Infant formula is 98% ultra-processed oil, sugar, and protein powder. Homemade infant formula can help a child thrive in many of the same ways as breast fed babies.
Lessons on Health From The China Study:
Author T. Colin Campbell, PhD, makes the following argument to support a vegan diet:
- Avoiding animal proteins cuts a woman’s estrogen and progesterone levels
- This delays the onset of puberty, stunts her growth, and leads to early menopause
- Which may reduce her risk of breast cancer.
Therefore, he argues, mothers should put their daughters on a strictly vegan diet. Skeptical? Me too.
Maybe you’ll be convinced if you hear it straight from the horse’s mouth. From page 164 of The China Study:
“The ability of dietary factors to control female hormone levels has long been known in the research community, but a recent study was particularly impressive. Several female hormones, which increase with the onset of puberty, were lowered by 20-30% (even 50% lower levels for progesterone!) simply by having girls eight to ten years of age consume a modestly low-fat, low animal-based food diet for seven years….These results are extraordinary because the were obtained with a modest dietary change and were produced during a critical time of a young girl’s life, when the first seeds of breast cancer were being sowed. These girls consumed a diet of no more than 28% fat and less than 150 mg cholesterol/day: a moderate plant-based diet. I believe that had they consumed a diet devoid of animal-based foods and had they started this diet earlier in life, they would have seen even greater benefits, including a delay in puberty and an even lower risk of breast cancer later in life.”

Saved my life
I would like to thank you for literally saving my life. Back in February, I had to be hospitalized while on vacation in Phoenix with an A1C of 11% and had to start taking 2 types of insulin and 2 other meds. I read the Fatburn Fix in April, and followed the program to a tee, and I’m down by 15 pounds, 6.8 A1C, and only one once weekly diabetes medicine. Prior to reading the book, it was almost impossible for me to lose weight as a diabetic.
I feel free
For the last month, I have really been reading all labels on everything. I have completely remove those 8 oils you talk about. I must tell you, I feel great! I have more energy and I am now 197 lbs (have always been around 205 to 210lbs). I eat potatoes with real butter, grass fed steak, pasta with the right toppings. I eat everything! I seem to crave less sugar. I love it!
I feel so much better
I had terrible aches and pains everywhere in my body, my hands, shoulders and knees. I feel so much better and the way I feel is motivating me every day! Thank you

My allergies disappeared
The biggest difference for me (and a surprising one) is that my allergies have almost completely disappeared! This is a big deal for me, because I’ve had allergies most of my life and they have often affected what I do which is a teaching music in [a public school district]. In general, I feel much better and have more consistent energy throughout the day.
Heart Palpitations have Stopped
I’ve lost 20+ pounds (also fasting 16-24 hours daily) and haven’t had palpitations except for one occasion — I had a mini bag of Fritos for the first time in July. And, I feel better now on a daily basis than I ever did all through college.

Lost 20 lbs I could never shed
I love your Fatburn Fix! Has helped me so so much! I have had the dreaded weight all my life - 20 or so pounds I could never shed. I have lost that now. I only eat 2 meals a day lunch and dinner with a glass of milk or cappuccino around 4 to hold me over. No snacking and not bad oils. It has been the key to unlocking my fatburn. I work out in the am and believe I am burning fat for energy not from food!
I feel great
My waist is four inches smaller. I feel great and many of the minor aches and pains that I had (knees and lower back) are gone. Also, my muscle tone is amazing, even though I have not increased my workout routine.

Highly recommend The Fatburn Fix
Dr. Shanahan has had a significant impact on my practice of medicine. I am known as a Low Carb Doctor, but I never really appreciated the negative effects of processed seed oils on the health of my patients. I highly recommend The Fatburn Fix to my patients and have a loaner copy in my waiting room. It is amazing how quickly blood sugars and overall health improves with cutting seed oils. It is not just about the carbs!

Dr Campbell’s Diet May Someday Be Found to Lower Risk For Some Types of Breast Cancer, But At What Cost?
Cambpell’s argument is an example of the thinking that has guided nutrition science for the past half century. Clearly Dr Colin Campbell cares deeply about preventing breast cancer. But to make the statements above is, in my medical opinion, not just scientifically premature (given the lack of consideration of the larger picture here) but also potentially harmful.
Are there ANY OTHER Implications of Reducing Estrogen and Progesterone Levels?
Reproduction is a big part of life. In fact, it’s one of the life’s defining characteristics. However, based on his own statements, it appears Dr Campbell believes that the timely onset of the hormones associated with puberty is not in any way essential to health or well-being but as ugly by-products of an animal-protein inclusive diet that serve only to put women at risk of breast cancer. As a woman, I feel torn by the fact that his stated intention is to reduce the chances of breast cancer, which noone is a fan of, but at the same time I find myself cringing a little at the idea of my teenage self or somebody’s daughter being included in his population-wide experiment to stall puberty for up to six years.
Though Dr Campbell doesn’t explicitly say this in his book, I suspect he would argue is that what’s unnatural is a young woman entering puberty at the tender age of 9-13 (the currently accepted normal ranges for the initial signs of puberty i.e. breast bud development), I suspect he would go on to argue that what is normal, natural, and healthy is for a girl to enter puberty between the ages of 15-19. It’s one thing to want to reduce breast cancer rates. But to do so at the expense of female development seems to me a bit extreme. Besides, we know hormones don’t have anything to do with some types of breast cancers. We also know that there are other ways to reduce breast cancer risk that don’t endager overall health.
Are there any potential downsides to a woman reducing her hormone levels to the lowest possible range?
The Worst Case of Hormone Deprivation I have EVER Seen
I have personally seen what may be the worst possible outcome of following an all plant-based diet: A stolen womanhood.
A young lady came to see me in clinic after suffering 8 compression fractures in her spine from severe osteoporosis after following an all plant diet for less than a decade. When I got her DEXA report (DEXA is the name of the most common bone-density test) my jaw dropped. The definition of osteoporosis is a T score of -2 or lower, which is not uncommon in 80-year-olds. Her’s was the first T-score I’ve ever seen so low: -8. She was 31.
When we first met, she was in tears. She was scared. She was in pain (those fractures hurt!) She had not had a period in something like five years. She was depressed. She couldn’t work, couldn’t support herself, and had to move back in with her mom. She couldn’t hike or do any of the things she loved. The hunch in her spine was hard not to notice, and she hated that. Yet, even after all this suffering, she was terrified at the prospect of re-introducing milk into her diet because of years of unwavering faith in Dr Campbell’s recommendations. The China Study was, after all, “the most comprehensive study of nutrition ever conducted.”
It says so right on the cover.
As a human being and an animal lover, I deeply empathize with people who have decided to go vegan in order to ensure they in no way support the horrible practices now endemic in the meat industry. I agree that those practices, and the companies that promote them, should be eliminated. As a scientist, however, I cannot countenance linear thinking when a more comprehensive, holistic consideration of the dynamic nature of physiology and growth is called for. As a physician dedicated to disease prevention and health promotion, I am angered and frustrated when a person comes to see me riddled with the debilitating complications from following any ill-conceived medical advice. Vegans have seen images of animal cruelty and said “This should never happen.” When I see a woman who’s quality of life has been taken from her, a woman who is suffering, I say “This should never happen.”
We’ve got to be able to figure out a way to prevent both.
