Mounjaro has been wonderful for me, but you have to do the work, it won’t do it all for you.
I think it’s important to understand how it works so that you can help it along and get the most out of it
How Mounjaro Works
Mounjaro is a dual agonist, meaning it activates two important hormone receptors:
- GLP-1 receptor (glucagon-like peptide-1)
- GIP receptor (glucose-dependent insulinotropic polypeptide)
These hormones help regulate blood sugar and appetite after eating.
1. GLP-1 Effects:
Increases insulin secretion (only when blood sugar is elevated)
Reduces glucagon secretion (which helps prevent high blood sugar)
Slows gastric emptying (helps you feel fuller longer)
Reduces appetite, promoting weight loss
2. GIP Effects:
Also enhances insulin secretion
May help counteract some of the gastrointestinal side effects of GLP-1 drugs
Plays a role in fat metabolism and insulin sensitivity
By mimicking both GLP-1 and GIP, Mounjaro helps:
Lower blood sugar levels
Reduce appetite
Promote weight loss
Improve insulin sensitivity
You can help it along by changing your diet to increase protein, fat and fibre which increases satiety and helps to prevent muscle loss. You should be mindful of carbs and try to ensure that you are choosing complex carbs and eating them with a protein or fat. This helps to reduce blood sugar spikes which can make you feel hungrier. You do need to have a good idea of how many calories you are eating, because to lose weight you need to eat less calories then you use, so some people track everything, others are comfortable approximating, personally I track because I know that if I don’t then I’ll end up over consuming and not noticing.
You can also help by introducing more exercise, strength based to build muscle which increases metabolism and things like a brisk 20 min walk after eating because it helps to break down the sugar from the meal you’ve eaten.
You also need to ensure you are well hydrated, approx 2lts liquid a day because your body uses water in the process of breaking down and removing fat, it also uses it to heal muscles that are sore after exercise, if you don’t drink enough then you will retain water and weight loss will stall.
I’ve lost 5 stone since last September, started as a size 22/24 and today I did up a pair of size 10 jeans.
You can make this work but you won’t lose it all in a month, you have to prepare for this taking a while, the difference with using Mounjaro is that while I still have to work at it, I no longer feel starving hungry all the time, just normal hungry around mealtimes, so it’s so much easier to bear the diet and to keep consistent. Previous attempts it’s like a long slow torture and there’s only so many weeks you can spend every waking moment thinking about food, rumbling stomach, mouth watering and feeling up miserable before you crack and give in. It’s not been painful with Mounjaro so I’ve been able to just steadily chip away at the weight and focus on doing exercise and building stamina.
