Go for slow carbs and grow slimmer and more muscular
Okay, it's only an animal study, and of course rats aren't humans, but even so. If the rats in the experiment became more muscular and slimmer by eating less-easy-to-digest carbohydrates, we want to know all about it.
Study
The researchers wanted to know whether a diet like this would help people who are on their way to becoming diabetic. So they fattened rats and then surgically removed sixty percent of their insulin producing cells. In the figures below the arrow indicates when the operation took place. After the operation the researchers gave half of their rats a high-glycaemic diet [refined sugar and carbs], and the other half a low-glycaemic [whole grains] diet.
The rats in the low-glyc group were allowed to eat as much as they wanted; the rats in the high-glyc group diet were put on a restricted diet. They put on weight so the researchers restricted their intake by several percent for the duration of the experiment. This way they made sure that both groups maintained approximately the same weight.
Results
The insulin and glucose levels were lower in the low-glyc group, and the adiponectin level was lower too. Adiponectin is a hormone that is secreted by healthy fat cells. It helps muscles to absorb more nutrients from the bloodstream.
