Meal Planner
A simple implementation of meal plan generator by using genetic algorithms. Given a set of available foods with its macro values and a set of target macros (carbs, proteins, fats) the algorithm compute a proper weight of each food to achieve the target macros.
Usage
Usage: java -jar meal-planner.jar options_list
Options:
--debug, -d [false] -> Debug log
--targetCarbs, -carb -> Target Carbs (always required) { Double }
--targetFats, -fat -> Target Fats (always required) { Double }
--targetProteins, -pro -> Target Proteins (always required) { Double }
--plans, -plans [4] -> Number of plans { Int }
--foodFile, -foods [foods.csv] -> Foods file { String }
--help, -h -> Usage info
Carbs, proteins and fats are supposed to be in grams. The foods file must be a simple CSV with the following syntax:
name;carbs;fats;protein
bread;50;3;7
arachids;11;52;26
mermalade;37;0;0
Again, macros are expressed in grams per 100g of product.
The algorithm also assume the following kcal:
const val KCAL_PROTEIN_PER_GRAM = 4 const val KCAL_CARB_PER_GRAM = 4 const val KCAL_FAT_PER_GRAM = 9
Example
Consider the following CSV saved as simple-foods.csv and these macro as target (Carbs: 40g, Proteins: 15g, Fat: 10g)
name;carbs;fats;protein
bread;50;3;7
arachids;11;52;26
mermalade;37;0;0
Run it: java -jar meal-planner.jar -carb 40 -fat 10 -pro 15 --foodFile ./simple-foods.csv.
The algorithm by default produces 4 plans from the best to worst (you can change this by adding -plans option):
