Reva’s pattern of bragging about fasting suggests her insecurities about her weight and appearance: she seems to want the narrator to praise and validate her efforts, or (perhaps preferably) to insist that she is already thin and doesn’t need to diet. It’s a foreboding sign, meanwhile, that the narrator feels “less and less attached to life” the longer she hibernates. It suggests she has no interest in repairing her old life and the issues that made it so unbearable to her—instead, she entertains the wishful thinking that she can sleep and repress these issues until she can “disappear completely, then reappear in some new form.”
