The myth of the starting dose


GLP BRIEF:Weekend Note


This week: You’re taking a GLP-1, but still feel hungry. Does that mean it isn’t working? Not necessarily. Plus: a new study shows lower health costs with a catch, a single drug targeting three hormones, and one trick to stop eating on autopilot.

THE 10-SECOND TAKEAWAY

Expected your appetite to vanish on week one? If you’re asking “Why am I still hungry?”—don't worry yet.

Starter doses just help your body adjust. Early hunger doesn't mean the medicine isn't working.


THE BIG QUESTION

Why Am I Still Hungry on My First Dose?

You start taking a GLP-1 and expect food to instantly lose its appeal. Instead, you're standing in the kitchen thinking about dinner.

Here’s why: starter doses get your body used to the medicine—they rarely deliver the full effect. For example, Zepbound starts at 2.5 mg weekly for four weeks before moving up.

That first month is just a transition. Still feeling hungry or having cravings doesn't mean the medicine is failing.

4 things to keep in mind

  1. The first few weeks are just the beginning. Your results can look completely different down the road.
  2. Hunger does not vanish forever. The goal is not to eliminate hunger completely.
  3. Taking more is not better. Moving to a higher dose too fast raises your chance of getting sick.
  4. Do not judge too early. Give your treatment plan time to unfold.

What should you do instead?

Instead of only asking yourself, “How hungry am I right now?”

Start paying attention to these four questions:

  • How satisfied do you feel after a meal?
  • Are you eating because you feel hungry, or just because it is mealtime?
  • How are your daily energy levels?
  • Are your habits changing, even if your hunger feels mostly the same?

If you are thinking about changing your dose, stick to your schedule and talk with your doctor first.

The part people rarely mention

Sometimes the first big change is not losing your appetite.

It is much quieter than that.

You are halfway through a meal you automatically ordered, cooked, or grabbed... …and suddenly you think: “Wait. I don't actually want this.”

That sounds like a small moment. It isn't. Sometimes the very first sign of progress is simply noticing what you are doing with food.

RESEARCH WATCH

Health Costs Went Down. But There Is a Catch.

A new study looked at 15,843 adults over age 55 who had extra body weight and a related health condition. All of them were taking tirzepatide (the active ingredient in Mounjaro and Zepbound).

Researchers compared them to a similar group of people who were not taking the drug.

The result sounded big: health care costs were 25.4% lower for the tirzepatide group between months 12 and 18.

Most of those savings came from fewer emergency room visits and hospital stays. Another part of the study showed people spent about $607 less per month on medical care.

But here is the catch hiding in the fine print: The researchers did NOT include the cost of the medicine itself. They only tracked general medical spending, not the overall cost of treatment.

Also, this was an observational study. That means it found a link between taking the drug and lower medical costs, but it does not prove the drug caused the drop. And because the study only looked at tirzepatide, these results might not apply to every GLP-1 drug.

Why this matters

The real question is not just: “Do GLP-1s save money?”

It is: “Can spending less money on emergency care eventually offset the high price of the medication?”

We do not have a clear answer to that yet.

FROM THE COMMUNITY

“I Caught Myself Halfway Through a Pastry I Didn't Even Want.”

A reader recently shared a story about buying a pastry after work. It was not a special treat—it was just something they always did out of routine.

A few bites in, they stopped. Not because they were forcing themselves to stop, and not to be "good."

They just realized: “I don't actually want this.”

It sounds like a tiny moment, but it is actually a big deal. They did not suddenly gain super willpower. They simply caught an automatic habit in the act.

That is often how changing your relationship with food starts. The first win is not always changing what you eat. It is catching what you do without thinking.

You do not always have to fight a habit. Sometimes, just noticing it is enough.

WAIT, WHAT?

What If New Weight-Loss Drugs Target More Than One Hormone?

Most people have heard of GLP-1 by now. But researchers are currently testing new medicines that target three different hormone signals at the same time.

One of the most talked-about new drugs is retatrutide. It targets three hormones that control hunger and metabolism:GIP + GLP-1 + glucagon

Why use three? Scientists want to know what happens when you turn on three different hunger-control pathways at once instead of just one.

Researchers are also keeping a close eye on safety as tests continue. In one early trial, a small number of people had temporary spikes in liver enzymes (proteins that can show liver stress). However, average liver levels were normal by the end of the study.

That does not mean the drug causes liver damage. It just means scientists are watching every detail as they test it.

When it comes to new medicines:

  • New does not mean bad.
  • New does not mean proven.
  • It just means we are still learning.

5-MINUTE WIN

Try the 10-Second Pantry Pause

The next time you reach for an unplanned snack, do not automatically say yes or no.

Just pause for 10 seconds and ask yourself three questions:

  1. What am I feeling right now? (Hunger? Habit? Boredom? Stress?)
  2. When was the last time I ate?
  3. What would actually satisfy me right now?

Then make your choice. If you are actually hungry, eat.

The goal is not to starve yourself. It is simply to notice whether you are choosing to eat or just running on autopilot.


YOUR TURN

GLP BRIEF CHEAT SHEET

  • Number to Remember: 25.4% — Medical costs dropped by 25.4% for tirzepatide users in a new study (though the price of the drug was not included).
  • Mistake to Avoid: Raising your dose faster than your doctor prescribed.
  • Practical Rule: Do not judge how well the medicine works based on your first few weeks.
  • One Surprising Idea: Your appetite can change before your daily habits do.
  • One Thing to Try: Take a 10-second "Pantry Pause" before reaching for a routine snack.

THE BOTTOM LINE

Feeling hungry on your starting dose can be frustrating.

But do not assume those first few weeks tell you the whole story.

Often, the very first change is not that you stop thinking about food. It is that you start noticing your habits around it.

The snack you grabbed out of boredom. The meal you ordered out of routine. The pastry you suddenly realize you do not actually want.

Those moments are easy to miss. Don't miss them.

Be well,
