There’s really no right or wrong rate of losing. You’ll lose at your rate. Your weight won’t be falling off you - no 100lb a month losses like On My 600lb Life cause you’re not 600lb+
Not sure what stage you’re at yet but you won’t really start to feel your restriction until you are eating solid food (not purée or soft) & the nerves that were damaged during the surgery are more fully healed. Plus you’re likely still eating quite small portions so you’re restriction doesn’t need to warn you that you’ve eating too much. The first time you eat too quickly, too much or eat something that sits too heavily in your tummy you’ll feel that tightness across your chest.
The effort you’re putting in is what will make you more successful with your weight loss this time. We used to fail to lose weight &/or maintain a lower weight in the past because we never dealt the reasons we were driven to eat and we didn’t permanently decide to eat more nutritious foods & reduce the amount of food we ate.
Anyone can lose ‘too much’ just by being too restrictive in their diet & eating too few calories but ‘too much’ is individual & personal. As long as you’re happy & healthy & can live the life you want all us good. I lost way more than I thought I would be able to but I’m very happy at my weight, am in good healthy & enjoy my life.
Good luck.
