Stories of Health Damage caused by Diet & Excessive Exercise

As I come across more people who are health damaged by Keto, Low Carb, Vegan, and just Low Calorie Diets as well as excessive exercise, especially cardio, I just wanted to create a page to share stories of as many people as possible who have been affected, to serve as a warning to others who may be heading down this path. Read on….

Keto/Low Carb – damaged metabolism & more                                                                                   I was on keto then low carb for 10 years, and thought it was fabulous. I lost all the weight I wanted to, I found it easy to do, I was never hungry, made all these fabulous fat bombs desserts. But then one day I realised my body was falling apart – body temperature was really low 35.3C (95.5F), pulse low – 60 bpm and I would always have cold hands and feet, even though I lived in a hot climate – so super low metabolism. My hair started falling out and blood tests showed I had high cholesterol, high fasting blood sugar (heading towards pre-diabetes), low white blood cells (low immunity), weight started to come back on and I had about 10 other symptoms pointing to hypothyroidism. I now eat in a way that supports my health and metabolism, I’m feeling so much better, all health markers are improving and weight is right where I want it to be as well. – Kristy A. 

Keto/Low Carb “Bulletproof” & years of hard core intensive exercise                             Coming from keto/low carb “bulletproof” and years of hard core dieting and exercise, I lost 22lbs but I lost my energy, my period, strength, power, joy, personality, sleep, glow, hair amazing skin, muscle, time with friends, youth (I’m 23 feeling 73) and re-developed eating disorder behaviour. My liver enzymes are elevated and the bad cholesterol is high and I’ve re-developed hypoglycemia. Super sensitive to heat and cold. Blood flow sucks. Teeth are in worse shape. Skin issues on my feet. Skin issues period. Irregular hunger cues.

Already 1 month full on Ray Peat style and my body is not going crazy through the night as much, I received my period after almost a year, my fun loving personality is coming back, I am calm and can enjoy my meals. I also feel no need to over train. I’m able to stay up past 6 pm most days, and enjoy time with friends better, and work the next day with energy most of the time. Digestion is more normal. I can get up and move around or clean the kitchen right after a meal without feeling like my stomach is going to explode from all the non starchy veggies. Oh I feel like I can even go play like a kid after eating. Good signs. Time to make memories and live life to the fullest…free from my ED and dieting! – Amanda Lajcaj

Many diets & low calories led to Hashimoto’s                                                                                     I did a week long intestinal cleanse (virtual starvation) that turned into two years of veganism, followed by tubal ligation that screwed my hormones and developed into Hashimoto’s Thyroiditis.  I then spent several years living abroad where the food quality wasn’t great (lots of polyunsaturates) so I didn’t eat regularly or the right quantity.  Getting lots of sun helped keep the damage at bay for a while, but when I returned to the UK the effects hit me at full force. I’m heading in the right direction now with Dr Ray Peat’s work, but it’s a long, slow process of undoing all the damage. – Sophie

Paleo, Intermittent Fasting and Keto Cycling                                                                            Health and fitness has always been a focus and passion of mine. So, when I came across the paleo diet with claims of being most in line with our ancestral human nature, I dove right in. From there I learned about the “danger” of carbs, which produce “toxic” insulin. And before long I was intermittent fasting and on a cyclical ketogenic diet.

At the time, I could rattle off all the supposed reasons why these were the best dietary practices – they improved mitochondria respiration, improved insulin sensitivity, increased autophagy, reversed chronic conditions, and on and on. I truly thought that I understood why these dietary practices were ideal for our health.

But, while I was extremely lean on these diets, I began to have experience symptoms. I wasn’t making improvements in the gym and didn’t have the energy for workouts, I had to study more for my classes because I wasn’t processing information as well, my libido was almost nonexistent, I had high cholesterol, and I had an unquenching craving for carbohydrates.

It was around this time that I came across the work of Dr. Ray Peat, which completely changed my perspective on health. It also led to the realization that I didn’t truly understand the physiological effects of low-carb/ketogenic diets and intermittent fasting, and that instead I was simply attracted to the claims that were being made about those dietary practices.

As I dug deeper and developed a stronger understanding of physiology, the picture became clear, and I was able to change my dietary and lifestyle practices to fall in line with what our physiology dictates is healthy. As that happened, the many symptoms I experienced on the low-carb/ketogenic diets and intermittent fasting were resolved and I felt far better than I ever had before. – Jay

Keto/Low Carb & circuit training                                                                                                         I’ve never been particularly over weight but I have had a few health problems growing up. My periods had never been regular; I could go two or three months without one. I was diagnosed with irritable bowel syndrome because I often had stomach pains that couldn’t be explained, and I was told I had poly-cystic ovary syndrome.

After reading an article, I found the low carb diet and after a rocky start on it, I started to feel better and had loads of energy. I thought it was the best thing ever and started to preach to everyone how great it was and how they should all follow it.

Fast forward two and a half years and I still thought things were pretty great. My stomach pains cleared up and to top it off, I discovered circuit training. I loved it! I felt strong and empowered, never mind that every time I left the place I had a weird throbbing headache.

I remember attempting some kind of test to be able to do a certain class. My competitive spirit is, how shall we put it, erm, fierce!! I remember having nothing left to give but pushed myself to the end and literally fell down on the finish line. I felt sick and was shaking like a leaf but the others were laughing so I laughed too, it was funny right? When I got home my boyfriend said I looked ill. I couldn’t sleep all night. I had no idea what was wrong. I had terrible anxiety.

Then I read another article about how being a fat burner is not such a good idea. When I really thought about it, I actually hadn’t felt brilliant for some time. My sleep had gradually been getting worse; I had been feeling tired, and I had totally lost interest in my PhD – which I previously loved doing. I had terrible anxiety attacks, I was always cold, I had insomnia and my hair was falling out. I just thought if low carb really was that bad for you, then that could explain all the health issues I was having.

So the next steps trying to undo all this damage got worse, before it got better. I ballooned from size 8 to size 18 trying to re-carb myself and get my metabolism back up. Also no exercise was recommended, as this was contributing to the metabolism decline.

It took 2 years to start to feel better and while in my recovery my weight isn’t budging fast, my skin is getting less dry, my hair is the shiniest it’s ever been, I have periods regular as clockwork, and my sleep is better than ever. It’s a work in progress but at least now it’s on the right track.   – Karen
