A Reddit user asked whether losing 30 kg (about 66 pounds) in 15 months is realistic. They’ve made an Excel plan to drop from 100 kg to 70 kg, which works out to about 2 kg (4.4 lb) per month, and they’ve just started four days ago while taking Mounjaro. They want to know if the goal is practical. Mounjaro is the brand name for tirzepatide. It’s a prescription drug that acts like natural gut hormones that help control appetite and blood sugar. In plain terms, it tricks parts of your body into feeling less hungry and can slow how fast your stomach empties, so people often eat less. It’s not a vitamin or a fat-burning pill you buy over the counter — it’s a medicine that doctors give for type 2 diabetes and, more recently, for weight loss in some people. What the evidence shows so far: clinical trials of tirzepatide have produced substantial weight loss for many participants. In those studies, people who took the drug along with lifestyle advice often lost significantly more weight than those taking a placebo. But the trials are structured, supervised, and include many people over set time frames. Real-world results vary: some people lose a lot, others less. The Reddit post is an individual plan and not a study, so it doesn’t tell us how typical the outcome will be. Losing 2 kg per month is a modest and generally achievable pace for many people, especially when combining medication with diet and activity changes. Why it matters: if realistic, 30 kg over 15 months would bring this person from obese (grade 2) down to a healthier weight range, which can improve blood pressure, blood sugar, joint pain, and overall energy. A steady pace of weight loss also tends to be easier to maintain than very rapid drops. For people already using medications like tirzepatide, a structured plan, medical follow-up, and support (nutrition, exercise, behavior changes) increase the chance of success and safety. Friends or family supporting someone through this can make a big difference. Important caveats and risks: prescription drugs like Mounjaro have side effects — common ones include nausea, diarrhea, constipation, and stomach discomfort — and rarer but serious risks exist. The medication should be prescribed and monitored by a clinician, especially if you have other health conditions. Weight regained after stopping medication is common unless lifestyle changes stick. Individual responses vary, and an online plan or Excel sheet can’t replace personalized medical advice. Pregnant people, those with certain pancreatic or thyroid issues, or people on complex medications need special care. Finally, aiming for steady, sustainable loss is safer than extreme calorie restriction or unproven supplements. Bottom line: A goal of about 2 kg per month is reasonable for many people, and using tirzepatide can help—but do it under a doctor’s supervision, pair it with lasting lifestyle changes, and be realistic about side effects and what might happen when the medication stops.
