I had heartburn when I started eating really unhealthily and putting off exercise around the time before I went vegan. Because I didn’t know what I was doing at first I dropped a ton of weight, then gained some of it back when I discovered the array of processed vegan junk food.

I rarely get it now (despite eating super spicy foods constantly) but when I do it’s after I haven’t been active for awhile—in other words when I start getting fat.
