Nutritional nuggets to combat conventional dietary guidelines
Dr Zoe Harcombe
Thermodynamics
-what the laws actually say; how they have been
misapplied to weight loss; the thermic effect of macro nutrients (the work of
Jequier 2002, Feinan and Fine2005) and the isocaloric advantage this gives.
•The origin of the calorie formula; the fact that 1lb does not equal 3,500 calories and what it could equal instead (work of Rubner 1901, Bozenraad 1911, Wishnofsky
1958) and what impact this could have on
weight loss theory and practice.
•The historical evidence for what happens when we try to create a calorie deficit -from Benedict 1917, through Keys 1945,Stunkard 1959 to Franz 2007 (26,000
people reviewed in 80 different calorie deficit studies).
•The misunderstanding of what saturated fat actually is: the basics of nutrition/macro nutrients/fat composition of foods. The European correlations for saturated fat intake
and CVD. Including theBMJ open paper on saturated fat.
•The correlations for average country cholesterol levels and CVD in all World Health Organisation countries for men/women/CVD deaths and all deaths.
•Micro nutrients comparisons for sample foods to test the hypothesis that "whole grains are healthy"

My nan had a small farm, and this was how she saw 'healthy whole grains' - she called them 'animal feed' and didn't eat them much. She loved meat and plants like cabbages though.

I've been dieting all my adult life starting at age 14. Each time I did well on calorie restriction lost weight, but got tired, hungry and obsessed with food with all that planning calories. Each time I put the weight back on with a new higher normal. Nearly every year battling my increasing weight and following all the BS low fat, wholewheat, PUFA margerine, vegetable oils. By the time I was 60 I was prediabetic, heart condition, fatty liver, and on seven medications weighing 255lbs. In January I read books about KETO and FASTING. (Fung, Lustig, Taubes, Teicholz, Perlmutter). Now I am 210lbs, have dropped 4 mediations, no longer have heart pain. My A1C is normalised, HDL up , Triglycerides down. Feeling great. No more bloating, no more wind, no more fatty liver. Stopping eating carbs means not being hungry. It means being about to deal with your appetite. Now I eat steak and butter, fish, dairy and lots of real low carb vegetables. I feel great. How did I ever eat those disgusting margarines and Veg oils. If they taste like shite then they are shite.

The calorie deficit worked for me, but not in any predictable way. When I lowered my caloric intake, my weight didn't budge. When I lowered the number of meals to 1 or 1.5 per day, all with the same caloric intake, my weight started to drop. And when I cut most carbs, my weight dropped even faster! And the last 10 lbs I lost by adding more fat and totally getting rid of carbs!

Long story short, arthritis pain 75% relieved, down about 20 lbs (5'10" 160lbs now), appetite control for the first time in my life and really, really, really enjoying my food. Low carb and going back and forth with high fat and higher levels of protein to experiment on my arthritis inflammation levels and for enjoyment.

Its simple : Avoid sugar and processed food and Seed oils. dont be afraid of fat. You can eat carbs, but the amount and quality matters. choose them wisely. eat protein without regret. You can do any diet following this principles and you will lose weight, just dial up and down the amount and presto. In my case I have the most success with keto/carnivore diet, staying below 20 g. If you want to increase the amount of carbs and it works for you fine.

Dug companies are the entities that harvest billions from unwell people. While lifesaving drugs have been developed, they are now making more profit from things like statins, which are useless at best, and often harmful. For-profit medical insurance companies, for-profit health care centers, even not-for-profit hospitals... physicians have to answer to these. If they do not follow 'standard of care' they risk losing their jobs, or being sued.

16:26 - "A tablespoon of olive oil has more saturated fat than a hundred gram pork chop." Olive oil was reportedly originally used for lamps and also on the skin before it was considered a food. People preferred to eat and cook with animal fats - beef tallow, pork lard, and lamb suet. These days, much of the olive oil is contaminated with seed 'vegetable') oils. Or, it is cheap seed oils treated with chemicals to make it seem like it is olive oil. Apparently the Mafia has found counterfeiting olive oil to be more profitable and less risky than selling drugs. (Maybe because Big Pharma got in the game of pushing opiates in the U.S.A.?) Olive oil from Australia and the U.S.A. is most likely the real thing. Sadly, many olive groves in California were turned into housing developments. Not all the trees were cut down, but over time, most homeowners cut down 'those messy trees'. People had no idea how to either press the fruit for oil, or cure them for eating.

I always assumed ( dangerous I know!) that there had been some chemical experiment to determine how many grams of water could be raised in temperature by one degree (Celsius) by burning the substance ( in this case "fat") in something called a bomb calorimeter - this would provide a technical definition of the amount of calories in any substance - since a calorie is a measure of heat energy. Of course, the human body is not a bomb calorimeter, so the way in converts substances into energy (or stores and transforms those substances) is not by simple combustion ( burning calories is just a metaphor !). So while one pound of fat may have the heating power of 3500 calories this does not mean creating a calorie deficit of 3500 calories will cause you to lose one pound of body fat - as anyone who has ever been on a calorie restricting diet can tell you.

Allan Cowley Yeah, if you want to lose fat you should eat mostly fat. The insulin spikes from sugar and starches block the burning of fat for energy.

@@Jefferdaughter no .......Zoe often talks at speed if you care to watch some of her other videos. A sensible person tailors their discourse to fit the available allotted time at a measured pace. There is little point in speeding through a presentation of a complex subject at breakneck speed if some of your audience are unable to follow or take in the information conveyed.remember this presentation was primarily to an audience not KZfaq. Talking quickly without any pauses in a presentation is a common fault of those who are very familiar with their subject and wish to cram as much important information as possible into the time frame but its actually far more effective to talk at a more reasonable speed and say a little less so that more information is taken in and digested .

You are applying mathematical precision over a heuristic, and you have yet to acknowledge the impact of the patient’s starting adiposity and basal metabolic rate. Your absurd but mathematically correct conclusions of weighing 6 lbs in one year is based on ignoring these factors which every dietician knows to include. It is irresponsable to make vague statements about calories not mattering in a society where hyper palatable food is cheap and everywhere. Regardless of the numbers, for an overweight person to lose weight and keep it off they need to learn to control their caloric intake. Of course its a moving target - this is again a heuristic, not a linear formula. Controlling caloric intake doesn’t mean always eating at a deficit, always eating the same amount, always eating less and less, or anything else. It means understanding ones own appetite and remaining in control on average over time. The obesity problem is obviously caused by the continual over-availability of hyper-palatable food to a species best suited to intermittent scarcity.
