We have to find our own way when we get close to maintenance weight. I had a similar experience, and to keep progressing you need to tweak things to get those final pounds off. What I did was what worked in my situation, but someone else could be opposite of my issue with the same result. You could be over eating, under eating, eating foods that are holding you back (dairy, artificial sweeteners, nuts and nut butters), eating too many hours during the day, exercising too much or not moving enough, drinking alcohol too often, stress, lack of sleep…
It’s also often necessary to re-examine how much you’re eating as you get smaller. Are you a creature of habit? Are you eating till satiety and stopping? Have you tried any fasting, intermittent or extended?
Like you I got to the weight I used to look good at and realized my body was changed too much to look good at that weight. Except for me it was 20-25 lbs because I don’t have the muscle and bone mass I used to. Maybe I also set an easier more achievable goal in my mind starting out and with the power KETO gave me I realized I could do much better. I have adopted this as a lifestyle for health issue reasons. I’m in maintenance mode but my body is still going through recomposition. I still fast and in maintenance have done my first extended fasts in 15 months of KETO. I’m interested in autophagy and life extension and rebuilding my body as best possible.
When you’re close to maintenance you have to shake it up to get the rest off. I had to eat more for a while and during a shorter time window. Other people eat too much out of habit as they get smaller. I was under eating and my metabolism was slowed down. Weight loss was there and all of the sudden stopped while eating at a deficit. You have to figure out your individual situation. Good luck and congratulations on your awesome progress so far.
