What's interesting about this post isn't the actual diet advice, but the guidance to track and see what works for you. Different people react to fasting differently - some continue to burn calories and drop weight, some just go into starvation mode, have their BMR crash through the floor, and end up exhausted all the time because their body is fighting like crazy to conserve energy.

I do a lot of rock climbing, so most of my body is muscle. I'm currently floating at 170 lbs, but would love to lose 10 lbs so I can get up the wall faster. I think that fasting might be foolish because my body needs energy for climbing. In fact, if I wait too long after eating lunch, I tend to get really hungry during climbing and I start yawning a lot (not sure why).

I'd love to see something like this applied to the goal of gaining muscle. I've been a twig my whole life. In college, I gained 20 lbs of "noob gains" and then tapered off severely. I've maintained that weight, but can't gain more with any reasonable effort. Dear ddv, You've got a potential million+ dollar business in the works. In fact, I'd quit my job to be a programmer on your team.

The conventional advice in this situation I believe is: unless you're eating enough that you're also putting on some fat, you're not eating enough... Also consider the Gallon Of Milk A Day method.

Just for what it's worth, there are several Soylent-like meal replacement products that are explicitly formulated for ketogenesis. This could be an aid for a person who wants to try a keto diet without having to research a lot of new recipes.

Quite a few people do keto long term for overall health or maintenance after weight loss (or without weight loss in the first place). I have never used it for weight loss but those who do often talk about the rebound in weight you mention with short term diets. This is sometimes one reason they end up making this more a lifestyle change than a short term diet for them. As you get adapted keto becomes very manageable, and the higher intake of fat can make it easier to consistently consume fewer calories than they used to eating carbs.

Atkins is not a keto diet. Atkins starts keto, then reintroduces carbs. Weight loss is simple: calorie deficit. However, switching from carbs to fats and taking advantage of some of the metabolic processes your body has to offer makes the process easier for many people. Calorie deficit with less hunger and decent energy. It helps a lot.

>Weight loss is simple: calorie deficit

Not that simple. People touting this are usually genetically endowed with great metabolism. I've tried this many times and reach a plateau pretty quickly and have to keep decreasing calories until it's not practical anymore.

On the other hand, watching the glycemic index/load does the magic for me.

Might be lacking glucose; I believe that is why marathon runners eat glucose before they run.

A word of advice to those attempting a Ketogenic diet: get your blood work done on a regular basis. If possible, get heart scans done once a year. It's easy to slip into a sloppy version of the Ketogenic diet, at which point you're consuming lots of unhealthy fats and carbs, you triglycerides and cholesterol could shoot up and put you in shit street. This is a strict diet.

What is an unhealthy fat? Also, by definition, if you are eating more than very minimal carbs, you aren't on a ketogenic diet. Honestly, and with no sarcasm intended, I think your advice would be similarly correct for anyone considering eating bread, or white noodles/rice - get your blood work done on a regular basis, and heart scans done once a year, your triglycerides and cholesterol could shoot up and put you in s…

> What is an unhealthy fat?

Fat consumed with high levels of sugar.

Not everyone has the capacity to be strict with their diet, habits, or health in general. These people might still attempt the Keto diet.

The Ketogenic diet gets approached by lots of people with mental health issues (bipolar for one), and people who have issues being strict with their diet.

Advising them to get their blood work done, and heart checked is normal, and sensible. Getting your blood and heart checked regularly is a healthy habit, and provides vital feedback to understand exactly how your diet is impacting your health.

This is delightfully nerdy and overly analytical, but I can't believe someone would go to the extent of creating this yet never think to look for counterarguments against their dieting regimen. Doing this would have given him the answer much sooner.

Trying to figure out how the consumption of certain foods correlates with weight gain/loss is a waste of time because it's simply the caloric content, not the macronutritional content (eg protein vs carbs vs fats). There are dozens of studies showing that only calories matter for weight loss, including vs low-carb, low-fat, and more[1].

The author is acting like each food has arbitrary properties that make them food or bad for weight loss. It's a good reason to play with ML, but it's easier to just count calories. I hate seeing people go down the "good food/bad food" path of thinking because they end up overanalyzing the shit out of everything they eat and for no good reason.

The glycemic index doesn't realistically matter either for a ton of reasons. It hasn't been taken seriously as a useful marker when chosing foods for quite some time now. It's not a reliable indicator of anything. I posted a summary a few years back that debunks all the insulin/GI spike voodoo[2].

Low carb diets work, but they only work because they're a trick to get you to reduce calories. Look at what you're eating and remove all the carb foods. Notice how much your calorie intake dropped. It's a simple way of losing weight without counting calories, but that's it. The weight loss on keto, atkins, etc have nothing to do with carbs, and everything to do with calorie restriction.

It's worth noting that low carb diets have great health benefits, however [3].

What do you mean by glucose exactly? What kind of foods should I be eating? I usually just get whatever for lunch at my company - tacos, Indian food, whatever is being served.

This is probably it -- after exhausting the contents of the digestive tract, the body resorts to glycogen reserves in muscle and the liver. Your glycogen reserves are your "blood-sugar" and consuming them requires a burst of oxygen, so depleted oxygen typically follows low blood-sugar, ergo yawning.

Energy gels are usually high-energy but low-everything-else, which is probably what the parent is referring to ("eat glucose"). This is to supplement blood-sugar levels without affecting the digestive process too much, or, more to the point, without affecting their marathon performance.
