While I don't know what such a diet means for hypertension, it sounds pretty poor in terms of nutritional value. You might have less malaise if you ate more fruits and vegetables, and weren't sending your blood sugar on a roller coaster with those two glasses of coke. Two cans of coke supplies over a quarter of the recommended daily carbohydrate intake!
Try eating nuts or seeds as a snack. The protein will help balance your energy levels and the fat will keep you satiated. Look at granola instead of potato chips -- not the top brand ones bars that are just sugar delivery mechanisms, though.
I sleep ~6 hours per night, drink 6+ cups of coffee and 1-2 cups of tea per day, and only rigorously exercise for 25 minutes 2-3 times per month. My daily diet consists of 600+ calories from extra-virgin cold-pressed coconut oil and butter, 2-4 eggs a day, a handful of cherry tomatoes, 1000+ calories from beef/poultry/pork/fish, 400+ cals from hard cheeses (like swiss), a 1/2 pound - 1 pound of vegetables, maybe a handful of mixed nuts, and a whole lot of kitchen spices (including salt!).
I also try to take 5 - 10 minutes a day to do focused breathing/relaxation (i.e. meditation w/o the hocus-pocus).
With the above lifestyle, I have a resting pulse rate of 54, a bp of 122/70, and I have been losing 2-8 lbs a month for the past 18 months while maintaining strength, endurance, and muscle mass levels. Moreover, I feel wonderful!
I turn 30 at the end of the year, so my good results aren't because I am some youthful, exuberant teenager. I actually attribute them to my diet and lifestyle.
Traditional 'healthy' diet (low fat, low salt, high on carbs and grains) is very bad for health.
Your diet seems to be mostly keto (I assume your coffee and tea are sugarless). The diet of ern is very far from keto.
There are two very active community of redditors (keto and Paleo) with very good info on diets and foods that work to have good health, and bibliographies with explanations of why it works.
I like to think of my diet as "early-Neolithic". I am from one of the populations groups with adult lactose tolerance. So, I modeled it on the foods that might be available to what used to be called a "gentleman farmer".
I also recognize that scientific research has made real progress on determining what to eat in the past few years; so, I've also tried to incorporate some of those findings as well.

And really, you should eat breakfast! The first meal of the day has a lot of important effects. http://www.webmd.com/diet/guide/most-important-meal
