Isotonic sport drinks have their place in the world of health and fitness, but they do not belong in the area of fat loss.
I understand the logic some people use. If you want to lose fat, training harder and going for a little longer would be a good idea. If a ‘sport’ drink says it will keep you going 33% longer, why wouldn’t you buy one?
Again, as always, it comes down to the insulin sensitivity of your muscles. These drinks contain a lot of sugar, the one thing you want to avoid if you’re looking to lose fat.
Regardless of whether you’re in the middle of an incredibly tough fitness session, until your muscles are sensitive to insulin again….NO SUGAR!
If you have too much body fat, you’re at the stage where your muscles are resistant to insulin. When you drink a high sugar, isotonic, 33% longer, cherry flavoured and shiny labelled drink – your blood glucose levels rise dramatically. Ideally, your muscles quickly take on the glucose for energy (they need to be sensitive to insulin for this to happen) and as such…you can go for a little bit longer.
However, as you’re currently in an insulin resisting state, the glucose can’t get to your muscles and will be stored in your fat cells instead.
Water, on the other hand, is great for fat loss. Especially as it promotes the effective circulation of fat metabolizing hormones after a workout.
It’s also a lot cheaper!
