I don't know how "weird" these tips are.

Cut out calorie dense foods. Oil, fat, etc. A pound of spinach has as many calories as a tablespoon of oil.

Stop using ingredients which add calories but don't add to the meal. For example, when cooking don't use cooking spray. Rely on the non-stick coating. If its an older pan, half second spray of cooking oil is enough to keep food from sticking.

Cold thermogenesis is about as close to an actual weight loss trick you can get because it requires no exercise whatsoever.

Put simply, it's when you're exposed to the cold and your body ramps up its metabolism to produce more heat to maintain your core temperature. This effect is pretty substantial, and it can even compete with moderate exercise even though it requires no exercise at all.

You can prove this by getting into a bath of cold water, taking the temperature of the water before and after your bath, and doing some basic math.

Remember that a calorie (kCal) is the amount of energy it takes to heat 1 Liter of water 1 degree Celsius. So if you've got a bath tub filled with 130 Liters and your body heated it up 2 degrees, then you've transferred 260 calories to the water.

2 x 130 = 260 kCal

Indeed, this is a direct measurement of calories burned because ultimately all energy eventually becomes heat. Although it's an imperfect measurement (it can be somewhat corrected), anyone can do it to demonstrate that there is something about the cold that burns a significant amount of calories. If you were to repeat the experiment with water that is exactly at human body temperature, the result would be very different, much closer to zero.

I actually built a calculator for this purpose because I got obsessed with the effect of cold thermogenesis and have done experiments around it:

^^ Yeah, it's an ugly site, but I mostly made it for myself and I like minimalism. (and dang it, apparently I messed up some of the styling on Safari)

I do believe it's possible to lose a significant amount of weight by combining cold thermogenesis with a proper diet, but I think it's more practical as an adjunct to weight loss. Sitting in cold water isn't exactly fun or comfortable to a lot of people, but you do gain a tolerance to it. Usually I'll plunge into some 15.5C (60F) water and watch some YouTube or whatever. :D

The beauty of it too is that if you manage to shiver after you are done with the bath then that means you are still burning even more calories, and shivering alone helps increase the amount of brown fat on your body, which is capable of burning even more calories.

Lift weights two or three times per week, and walk just barely enough to avoid being completely sedentary. Nothing crazy, I'm talking about using the weight machines at a gym, and walking just ~8k steps per day with a pedometer watch to gamify it. I'm a naturally obese person, and I've read a thousand of these threads over the years. Nearly every comment is either: * Telling you to "hack your body", with keto or what…

1. Exercise helps you eat well. This is so goddamn true, there is a magical threshold of enough exercise where you suddenly just start craving healthier food and lose interest in junk. I have been across this threshold multiple times in my adult life and it’s always really fascinating.

I think this threshold is as much to do with mood as it is body requirements.

Regular exercise is a mild antidepressant, and many people who do not realise they are a bit depressed and comfort-eating may no longer find the need.

I have a food obsession and the only things I've found to cope is just being hungry. I try and drink coffee, I think hot drinks help. I don't eat breakfast and just remind myself that the hunger I have is nothing -- it's a result of boredom and sedentary. I have enough nutrients in my diet that even one of my meals for a day would sustain me. It's not pretty, but that's the actual thing I do. What's that method called? Passive suffering? Reality check?

Also, if it costs money and is unhealthy, cut it. That's the number one priority.

Surprised only one other person has mentioned this! (well, OK, not really, since this is still kind of a weird tip)

The current gold standard for weight loss is a combination of medication (for appetite suppression) and following the advice of a registered dietician (for implementing the lifestyle changes that are required for maintenance). If you're in the US, you can search your insurance company's website for a list of RDs in your area that take your insurance.

The medication you want is semaglutide (brand name Wegovy), which was FDA-approved in June of 2021 for weight loss (it was previously approved for treatment of type 2 diabetes mellitus, under the brand name Ozempic; Wegovy is just a dose increase from 1.0mg to 2.4mg). Stephan Guyenet has a good article on the subject [1], which links directly to the FDA studies [2][3] that consistently find a previously-unheard-of 15-18% weight loss over 68 weeks.

You'd be taking this as a once-weekly subcutaneous autoinjection, and its function would roughly be described as appetite suppression (although hunger/satiety is a very complex mechanism, and it actually does a lot more than that). Your primary care doctor could prescribe this to you, assuming you can get prior authorization for it from your insurance (for me, they asked for my current weight and what I've tried previously, which was a lot). My doctor also recommended that I test my blood sugar regularly, since this can result in you not eating enough at first, which can cause issues.

The hard part with this approach initially would be getting a hold of the first 3 dose packs, since Novo Nordisk underestimated demand and was impacted by supply chain issues. I called around at every pharmacy in my local area, and found that my local Costco (supplied by McKesson) was the best at getting it in stock. NN focused their initial efforts on building up manufacturing capacity of the final two doses, so once you get up to 1.7mg you should be in the clear on this problem.

The second hard part (besides insurance shenanigans) is tapering off. That's where you start heavily relying on the habits your dietician helped you set, the lifestyle changes you've made, and good old-fashioned willpower. Ultimately, though, the consensus on most obesity experts is that since obesity is a chronic condition, most people who want to maintain the weight loss will need to stay on this drug indefinitely. Personally, I'm keeping an eye on the semaglutide subreddit [4] to see how this develops.

Exercise has a wide variety of health benefits, including assisting with weight loss, but many overweight and obese people find that it's hard to stick with (probably because carrying around the equivalent of a 30 kg. weighted vest means most of the movements you'd be doing require much more energy), and ultimately most of your weight loss is going to come from dietary changes. Also, losing weight requires you to eat less, which in the short term means you have less energy to exercise and it's much harder in general, and focusing on the weight loss will make it easier to exercise in the long term (because you're ditching the weighted vest). So I'd recommend starting with the weight loss first, and then you can work on setting habits around exercise as you continue to lose weight.

I'd also recommend that you work with a licensed psychologist who specializes in obesity to examine the factors that led you to develop the obesity in the first place, and work on addressing those concurrently. For me, this turned out to be chronic stress caused by multiple undiagnosed mental health issues, and getting treatment for those (which did include making other lifestyle changes) helped immensely. If you're in the US, Psychology Today's Find A Therapist tool [5] is good for finding someone.

I started at 132kg five months ago, and now I'm down to 111kg with 34kg more to go, and this is how I did it so far. It's a lot of balls to juggle at first, but setting those initial habits around weight loss helped me set more habits, which makes this easier.

One last thing I want to address: increasing the amount of oxygen in your environment may help give you some more energy (taking it from a canister very likely won't in practice, since those canisters are quite heavy and any affects would only last for as long as your increase in O2 saturation does, which would be about 1-2 minutes after you disconnect from it to do any sort of physical activity), but for many people it's not practical to redo their home/work's HVAC to add a concentrated O2 line. However, going outside regularly (where the CO2 buildup is very likely much lower than it is in indoor environments), as well as finding a good place to work outside when the weather permits (if you work from home), can definitely increase how energetic you feel and provide a wide variety of other health benefits.

So, to summarize: * Start by talking to your primary care, as well as a registered dietician * Try Wegovy if you can, it's pretty great * Talk to a psychologist who specializes in obesity * Carrying around an O2 canister probably won't help, but going outside probably will

Best of luck!

The single most important thing I had to realize was that sugar sucks. In consequence:

- ban sugary drinks. It's ok to slip, but just don't buy multiple at once. I sometimes go to the bakery to buy a sandwich and they have a formula with a free sugary drink: I don't even take it.

- avoid sugary breakfasts. Breakfast is an unnecessary meal. The later you break your fast, the later the first insulin spike, the less you'll store fat. I don't eat anything before noon. I just have black coffee or a tea, because they don't really break the fast.

- don't eat all day long. Especially not anything sugary. Stick to well defined meals.

- understand the role of sugar, insulin spikes, and fat storage.

- understand calories. Count them for a while to get an understanding of what you're eating. When I say "count", I mean "count", not "count and stop". It's important to get the feeling for calories and then stop counting as soon as possible.

- learn to read labels. You don't have to not buy anything with a bad label, but it's important to know what you eat. It helps you make informed choices.

- know the basics: you should not have more than 25g of sugar per day. That's 5 teaspons. One teaspoon is 5g. Fill a teaspoon and see what 5g of sugar is like.

- and look at the arguments of "trendy" things such as keto or intermittent fasting, you don't necessarily need to do them perfectly (unless that helps you), but you should take inspiration.

Nothing is absolute. You can slip. Just do your best and try to improve.

Why do humans have the capacity to be overweight in the first place?

The most effective way is to simply strictly (water) fast until you reach your desired weight. [You don't even have to be that strict and can drink some But most people in the modern world want "another" ("easier", "high-tech" etc.) way. Some magic exercise, pill, protocol, weird thing ... indulging in the myriad choices.

Why? Because habit-forming for adults is frikkin' hard. For some the best benefit-cost ratio is Bariatric surgery with all its nasty side-effects.

As with other addictions (loosely defined here) the optimal way (most of the time =/ effective way) is quite personal one has to account for the history, motivation, etc.

So for some an O2-tank might be the right trigger.

That's why - at the end of the spectrum - I'm even all for homeopathy if it facilitates a powerful placebo effect to change one's habit. It has by definition no side effects (except of course for nocebo).
