    Default Fasting

    Any one currently Intermittent fasting? I am trying to get my **** together diet wise. I have tried fasting and feel great while doing it. I love the idea of Keto, But hate the idea of having to say goodbye to carbs life long. Just wanting to know others thoughts and or experiences with fasting.

    At the end of the day, what dictates weight gain or loss is total calories consumed. Where they come from or when you consume them doesn’t make any difference. Thus, approaches like keto or IF might be useful tools to help control your calorie intake, but neither of them is magic. Neither offers some advantage over any other calorie restricted approach.
    Donít chase the 1%, there is no magic training routine or diet thatís going to provide any measurable results over the basic principles for getting huge and strong: Train heavy, eat and sleep more.

    Fasting initiates lipolysis, which is the breakdown of free fatty acids so they can be oxidized for fuel.
    The type and time definitely makes a difference, as any diabetic knows.
    100 calories from sugar signals your body to store it as fat because sugar causes insulin to rise. 100 calories from lettuce doesn't raise insulin nor fat storage.

    If you cant give up carbs, then practice IIF. The 12-16hrs of lypolysis will more than make up for your carb consumption.

    This simply isn’t true. Lipolysis occurs all the time irrespective of the presence of insulin, which is why the carb-insulin model for fat loss has been thoroughly disproven. Further, lipolysis isn’t even the rate-limiting factor for fat loss- beta oxidation is.

    There is no debate that insulin blunts hormone sensitive lipase (HSL). Maybe you are thinking of something else?

    But irrespective of the presence of insulin, fatty acid oxidation is dependent on total calorie consumption, not carb consumption or insulin response. It is possible to lose fat eating almost entirely high sugar or high carb foods. This is not even debatable. Using your example, if you eat 100 kcals over your metabolic maintenance, you’re going to store fat, whether those calories come from sugar or lettuce.

    Edit to add, to address the previous post directly, HSL doesn’t regulate fat loss or gain. Yes, insulin suppresses the activity of HSL, but so does fat (as demonstrated here: https://www.ncbi.nlm.nih.gov/m/pubmed/9950782/). Thus, you can’t lose fat even when carb intake is low, if you are overeating on calories. If you ate no carbohydrate but 5,000 calories of fat, you would still be unable to lose fat even though insulin would not be elevated. This would be because the high fat intake would suppress HSL. This also means that, if you're on a low carbohydrate diet, you still need to eat less calories than you expend to lose weight.

    The study you referenced shows what happens with most overweight people: all metabolic systems operate subpar. This is not news.
    Your other comment on beta oxidization is not accurate: in order for beta oxidation to occur HSL must occur first. The hydrolysis of triglycerides breaks (or cleaves) the bonds so that energy can be released. That energy is then oxidized via low intensity movement.
    My original comment to the OP was to give him a remedy to an all to common question as to why fat loss stalls and how to get the body to release fat stored in adipose tissue beyond his "set point."
    You claim that science has been totally debunked, based on observation of one investigator as opposed to established and proven application of that science.
    The clients I see that all tell the same story of how their weight loss stalls and all of them (with the exception of ones with medical issues) restart fat loss following these simple procedures.

    Not one study, one of many. I’d encourage you to visit the works of Dr. Layne Norton or Alan Aragon, who have thoroughly dismissed this notion. Or- apply simple logic: how do people lose massive amounts of weight eating things like potatoes or Twinkies if insulin prevents fat loss?


    From the JAMA with several peer-reviewed references attached: https://www.stephanguyenet.com/why-t...-jama-article/


    “Conclusion: Although it is certainly possible to collect observations that seem to support the CIM, the CIM does not provide a good fit for the totality of the evidence. It is hard to reconcile with basic observations, has failed several key hypothesis tests, and currently does not integrate existing knowledge of the neuroendocrine regulation of body fatness.“
