What is your blood type? The background for this is that my sports scientist friend has shared many insights about keto over the last 15 years. His research, based on approximately 50 athletic patients/clients, indicates that there appears to be a certain blood type that those who have it thrive on keto right from the start. No keto flu and are super responders with regards to weight loss. Keep in mind that weight loss for these patients was not the primary goal but rather a secondary goal. Those patients of this particular blood type lost on average 2.3 lbs per week and achieved a goal weight in a short period of time. 10-15% of body weight. I will share the blood type once I have some responses. What have been your experiences when starting keto?
I would like to conduct a simple polling question
A- (A negative) and my experience is right in line with those numbers. 60 lbs/27 kg in 5 months, ~2.7 lbs per week, 17-18% of my body weight.
āKeto fluā - none to speak of. I had been a horrendous carb eater, but was also used to eating once per day. Coffee in the morning, a big meal in the evening. I was also scared by a diagnosis of type 2 diabetes, and very soon the feeling of ādoing something good for myselfā and āturning the ship around,ā overwhelmed any misgivings or discomfort.
It was not even āhardā to do it, and it sure made a difference.
O+ here. Donāt recall any keto flu and so far itās working just fine. Be very interested to hear the results.
A+ for me, I did loss weight quickly and donāt remember any keto flu that slowed me down. But I couldnāt stick with the super low carbs. I am doing my best with a moderately low carbs diet of all natural real food, no fast food, no soft drinks. And I have to keep my fat intake and salt intake to a moderate level.
B-. I found keto easy and lost so much weight that I started getting nervous. I ate 4 lbs of trail mix just to make sure that i could still make my weight go up a few pounds if I wanted to.
A+. Keto worked quickly and easily for me, no keto flu. Still eating ketovore 4 years later. Female but Iāve always tended to take off weight and put on muscle without undue difficulty. 35 lb / 25% body weight lost, 20% in the first year. Been at or below my highschool graduation weight for 2.5 years now.
One odd thing Iāve noticed is that although I am very low carb and sometimes zero carb, and that feels right, once in a while I go off plan and itās a good thing. Example, Iāve been sliding into feeling rather worn down and irritable in the last week or two. Went out to lunch yesterday and had a beer. Now obviously that ācheered me upā a bit, but what I notice is that today I am back to a normal mood and more energy. Iām pretty sure I wasnāt suffering from an alcohol deficiency, haha, so Iām crediting the carbs or maybe the B vitamins in the beer for rebalancing me. I could probably chalk this up to other things, but itās been a consistent pattern. I donāt need that boost often, more than once in a fortnight and Iāve got the carbohydrate blues, but the occasional ear of corn, sweet potato, beer, perhaps an overage of nuts seems to be of value.
Blood type: A+
Weight loss: 80 lbs./36.4 kg over 6 months (3.3 lbs./wk.)
Percentage: 26.3% of starting weight
Keto āfluā: none, because I heeded Phinneyās advice to keep my salt intake up (and it stopped my migraines, too)
Phinney and Volek say their data show that the usual loss among their research subjects is around 20 % of starting weight, so I consider myself lucky, even though I could stand to lose another 80 lbs./36 kg. Iāve never heard Phinney talk about blood type, however.
I never exercised during the period of fat loss, either, except for the normal effort involved in cleaning out my motherās apartment after her death and getting ready for the movers to take me from New York to Connecticut, and most of the fat loss seemed to occur after that, anyway. I really loved not needing to count calories and never needing to go hungry, which is what prevented me from succeeding at previous attempts to lose weight.
A+, not lost much but only minor keto fluā¦I am a woman of a certain age though & not been able to do much exerciseā¦
O+ Been Keto since April '15. Lost about 65, gained back about 10, and bounce around in that range. I would not consider it easy loss - it took a few years. Like many or most here, Iāve been fighting that ābattle of the bulgeā for a long time and I think thatās probably the biggest issue people have.
B- I found keto easy to adapt to with no āKeto Fluā. Fat loss worked a treat. Most of my targets were achieved in 3 months.
20kg lost and diabetes reversed,
AB+ here. Donāt think I ever had the keto flu, the multiple times I started Atkins and then transitioned for good to Atkins. Lost weight (went from 43 inch pants to 34 inch pants) but gained weight after shoulder surgery and trying a very high saturated fat diet. Lost the most weight initially, slowly losing weight now. Will be 11 years of keto on 1/1/25.
Not that close to what I was when I was 17-20, but I was also much more muscular back then.
I am A-, I got the Keto flu when I started. I have been KETO 2018. Germaine
O+ here. I had terrible keto flu when I started and have had trouble balancing my ketones the entire time Iāve been very low carb. Recently, I upped my carbs. Iām probably around 50-74 most days, sometimes a little more, sometimes a little less. I am feeling much better, sleep is better, heart palpitations are much improved. My body is feeling less stressed overall.
AB+ here. The only problem I had with Keto was the worst constipation
in my life. In 3 months, I went from 192 lbs to 160 lbs. This was too much.
I was feeling weak and dizzy, so I backed off to 170 lbs and feel much
better.
I started keto because I was pre-diabetic and wanted to discover
the supposed brain advantages of keto. Iām out of the prediabetic
range, but, so far, I havenāt noticed brain changes.
claimed advantages. My energy level is still low.
Welcome!
Can you tell us more about what ābrain advantagesā you hoped for?
And Iām assuming your constipation issue resolvedā¦?
Also to help us understand and perhaps make suggestionsā¦
how long have you been eating keto, what is a normal dayās menu look like, do you know how many carbs and calories?
Glad youāre here. Look forward to your input.
O-
I donāt recall any keto flu, but I started out low carb ala Atkins before a friend turned me onto keto and this forum. Weight came off fairly easy and steady.
B+ here, no keto flu and only takes me about two days to adapt to it. Did do it for health reasons and weight loss. Have lost 18% of my body weight in 16 weeks (if my calculations are correct, my brain is a bit fried 
). Gone from 86kg to 70kg. But if I remember correctly B+ is not the blood group you are referring too.
A negative but I donāt want to share my experiences until I hear your more about this study.
