Ever feel like your metabolism is working against you, making it impossible to lose weight?

Metabolism is the rate that food turns to energy and gets used by the body as fuel. A higher metabolism means your body burns more calories to function—a key characteristic for weight loss.

Some diets can cause your metabolism to slow because they don’t provide the right kind or amount of protein to support muscle tissue. You may lose weight, but it’s the wrong kind of weight. In addition to burning some fat, your body is also breaking down muscle for energy. Decreased muscle mass results in a slower metabolism, making it harder to reach your weight loss goals.

Fortunately, there are ways you can maintain muscle and support a high metabolism while burning fat.

Because muscle is the biggest factor when it comes to boosting metabolism, it’s important to engage in exercise. For optimal muscle growth, research supports intense resistance or weight training (1).

In addition to intense resistance training, the right kind and amount of high-quality protein is essential for building muscle and boosting metabolism. Whey protein has especially been shown in studies to boost metabolism during weight loss longer than other types of protein such as soy (2,3).

Don’t fall victim to diets that slow metabolism. Rev metabolism up to high-speed and build muscle by engaging in intense exercise and consuming the right amounts of high-quality whey protein like Isagenix IsaLean® Pro.
