I would not be too concerned about losing too much weight. Unless you have extremely rare and serious complications, it is infuriatingly easy to eat more than enough calories to maintain. For most people, avoiding regain is the biggest concern in the long term. I’m about 3.5 years out and I have to be super careful to track my calories and work out every day.
If I weren’t careful to eat low-calorie foods, I could easily gain back a lot of weight. The effects of the restriction wear off over time and I can eat much larger portions than I could, say, 1 year out. Not nearly as much as I could eat pre-surgery (I was a bottomless pit!) but if I were still eating the same high-calorie foods, I would be in trouble.
The only reason I’ve been able to maintain my weight loss so far is because I completely changed the way I eat. Going through the post-op diet progression forced me to reset my diet, relearn how to eat. Now that my restriction has weakened and I can’t rely on my stomach to limit my portion sizes, I have to fill my stomach with low-calorie foods. In some ways it’s easier than before surgery because I’ve retrained my palate and developed good habits, but it is definitely still a struggle every day.
