The keto diet: “My body moves and feels better than it did 20 years ago”


Mary had tried everything to lose weight but nothing would last. She went from binge eating to counting calories for decades. In her 60s she stumbled upon the Diet Doctor website and tried a keto diet:

Dear Diet Doctor,

This is my story.

I am a 60-year-old female, I live in Grand a Forks, British Columbia, Canada. Today marks seven months since I came across the Diet Doctor site and my life changed.

I was never overweight growing up, in fact, the opposite. I am 5’7” (170 cm) and my weight was between 135-140 (61-63 kg) from late teens until I was about 25 years old. I never gave weight much thought and didn’t notice at first the slow gain, about 5-6 pounds (2-3 kg) a year. After the first 25 pounds (11 kg), I went to Weight Watchers, weighing 167 (78 kg) and had success – I went back down to 140 (63 kg). I didn’t really change how I ate however, and I was right back up to 165-170 (75-77 kg) quite quickly, then back to the slow gain at 5-ish (2 kg) pounds a year. So, by the time I was 40, I was obese, over 200 pounds (90 kg), most in my belly, an “apple” shape. I had a terrible night-time sugar eating habit and would eat “dessert” (after pasta or potatoes or garlic bread) in the form of cakes or cookies or chocolate bars …or toast and jam if that was all that was in the house… from after supper until I went to bed.


In 2006, at 48 years of age, I weighed 226 pounds (103 kg) and rejoined Weight Watchers. I did fairly well, until at 182 pounds (83 kg) I plateaued. Inevitably, my weight started to creep back up, this time 6-7 pounds (2.5-3 kg) a year, until in 2013, now 55 and freshly retired, I was back at 210 plus pounds (95 kg). With all kinds of time on my hands, I attempted weight loss again. This time, I counted calories, eating a maximum of 1200 calories a day, walking, and following a protocol in which I limited calories for two weeks, then I had an “eat up” day where I would eat the amount of calories I would need for maintenance (1800) which basically amounted to a “cheat meal”. I would do that for two weeks, then add an extra “eat up” day so I was “eating up” twice a week for two weeks, then back to once a week. I did this for 12 weeks, and lost a bunch of weight, going down to 168 (76 kg).

I started eating lower carb at that point… I was beginning to understand that real, whole foods resulted in weight loss, however, I still had a huge sweet tooth, and felt that as long as I counted calories and kept moving I could eat everything, including starch and sugar. I maintained 168 (76 kg) for almost a year, but never lost another pound, even though I tried by continuing to cut calories. Frustrated, I stopped trying. I went back to work part-time, went back to eating sugar all night, and by December of 2017, now almost 60 years old, I once again weighed 210 pounds (95 kg), was in excruciating joint pain, to the point I could no longer enjoy walking or any physical activity. Worse, confirmed by blood work, I was pre-diabetic, and ripe for heart disease, with triglyceride levels off the chart.

So I went back to Weight Watchers, and quite quickly lost 10 pounds (4.5 kg). I could not lose another ounce, no matter how many points I counted. I would get frustrated and binge, which resulted in overnight gains of 5 pounds (2 kg) that would take a week to get rid of. I was losing the same 5 pounds (2 kg) over and over! Of course, I blamed myself, my lack of willpower, my laziness, all that negative, nonproductive self-talk, none of which was even true as I was about to find out.

In February of 2018, I stumbled across the Diet Doctor site, I don’t even remember how. I took advantage of the 30-day free membership and went first to the video section. I watched the video “Konvincing Kids Kounting Kalories is Kooky” and suddenly, it all made sense. I joined the LCHF 2-week challenge, and instantly, within the first few days, I saw results. My night-time eating was the first thing to go, effortlessly. I would realize it was bedtime and I hadn’t thought of food since dinner. My joint pain decreased. I started to sleep well. And the weight was falling off me, at the rate of a half pound a day (0.2 kg). I spent hours on the site, utilizing the many resources available, watching videos, educating myself on the science of weight loss.

Fast forward to today. LCHF has ceased to be a “diet” and is now a way of life. Once I became “fat adapted” I started incorporating intermittent fasting, usually 16:8 but I have done 24 hours as well. I only eat when hungry, and often this amounts to only once a day. I have lost 40 pounds (18 kg), but the weight loss has become secondary. My blood-work has improved exponentially. I can walk 7k with no pain. I sleep 7-8 hours a night. My mood is better. My skin is no longer dry. I look (and feel) 20 years younger. I no longer binge, if I eat more than I should, there are never overnight 5 pounds (2 kg) gains.

Is eating LCHF a magic pill? No. LCHF doesn’t ADD anything. It REMOVES the toxins that make you fat and sick! It’s science, pure and simple. This is how we are meant to eat, and when we do so, the body responds immediately, which is all the proof I need.

I still have 12-15 (5.5-7 kg) pounds to go to get to my “goal” weight, and slow but steady its coming off. I’m learning more and more every day about this way of eating and this way of life. And I have a new goal: to shout from the rooftops so that all the people I know, and there are many, who are fat and sick and tired, and in chronic pain and who think at 40 or 50 or 60 years of age that their life is over. I want the whole world to understand that it’s the FOOD they are consuming that makes them feel that way! And I want them to know most of all that everything we eat, even dessert, can be “keto-ized” – LCHF food is delicious! There is nothing I love more than having “non-keto” guests over for dinner. Especially those who are skeptical of the keto lifestyle. They leave full and satisfied, and surprised that they just had lasagne made with sliced deli chicken or keto lemon meringue pie and never even noticed!!!

I’m freshly retired (again) at 60 and I look so forward to the next 20 years…no kids to raise, no job to worry about, and a body that moves and feels better than it did 20 years ago. Thank you Diet Doctor. You saved my life.

    You're so WRONG! I've been eating keto for a year now, feel great, lost weight. Where's the con?! Case after case shows the evidence that not only is this a healthy diet, helps people easily lose weight, but also reversing several diseases! Many studies prove that keto is a healthy diet. Lots of reputable doctors concur and have written books praising the ketogenic diet as well. Cholesterol and fat don't kill us, carbs/sugar does!

    Ignoring the outdated and unhelpful comments made above by Bill, thank you Mary for sharing your story - your before and after photos confirm that eating a healthy, real food and low carb diet is key for improving health and you are an inspiration to others.

    Let's just think about who profits from keto (other than those who eat keto): farmers, ranchers, fisherpeople. This is a diet of eating real food. We were made to function best with real food. Who profits from speaking against keto? Big pharma, processed food manufacturers and sellers, quack diet purveyors.

    I have tachycardia/bradycardia and a multitude of other arrhythmias issues. I had gained to over 200 lbs I was very ill and going fast, I was 58 years old. With me it was the heart made it impossible to move and sugar was my balm. After receiving my pacemaker and meds to control my tacky/Brady issues I was still having arrhythmias, daily, constantly. I was so frustrated and emotional. I got to a point that I was angry at my body, I decided that, I would try to take back some control from my body. I asked my doctor about cutting out sugar and carbs, he said ok, go for it in kinda an offhand way. I couldn't believe what happened. Within 48 hours my arrhythmias had almost completely disappeared. I still have mild flutters but nothing like before. It has been 18 months and I have stopped having to go to ER with runaway heart, I can travel again without fear. I didn't do keto because I didn't know what that was but I don't eat carbs and never sugar. One time, on vacation, I ate something that had sugar in it, I didn't ask enough questions, and had a terrible tachycardia event. Oh, yeah, I lost 50 lbs. For a while I was losing so fast my husband said I would have to wear baggy clothes cause by the time I washed them I was into new size. I went from a tight 18 to a baggy 10. So, Bill, scoff if you want, it saved my life.

    omg Robin...Congratulations!!!
    I have been keto for under two years now and would never go back!! I don't have any health issues and plan on keeping it that way! Who says eating veggies, healthy fats and meats are unhealthy have not done their research [and they usually don't plan on doing any...they just enjoy trolling]. This site is so helpful and beneficial to the lifestyle. I enjoy hearing stories like yours.
    Thank you for sharing!!!

    Wow Robin. Just add some butter in now and lotsa magnesium, vit D etc and you'll feel even greater. And of course wow Mary. I just don't get why these trolls pay money to belong to a site they want to trash.

    Mary, your success story is one of my favorites so far! Your story sounds nearly exactly like my own....including the occasional successes with weight watchers. LCHF is also saving my life! I'm down 40 pounds so far and my blood glucose levels are getting better (I had developed full blown type 2 diabetes many years ago). Hooray for us! I can add to my story by saying that over the years of being treated for diabetes, I have been sent to a multitude of nutritionists and dieticians.....and supposed "diabetes educators".....always to be handed the same "exchange diet" that looks an awful lot like the weight watchers diet form the 1970's. These diets are all based on the myth of the four food groups (with cow's milk being one of the groups). Heavy in carbohydrates and very low fat. I paid them all for their advice...and so did my medical insurance company, while the docs that referred me prescribed any number of patent medicines that left me with a mounting list of side effects and sometimes very scary low blood sugar reactions. I am beyond happy that those days are over!!!! I'm finally headed in the right direction!
    Thanks for sharing your story.....success stories are fun to read.....I feel like I have cheer leaders all over the world!

    Mary, congratulations on your success. Very inspiring and you radiate beauty.

    And I'm another just like you Mary, loved your honesty and your before+after photos. You look amazing!
    Thanks Robin, 2 months ago I was diagnosed with Afib +put on a toxic cocktail of meds with very nasty side effects but now off 2 of them and with LCHF, plan to be Afib +med free before long. Diet doctor saved my life twice so far.....have already kicked T2D as well as a very painful ankle injury for which I was told that I'd need an ankle replacement!! I've been on on LCHF and diet doctor for the past 3 years....and it suits me.
