Is fasting okay with GLP-1s?

Like, twenty years back, I had a good 50 pounds to shed. So I went on a mission. I found that skipping meals was *my* thing. I'd eat less when I finally ate. My doc, who wanted me skinnier, even asked if I was dieting! I lost weight QUICKLY. He didn't know I was fasting, and thought I was sick or something. I went from chubby to feeling great in under a year. Now that I am on zep, I feel full longer and have lost a lot of weight using fasting. I wonder why the medical community does not advise against this way to lose weight now that there are GLP-1s. It seems being overweight is worse than fasting. Is there anything else to consider?
 
Well, I'm not an expert on fasting, but dropping 45 pounds in 8 months isn't what I would call rapid weight loss. That sounds like a perfectly healthy pace. If your doctor back then had issues with that, I wonder if they knew what they were talking about.
 
Fasting isn't necessarily bad for you. It's more about *how much* you're fasting. The main problem with losing weight fast is you might lose muscle. But exercise and getting enough protein can help offset that. I'm no doctor, but the risks of being seriously overweight outweigh any possible negatives of GLP-1s. Obesity causes tons of diseases. GLP-1s haven't been linked to any of those. So, yeah, any doctor who thinks losing 45 lbs in 8 months is too fast isn't someone I'd trust.
 
I might be doing my Tirzepatide thing too intensely. I started at 23 stone in July and now I'm 19 stone 8lbs in October. That's over 3 stone! I'm on 5mg. I'm like you, I don't eat till afternoon, like 2-4PM then I eat again later. Usually it's veg, chicken and rice. I heard your liver processes weight loss and you can get liver damage or gallstones. So I need to think about it, but it's hard to get more calories without junk.
 
I don't like fasting worrying about low blood sugar etc. I think small healthy food choices spread out throughout the day is better. Aiming for 1-2 pounds a week weight loss seems good.
 
Thanks, everyone! It's been years since I saw that first doctor. My current one is happy with my weight loss and wants me to keep it up. I figured being so heavy was harming me so I had to do something. I appreciate the encouragement!
 
Nutritionists usually recommend small, frequent meals as the healthiest option. One problem with fasting is blood sugar spikes. While on GLP1, fasting is easy, but you gained the weight back before, suggesting it's not the best way to lose and maintain. The best approach is healthy choices and sustainable patterns. As we age, fasting becomes harder, we need frequent fuel, can't eat as much at once, digestion changes, and many meds need to be taken with food. Just my opinion, though! Also, great username!
 
I tune out when people start preaching about fasting. Like, I'm fat because I overeat. If I could just casually choose to not eat, I wouldn't be overweight. It's like, 'Hey, I see you're on fire. You know what works for me? NOT burning!'
 
You've been losing about 1-1.5lb a week. That's a good, healthy rate. I lose around 2lb a week. I don't fast, but I eat two meals a day - breakfast and dinner. I only snack on fruit between meals. With Tirz, it's easy to wait, unless my hormones are acting up. I used to graze constantly before GLP1s. It probably helps make fasting easier. My doctors are happy. I'm watched by multiple teams because I am a cancer survivor, so I think they would say something if they were concerned.

Now that I have been using ZEPBOUND for a year I have lost over 50 pounds. I lost this weight by fasting. I am not hungry and feel fuller longer when I do eat. I don’t hear any medical professionals advising against losing weight in this way.

You're using something that curbs hunger and slows digestion – just not eating isn't a long-term solution. You need fuel for energy. Now you should change your eating for the right fuel – food that helps you. Don't just starve. Eat food that benefits you. Your goal isn't starvation (your body will adapt). Make those fewer calories count. Protein and nutrients keep you strong. Now you can change your mindset. Make food your friend, not your enemy.
 
Wow, I'm inspired! Someone on another site went from 231 lbs to 198 lbs in 5 months using a GLP-1. Goal is 175! Clothes are fitting better!!
