Continuing our series on low-insulin living for 2026, we've seen in Part 1 why the ketogenic diet shines for metabolic health, and in Part 2 why Dr. Benjamin Bikman cautions against Ozempic as a weight-loss shortcut. The good news? You don't need injections to harness GLP-1—the satiety hormone that curbs appetite, supports fat loss, and improves insulin sensitivity.
Dr. Bikman, drawing from his research and daily routine (shared in The Diary of a CEO and his Metabolic Classroom series), champions natural, food-based tools to stimulate your body's own GLP-1 production. These align perfectly with keto principles: gentle, side-effect-free, and sustainable. Here are two standouts he frequently recommends.
Allulose: The Rare Sugar That Acts Like Nature's GLP-1 Booster
Allulose is a low-calorie sugar found naturally in small amounts in figs, raisins, and maple syrup. It tastes like sugar but has negligible calories, doesn't raise blood sugar or insulin, and is mostly excreted unchanged.
Dr. Bikman's lab research shows allulose triggers GLP-1 release in the gut, acting as a powerful satiety signal. In animal studies he references, allulose-rich diets reduced food intake, body weight gain, and improved insulin resistance—mimicking some GLP-1 agonist effects safely. Human data supports better appetite control and metabolic perks.
How it works: Allulose interacts with intestinal taste receptors and cells, prompting GLP-1 secretion. This slows gastric emptying (keeping you fuller longer), reduces cravings, and enhances fat burning. It's keto-friendly—use it as a sweetener in coffee, baking, or drinks to stay satisfied while keeping insulin low.
Yerba Mate: The Tea That Fuels Metabolic Magic
Yerba Mate, the traditional South American herbal tea, is Dr. Bikman's go-to caffeinated beverage (he drinks it daily post-workout and ice bath). His BYU lab has demonstrated it boosts GLP-1 by 40-50% in fasting states, thanks to compounds like ferulic acid, polyphenols, and saponins.
How it works: Ferulic acid is metabolized by gut bacteria into forms that activate GLP-1-producing cells in the intestines (and even fat tissue via bitter taste receptors). This promotes satiety, better insulin sensitivity, fat oxidation, and mitochondrial efficiency in muscle, fat, and liver. Unlike coffee's crash, it delivers steady energy—ideal for low-insulin lifestyles. Dr. Bikman often points to quality brands like those from UFeelGreat for optimal benefits.
By adding Allulose and Yerba Mate to your keto routine, you get natural GLP-1 elevation: brew Yerba Mate hot or iced, sweeten with Allulose, and notice reduced hunger without drugs or downsides.
Collagen Peptides: A Natural Ally for GLP-1 Support and Midlife Wellness
Collagen peptides (hydrolyzed collagen) are highly absorbable protein fragments that go beyond classic skin, hair, joint, and gut benefits—they show emerging promise in supporting natural GLP-1 pathways.
Recent research indicates that specific collagen peptide compositions can enhance the body's own GLP-1 secretion from intestinal cells, helping regulate post-meal blood sugar, promote insulin response, slow gastric emptying, and boost feelings of fullness. For example, certain bioactive collagen peptides (like those studied in clinical trials) have been shown to increase active GLP-1 levels significantly, reduce glucose spikes, and support better glucose tolerance in both healthy and prediabetic individuals. This makes them a gentle, food-derived complement to GLP-1-focused strategies—without the intensity of medications.
For women in their 40s navigating perimenopause, collagen peptides offer extra perks amid hormonal shifts:
- Skin elasticity and firmness — Counteracts accelerated collagen loss (up to 30% in early menopause years), reducing sagging or dryness.
- Joint comfort and bone health — Supports cartilage, reduces aches, and may help maintain bone density.
- Gut integrity — Strengthens the intestinal barrier for better digestion and nutrient absorption.
- Muscle preservation — Provides amino acids to help protect lean mass during any weight management efforts.
How to incorporate: Add 10–15g of unflavored hydrolyzed collagen peptides to your morning smoothie, coffee, or soup daily. Look for grass-fed bovine or marine sources for quality. Brands like Codeage (with Nextida GC for targeted GLP-1 support) or general high-quality options (Thorne, Vital Proteins) work well.
While not a direct GLP-1 mimic like medications, collagen peptides provide a synergistic, natural boost to metabolic balance, satiety, and overall resilience—ideal for midlife hormone-friendly wellness. Always consult your doctor before adding supplements, especially if on GLP-1 therapies.
In 2026, choose empowerment—build habits that support your body's own systems rather than overriding them. Experiment with these, track your energy and cravings, and consult a healthcare provider as needed.
