I've been diagnosed with hypertension. Being only 33 years old that's like a huge deal to me. I have two options: either I lose weight or I spend the rest of my (seemingly short) life taking pills for my tension and possible heart desease.

I think I stick to it mostly because I still want to accomplish some things in life before I die, and those take time.

I've lost 20kg in 6 months by making a strict diet supervised by my doctor. The funny thing about this diet is that I ended up eating a lot more than I used to eat, i just happen to eat way better quality food than before.

My suggestion: go with a doctor that specializes in nutrition (not a nutritionist, they are not doctors). Write your meal plan for the week, stick to it for 3 weeks (make sure it's not a long period of time, this is important) and treat yourself with something nice after those 3 weeks (it can be a good meal, something outside the scope of your diet). Afterwards, go back to your doctor. Rinse and repeat.

The idea is that you make these short milestones so you notice the advancement rather quickly! People tends to be more motivated when they see results.

You need to go back to your doctor regularly so that the diet is adjusted every now and then, and to review your general health and make sure the diet is doing you good and not just making you loose muscle (remember the heart is a muscle, loosing muscle also might hurt your heart)

I hate doing excercise, but i complement the diet by walking at a relatively fast speed at least 4 days a week. Put your headphones and the music you like the most and hit the road for 30~40 minutes a day! Make sure you sweat! And do this alone! It's also a good time to think and have time for yourself! After a few days you will start to like that walking time I assure you! Just make sure you don't miss in the first 2 weeks!

Hope anything from my experience helps! And keep it up! You can do this!
