You are not a
smaller man.
Almost every weight-loss tool was designed for a body you do not have. This is the correction.
MyFitnessPal wasn’t written for this moment.
Generic trackers were built in a world before GLP-1s. They assume willpower is the variable. They reward calorie deficits and punish “cheat days.” They treat a plateau as a personal failing and a week of nausea as an opportunity to skip meals.
You are on a medication that removes your appetite whether you want it removed or not. You are trying to protect muscle you cannot feel disappearing. You are noticing side effects that come and go with a rhythm no one has told you is real. A generic calorie counter is, at best, the wrong tool. At worst, it is actively unhelpful, rewarding the thing you should be worried about.
Four things every study glosses over.
Gastric emptying slows in the luteal phase. Progesterone shifts hunger and cravings. Many women report their “bad GLP-1 weeks” line up with the back half of their cycle, and no app knows to ask.
Rapid weight loss triggers telogen effluvium for a meaningful portion of GLP-1 users, showing up around month three to six. It resolves, but only if the body has the protein and micronutrients to grow the hair back.
Women enter adulthood with less lean mass than men and lose it faster in a deficit. A medication that suppresses appetite without protecting protein intake can quietly convert muscle to loss.
GLP-1s are not approved in pregnancy. Tirzepatide can reduce the effectiveness of oral contraceptives. The window between stopping and conceiving is a conversation for your prescriber, but the app can at least raise it.
We ask different questions, so we give different answers.
The calculator asks about your cycle, and then actually uses the answer: resting metabolism and appetite both move across a month, and a flat daily number hides that. It treats protein as a floor rather than a line on a macro wheel, and it sets that floor before carbohydrate and fat are given any room. It asks what this week has actually been like, because vomiting or diarrhoea should suspend a deficit rather than be noted and ignored.
It is quiet. There is no account, no email wall and no notification when you skip breakfast. Nothing you type is stored, so there is nothing for us to sell or lose. You come back when a number changes, and the rest of the time it leaves you alone.
Four things we will never be.
There is no house plan, no forbidden list, and no colour-coded traffic light on your plate.
We do not diagnose and we do not prescribe. Where a figure needs a clinician, the tool says so and stops.
There is no timeline of other women’s losses. No leaderboard. No one to perform for.
GLP-1s work over months and years. The numbers here are built for the long version.
Fertility & GLP-1s, the one-minute version.
GLP-1 medications, semaglutide, tirzepatide, liraglutide, are not approved for use during pregnancy. Most prescribers recommend stopping the medication and waiting at least two months before attempting to conceive.
Tirzepatide can also reduce the effectiveness of oral contraceptives, and a barrier method is often recommended during titration.
These decisions belong to you and your prescriber. A website is not the place to make them, but it is the place where we will remind you to have the conversation.
The numbers women on a GLP-1 were never given.
Free, no email, your answers never stored. Two minutes, and it shows you its working.
