They're marginally better than refined sugar but still concentrated calories with little protein. Use sparingly — 'natural' sugar is still sugar.

Worth knowing

On a GLP-1, protein first and modest portions matter more than any single food rule. Adjust to how your stomach feels.

When to check with your doctor

This is general information, not a prescription. Your dose, your other medicines and your medical history all change the picture — message your ZIVOLABS doctor before making any change to how you take your medication.

The diet that makes it work

Medication handles your appetite; what you eat decides whether you lose fat or muscle. Build every plate around protein first, then vegetables, then a modest portion of grain. Roti, dal, paneer and rajma make hitting your protein target easy here; the watch-outs are rich, ghee-laden gravies and stuffed parathas — choose one roti and lean on the paneer and dal. Spread protein across the day rather than one heavy meal, favour whole fruit over juice, and treat sweets and fried snacks as occasional rather than daily. Three litres of water a day keeps constipation and fatigue away — both are usually under-eating or under-drinking in disguise.

How GLP-1 medicines actually work

GLP-1 (glucagon-like peptide-1) is a hormone your gut releases after you eat. It tells your brain you're full, slows how fast your stomach empties, and helps your body release insulin when blood sugar rises. {b} is an engineered, long-lasting version of that hormone: where your natural GLP-1 is broken down in minutes, the medicine keeps working for about a week. The result is that you feel satisfied sooner, stay full longer, and the constant background 'food noise' quietens — so eating less stops feeling like a daily battle of willpower and starts feeling natural.

What to expect, week by week

  • Weeks 1–2: You start on the lowest dose. Appetite begins to dip; some people feel mild nausea or a headache as the body adapts. Weight barely moves yet — that's normal.

  • Weeks 3–4: Food noise drops noticeably. The first dose step-up usually happens around week 4, which can briefly bring side effects back before they settle.

  • Months 2–3: This is where steady weight loss shows up — often 0.5–1 kg a week. Trial data show about 5–7% of starting weight gone by 12 weeks.

  • Months 4–6: The trajectory is clear: roughly 10–12% loss on semaglutide and 14–16% on tirzepatide, alongside diet and activity.

  • Beyond 6 months: Loss continues more slowly toward a new set point, after which you shift to a maintenance dose to hold the result.

Movement that protects your muscle

You don't need hours in a gym, but you do need resistance training. When you lose weight, some of it can come from muscle — and strength work is what tells your body to keep the muscle and burn the fat instead. Two to three short sessions a week (bodyweight squats, push-ups, rows, or weights) plus a daily 30–45 minute walk and a target of 8,000+ steps is enough for most people. Walking after meals also steadies blood sugar and eases the bloating and constipation that can come early on.

Side effects and how to manage them

  • Nausea is the most common, mostly in week one and after each dose increase. Smaller portions, less oily food, ginger or jeera water, and staying upright after eating all help.

  • Constipation responds to three litres of water a day, daily isabgol (psyllium husk), fruit and sprouts, and a short walk after meals.

  • Fatigue usually means you're eating too little — check your protein, iron and B12, and don't cut calories too hard.

  • Reflux eases with lighter, earlier dinners and not lying down after eating; a short course of antacids or a PPI helps if needed.

  • Most side effects are temporary and fade as your body adjusts. Anything severe or persistent — especially intense upper-abdominal pain — should go straight to your doctor.

Common mistakes to avoid

  • Skimping on protein — the fastest way to lose muscle and end up tired with thinning hair.

  • Rushing the dose up — faster titration just means worse nausea, not faster results.

  • Skipping strength training — cardio alone won't protect your muscle or your metabolism.

  • Under-drinking water — behind most cases of constipation, fatigue and headaches.

  • Stopping suddenly once you hit your goal — appetite and weight rebound without a planned maintenance dose.

Frequently asked questions

Do I need to follow a strict diet?

No strict diet, but protein matters: aim for 1.2–1.6 g per kg of body weight a day to protect muscle, and keep fried food and refined carbs modest to avoid nausea.

Is it safe to take long-term?

The evidence to date is reassuring across multi-year trials, including cardiovascular benefit. It's intended for long-term use under medical supervision.

Can I take it if I'm not diabetic?

Yes — GLP-1 medicines are approved for weight management in people without diabetes who meet the BMI criteria, and are used that way safely worldwide.

How much weight can I realistically lose?

Roughly 10–15% of body weight with semaglutide and up to ~20% with tirzepatide over about a year, when paired with adequate protein and some strength training.

Key takeaways

  • A GLP-1 medicine reduces appetite and slows digestion, so you eat less without constant hunger.

  • Protein (1.2–1.6 g/kg/day) plus two to three strength sessions a week protect muscle while you lose fat.

  • Side effects are mostly early and manageable; start low, go slow, and report anything severe.

  • Buy only genuine, doctor-prescribed medication from a licensed pharmacy — counterfeits are a real risk in India.

  • It works best as a supervised plan, with a maintenance dose to hold the result rather than stopping abruptly.
