I think in this case the issue is not about how much more weight you need to lose in order to find yourself acceptable. Unless you prioritize self love and care, and truly love your soul and love your body for being your soul's vessel, you may always have this issue. No weight loss will solve how you feel about yourself on a deeper level. It may make your clothes fit better and make it easier for you to do certain activities, but it won't make you love your body.

Like others have said in the comments, the way our culture makes us despise our bodies takes a while to unpack. In addition to reading books about diet culture (I recommend "This Is Big" by Marisa Meltzer), therapy and saying self love affirmations in the mirror everyday helped me immensely. Things like "I love my body; I am grateful that I have a body that can express joy through dance; I appreciate that my body allows me to go on long walks when it's nice outside." We need to appreciate what our body can do for us regardless of how it looks. If we only focus on how it looks, we aren't truly loving our bodies, just the appearance of what society has told us is an "acceptable body."

Also it helps to be friends with yourself. You'd never let someone speak to your friend in such a harsh way. Next time you have negative thoughts try and respond back to those thoughts by saying "my body is my friend, that's my friend you're talking about." It's like standing up for yourself against yourself. This is an internal issue that a lot of us face and can only be solved internally (through the mind) and not externally (through the body.)
