Interesting video. My physician told me the opposite two years ago:
Physicians are not dietitians, nor are they properly educated on nutrition. Almost any GP practicing as a nutritionist is engaged in some form of malpractice.
Most General Practitioners are Idiots who are too arrogant to recognize where their skills end and other disciplines begin. An honest GP should refer you to a dietitian for serious nutrition advice, or in the very least administer it with a grain of salt; it's as simple as that.

No, ONLY if you eat a diet very low in carbohydrates, and this is an extremely unhealthy diet. It puts the body in a state called
ketosis. Carbohydrates are the preferred, and ideal, form of energy for the body because they are metabolically much easier on the system.

No, he was espousing ignorant propaganda that he has arrogantly accepted as a medical fact, because he is, like most General Practitioners, an idiot.
Fat isn't evil; we need fat (
essential fatty acids, which are unsaturated fats- we do not need saturated fats), and fat can be a decent source of calories making up a small portion of the diet. Carbohydrates are not stored in the body long term, but quickly metabolized (the liver can store them for a few hours); excess is turned into fat and stored in that form (only fat is used as long term energy storage in the body, due to the high energy density).
noelle wrote:Calorie-density is not an indication of 'unhealth.'
Of course not. It is the calorie to nutrition ratio that is more important. Also important is avoiding harmful substances. Density itself is not important. However, a very high calorie density indicates a probable lack of fiber (because fiber is non-caloric and lowers density), and that IS unhealthy. High calorie density also makes it easy to overeat, which is also unhealthy.

What about fat? You seem confused here.
When food is high in fiber, it simply is not physically possible for most people to eat enough to become obese. You literally can not eat enough celery to make yourself fat; you'd probably starve given the energy needed to chew and digest it compared to the calorie content.
Foods with high calorie density make overeating more probable, and in some case it's functionally impossible without them.
Now, if you actually control yourself, that's not a problem, but most people can't or won't do that. So, you have to consider the reality of the situation, and not some ideal world where people are good at math and have self control.

No, they aren't.
Whole nuts and seeds are pretty high in nutrition, extracted oils (which is inherently a kind of processing) have little to no nutrition beyond calories even when they're not filtered.
