Article on how big of deficit you can safely maintain muscle at

[SouthPawSD]

Hey all, I mostly lurk around here but found something interesting that I thought I would bring up. In this article : baye. com/calculating-the-daily-calorie-deficit-for-maximum-fat-loss/
The main point is you can keep a deficit of [lbs of bodyfat] x [30] and as long as your withing this range, you don't have to worry about losing any LBM.
Thoughts, comments, opinions? Sorry if this has been discussed before, couldn't find anything using search

It's true for the "average joe" that has poor nutrition, don't exercise much, dont do much lifting and do do much cardio.

But we don't know the limit for someone who is active with lifting and/or cardio and has good nutrition. Everyone seems to agree that these factors increases the maximum fat mobilization, but no one knows the actual number since there is no research about it.

Keep in mind the specific foods and macronutrient ratios consumed by the subjects were far from optimal for fat loss, and that “moderate activity levels” is not the same as regular, high intensity strength training. The maximum rate is most likely higher for someone eating adequate protein and not overdoing carbohydrate intake and strength training would also contributes to maintenance of lean body mass when calorie intake is below maintenance level.

So what do you think this means to recommendations? To me it seems the advice of "500 cal deficit" would be for those approaching low bodyfats, and most of the people asking for advice have the ability to lose fat lbs much faster.

A good read on the topic.

I think common sense works best here, the fact that you know a 2000 calorie deficit isnt normal for a somewhat leanish guy. If a person has a massive deficit like that they deserve the consequences.

I believe Lyle McDonald debunked this a while back. Basically, with adequate protein and heavy lifting, you can forget that number
