I was talking mostly about the post workout simple carbs not being a good idea for the obese. They don't need it to put on muscle or prevent loss, and it wouldn't get shuttled to the muscle because of impaired insulin function. Not to mention they most likely already have high insulin levels are getting plenty of anabolic effect, and actually need to get those chronically high levels down.
Obese individuals need to ingest some type of simple carbohydrate after a workout. Muscle glycogen is depleted in their muscle, just like everyone else.
Research shows that one of the keys to recovery is to replenish muscle glycogen in the muscle. If that is not taken care of, the individual takes longer to reovery.
Timing is EVERYTHING
As Jay Robb (nutritionist) stated, "Insulin is a fat maker." When insulin levels are high, fat is being stored on the body.
The EXCEPTION TO THE RULE is in the post workout phase. At this time, the body is poised to shuttle nutrients to the muscle cell...EVEN WITH OBESE individuals.
Also, working out for obese individuals increases the sensitivity to insulin...meaning they are LESS RESISTANT.
Obese individuals DO NEED to put on muscle and prevent muscle loss. One of the problems is the obese individuals have a greater ratio of fat to muscle.
What these individuals want to do is replace fat with muslce. Increasing muscle mass increases you metabolism. It like putting a bigger engine in your car that burns more gas.
An obese individual DOES want to prevent muscle loss, just as anyone else does.
To find out for sure what you insulin live is, get a glucometer and take and test yourself.
The time to spike insulin levels, even for obese individuals is after a workout. This helps replenish the muslce, prevents muscle loss, and builds muscle.
Some experimentation is necessary in finding what works best for you. The Performance Zone is an excellent book on what to ingest prior,during and after a workout.
