MOUNJARO UPDATE | WEEK 1-8 | weight loss so far, side effects, supplements etc...
Our summary
The creator, a UK woman who says she is 4 foot 11 and was classed as obese at the start, gives her eight-week update on Mounjaro. She says her starting weight was 10 stone 12 and her BMI was 30.7 according to the NHS website. She lists her weekly weigh-ins: a 5 pound loss in week one, small losses in most weeks, maintenance in weeks three and seven, and a 3 pound loss in week eight. In total she reports losing 14 pounds, or one stone, which brings her to 9 stone 12 and a BMI of 27.9. She says she is averaging one to two pounds a week.

What else the video covers
She says she is still on 2.5 milligrams and has chosen not to move up a dose. In her experience appetite suppression is strongest for the first three or four days after injecting, and food noise creeps back on days four to seven. She says she is happy with the results and side effects at this dose. She tells viewers to ask their GP or provider about dose changes because she is not medically trained. She also describes the supplements she takes: collagen, a multivitamin with iron, magnesium citrate, and electrolytes, plus vitamin D and calcium from her GP. Some were sent to her by a supplement brand, and she mentions a discount card.
On side effects, she reports constipation in week three but none since week four, headaches that have gone away, slight fatigue, and strong thirst over the last two weeks. She says week eight brought loose bowel movements, which she thinks may have been a stomach bug, since her daughter was also unwell. She no longer tracks calories, prioritises protein, and has noticed less inflammation and bloating. She says she plans another update around the 12 week mark.

- Mounjaro for weight loss, and why Zepbound exists
Mounjaro is tirzepatide approved for type 2 diabetes. Zepbound is the same molecule from the same maker, approved for weight management, and it goes to the same 15 mg. So unlike Ozempic and Wegovy, there is no dose ceiling pushing you from one to the other: the reason people move is coverage and cash price, not strength. Using Mounjaro for weight is off-label and a prescriber's decision. In the one head-to-head trial, tirzepatide beat semaglutide, 20.2% mean body-weight loss at 72 weeks against 13.7%.
- Mounjaro side effects: the label's numbers by dose, the low blood sugar risk, and how tirzepatide compares at weight-loss doses
On Mounjaro's own label, the common side effects are stomach ones and they rise with the dose: nausea in 12, 15 and 18 percent of people at 5, 10 and 15 mg against 4 percent on placebo, diarrhea 12 to 17 against 9, and any gastrointestinal reaction in 37 to 44 percent against 20. Most of it happens while the dose is being raised and fades. Low blood sugar is rare on Mounjaro alone and is mainly a risk when it is added to insulin or a sulfonylurea. Below: the full table, the rare warnings, and why Zepbound's numbers for the same molecule look higher.
- Mounjaro vs Ozempic, and the trial everyone quotes about it
Mounjaro is tirzepatide and Ozempic is semaglutide: different molecules, not two brands of the same drug. Both are approved for type 2 diabetes, and the weight-loss versions are Zepbound and Wegovy. In the one head-to-head trial, SURMOUNT-5, tirzepatide produced 20.2% mean body-weight loss at 72 weeks against semaglutide's 13.7%. The detail almost every page omits: that trial dosed semaglutide to 2.4 mg in people without diabetes, which is the Wegovy range. Ozempic tops out at 2 mg. The famous result did not test Ozempic's dose range.
