By the same token if we have g of glycogen to deplete and it should take 5 days. Why on a psmf do we need so much protein at the start when our glycogen level is high. Because developing ketosis has nothing to do with muscle glycogen. It has to do with liver glycogen status and a couple of other things and the liver only holds about 50 grams and will be at least partially depleted after an overnight fast and mostly depleted by about day 2.
I will have to disagree with that. Carbohydrates join the structure of the cell membranes, and they are used in the production of enzymes, neurotransmitters, and they make up part of nucleotides and hormones, showing structural function in the human body. The body can produce glucose from other substrates lactate, pyruvate, alanine, leucine. Hence carbohydrates are not essential to come from the diet. This article is full of misconceptions about carbohydrates.
First off all, even the oxidation of fats burns off the flame of glycolysis. Most importantly, however, is the energy requirement of your brain. Your brain requires approximately kcal per day of carbohydrate fuel. Thank you for repeating many old ideas that are incorrect.
The brain shifts to ketones a fat derived fuel and can run just fine in some people others feel terrible. And you dont need carbs to burn fat. I came to the conclusion that I am not insulin sensitive. And that I need to eliminate a lot of carbs, to minimize the fat gains in a bulk phase. Hi — I really enjoyed reading this article. I also exercise regularly vigorously with both cardio and resistance exercises 6 days per week, at least one hour each day. Which of your books would you suggest; Rapid Fat loss or UD2.
Hello, The article and the feedback was great….. I have a question about what type nutriton my sister need based on her schedule below? Eat at least 3 hours before bed time. Average Daily Schedule: Up at 4 am; 50 minutes drive to work; work at 6 pm, busiest time at work 8 am — 1 pm; Work end 6 pm, 50 minutes drive home; Home at 7pm, sometimes cook dinner after 7 pm.
Sincerely, Anthony. I feel like you can eat whatever you want, you just have to outhustle your carb intake. Use more glycogen than you put in. If you want pizza, cookies, cakes, chips, donuts, cereal,and all other sweets and goodies….. Lyle, thanks for the article. Atkins famously excludes them from all carb numbers; are your numbers, rough as they are, intended to be used the same way?
Hi Lyle, brilliant articles, same question as Evan, should we be excluding indigestible carbs as in atkins when calculating carb numbers? Thanks Danny. In your example of 2 worksets requiring 5g of carbs for replenishment, how many carbs do you suppose are needed for heavy low rep sets? Say, reps to failure of squats. I assume there would be a significant variation between squats and bicep curls.
Maybe start with Comparing the Diets series for starters. Because nobody is saying one size fits all. Thank you. I found the table especially beneficial to me. I know that carbohydrates should primarily come from fruit and vegetable sources. My question is, if I am to consume g carbohydrates in a day, could some of this number be made up from sweet potatoes.
Or should it come solely from low carbohydrate vegetables and fruit advocated on the Paleo diet. Looking at carbohydrates alone assuming calories were set at maintenance , would a carb intake of around that gram mark assuming no exercise prevent this slow down? Or would you recommend a higher carbohydrate intake to keep the metabolism functioning optimally? I just wanted to say a few things, I have yet to read other articles, which I will once I have ample sleep. I realize this topic is contraversial and many topics have changed over the years with how our body works.
Secondly, there are many studies on acidosis and weight loss. I believe this is what a lot of the medical field has a hard time swallowing. It also scares me to think that people are taking bicarbonates to counteract this acidosis. There are many studies to support negative affects of long term use of bicarbonates, and I know very well that bicarbonate just like the kidneys excrete is only short term solotion for an initial problem that needs to be fixed. Long term acidosis damages all your body organs.
On a side note, it is why soda pop is so terrible even aside from the tremendous amounts of added sugar. We do know that having acidosis in our blood makes it more difficult for our body to function in general, and of course we need our body to function to live if its not obvious to all and of course to lose weight on a cellular level.
It also scares me that you use the words starvation when you type about ketosis, because of course, its what it is. And personally, I agree with a few previous points but are still willing to listen by reading journals, not anecdotal books, no offense.
I think by being in ketosis for short term may be beneficial, but logically, I cannot accept starving my body and disrupting its processes. Its not all about burning sugar, there are a million other processes that run the show, and many we do not know of yet. Everything we put in our mouth is at a risk— even your own foot.
PS: do you have any information on medium chained fatty acids? How long will it take me to get into Ketosis?? I do about 45 min of weights and I take on some intense, very aerobic hikes.
I currently weigh kg and I have visible abs but a little soft towards the bottom of my abs i. I currently train with weights times per week and do 45mins of intense cardio per week soccer.
With regards to carbs, I currently have a cup of oats for breakfast and a piece of fruit, a small amount of canned beans grams approx for lunch, 1 Ryvita biscuit in the afternoon, an apple in the afternoon and a small sized potato for dinner. My question is, how much can I reduce the carbs I currently consume as per above diet , without losing muscle mass? How can I change my diet to get lean as possible whilst maintaining muscle mass?
From my own experience g carbohydrates a day is to much to enter ketosis. Hey, great article and thanks for such a thorough description, I wondered if anyone could give me some advice on my own situation.
I weigh about lbs, walk briskly about 1 mile per day for exercise which somewhat limited due to arthritic knees. Please advise. Lyle, will you marry me? You cover it all with such distinction and for everyone. I love all your articles and have most of your booklets. But in all honesty the author is correct and not false as you have stated.
The theory is that fat is a more stable fuel for the brain, with less ups and downs. My father who has the same condotion, was prescribed powerful stimulants, including meds that containh GHB.
Love your information on carb requirements, but can you help me? I am 53 and a competitive cyclist. I only ride 2x a week due to work. But I ride miles of hard intervals and muscle fatiguing pushes during those two rides. I have felt weak lately while I have trying to loose weight to to obtain a competitive edge. When and how many carbs should I be consuming?
What about protein requirements and how much? I am going to re start p90x original one not 2 am nursing and have just started dabbling in the low carb thing. Not from sugars or starches, I get some when I drink my whey protein which I mix with light soy milk. I also include some sort of veggie, occasionally some berries or fruit.
What do you recommend for my carbs? Excellent summary. I end up running out to the , getting a family-size bag of potato chips and a 1-liter bottle of Coke, and finish both off before going to bed. Bad, very bad. I basically used his principle of 15 sugar grams per day and about ish carb grams per day along with spin class about times a week and doubles tennis times a week.
Now 4 years later and married for the last 2 years and in full blown menopause I have gained about 15 lbs back. I must confess over the last 2 years I have been eating too much and doing less exercise.
I can not seem to lose these pounds or inches. I also must confess to cheating over the weekends with some high sugar foods but mostly am doing the same things I was doing 4 years ago. Do you think with the menopause I need to cut back even further on the carbs? To work out your ideal carb intake, bodybuilder and nutritionist Dr. Layne Norton recommends first calculating your calorie needs. If you're what's known as a mesomorph and are naturally muscular, multiply your body weight in pounds by Ectomorphs, who are naturally skinny and have a hard time gaining muscle should multiply by 16 to 17 and endomorphs, who naturally carry excess fat should multiply by 13 to This is the number of calories you should eat each day.
Your protein intake should be between 1. The rest of your calories should come from carbs. Low-carb diets can be very effective for losing fat quickly in a short space of time, claims Norton, but they lead to muscle loss, as carbs help to preserve muscle.
Very low-carb, or ketogenic, diets are not optimal for building muscle either, writes sports nutritionist Lyle McDonald in "The Ketogenic Diet.
