Can lifestyle habits actually raise your GLP-1 levels naturally?

What did @glucosegoddess_ actually say?

The creator laid out three "natural hacks" to raise GLP-1 levels: eat vegetables first, then protein and fat, then carbs; take a supplement containing eriodictyol (she called it "eryocytrin"), the flavonoid that gives lemons their yellow color; and chew food longer. She attached specific numbers to two of these, claiming food order raises GLP-1 production "by up to 38%" and the lemon compound raises it "by up to 17%."

She framed all of this as an alternative or complement to GLP-1 drugs like semaglutide, telling viewers these habits can help them "feel more full, have fewer cravings" and improve glucose levels. The supplement angle is worth flagging immediately: she did not name a product, but she explicitly told viewers to "find a supplement" that delivers eriodictyol daily. That's a purchasing recommendation tied to a health outcome claim, and the evidence behind it is thinner than she let on.

Does the science back this up?

Partially, but the percentages she cited deserve serious scrutiny. The food-order research is real, but the 38% figure is lifted from a small, controlled study that may not reflect real-world eating habits. The chewing claim has some support. The lemon extract claim leans heavily on early-stage research.

On food order: a 2018 study by Shukla et al. published in Diabetes Care found that eating protein and vegetables before carbohydrates reduced postprandial glucose and insulin spikes, and some GLP-1 secretion data exists in related literature. A 2023 Japanese study in Nutrients (Kuwata et al.) looked at macronutrient sequencing and GLP-1 responses in people with type 2 diabetes and found meaningful but variable effects. A 38% increase in GLP-1 is on the high end of what's been reported, and that number appears to originate from a small crossover trial, not a large population study.

On eriodictyol: a 2022 study in Molecular Nutrition and Food Research (Esposito et al.) found eriodictyol stimulated GLP-1 secretion in intestinal cell models and in rodents. The 17% figure she cited likely comes from this or similar preclinical work. As of now, robust human clinical trials confirming this effect at a specific supplement dose do not exist in the peer-reviewed literature.

On chewing: a 2014 study by Smit et al. in Appetite found increased chewing time was associated with higher postprandial GLP-1 and reduced appetite ratings. This is the most credible of her three claims, and it's the one she made no specific percentage claim about, which is telling.

What did they get wrong (or right)?

She got the direction right on all three claims. Eating carbs last does appear to blunt glucose spikes and may support GLP-1 secretion. Chewing more is genuinely associated with satiety signals including GLP-1. The problem is the precision she attached to these claims and the supplement push.

The 38% figure for food order is being presented as if it's a settled, reproducible, population-level finding. It isn't. It comes from tightly controlled research settings, often in people with metabolic conditions, and individual responses vary widely. Presenting it as a universal "up to 38%" boost sells certainty the science hasn't delivered.

The eriodictyol claim is the weakest link. Telling viewers to go buy a supplement based on cell culture and animal data is a meaningful overstep. The human evidence is not there yet. She also mispronounced and partially misspelled the compound (calling it "eryocytrin"), which won't help anyone trying to evaluate the actual research. She deserves credit for not naming a specific brand, but the implicit message is still "go find this supplement," and that's worth pushing back on.

What should you actually know?

Natural lifestyle habits do influence GLP-1 secretion, and that's not pseudoscience. But the gap between "influences" and "clinically meaningful weight loss or appetite control" is enormous. Prescription GLP-1 receptor agonists like semaglutide raise effective GLP-1 signaling by a magnitude that lifestyle tweaks simply cannot replicate. Eating your vegetables first is a genuinely good habit. It will not produce the pharmacological effect of a weekly injection.

If you're experiencing persistent hunger, uncontrolled cravings, or blood sugar dysregulation, that's a conversation for a clinician, not a TikTok comment section. A registered dietitian can help you structure meals in ways that support satiety. A physician can evaluate whether underlying metabolic factors are at play and whether medication is appropriate.

The food-order and chewing habits she describes carry essentially no risk and some real evidence behind them. Adopt them if they work for your life. Be more cautious about adding supplements based on animal studies promoted in short-form video content, regardless of how confidently the numbers are cited.
