Sodium intake is a far smaller problem than total caloric intake, lack of exercise, and lack of adequate sleep.
Don’t eat fast food. Don’t eat frozen food. Shop the perimeter of your grocery store.
Eat mainly animal, vegetable , and fruit.
Move. Try to have fun while moving.
Sleep 8 hours.
I’ll add, don’t eat canned or boxed foods. Eat fresh as much as possible. Do your own cooking. Then you know what’s in the meal.
Except frozen vegetables are fresher than canned and cook up quickly.
