I'd say it's an incredibly strong claim that they aren't negligible. Most research I'm finding says that your BMR may drop by like 10% with a classic calorie restricted diet (which itself accounts for about 75% of total calories burned in a day). So what are we talking here at most? 150-200 calories a day if a diet is able to completely stop a decrease in BMR as you lose weight? Less if it's not? What's the line that makes it worth it? A 100 calorie per day optimization is not worth it to me when I have to drop 500-1000 a day to have any real weight loss.
