of percent total weight loss (%TWL) at 2 y after laparoscopic sleeve gastrectomy. Patients were divided into eight groups according to %TWL (every 5% of TWL). Black dotted line indicates mean %TWL (29.9 ± 11.0%)

  Figure 2. Comparison of 2‐y metabolic remission rates among percent total weight loss (%TWL) groups. (A) Patients were stratified by %TWL into five groups (≤14.9, 15.0‐19.9, 20.0‐24.9, 25.0‐29.9 and ≥30.0). Diabetes complete remission rate was 57.1% in the ≤14.9% group, 53.9% in the 15.0‐19.9 group and more than 80% in %TWL ≥20% groups. Remission rate of dyslipidemia in %TWL ≤14.9% group was 17.7%. The remission rate of hypertension was lower than the other metabolic remissions. (B) Receiver operating characteristic curve of %TWL at optimal cut‐off level of diabetes complete remission. At the cut‐off level (20.8%), sensitivity was 86.2% and specificity was 52.7%

  Figure 3. Prevalence of mental disorders stratified by percent total weight loss (%TWL). (A) Patients were divided into eight groups according to %TWL (every 5% of TWL). Relationship between frequency of mental disorders and %TWL was a U‐shaped curve, and the trend was significant using Fisher's exact test (P = .0046). (B) In patients with %TWL <15%, the frequency was 46.9% and significantly higher than in those with %TWL ≥15% (P = .0101). (C) Frequency in patients with %TWL ≥45% was also significantly higher than in those with %TWL <45%

  Figure 4. Changes in (A) body weight and (B) daily calorie intake in patients with percent total weight loss (%TWL) <15% compared with %TWL ≥15%. In patients with %TWL <15%, significant weight regain was observed from 1 y after laparoscopic sleeve gastrectomy (LSG) (mean body weight was 99.8 kg at 1 y and 106.2 kg at 2 y, P = .0002). In patients with %TWL <15%, daily calorie intake at 2 y after LSG was significantly higher compared to %TWL ≥15% (2012.4 vs 1339.2 kcal/d, P < .0001), and a significant (P = .0486) increase in daily calorie intake from 1 y (1666.8 kcal/d) to 2 y after LSG (2012.4 kcal/d) was observed
