The Benefits And Drawbacks Of The Keto Diet

What is the Keto Diet? A keto diet (ketogenic) is a very high-fat diet, moderate to low protein and very low in carbohydrate, which causes a shift in primary metabolic fuel source from carbohydrates to fats. It also alters fat metabolism so the body produces compounds known as ketone bodies in the liver. These compounds include acetone, aceto-acetate & beta-hydroxy-buterate. These ketones can be used as energy in tissue like skeletal muscle and more importantly, brain. If you’re looking for a more flexible approach then start with the macro calculator to begin losing fat. Under normal conditions, the brain exclusively uses glucose for energy, but in a ketogenic state, the brain will shift to using ketones as a fuel source in order to spare blood glucose for essential tasks such as red blood cell metabolism (red blood cells can only use glucose as fuel since they lack mitochondria). Keep in mind that even with zero carbohydrate intake, the liver can produce about 120g of glucose per day in a process called gluconeogenesis (GNG) for essential tasks from substrates like amino acids and other gluconeogenic metabolites.

    I am on day 1, I counted my carbs for breakfast and thought great, I've had 6 carbs - perfect for stage 1 of atkins... but, just for fun I counted the calories... I totaled at 750 calories.
    I think it'll be hard to stick under 2500 calories during the first week whilst I reach ketosis at this weight, is this to be expected? I'm a lump of a guy, 350lbs/6"4 and ex-powerlifter and rugby player, so I've always eaten alot... but now I'm genuinely worried with the fat contents and calories, even if I do stay under a carb limit?
    Any advice welcome!

    I know that 750 calories sounds like a lot for breakfast, but if there was enough fat in there, you might find that it'll hold you over until dinner. See how things work out for you.

    You are just starting and while you should be mindful of calories, don't let them be the end-all be-all of your diet. You should be most mindful of your body's hunger, unless that hunger is telling you to devour AN ENTIRE BOX OF KRISPY KREME DOUGHNUTS! Then your body is just lying to you. If you eat 3000-4000 calories this first couple of weeks, no worries. You're a very big guy. Just pick your macros and stick to them.
    I love using my fitness pal with a keto hack to help me plan meals and snacks. Days when I EAT ALL THE FOOD are no longer stressors for me. It's okay. It's also okay, if you have days where you just don't want to eat anything.
    My biggest challenge, after accepting that fat in my diet is actually a good thing, is learning to hear and respect my hunger cues again. I have a hard time not eating just because everyone else is or "it's time to eat."
    I love keto because it gives me 1 thing to worry about: macros.
