It's not just "harder", it requires skills and knowledge, which most people don't actually have.
The point is that "exercise" isn't helpful advice to lose weight. First, it's not terribly effective at it over short durations, and people need to know that what they're doing is working. Second, if somebody isn't already exercising, they're going to hurt themselves, have a six week recovery time, try again, hurt themselves, and give up on losing weight. Third, you're communicating something different than what you think you are; "Go for a walk every day" is good advice, by comparison to "exercise". The temptation is to object that that is exactly exercising - but it isn't what people think when you tell them to exercise.
I've been both. My natural tendency, absent constant pressure, is to settle 40-50 pounds over my ideal weight - and it's relatively easy for me to lose weight now, but mostly because I know it's possible. The first time I lost weight, willpower had nothing to do with it - I had a minimum-wage job that kept me constantly active, and I didn't feel like I could afford to waste money on anything but the minimum sustenance of food. So I was dieting and exercising against my preferences. Since then, I've been able to lose weight - because I knew it was possible. Without the prior experience of having lost weight, it feels like an impossible achievement.
I don't recommend having this argument. It's useless in almost every respect.
There are two fundamental issues. First, most people don't understand what a Calorie looks like, and think the difference between a healthy weight and an unhealthy weight is a large amount of food, rather than a small amount of food compounded over long periods of time. Want to lose weight in a sustained and sustainable fashion? Subtract a small amount of food over a long period of time. Instead, people crash-diet, then go back to normal eating habits.
An extra apple a day translates, over years, to up to 50 extra pounds. Looking at two people's daily diets, one is overweight, one is healthy, and most people couldn't tell the difference by looking at what they ate.
The second problem is that exercise is incredibly unpleasant if you're overweight. If you're currently in shape, try tossing 50 lbs of weights into a backpack the next time you exercise. Or better yet, don't, because you could hurt yourself pretty easily in exactly the ways overweight people injure themselves when doing things like jogging.
It takes physiological issues to gain serious amounts of weight in the first place; these won't stop you from losing weight, but they'll make it harder to maintain a steady weight. Normal people fidget or otherwise increase their base level of activity when they overeat, burning off excess calories. Overweight people have to be more deliberate and conscious of these things.
You think that an argument that ultimately boils down to "Look how capitalism is a failure at providing basic things" isn't going to provoke defensive reactions?
This doesn't even pretend very hard.
That does not mean never ever having a single negative emotion, just as I presume that he was not speaking of never having any emotions of any kind.
I was, indeed, speaking of not having any emotions of any kind. Or rather, not qualitatively experiencing them; I'd get angry, for example, but I'd notice I was angry because my hands would start clenching of their own accord, not because I'd experience anything resembling an "anger" qualia, or have my thoughts actually influenced by my emotions. To such an extent that, because I didn't experience either lust or love or any of the variations on those two themes as an internal emotive force, I assumed for many years I was asexual.
Absolutely agreed. But it's about conflicts among preferred outcomes of a decision, not about preferences among disconnected world-states.
Less about two outcomes your preferences conflict on, and more about, say, your preferences and mine.
Insofar as your internal preferences conflict, I'm not certain ethics are the correct approach to resolve the issue.
If they're unaware because there's no reasonable way for them to be aware, it's hard for me to hold them to blame for not acting on that. Ought implies can. If they're unaware because they've made choices to avoid the truth, then they're ethically inferior to the version of themselves which do learn and act.
This leads to a curious metaethics problem; I can construct a society of more ethically perfect people just by construction it so that other people's suffering is an unknown unknown. Granted, that probably makes me something of an ethical monster, but given that I'm making ethically superior people, is it worth the ethical cost to me?
Once you start treating ethics like utility - that is, a comparable, in some sense ordinal, value - you produce meta-ethical issues identical to the ethical issues with utilitarianism.
Ethics is solely and simply about decisions - which future state, conditional on current choice, is preferable.
From my perspective, we have a word for that, and it isn't ethics. It's preference. Ethics are the rules governing how preference conflicts are mediated.
I'm not trying to compare a current world with poverty against a counterfactual current world without - that's completely irrelevant and unhelpful.
Then imagine somebody living an upper-class life who is unaware of suffering. Are they ethically inferior because they haven't made decisions to alleviate pain they don't know about? Does informing them of the pain change their ethical status - does it make them ethically worse-off?
Well, I followed a policy of strict emotional regulation, and it made me anhedonic for more than a decade. I'm actively working on feeling things, whereas previously, I would have described my emotional state almost entirely in terms of equanimity, although, since I didn't know the word, I used an artful description of same. (In an emotional state, I would describe myself as balancing on top of a very narrow tower, where emotions were winds attempting to knock me down.)
Which is to say - in my experience, you don't get to pick and choose which emotions you experience. If you start refusing some, you'll discover they all fade away. This is initially extremely attractive, if you're experiencing intense negative emotions, but in the long-term, I believe the term for the mental state this produces is "clinical depression".
It's better to learn to cope with your emotions than to attempt to refuse them.
There are two problems.
In the first scenario, in which ethics is an obligation (i/e, your ethical standing decreases for not fulfilling ethical obligations), you're ethically a worse person in a world with poverty, because there are ethical obligations you cannot meet. The idea of ethical standing being independent of your personal activities is, to me, contrary to the nature of ethics.
In the second scenario, in which ethics are additive (you're not a worse person for not doing good, but instead, the good you do adds to some sort of ethical "score"), your ethical standing is limited by how horrible the world you are in is - that is, the most ethical people can only exist in worlds in which suffering is sufficiently frequent that they can constantly act to avert it. The idea of ethical standing being dependent upon other people's suffering is also, to me, contrary to the nature of ethics.
It's not a matter of which world you'd prefer to live in, it's a matter of how the world you live in changes your ethical standing.
ETA: Although the "additive" model of ethics, come to think of it, solves the theodicy problem. Why is there evil? Because otherwise people couldn't be good.
The information I have seen suggests a pound of fat requires 2-3 kilocalories per day to maintain itself, which implies a range of 30-47.5 pounds from a 95 kilocalorie deviation, which would be 13-20 kilograms.
I have no idea how accurate that is, but it doesn't matter too much, as the underlying point remains the same: People's expectations of food consumption necessary to be overweight are entirely inaccurate. Fat people think thin people must be eating almost nothing at all, thin people think fat people must be eating three hamburgers per meal, where the actual difference is quite small, relative to our out-of-whack expectations.
