Drink lots of water, low-carb diets work but can be rough on the kidneys. Also, watch the diet soda as it can contribute to kidney stones.
Low-carb diets aren’t rough on the kidneys; high-protein diets are.
The general agreement on low-carb diets is “Low carb, high-fat (about 2/3 of your daily calories, if I recall correctly), medium protein”.
I got gout on low carb high protein diets. drink lots of water and black cherry juice.
