High blood pressure. And all fast food.

I used to drink regularly on a daily basis, but since I was diagnosed with HBP one year ago I quit drinking too, I don't smoke. But I take things to the extreme.e.g. when I used to drink I could not drink like a gentleman,now since the HBP I quit drinking and stopped taking salt completely and non veg food and all fast food. I take only two pieces of atta roti in the morning and 3 pieces of roti at night with vegetables and have a small portion lunch at noon. O have reduced my weight(lost 8+ kgs in this year span). I was 77kg before and now I am around 67kg,and everyone says I have reduced ALOT,now I want to gain weight as I don't look skinny and sometimes I feel u healthy due to loosing some fat, but I'm afraid to eat salt and other protein related food as I fear it might trigger the high BP. Looking for good advice on future course of action. I regularly take Concor Cor 2.5mg medicine and I have quit alcohol,non veg and other fast food from the past one year and I don't smoke.
