dietrecommender.jl's Introduction

DietRecommender.jl

Create a diet with minimum calorie intake while fulfilling all recommended micro- and macro-nutrients. Using USDA's food composition database and linear programming, it finds a personalized diet given your age, sex, weight, and food preference. You can exclude specific foods or complete food categories. It is also possible to exclude nutrients from constraints.

It makes sure that your intake of the following nutrients is within the recommended range while minimizing calories: Calcium, Carbohydrate, Choline, Copper, Fluoride, Folate, Histidine, Iron, Isoleucine, Leucine, Lysine, Magnesium, Manganese, Methionine+cysteine, Niacin, Pantothenic Acid, Phenylalanine+tyrosine, Phosphorus, Potassium, Protein, Riboflavin, Selenium, Sodium, Thiamin, Threonine, Total Fiber, Tryptophan, Valine, Vitamin A, B6, B12, C, D, E, K, and Zinc.

Currently, the minimum calories of a diet that fulfills all recommended nutrients is much more than the recommended calorie intake. I am not sure why this happens. Possibly it is a result of recommended daily intake values, which cannot be fulfilled without taking too much calories. I welcome any comments about this issue.

Example

using DietRecommender

your_age = 22
your_sex = "male"
your_weight = 70 # in kilograms

diet_ids, diet_names, diet_amounts, m, status, objval, yval = get_diet(your_age, your_sex, your_weight)
Optimization status: LOCALLY_SOLVED 

Calorie intake: 5054

dietrecommender.jl's Issues

Querying data Error

I keep getting this error. I tried to open the file vs code points to edit it, but it seems its readonly and is a package.
