fat AND ideal form

Yup, I was doing keto for over a year to lose weight. Got to a healthy weight, stayed there for 3 months, and decided I wanted to gain weight to help build muscle. Put on 20 pounds while still being on keto. Then lost weight again to look leaner. It's all calories in, calories out. However some people find certain diet types to be easier and preferable to others.

LOL, I'm 5'2" and hover around 100 lbs, and I've had trouble gaining weight my whole life. Eating more doesn't seem to help much. But I have noticed the more I eat, the more I shit. Perhaps that's where all my calories are going 😭 .

Research shows that small amounts of physical fitness during the day can be just as beneficial as a full workout

A 2019 review of 19 studies looked at this question, involving more than 1,000 participants. It found multiple, shorter “chunks” of exercise in a day improved heart and lung fitness and blood pressure as much as doing one longer session.

And there was some evidence these chunks actually led to more weight loss and lower cholesterol.

Pretty sure this guy can’t even count.

Eating in a deficit? Yes, counting calories? No. There's times I lose weight just because of activity load. Hell I did a 3 hour bike ride on Sunday that burned around 2000 calories. When ski touring season hits I'll probably lose a bunch of weight. I get that most folks can't do activities like that, but there's a lot more to fitness than just your body fat. If I loose weight due to exercise it's usually 10 lbs but over the summer I went from 180 to 165 without thinking once about my calorie intake.

It really is what peak performance looks like

southern elephant seal holds the record at 2hours

Don't want to think how the scientists made them compete for this record

Are we drunk or just 8 years old?

I'll fall back on my default null hypotheses here.

1. The effect is probably minimal if it exists at all.
2. If there is any effect, it is probably negligible if you are doing the big things right.
3. Your body is smart, and responds to changes in its environment with an eye towards improved survival and fitness. It is not a simple CICO machine.

So suppose we have an overweight person who is trying to lose weight. They hear about cold water exposure, and how being cold burns more calories. So they start running 10 miles every day at 5 am wearing nothing but a t shirt and shorts in the middle of winter. Then they go to starbucks, buy some hfcs with a touch of coffee, and go work at their office job that they hate because capitalism or something. Almost certainly, this person's jounts would start to give out quite quickly, but let's say they hate themselves enough to keep at it all winter. At the end of winter, I would be unsurprised if they gained weight. Sure, they exercised in the cold - but more importantly they were over training, consuming a poor diet, and living an otherwise stressful life. One of the body's best defences against coming hard times is to store calories for future use - by increasing appetite, decreasing subconscious calorie burning, and shunting resources towards fat storage rather than, say, growth and maintenance of muscle, skin, hair, etc.

On the other hand, suppose we have the same individual. They start with the premise that their body is already great, but they would like it to be better, and the way they will achieve this is via having fun and living well. Thus, their fat loss program consists of learning how to ice skate at the town park after work, going snowshoing on the weekends with their local hiking group, adopting a journalling routine before bedtime, and frequently inviting friends over for dinner parties where they make sure the emphasis of the meal is on protein and vegetables. They also open up to friends about how they aren't really motivated in their job, and their network of friends helps them gain the skills and industry contacts necessary to get a job that is more to their liking where they get to do interesting and meaningful work with other people whose company they enjoy. At the end of the winter, I would expect this individual to have lost fat despite exercising in the cold. While fat is good for energy storage and insulation, hiking and ice skating are activities where the body generally benefits from having a lower bodyweight - and warmth can be achieved via increased muscle activation rather than fat insulation. Meanwhile, they were spending a lot of time in beautiful natural environments, interacting with people they liked, eating healthy food, sleeping well, and working towards improving their lives in all aspects. "Things are good and I can expect them to get better" is the antithesis of the doom and gloom stress that will likely drive weight gain. Instead, the body will think "the present is not bad, and the future looks easy - and meanwhile, this extra weight is hindering my ability to move easily. May as well get rid of it."

This is why we find hot people hot. In the past when calories were scarce, a high bodyfat percentage indicated that in the hard times you were living in, this person had access to a lot of calories, and you could expect this trend to continue. These days, life is relatively easy, and storing excess calories is an indication that a person finds life to be hard. A lithe person's body indicates that they have rarely experienced difficulties beyond their abilities, and that they generally live a happy life. This is a good indication of genetic fitness, and hence, they are hot. Same reason why having good skin, healthy hair, a cheerful and outgoing demeanor, and perky tits are hot - they indicate a prolonged state of positive life circumstances which potential mates could generally count on to continue.

I was looking into that recently, specifically gorillas, just because it’s such a common sentiment that humans have to work so hard and eat so particularly to build muscle but gorillas are naturally jacked.

It turns out they have a lot going for them in that regard

So first of all they low key do actually strength train. They use their strength to break and process vegetation. These dudes will straight up rip a tree apart with their bare hands. It’s pretty crazy. It’s also how they spend most of their time.

Like they literally wake up at 6am, do a crazy workout, eat a ton, take a nap, then do another crazy workout, eat another ton, then go to bed. Every day. It's basically the same routine Arnold ran when training for the olympia.

The other thing that comes up is how they mostly eat plants but humans need tons of protein. This part is the most fascinating to me.

So humans have a concept of “essential amino acids (essential proteins)”. There’s like over 500 aminos in general, and for the most part if we need one for any particular bodily function, our bodies can just make them out of whatever. EDIT: this has caused some confusion further down, apologies. As I explained to another user I wanted to be selective about the depth of every specific biological mechanism for the sake of brevity. However I should mention the aminos are not created out of thin air, but through the breakdown of other proteins consumed in the diet. The exceptions are these 9 particular aminos which we require, but cannot create ourselves, so we have to get them directly from our diets.

Humans also have relatively pathetic digestive systems. There’s an entire large category of plant matter we consume that we simply cannot process, and it passes through us. We call this material “fiber”, and it’s still very important for us to eat, but nonetheless it is simply not broken down into energy or other building blocks.

Gorillas do not suffer from either of these limitations. Their bodies can produce all necessary amino acids, and they can break down fiber.

So with all this, when you look at their diet as a whole, (which is about 40lbs per day of plants, and keeping in mind the plants are simply more nutritive to them biologically, and their neutrality towards the specific amino profile of their food), when you crunch the math, they actually end up eating slightly higher than the daily protein value recommended for high level human bodybuilders.

That coincidence totally blew my mind. Like we’re so closely related and require the same basic conditions for muscle growth, but achieve it in such parallel yet unrelated ways. Totally awe inspiring

Yup. https://en.wikipedia.org/wiki/Blubber

Blubber is the primary fat storage layer for some mammals, especially for those that live in water. It is particularly important for species that feed and breed in different parts of the ocean. During these periods, the animals metabolize fat. Blubber may save energy for marine mammals, such as dolphins, in that it adds buoyancy while swimming.

Blubber has advantages over fur (as in sea otters) in that, though fur retains heat by holding pockets of air, the air expels under pressure (i.e., when the animal dives). Blubber, however, does not compress under pressure. It is effective enough that some whales can dwell in temperatures as low as 4 °C (40 °F). While diving in cold water, blood vessels covering the blubber constrict and decrease blood flow, thus increasing blubber's efficiency as an insulator.
