The Short Answer Nobody Wants to Hear
Last March, a patient named Danielle in Chattanooga told her dietitian she'd swapped her daily two cans of Coca-Cola for two tall glasses of homemade sweet tea. "I figured tea is natural, so it's got to be healthier," she said. When her dietitian, Sarah Moreno, RD, pulled up the numbers together, Danielle was genuinely shocked: her sweet tea recipe packed about 22 grams of sugar per eight-ounce glass. A 12-ounce can of Coke has 39 grams. But Danielle's "glasses" were 16-ounce tumblers, and she poured three or four a day. She was consuming more added sugar than before, not less.
Here's the thing: sweet tea and pop are, metabolically speaking, almost the same product. Both are sugar water. Sweet tea does carry trace antioxidants from the tea leaves (catechins, polyphenols), and that's not nothing. But "not nothing" is doing a lot of heavy lifting when your daily sugar intake from beverages alone is blowing past the American Heart Association's recommendation of no more than 25 grams for women or 36 grams for men.
The honest answer to "is sweet tea better than pop?" is this: barely, and only if you're making it yourself with meaningfully less sugar. A restaurant sweet tea or a bottled brand like Milo's or Gold Peak often matches or exceeds the sugar content of a can of Sprite. If you're choosing between the two for metabolic health, you're choosing between two losing hands.
Why This Question Comes Up So Often on GLP-1 Therapy
About 590 people a month type this exact question into Google. And a disproportionate number of them are in the middle of a weight-loss program, often on GLP-1 medications like tirzepatide or semaglutide. The medication is suppressing appetite, they're eating less, and now they're looking at everything else in their routine wondering what to optimize.
Beverage choices are one of the biggest blind spots. Patients who meticulously track food calories often don't count liquid calories at all. A 2019 analysis in the American Journal of Clinical Nutrition found that sugar-sweetened beverages accounted for roughly 7% of total daily energy intake among U.S. adults. For heavier consumers, that figure climbed to 12-15%.
GLP-1 therapy changes appetite signaling, which makes it easier to eat less. But it doesn't change the glucose spike from a 200-calorie glass of sweet tea. If you're on compounded tirzepatide and wondering why your fasting glucose isn't budging, your afternoon beverages might be the culprit hiding in plain sight.
The Sugar Math, Laid Out Plainly
Let's stop being vague about it.
Check your GLP-1 eligibility
Use our free BMI Calculator to see if you may qualify for provider-reviewed GLP-1 therapy.
Try the BMI Calculator →Typical sugar content per 8 oz:
- Homemade sweet tea (Southern-style): 18-24 g
- Coca-Cola: 26 g
- Pepsi: 27.5 g
- Milo's Sweet Tea (bottled): 23 g
- Snapple Lemon Tea: 23 g
- Unsweetened iced tea: 0 g
The gap between sweet tea and pop is about 3-8 grams per serving, depending on who's making the tea. That gap vanishes the moment you pour a bigger glass, add a refill, or buy a gas station 32-ounce styrofoam cup (a fixture in my home state of Alabama, where I'm pretty sure sweet tea qualifies as a constitutional right).
The boring truth is that unsweetened tea with a squeeze of lemon is the actual healthy swap. Not sweet tea. Sweet tea is soda's polite Southern cousin who shows up in a sundress and does exactly the same damage.
What the Antioxidant Argument Gets Right (and Wrong)
Tea does contain real bioactive compounds. Black tea provides theaflavins. Green tea provides EGCG. Both have demonstrated modest anti-inflammatory effects in cell and animal studies, and a few large observational trials (like the China Kadoorie Biobank study, published in the European Journal of Preventive Cardiology, 2022) have associated regular tea consumption with lower cardiovascular risk.
But those studies looked at unsweetened tea consumed in moderate quantities. When you dissolve a cup of granulated sugar into a gallon of tea, you're adding roughly 770 calories and 192 grams of sugar. Whatever antioxidant benefit the tea leaves contributed is now sitting inside a vehicle that promotes insulin resistance, hepatic fat accumulation, and the exact metabolic dysfunction you're trying to reverse.
It's like putting premium gasoline in a car that has no engine. The fuel quality isn't your problem.
Where This Falls Apart for GLP-1 Patients Specifically
Every published GLP-1 weight-loss trial included a lifestyle component. SURMOUNT-1, STEP 1, and the SURPASS series all paired pharmacotherapy with calorie guidance and physical-activity recommendations. The published results reflect the combined effect: medication plus lifestyle.
Patients who treat GLP-1 therapy as one input among several tend to land closer to the trial averages. Patients who rely on the injection alone and change nothing else, including their three-glasses-a-day sweet tea habit, tend to plateau earlier and at higher weights.
The four most commonly underweighted lifestyle inputs alongside GLP-1 therapy are protein intake, resistance training, sleep quality, and hydration. Beverage choice is really a hydration and calorie question rolled into one. If your primary fluid intake is sweetened (tea, pop, juice, whatever), you're working against the medication.
SURMOUNT-1 reported substantial response variation even within the same dose arm. Some of that variation is genetic. Some is adherence. And some, I'd argue, is the stuff that doesn't get tracked in a clinical trial protocol: the daily sweet tea, the nightly Gatorade, the "just a splash" of creamer that's really four tablespoons.
Practical Swaps That Actually Work
If you like sweet tea and can't imagine giving it up entirely, here's a realistic ladder:
- Halve the sugar in your recipe. Most people adjust within a week. Your palate recalibrates faster than you'd expect.
- Try monk fruit or allulose as partial sweeteners. Neither spikes blood glucose meaningfully. Stevia works too, though some people find it bitter.
- Brew it strong and cold-brew it. Cold-brewed tea extracts fewer tannins, so it tastes smoother without needing as much sugar to mask bitterness.
- Set a one-glass limit. One 8-ounce glass of lightly sweetened tea per day is not going to wreck anyone's metabolic plan. Four 16-ounce glasses will.
For pop specifically: diet soda or zero-sugar options remove the glucose problem entirely. Whether artificial sweeteners have their own downstream effects is a separate (and genuinely unsettled) debate, but on pure glucose and calorie metrics, a Diet Coke is categorically better than a regular Coke or a glass of sweet tea.
When to Bring This Up With Your Prescriber
Any question that touches how your daily intake interacts with a prescription medication is worth mentioning at your next visit. If you're on compounded tirzepatide and your glucose numbers aren't tracking where you and your prescriber expected, a beverage audit is a five-minute conversation that can save months of frustration.
Most telehealth platforms have a messaging channel that produces a response within one to two business days. Use it. "I'm drinking three glasses of sweet tea a day, should I be concerned?" is a perfectly reasonable message.

Frequently Asked Questions
Is sweet tea actually healthier than pop?
Marginally, and only if you make it yourself with substantially less sugar than the traditional recipe. Store-bought and restaurant sweet tea typically contains as much sugar per ounce as regular soda. The antioxidant content of tea is real but modest, and it doesn't offset the metabolic impact of high added sugar.
How much sugar is in a typical glass of sweet tea?
Homemade Southern-style sweet tea runs 18-24 grams per 8-ounce serving. Bottled versions like Milo's or Gold Peak are in a similar range. Most people pour well over 8 ounces, which pushes a single "glass" to 30-45 grams of sugar.
Should I switch to diet soda instead?
From a pure glucose and calorie standpoint, yes. Diet soda and zero-sugar options eliminate the blood sugar spike entirely. The long-term effects of artificial sweeteners remain debated in the literature, but for someone actively managing weight or blood glucose, the swap is a clear net positive.
Does sweet tea affect GLP-1 medication effectiveness?
GLP-1 medications work on appetite signaling, gut motility, and insulin secretion. They don't neutralize the caloric or glycemic impact of what you drink. High-sugar beverages can blunt the metabolic benefits you'd otherwise see from the medication.
What's the best drink to have on GLP-1 therapy?
Water. Then unsweetened tea or black coffee. Then sparkling water or water flavored with fruit. Then diet or zero-sugar beverages. Sweet tea and regular pop sit at the bottom of the list.
Is compounded tirzepatide FDA-approved?
No. Compounded tirzepatide is not an FDA-approved drug. The FDA does not review compounded medications for safety, effectiveness, or quality prior to dispensing. Compounded medications are dispensed under personalized prescriptions through state-licensed pharmacies when a prescriber determines a personalized formulation is clinically appropriate.
