If you don’t have an established exercise routine, simply walking is the best first step toward weight loss. “Walking is a pretty good entry point for people,” says Gagliardi. This is particularly true if you have been out of the gym for a while and want to ease back into a workout routine. One small study published in The Journal of Exercise Nutrition & Biochemistry found that obese women who did a walking program for 50 to 70 minutes three days per week for 12 weeks significantly slashed their visceral fat compared to a sedentary control group. https://www.youtube.com/watch?v=hK2zC6BG4F8
Further, by building muscle - and thus permanently increasing our metabolic rate - we become walking furnaces, burning fat even while at rest. Given that muscle is a metabolically active tissue, it requires a continual turnover of energy to maintain, a degree of output that steadily targets our fat cells for fuel. The dilemma we face, then, lies in determining just how much cardio and weight training should be done to maximize the fat burning effect. One common theme that has emerged in reviewing the results of the many people I have trained over the years is the profound effect weight training has had on their weight loss success.
"Feeling stressed can wreak havoc on our bodies. It can cause our body to produce the steroid hormone cortisol, which can make you crave sugary foods that provide instant energy and pleasure. Short-term bursts of cortisol are necessary to help us cope with immediate danger, but our body will also release this hormone if we’re feeling stressed or anxious. When our cortisol levels are high for a long amount of time, it can increase the amount of fat you hold in your belly."
One study from the University of Adelaide in Australia suggests you may lose more weight when you work out towards the end of your menstrual cycle, as opposed to right when a new one begins. That’s because the hormones estrogen and progesterone tell your body to use fat as an energy source. "Women burned about 30 percent more fat for the two weeks following ovulation to about two days before menstruation," study author Leanne Redman says.
