Weight Training Makes Mice (And Men) Lean and Mean
Researchers at the Boston University School of Medicine have shown using mice that weight training is very beneficial for weight loss. Using a mouse genetic model, the researchers found that an increase in type II muscle mass, which is associated with consistent weight training, reduces body fat.
The researchers used a genetic trick in obese mice to cause the mice’s muscle to enlarge just like they had been weight training. The results were fat loss and other signs of metabolic improvement throughout the body. Interestingly, the benefits were seen despite the mice eating a high fat and sugar diet and without increasing their physical activity.
This research supports my experience with weight lifting. I find that when I stop lifting weights for a month or longer, I gain weight very fast. However, when I have been weight training consistently, I can slack a little on my diet and still not gain weight. I also find that I have the easiest time losing fat when I focus my exercise program around weight training.

Hi Mike,
That makes a lot of sense since muscle uses more energy and will help keep your metabolism burning. I don’t use free weights but I do use resistance bands for strength training…..actually, besides the fat burning benefits, it just helps put me in a better mood.
Gotta love those endorphins. 
I agree. Weight lifting does seem to put me in a better mood as well.
