A 60-second walkthrough showing exactly how to get your personalized fiber, protein, fat and timing plan.
Your Personalized Plan
Enter your meal’s carbs (or describe it and let AI estimate) to get your fiber, protein, fat and timing plan instantly.
Why This Approach Works
Backed by nutrition research on viscous fiber, meal sequencing and post-meal movement.
Viscous Fiber First
Psyllium, chia and konjac slow carb absorption — dosed to your exact meal, not a generic amount.
Smart Meal Sequencing
Veg and protein/fat before carbs can cut the glucose peak by 30%+ — we tell you the exact order.
Protein & Fat Targets
Scaled to your carbs, with real food examples so you know exactly what to eat.
Multilingual + AI
Describe any meal in plain language, in your language — AI estimates the rest.

Frequently Asked Questions
How much psyllium husk (isabgol) should I take before a meal for blood sugar?
Most studies use roughly 5–10g of psyllium husk with a full glass of water, 15–30 minutes before a carb-heavy meal. The calculator scales this to your meal: about 1g of viscous fiber per 5g of carbs, capped near 15g, halved if you’re new to fiber. Isabgol is simply the South Asian name for psyllium husk.
Chia seeds before a meal for blood sugar — how much?
Chia forms a gel once soaked, similar to psyllium, and can blunt the glucose rise right after a meal (about 1 tbsp ≈ 4g fiber; soak for 10 minutes first). The evidence here is less robust than for psyllium, though — a 2024 meta-analysis found chia doesn’t reliably improve longer-term markers like fasting glucose or HbA1c, so treat it as a milder, acute-effect option.
What’s the right glucomannan (konjac root) dosage?
Glucomannan is the most potent viscous fiber — 1–3g can match several grams of psyllium. It expands dramatically in liquid, so always take it with a full glass of water, never dry.
Is inulin good for blood sugar spikes?
Inulin (chicory root) is great for gut health but has low viscosity, so evidence for blunting an acute spike is weak compared with psyllium, chia or glucomannan. Treat it as a gut-health fiber, not a spike blocker.

Does guar gum help with blood sugar spikes?
Yes — guar gum is one of the most concentrated viscous fibers available, with strong evidence for blunting post-meal glucose at doses around 5–10g (or ~5g as the gentler partially hydrolyzed form, PHGG). Because it expands so much in liquid, always take it with a full glass of water.

Do fenugreek seeds lower blood sugar?
Fenugreek seeds are a traditional South Asian remedy backed by real clinical evidence: their galactomannan fiber plus other natural compounds can reduce post-meal glucose. Because fenugreek has its own blood-sugar-lowering effect, it can amplify diabetes medications — check with your doctor before combining the two.
Why eat protein and fat before carbs?
Meal-sequencing research shows eating vegetables and protein/fat before carbs can reduce the glucose peak by 30%+ versus the reverse order — the original study measured reductions of up to 37% at 60 minutes. Aim for ~20–30g protein and 10–15g fat with a 50g-carb meal.

Does walking after eating lower blood sugar?
Yes — a 10–15 minute walk starting 10–20 minutes after eating is one of the best-evidenced ways to reduce the post-meal glucose peak, since working muscle pulls glucose from the blood without extra insulin.

Do calf raises after eating lower blood sugar?
Yes, and there is real research behind it. A 2022 study (Hamilton et al., iScience) found that “soleus push-ups” work because the calf’s soleus muscle burns mostly blood glucose and fat rather than its own glycogen — acting like a natural sink that can keep pulling glucose from your blood for hours without tiring. Sustaining this activation cut post-meal glucose spikes by about 52% and excess insulin by about 60% in the original study, though that headline number came from hours of continuous activation, not just a quick set; a smaller 2023 pilot study in people with prediabetes found a short session still reduced post-meal glucose by roughly 32%. How to do it: seated, feet flat with knees at 90°, keep your toes down and lift your heels as high as comfortable, then lower with control; standing, rise onto your toes and lower slowly. Many people do this for 10–15 minutes starting a few minutes after eating. It is a great option if you are stuck at a desk, but it complements rather than replaces a post-meal walk, which still has its own benefits for heart health.
Is viscous fiber absorbed in the large intestine?
Not directly. Fiber survives digestion and travels to the colon, where gut bacteria ferment it into short-chain fatty acids (acetate, propionate, butyrate) – and those are what actually get absorbed into the body. Beta-glucan (oats, barley) blunts glucose spikes mainly earlier, in the small intestine, by thickening the gut contents so sugar is absorbed more slowly; whatever reaches the colon afterward still ferments well and feeds beneficial bacteria. Pectin (apple, citrus) is even more fermentable – it is broken down almost completely in the colon, making it as valuable for gut health as for slowing a spike.
