The Genesis of Scooby's AI Custom Meal Planner

Custommealplanner started as a simple javascript tool on my fitness website scoobysworkshop.com. In 2015 I spent a year of engineering time and expanded it into a complex meal making machine driven by the USDA food database. It was a great tool but the effort for me to keep it running and maintained was too much of a burden for my ideal retirement so I offered to give it to anyone who would make a substantial donation to a 401(c)3 charity of their choice to prove they were serious and not just going to turn my software into a supplement sales device. No takers so I just shut it down. Pandemic hit, AI revolution, suddenly in 2024 its a whole new world for fitness tools and I got excited. I used my two weeks of recuperation time from my shoulder replacement surgery to write the next generation meal planner one handed (literally). Traditional computer science techniques work perfectly for choosing the foods in a meal, its just math. Math to calculate metabolic rates. Math to calculate weight loss or bulking gain, and math to pull foods out of a database and find their macros. Where both my previous meal planners fail and all legacy meal planners fail is in taking that list of ingredients and creating a tasty recipe and that is something AI is really, really good at! This meal planner combines the best of both worlds, the solid science of traditional databasae driven software to create reliable and accurate lists of ingredients with the imagination of AI to create the recipe.

Its totally free, so what's the catch?

Unlike my previous version of custommealplanner, this one is 100% free because I wanted to keep it simple for both you and me. You have dozens of passwords and subscriptions, the last thing you need is one more recurring charge. I retired 25 years ago and the last thing I want to do in my retirement is process a credit card refund for $2.99 because someone doesnt find my meals tasty. Just bookmark this page and come back when you want to make another meal plan, easy peasy lemon squeezy. Note that although this website is free there is a donate button which is just to help cover hosting costs and the cost of the chatGPT back end requests to generate the recipies. If donations dont cover costs I will place google ads. If you value this website being ad-free, consider donating.

Why Scooby's Custom Meal Planner is best for athletes/bodybuilders

CustomMealPlanner was written by athletes, for athletes. Competing bodybuilders, triathletes, runners, and men's physique competitors. We provide the optimal nutrition for you no matter how active you are or what your goal is. We take the guesswork out of both bulking and cutting. The last thing you want to have to do as a powerlifter or bodybuilder is to do a panic starvation diet at the last minute to make your weight class because you will lose all kinds of muscle. With the bodyfat charts provided with every meal plan you can see exactly when you will achieve your target bodyfat and get sixpack abs.

Not for average people

For 90% of people, this is not the best meal planner for you. If you just want tasty meals that let you lose a few pounds then you will be frustrated by the lack of ingredient choices here so consider using myfitnesspal, noom, or one of the dozens of meal planners that will let you eat anything you want and just tally the macros. This meal planner is for people who have athletic performance as a top tier goal so I only include foods that are appropriate for them.

Known Issues/Bugs

  1. FRUIT. There are currently no fruit choices, I am still waffling on the best way to include them - either as their own food category or to include them as a carb choice.
  2. ChatGPT AAargh! Pulling my friggin hair out so if you can help, please message me on IG. I cannot find any good *current* documents to describe how I can call the openai API from php. I found an out of date doc which used guzzle but it does not work with the current api. I need a "for dummies" version because dealing APIs are NOT my forte. In the meantime, just copy the text in ChatGPT section of your meal plan and paste it into the chatGPT prompt.
  3. Speed If you notice this meal planner loading slowly, please let me know. I am experimenting with cloud LAMP computing and chose a cheap option
