GLP BRIEF
This week: Updated guidance for GLP-1 users having surgery, why strength training matters during weight loss, simple Day One habits, pill-swallowing tips, and small routines that are easier to stick with.
Today's Number
24 HOURS
For some patients at higher risk, their medical team may recommend avoiding solid food for 24 hours before a procedure and using clear liquids instead. This is not a standard requirement for everyone taking a GLP-1.
- Why it matters: GLP-1 medications can slow stomach emptying, which may leave food in the stomach longer than expected.
- The key: Current guidance favors an individualized approach rather than automatically stopping GLP-1 medication.
- Remember: Never change or stop your GLP-1 on your own. Follow the instructions from your surgical and anesthesia team.
Top Story
Having Surgery? Tell Your Anesthesia Team About Your GLP-1
If you have a procedure coming up, add one important step to your checklist: Tell your surgical and anesthesia team that you take a GLP-1.
GLP-1 medications can slow stomach emptying. During anesthesia or deep sedation, stomach contents can potentially enter the lungs if they come back up.
It's Not One-Size-Fits-All
Earlier guidance focused on automatically stopping some GLP-1 medications before surgery. Newer guidance takes a more personalized approach. Your medical team may consider:
- Your current dose
- Whether your dose was recently increased
- Symptoms such as nausea, vomiting, or constipation
- The type of procedure
- The type of anesthesia or sedation being used
What Should You Do?
- Don't stop it on your own: Your healthcare team should decide whether any medication changes are needed.
- Tell them early: Let your surgical team know about your GLP-1 when your procedure is scheduled.
- Mention your symptoms: Tell them if you're experiencing significant nausea, vomiting, constipation, or unusual fullness.
- Plan for diabetes care: If you're taking a GLP-1 for Type 2 diabetes, your team may need to consider how any medication or eating changes could affect your blood sugar.
GLP Brief Takeaway: Don't make the medication decision yourself. Make sure your care team knows you're taking a GLP-1 so they can create a plan that's right for you.

Why Strength Training Matters During Weight Loss
When you're losing weight on a GLP-1, the scale isn't the whole story.
Weight loss usually comes mostly from body fat, but some lean muscle can also be lost. Getting enough protein and doing resistance training can help support muscle retention while you're losing weight.
Think Protein + Strength
- Protein provides the building blocks your body needs.
- Strength training gives your muscles a reason to stay strong.
- Together, they can support muscle retention and physical function during weight loss.
How to Build Your Routine
- Start with strength: Aim for 2–3 resistance sessions per week.
- Add easy movement: Walking, cycling, or swimming can complement your strength work.
- Don't overdo it: Consistency matters more than exhausting workouts.
- New to strength training? Start with chair squats, wall push-ups, resistance-band rows, or light dumbbells.
GLP Brief Tip: You don't need a perfect workout plan. You need a routine you can keep doing.
From the Community
- When Your Dose Feels Too Strong: If a dose increase makes you feel overly full, smaller portions and slower eating may be easier to tolerate. If you have severe or persistent nausea, vomiting, or pain, contact your healthcare provider.
- Having Trouble Swallowing Pills? Try leaning slightly forward as you swallow rather than tipping your head back. Take the pill with water and follow the medication's instructions. Never crush or split a tablet unless your pharmacist or prescriber says it is safe. (If swallowing food or liquids is difficult, talk with a healthcare professional.)
- When the Scale Stops Moving: Weight loss is rarely perfectly linear. A short-term plateau doesn't necessarily mean your medication has stopped working. Look at trends over several weeks rather than judging progress by one day's number.
GLP Brief Tip: Look at the trend, not one weigh-in.
Newbie Question
Q: Where should I inject my weekly GLP-1 dose?
A: Injection sites depend on the medication you're taking. Common sites listed for several injectable GLP-1 medications include the abdomen, thigh, and upper arm. Follow your medication's instructions for where and how to inject, and rotate sites as directed. Avoid injecting into areas that are irritated, bruised, scarred, or painful.

Myth of the Week
Myth
"I need to completely overhaul my diet on Day One."
Reality
Overnight overhauls create stress and cause burnout. Focus on small upgrades instead: add protein to breakfast, drink water steadily, or take a short walk after meals. Consistent micro-habits compound over time.

GLP Brief Cheat Sheet
- NUMBER TO REMEMBER: 1.2–1.6 g/kg — Some clinical reviews suggest this range may help support muscle retention during active weight loss, especially when combined with resistance training.
- BIGGEST MISTAKE TO AVOID: Forgetting to tell your surgical and anesthesia team that you take a GLP-1.
- HEALTHY HABIT: Keep easy protein options ready—Greek yogurt, eggs, cottage cheese, pre-cooked poultry, or protein shakes.
- QUICK REMINDER: Sip fluids steadily throughout the day instead of trying to drink a large amount all at once.
Bottom Line
Successful weight loss on a GLP-1 isn't about doing everything perfectly. Focus on the basics: eat enough protein, do regular strength work, stay hydrated, listen to your body, and keep your healthcare team informed. Small habits repeated over time can matter more than a perfect plan you can't maintain.
YOUR CHALLENGE THIS WEEK
Pick one meal each day and add a dedicated protein source for the next seven days. Don't change anything else. One meal. One upgrade. Seven days. See how it feels.
