Do you have to count calories to lose weight?

Do you have to count calories to lose weight? No, it does not appear to be necessary. But WHY is the answer no, and WHY do many scientists and people in the media still not fully agree?

There’s nobody better on the planet to explain this simply than Dr. Jason Fung. He’s a phenomenon.

  1. Are all calories the same?
  2. Weight control – calories or insulin
    Q&A with Gary Taubes

    A calorie is not a calorie, and even worse, the insulin response to carbs is not the same to everyone. Metabolically healthy people not only have a better glycemic response (their bloodsugar does not spike as much) to slow-releasing high carbohydrate foods, such as beans and lentils, than diabetics and the insuline resistant, but also the glucose response in diabetics and insulin resistant is much higher and lasts much longer. Which means that not only does it make a difference wether you give someone 100 calories of olive oil or 100 calories of sugar, but also if the person you give 100 calories of sugar to is diabetic, insulin resistant or metabolically healthy.
    This is so important, because there are still many (metabolically healthy and therefore thin) people who still labor under the delusion that if fat people would eat and do the same things they do, the fat people would become as skinny as them. (I've got friends like that, whom I love but who also can drive me up the wall with their obtuseness... "of course you can eat potatoes! Everything in moderation... look at me! I eat everything, just in moderation (implying that fat people 'overeat', ie: are uncouth, guzling pigs who can't control their eating) and I'm slim.. You can be too, just... be moderate!" Argh!!)

    there's a great little lecture by prof. Grant Schofield about this (watch around 15 minutes in for some very interesting graphs)

    Ok so the metabolic rates may shift more in your favor if you eat specific foods. But it still will require a caloric deficit. Just because you increase your BMR by 200 calories per day does not mean you can eat above your TDEE with certain foods.

    Matt what part of it’s not calories that matters do you not understand. Protein stimulates hormones to build muscle. Fat stimulates hormones for satiation revitalizes cells and does a million other awesome functions, and carbs we are meant to eat contain most fiber and nutrients however the processed carbs we eat today are empty and spike insulin causing problems. Fat people are fat bc of processed foods NOT CALORIES. Ive lost 125lbs I bet you’ve never lost more than 10 lbs I doubt you even know much about the human body. Just regurgitating myths
