Chubster is a hipster's take on dieting. Why is the author an expert on such matters? He lost 100 lbs by creating his own 'diet' of changes that fit within his hipster lifestyle. He begins by telling his story of dropping from 290 to 190 lbs. He then details the changes that he made, which was mainly counting calories and eating smarter foods, and adding in bouts of activity. The author includes a lot of research to back up his claims, but it is nothing new, and I'm still not convinced he has the credentials to write a diet book. Nonetheless, I did enjoy the book and found it informative.
The author relied on calorie counting to lose his weight. He claims this is the only equation that matters, citing the professor who lost weight on a diet of mainly Twinkies. While this works for some people, there is a lot of research that suggests otherwise, that sugars and proteins play a larger role in regulating hormones and hunger, especially in women.
He also did not have time or desire to go to a gym or start a regular workout regime, so he found other ways to add activity into his life. Again, this works for some people, but others will not be satisfied with the results and will want or need something more structured. But maybe they aren't hipsters.
I did like the author's frank attitude, telling readers that you have to count calories and you have to do your research about how many calories are in foods and drinks. Basically, he tells readers that you can't be lazy and you're going to need to rely on some tools to help you with this. He mentions a few different ways, such as books, Google searches/websites, and phone apps. He also points out foods that are filling, but not fat or highly caloric.
Obviously this isn't a diet book for everyone, it is geared toward one specific type of person. The audience for this book is 20 and 30 yr old hipsters who haven't cared much about diet, and do not exercise. These are people who just want to lose weight for health and/or vanity, not to become the next P90x spokesman.
