When food replaces something unrelated to food. People who eat to fill their lives with something missing, which is not needed for nourishment. When food becomes a fixation, a worshiped thing, something, which takes the place of what we need to do, rather than withdraw into satisfying a feeling of emptiness. This seems to be gluttony, self serving, rather than being proactive. The sin is not measured in pounds, rather what we avoid by eating as a substitute.

My wife was diagnosed with Polycystic Ovarian Syndrome (PCOS) and Endometriosis at the age of 12.
This combination causes her body to produce testosterone at an increased rate, to the point that it doesn't have anywhere to go.
It absorbs into her body fat, increasing the lipid chemical bonds to the point that the body requires about 5 times as much energy to metabolize them as it would normal fat cells.
Thus, she has never been able to consistently lose weight except by starvation, even as a champion swimmer in high school.
Plus she's large-framed anyway.
She will never be anywhere near what body-type nazis call "fit," but it is in no way her own fault.
On the flip side, I ate like a horse all through high school.
I was in marching band, and my metabolism was still in high gear.
My first year of college it bottomed out on me without me realizing it, and still eating like a horse I gained 30 pounds in a few months.
Now I'm 65 pounds overweight, going to school and working, with barely enough time in between to spend time with my wife, to say nothing of working out consistently.
Have I been careless? Yes.
Have I been lazy? Yes.
But never has eating become the end-all of my pleasures.
