Macrocodex - Guaranteed weight loss or weight gain within 2-3 weeks, beating GLPs for weight loss! https://macrocodex.app/ 17,000+ users already.

Back in time, many people used to say, "I am genetically predisposed to fat or underweight" All of them were proven wrong by macrocodex's method.

No matter if your metabolism is slow or fast, most people will see guaranteed results!

tech stack: flutter and rust

I see the claims, but I don’t see any evidence supporting them. Could you share what you’re basing the guarantee on? Do you have any publicly available data showing that your app delivers guaranteed results and outperforms GLP-1s? I searched and couldn’t find anything supporting those claims.

I know you work for MacroFactor, but when will you guys publish the datasets you used to benchmark your algorithm? https://macrofactor.com/algorithm-accuracy/

Greg Nuckols Macrofactor's benchmark metrics therefore depend on internal data that isn't disclosed or independently verifiable.

So the published accuracy claims don't tell us much. It's like a student saying, “I scored 99% on a test,” but not showing anyone the test questions or their answers. You have no way to independently verify whether the score actually reflects how well they perform.

The number might be completely accurate, but without seeing the benchmark dataset, there's no way for anyone outside the company to reproduce or properly evaluate the claim.

But for Macrocodex, we do not charge people any money, and people can read the reviews and even the algorithm details!

Our effectiveness claims are based on our own data from 17,000+ users and independent user reports in our group, consisting of 2,000+ members already!

Well, I know you work for Macrofactor, but we are not interested in producing useless posts with colorful charts.

Do you have any publicly available data showing that your app delivers guaranteed results and outperforms GLP-1s?

Yes, our group has thousands of members and where people can join the group through the Macrocodex app, they'll see Macrocodex users outperforming GLP users.

Greg Nuckols can't even do math well. Look at their subreddit, people are always having issues with their app.

As macrocodex is beating macrofactor by a long shot, many people are realizing that Greg Nuckols's science is more about marketing than results and evidence!

Do you remember the Hussain and Solomon controversy of Jeff Nippard, one of the top MacroFactor promoters? And the PhD controversy of Mike Israetel?

MacroFactor charges $72 a year and spends a lot of money paying influencers to promote the app, so it’s not surprising that you see so many submarine posts about it.

Very soon, everyone will realize this!

The basis of these apps is pretty simple: you have to adjust your calorie target based on changes, you have to re-calculate as you go.

What I've found is that tracking activity via calories burned is horribly unproductive as there are large variations on how many calories were "burned" depending on the app, device and activity. Are there any scientific studies on how to calculate calorie burn for any activities? Anything in a controlled environment to understand something simple like adult walking 1 flat mile at 3mph. It seems like this would be really hard to nail down compared with say average calories in an apple. Anecdata: as soon as I stopped tracking activity, the scale started moving.
