Personally I would avoid anything with a GI higher than glucose. There is mounting evidence that some ultra high GI foods actually cause a short term decrease in insulin sensitivity, so your blood glucose sky rockets, but the glucose is not getting used effectively. Since impairment of glucose utilization will also impair insulin-stimulated activation of leptin gene expression and leptin secretion, these foods may be a poor choice for refeeds.
For sure, there is a lot more to long term energy balance than just leptin. But unless you have access to means of manipulating your acylation stimulating protein, adipsin, complement factor C3, diacylglycerol acyltransferase, perilipin, adiponectin, acetyl-coenzyme A carboxylase 2, Hmgic, cerulenin, or a host of other in vivo factors which may be involved, I think leptin manipulation via increasing blood glucose levels AND uptake is still the cheapest and most readily accessible method to prevent "hitting the wall" of fat loss. It's not a magic bullet, but it helps.
