At what bodyfat generally does refeeding become beneficial? Is it ever a good idea for someome who is say 19-20% to refeed every 2 or so weeks at a deficit of around 500?

A refeed can also be necessary when glycogen and carb levels are down and have been down for a while, it's not solely about body fat percentages. Having said that, at 19-20% there's not much need for a refeed unless you're going super low carb or keto. Your hormonal response to dieting at this BF is not attempting to reverse what you're trying to accomplish so the refeed would only be beneficial psychologically, again assuming you're not super low carb/keto.
Personally, I would only recommend a (carb) refeed after several consecutive days of very low ( < 50g) / no (starchy) carbs at all, regardless of BF%. If somebody is consuming for example 150g carbs/day, even at a low BF%, what are they really refeeding? Glycogen stores won't be depleted; the dieter would only be 'topping them off' with a refeed.Quote:

Also, the leaner one is the harder it is to mobilize fatty acids for oxidation bc of the hormonal response to dieting. Carbs affect this to some degree but even in the presence of carbs we know the leaner you get the harder it is get get more lean. A refeed (not necessarily carbs in this instance) can help slow this response. Maybe it's better termed "over feeding"???
So a guy at 5'9'' 185 roughly 20% bf cutting on 2100 calories and 150 carbs should not ever worry about incorporating a refeed?
You're right doc. We don't want to confuse people - there are carb refeeds, and there are purposeful caloric overages (not necessarily restricted to the carbohydrate macronutrient). When I talk about refeeds, I refer specifically to carb refeeds as personally, I have no need to cycle the other 2 (deloading etc. aside).Quote:

@150g carbs a day, you don't need a carb refeed specifically. However, you may want to incorporate a higher calorie day once every 7-14 days. If you want the caloric increase to come by way of increased carbs on that day, go for it - that's completely up to the dieter.Quote:
