Destined to be fat forever, even with GLP-1?
I have been on a GLP1 (tirzepatide) since March 2026. I have titrated up every month and am currently on 10mg, today is shot day and I’m deciding if I am going up to 12.5mg or not. I have been overweight my entire life, but bc I have also basically been on a diet my entire life and I enjoy walking/running, I have been able to avoid gaining as much weight as I easily could. My highest weight was 220 lbs as a 5’8 woman, I got down to around 160 a few years ago through extreme dieting but my “normal” weight is mid 170s, although the last 3 years I have gone between 155 and 185 (155 was bc I absolutely starved myself for 5 weeks bc of family stuff and I wasn’t eating anything). I am currently at 174. When I started tirz in March I was at 182. So I have lost a grand total of 8 lbs in 4 months, although I have basically been around this weight for 7 weeks. I am beyond frustrated with my body. I definitely have appetite suppression and at this point I don’t really have any GI symptoms anymore (at least more so than usual, since I have IBS). I don’t think tirz is not working, I think it is more my body. I just can’t figure out what it needs to lose weight. When I’m in a major calorie deficit, I don’t lose weight. When I track calories and eat what I think I should be, I don’t lose weight. When I eat more than what I think I should be eating, I sometimes see a small change in the scale so I think I am not eating enough, so I eat a little more daily than what I want and then guess what, I gain weight. I walk every day 2-5 miles (bc of my dog, so I never miss a day). My food intake is what would be considered a “diet” to other people – no sweets or very limited/infrequent, small breakfast if anything, light lunch, no snacking, healthy dinner. I see other people eating a sandwich every day for lunch and think “my god if I had a sandwich every day for one meal plus other stuff in a day, I would be a million pounds”.
I am desperate for advice. People will say I am not overweight enough to be on a GLP bc I am not “fat enough”. I have an apron belly and haven’t been able to wear pants my entire life bc all my fat is stored in my stomach and I’m so sick of it. I gain weight so easily. I gained 25 lbs in 5 weeks last fall when I said f it I am done depriving myself (I was still only eating what I think is a normal diet for other people and I was still working out). I tried to lose it for 4 months but after having not lost one pound that’s when I got on a GLP. I want to get to 150 (so 25 lbs down) and I really don’t know what I am doing wrong. I eat right, I do cardio, I am on a high dose of GLP and still the scale stays the same or goes up lately. I have been to a dietician. I have done intermittent fasting. I have done 5 small meal/snacks and a normal meal a day. I have starved myself. Nothing works. I was diagnosed with Hashimotos in Spring of 2025 and have been on levothyroxine since then with stable levels until 2 weeks ago. My TSH was high so my dosage was bumped up. But I just need some advice or tips or criticism on what I am doing wrong and what I should be doing differently. Or is my body just effed bc of my thyroid issues? Does your body have a weight it wants to stay at naturally and nothing you do will change that?
