Response to peer review:
Link terms: I was suggested to link terms to my Lifestyle changes section. I have linked the terms obesity, cardiovascular disease, cytokines and adipose tissue. This should make the article easier to comprehend for people who are not familiar with this jargon.
Add images: I tried find images that has a license which allowed for the use on Wikipedia. Although I looked for them on Creative Commons, I have still not found anything worth using. I do not want to add just any random picture of a heart just to fulfill this suggestion. I want the picture to be meaningful and contribute to the conversation of the article.
Expanding the Lifestyle changes section: I do not think I am going to expand on this portion of the article because I already hit on the major points (exercise and nutrition). If I were to add to this, I feel as though I would be rambling for the sole purpose of making it longer, rather than contributing more information.
I have added the "Lifestyle Changes" section in the Cardiac Rehabilitation article.
