This book has some good advice but it is also advice you'll find in most of the self-help health books out right now. Basically, your lack of energy comes down to: eating too much sugar, not getting enough sleep, exercising too much (that's a relatively rare one and one that's kind of nice to hear), having too much stress, not eating enough fiber, eating too much junk, having a toxic environment, not taking care of your gut health, etc. The answer is in getting enough sleep, eating TONS of fiber and vegetables, cutting out sugar, etc. She provides a WTF plan (I forget what this stands for? something with whole foods?) that is plant-based for the most part.
I appreciate that Shah is a medical doctor, a mother, and someone who's worked with thousands of patients doing exactly this. I liked all the case histories of tired women who couldn't lose weight or feel better and how they turned things around. I also really appreciated the fact that she stressed again and again that overdoing "good" things was just as bad for you -- running marathons and exercising nonstop without rest days, sacrificing sleep, etc. There is a big focus on stress management and self care. I got very sick with covid last spring/summer and learned the hard way that my lifestyle was far more deadly than I thought, even though I ate all natural and organic, cooked from scratch, avoided chemicals, was a relatively healthy weight, etc. I was chronically sleep deprived, stressed, fueled by coffee and "healthy" carbs, and my immune system absolutely failed me. I used serious changes like prioritizing healthy sleep, meditation, sunlight, tons of water, breathing exercises, gentle exercise, laughter and self care to help heal my blood pressure, heart, lungs, kidneys, muscles, joints, nerves and mental health (going keto also helped me personally), so I know firsthand that this stuff matters. I've read it lots of other places in the past few years, but that's not to say it's not well said here.
One note-- modern health books either promote plant-based (vegan or vegan-like) or very-low-carb (keto or keto-like) diets as a modern lifesaver. I've used both plans in my life to regain my health and both were very helpful for me. This one is the plant-based route, but it has lots of good information no matter how you eat. There's also quite a lot of very specific information about tests to run, supplements that can help, little things that make a difference, the truth about "adrenal fatigue" and more.
I read a temporary digital ARC of this book for review.
