JJ obviously not BBoy but want to comment. There are so many variables. I would state the type of keto diet you have in your head would only help lower your blood pressure. Inflammatory foods can definitely have a big effect but they could be carbs or fat. Keto diets are very often started to lose body fat and good food choices are used and people get leaner so it will only help blood pressure. Obviously if you ate a keto diet full of shit foods it would be bad for blood pressure and everything else. A lot of the foods you are eating now are great. Basically nutrient dense, natural and healthy foods.
Guys who start eating plant based diets void of artificial hormones etc tend to notice a reduction in blood pressure and improvements in all health markers. But you wouldn't have to go vegan as top quality salmon etc could be great sources of protein/fats. I think a keto diet would personally suit you but you have to give it time. Although it's not needed to get your bp lower as you could do by changing things a little, adding cardio and maybe a few supps.
Then comes your fondness of throwing in fairly high doses of adrol or similar pre workout. That is probably not helping matters even if it is 4 times per week
I don't want to throw supps at you but they can really help supplement a good diet. Many get sides from this but carditone is amazing for blood pressure and worth a try. If you didn't want to use that some ubiquinol, hawthorn berry and grape seed extract. NOW Foods do a Blood Pressue Health product that contains 2 of those ingredients. Even if you started with that 1 product and see how you go it could help matters. I would doubt hawthorn Berry and grape seed extract would give you any bad side effects either if you stay within the recommended dose.
