Why low carb?

crushcrashcrush 8y ago
Carbs = Sugar. Period, end of story. The key to good body composition is a high protein, low carb (low sugar) diet. Avoid foods that spike insulin. Anything else is hogwash, because calories are not calories.

  How do you get fibre then?
  - JoelMcCracken 8y ago
    a large number of vegetables are low carb.
    - ip26 8y ago
      By weight maybe, but by relative composition, 80% of the calories in broccoli come from carbs.
    - uhtred 8y ago
      What about fruit?
      - crushcrashcrush 8y ago
        Largely fruit has too much sugar. Berries are okay (blue and black and red)

        What! I surrender. Are people really not eating fruit because of the carbs? Oh my. It's fruit! One of the healthiest snacks you can have!
- crushcrashcrush 8y ago
  And before I get someone saying "just run at an 'energy deficit' - consume less calories than you burn" - I say, if you want to look and FEEL good, the person who eats 1,500 calories a day of carbohydrates vs 1,500 calories a day of protein, vegetables (carbohydrates largely bound by fiber), etc - will look and feel vastly different. This is why it's not just as simple as calories in - calories out.

    Most people seriously interested in this topic should already be familiar with the "insulin index" paper (was reposted to HN within the last couple weeks). EDIT: Or maybe just 3 days ago? Seems like longer. https://news.ycombinator.com/item?id=19369743 https://news.ycombinator.com/item?id=19369743

  A high protein diet can also spike insulin, it is more important to eat healthy fats.

  Some amino acids are potent insulin secretogogues; proteins induce a fairly robust insulin response.

  "because calories are not calories" What are/were they then?

Because metabolic insulinemia is out of control these days and I find the keto people's studies quite convincing (look into Ivor Cummins' presentations on YouTube), in addition to hearing similar points of view even in some anti-keto diets. It seems pretty likely to me that sugar is very easy for us to over-consume in modern lifestyles. Less convincing to me is the full-on keto diet itself. It's great that it exists as it started an excellent conversation on diet, but I rule it out because most cultures' dietary staples have been starchy carbs. The problem imho is: - It's too easy to overconsume carbs in modern lifestyles, and some of the carbs we consume spike our insulin too much (certain GMO crops in particular). - It's too easy to consume non-whole-food carbs. Whole foods come with things that reduce the metabolic burden of eating them (fiber, antinutrients like phytates, antioxidants). - The people who subsisted on carb-based staple foods led significantly more active lifestyles in the past than most people today, and did not have the abundance of food that we do now.
