Yet another study shows no weight loss benefit for low-carb

Another nail in the Keto Koffin, so to speak.

(Seriously I am not anti-keto--I just really, really wanted an excuse to type Keto Koffin)

If you don't want to follow the link--study showed (again) no weight loss difference between high fat/low carb and high(ish) carb/low fat when calorie/protein intake the same.

    While not a low-carber myself, I've read that its theoretically effective for stubborn fat (apparently keeping plasma fatty acids high inhibits alpha-2 receptors on stubborn fat). So, I'd like to see a study comparing the diets in lean people getting leaner. You'd expect better body composition going keto. You wouldn't expect a difference in individuals with a big surplus of fat mass (as in this study).

    I don't understand how this nails shut the keto koffin? If it did anything, it solidifies that LCHF is a sustainable alternative to the LFHC weight loss push. Additionally these subjects were eating > 50 carbs which may mean keto levels were never truly obtained, and this was specific to men.

    There are other studies showing that there is no metabolic advantage to ketogenic low carb diets over non-ketogenic low carb diets: http://www.bodyrecomposition.com/research-review/ketogenic-low-carbohydrate-diets-have-no-metabolic-advantage-over-nonketogenic-low-carbohydrate-diets-research-review.html/

    What do you all think of Dr. Peter Attia's experience? He claims to have gone from 195 to 170 while increasing his calories from about 3200 cals/day (carb heavy) to 4300 cals/day (keto) while keeping exercise constant or even decreasing exercise some (he worked out 3-4 hrs/day and is an endurance athlete)? I have no reason to doubt him.

    See:

    Also see below on effects of his keto diet on his athletic performance:

    No one can say this man doesn't know his science on this subject (he doesn't know all obviously but is well educated on the topic).

    I don't do keto but it does seem to me there is something to it.

    Science does. Physics doesn't work that way.

    Explain your comment, "physics doesn't work that way" please. The CICO model doesn't take into account excretion. If it did, then you can see that no conservation of energy principles are violated. Do you think he was lying or made gross errors in his logging?

    For me, there is something to it. It isn't a huge advantage but it seems to boost my CO a bit. I lose faster at a LCHF diet than a higher carb diet. I went with close to my calculated calories for losing 1.5 lbs per week. It was set at 1420 kcal but I ate an average of 1500kcal. I lost 2-3 lbs per week, excluding the first few weeks when I lost even more. That's over a 1000kcal deficit per day.... I doubt my TDEE is somewhere between 2500 and 3000kcal - keto seems to agree with my body. BUT I am one of those people in keto for the theraputic effects. I tend to lose better when my health improves.

    There's something to it for me. For others, the appetite lowering effects is enough. For those who don't experience the reduced appetite and have no theraputic need of a ketogenic diet, they don't stick with it for long, and why would they? ;)

    Dr Attia- His update in March 2016...

    These days I’m eating about as freely as I have in 7 years. I’m still carb-restricted by the standards of most Americans, but nowhere near the ketogenic lines of 2011, 2012, and 2013. I almost always skip breakfast, and lunch is usually a salad (“in a bowl larger than my head,” if possible). Dinner is usually a serving of meat with more salad and veggies. I’m more liberal on fruit and even occasionally rice or potatoes. Also, in moments of weakness I sometimes lean into my kid’s crappy food.

    Doesn't seem like he stayed Keto. I wonder why?

    I know he has changed his diet. I don't remember him explaining why but it doesn't change what happened to him when he lost his weight. I think he likes carbs probably and might think he is missing out on some micro-nutrients going keto. I don't know. I don't plan on going keto for those reasons unless I need to for a medical condition.
