Skinny Book Review: “The Sirtfood Diet” by Aidan Goggins & Glen Matten
I just want to review the Sirtfood Diet book. I personally did not find anything beneficial, compelling, or new in this book. I personally think the book should be avoided. Here are my reasons why:
The authors claim that there are 20 “Sirtfoods” that help us lose weight and build muscle mass by eating them. They also claim that these foods help to give the same benefits as intermittent fasting. Some examples of sirtfoods include red wine, extra virgin olive oil, walnuts, strawberries, parsley, red onion and rocket.
The plan consists of two phases:
1. Phase 1: three days, where you drink two green juices and one sirtfood meal. Maximum calories is 1000 for three day. You then have four days where you drink two green juices and two sirtfood meals. Maximum calories is 1500 for four days. You can have your last meal by 7pm at the latest. The average calorie per day for the first 7 days is 1286.
2. Phase 2: You then have a 14 day maintenance phase where you don’t count calories, but you have to eat three sirtfood meals per day (they gave recipes and state the days of the week you can eat each of the different meals), one sirtfood green juice and one-two sirtfood “bite snacks”.
Assertions about the diet by the authors
• The claims about how good this diet is and the fact you can lose 7lbs in 7 days, is based on one trial, involving 39 people, that was done in a health club in Chelsea, that has its own restaurant. The restaurant meant the authors were able to prepare all the meals for the participants to eat, and blend the juices for them.
• Their justification for why their diet is good is built on why it’s “better” than intermittent fasting. In justifying their diet, they make assertions about the effects of intermittent fasting that are either just dismissive assertions, or they are completely inaccurate, in the sense that the very opinion they are proclaiming has been disproven by clinical trials, conducted Dr Krista Varady, who wrote the book Every Other Day Diet and is the scientist leading on modified fasting trials.
• They often quote the amount people lost, after they take away the weight of the muscle that they gained. As most people will not be able to take such a measurement, I found this measure was not particularly helpful for the average person. Therefore, I find it misleading that they repeatedly say people can lose 7lbs in 7 days.
• I personally would not be able to mentally survive on two green juices and a meal that is largely a salad for more than one day, let alone three, or even seven, and I would not be able to stop eating at 7pm on such a regimen, still fall asleep, wake up the next day, and function at work. The lack of carbohydrates would seriously affect my ability to mentally function at my peak.
• I would not personally be able to stick to a diet that restricts what I can and can’t eat for at least 21 days.
• I am sceptic as to whether this plan has anything to do with these two “sirt foods” or whether weight loss can be achieved through ANY plan that consisted of any low carb diet, especially one that contained only green juices, and plant based meals, with an average calorie of 1286 calories per day for a week.
