Hormonallly, horses overweight and predisposed to lami associate with high leptin levels - you want reduced leptin production, stimulated by increased exercise. Leptin is produced in adipose tissue, particularly brown, afair.
The initial discussion was why people didn't allow their horses to drop weight - whilst I agree many are obese and would benefit from weight loss schemes, I just don't think it is good management to use winter to do this, as weight loss is better achieved through exercise and feeding for the workload than by just cutting food intake. Better for the whole metabolism.
On my phone so can't do any paper research, will do though as it's interesting.
yes, the leptin level is one of the factors in horses developing EMS etc and the current vetinary advice is reducing weight by a strict diet and exercise programme to manage the condition. Depending upon the horse and circumstances a seasonal reduction in weight can 're-set' the metabolism.
Relying on exercise alone to maintain a steady weight can be quite a high risk strategy - it only takes a domestic crisis or injury at the wrong time of year and you can very very quickly find yourself in a lot of trouble with a good-doer tipping towards laminitis.....
