Any calorie based study when it's self reported should be highly suspect of being false.
12% reduction of what? The basal metabolism? Were the people overeating before? How many calories on average?
I never get this "calorie restriction" term. What does it mean? I have a BMI of 20. Should I reduce my intake by 12%? When do I stop reducing? I want to live longer. I would also like to build some more muscle, ideally to a BMI of 22. What if I gain 10lbs of muscle then restrict?
When you put on 10 lbs of muscle, presumably your baseline will be slightly higher than it was prior to that (extra muscle requires extra calories to maintain), but still less than what it took to put that muscle on quickly and efficiently. I have no clue how much you should expect that difference to be, I'm sure many a bro scientist has opinions on it, some of which may be reasonable. Bulking and cutting is a classic technique in bodybuilding, however, typical cuts go on for a few months at most as opposed to 2 years.
One major takeaway from this study is that on average, you will be just as strong as when you started calorie restricting even though you will have lost muscle mass. It is theorized that your muscles will have become more efficient, so if you put on more muscle after a long period of calorie restriction you will be considerably stronger than if you had skipped the calorie restriction and just added the muscle. Food for thought.
Does any one find hard to eat a lot of protein (150g) in a 8 hour feeding window? I hate to live off of protein shacks.
Oh, and learning to cook meat/protein so it is tender, browned, flavorful, and seasoned properly. It also seems like acid is way under-utilized in a lot of lazy / American style cooking. Helps a lot with palatability and digestion to use lime juice, rice vinegar, and other acidic ingredients during the cooking process.
Eat more veggies, too. They are full of digestive enzymes, but most veggies don't add too many calories.

I did a bit of a double-take at the headline because it seems to imply that one can grow stronger while calorie-restricted, which is contrary to common practice around strength development - caloric surplus is generally understood to be necessary for muscle growth. I've only read the abstract, but the title as I interpreted it seems misleading: > One study showed that individuals on calorie restriction lost muscle ma…

One of my favorite studies, an oft-replicated and cited study, tracks several hundred people who claimed to be "diet resistant". Using a technique invloving "doubly-lableled water" they were able to determine that every single person in the study who claimed to be diet resistant was overreporting their exercise and underreporting their calorie intake: https://www.nejm.org/doi/full/10.1056/nejm199212313272701 Of cours…
Have any similar "favorite studies" on hand about alcoholics who underreport alcohol use and overreport abstaining? Punching down is a favorite pastime of mine too btw :)

Do you really need that much protein though?
That’s quite a contentious question, there aren’t that many good studies, and they are difficult to do well
If people lost 20 lbs in the first year of a 12% calorie restricted diet then that means that this study took place among people who were already obese (which seems extremely relevant). Anyone who is in good shape and not 6'8 is in no position to lose 20 lbs without serious risks to their health, aside from vastly decreased muscle strength. It is interesting, but not very surprising, that obese people with atrophied muscles don't lose "strength" by cutting calories and losing some muscle mass, which is very low to begin with.

> which is contrary to common practice around strength development This belief is already changing in bodybuilding and strength circles. Surprisingly, the fitness influencers on tiktok are leading the charge in changing minds about this.
That Ukrainian guy on tiktok who only weighs around 80kg but can deadlift over 270kg.

Wrestling seems like exactly the wrong thing to cite here, since it's generally not done in openweight, and if you're wrestling in traditional weight classes then what's described here is hugely beneficial - you can drop a weight class but not lose strength.
Also your opponent would have an advantage of you being lighter, which affects the results
