What is mentioned in a couple of these comments about your body's response to external stressors changing how it allocates calories is absolutely true, but it's at the margins. If you're at maintenance caloric intake and ± a couple hundred calories a day, over years this can have an effect. But it's not going to meaningfully impact a 500-1000 calorie/day deficit to the point where you're still gaining weight.

I believe there is a study where people ate at a 25% deficit but had high glucose and still gained weight.

Is this the study you were referring to?

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7898726/

> Effects of moderate sleep restriction during 8-week calorie restriction on lipoprotein particles and glucose metabolism

Because the conclusion starts with,

> In this study, 8 weeks of calorie restriction with and without sleep restriction of less than 90 minutes per day on 5 days with 2 days of ad libitum sleep per week, resulted in similar degrees of weight loss

Let me be clear that sleep deprivation doesn’t seem to be good for your circulating lipoprotien levels or insulin sensitivity based on that study, but they didn’t gain weight.
