You need not only 1,500 mg Na but to increase your K to 3,800 mg. In other words do the DASH. My record patient wt loss is 140 lbs.

The lowfat, low sodium DASH diet, often used to help reduce high BP, recommends no more than 2300 mg sodium per day or, for even stricter control, no more than 1500 mg per day. Check with your MD about the right diet and daily sodium intake for you. https://www.nhlbi.nih.gov/health-topics/dash-eating-plan
