Next up for review
is Whole30: The 30 day guide to total health
and food freedom. There are 2
authors; Dallas Hartwig, who is a licensed physical therapist and Melissa
Hartwig.
Introduction
The goal of this
book is to teach you how to reset your health by avoiding all foods that the authors
consider unhealthy for 30 days. After the thirty days are over, you re-introduce
one food group at a time to see how you physically respond to it. You then decide
what you can safely eat and what you should avoid going forward. The book is
422 pages. It is very well written. The authors have a very motivating style of
writing and I enjoyed reading this book.
5 Things I Really Liked About Whole 30
1) I really like
that this book has you strictly limit refined carbohydrates like bread, white
rice, pasta and sugar. I strongly believe that a stable blood sugar is the path
to weight loss and greater health. Avoiding these foods will make it much
easier to maintain a stable blood sugar.
2) I agree with
the authors idea that inflammation is behind most chronic disease.
3) This book provides
a ton of recipes. Cooking for yourself is critical to improving your diet. These
recipes make it much easier to do so.
4) I really like
the meal template. Combining a source of protein, fat and carb at each meal is
critical to maintaining a stable blood sugar.
5) The section on
eating out at restaurants is really well done. Eating meals outside of the home
is a major challenge to anyone looking to improve their diet. This section
gives you some good tips to stay on course when dining out.
5 Things I Didn’t Agree With in Whole 30
1) I do not
understand the recommendation to limit nuts. Nuts have consistently been shown in
the research literature to improve health (References 1 and 2). They are loaded
with protein, healthy fat, fiber, and other micronutrients. They are not in the
slightest bit unhealthy.
2) Similarly, I
don’t agree with the idea that whole grains are unhealthy and promote
inflammation. Whole grains have
been shown in the research literature to reduce risk of heart disease, certain
cancers, diabetes and inflammatory mortality (References 3-6). They are a very
important part of a healthy diet.
3) I also don’t
agree with the recommendations to avoid legumes. Legumes (like beans and
lentils) are nutritional powerhouses. They are loaded with fiber and are an excellent
choice of low glycemic load carbohydrate. They are a very good source of
healthy vegetable protein and are packed with micronutrients. I don’t
understand why the authors would think these are unhealthy.
4) While the book
recommends avoiding some very healthy foods like nuts, whole grains and legumes,
it also recommends some questionable ones. You can eat potatoes and drink fruit
juice on this plan. These foods are very high on the glycemic index/glycemic
load scale and should be strictly limited in order to stabilize blood sugar.
Similarly, coconut
oil, butter and red meat are given the green light as well. These are unhealthy
sources of fat and protein and should be strictly limited.
5) Once the 30
days are up, I feel that the recommendations are a little too open ended. The
authors advise adding one food back at a time and then to see how you feel. After
you add the food back to your diet, you then decide if and how often you want
to have it. I feel like there could have been a bit more guidance about what foods
will promote (or hurt) long term health going forward.
Is Whole
30 Worth Reading?
Absolutely! This book
gets a lot right. The Whole 30 plan limits refined carbohydrates like white
bread, white rice, sugar and pasta. It helps to stabilize the blood sugar by
recommending a source of protein, fat and carb at every meal. I would make just
a few small changes: nuts, whole grains and legumes are very good for you and
don’t need to be avoided. Saturated fats like coconut oil, butter and red meat
should be strictly limited. One last thing, you don’t just want to eat healthy
for 30 days and then add a lot of the unhealthy stuff back in. Although it is
admittedly difficult, the goal is to eat healthy for the rest of your life.
