Changes in your activity levels are one of the main reasons that losing weight after 40 may be more challenging than before. Like many women, you may be putting others first and simply not finding time to exercise. You may also notice that your joints can no longer handle the same activities as before. However, a lack of exercise can lead to muscle loss and fat gain.
Additionally, attempts to lose weight on low-calorie diets can lead to even more lost muscle. Studies have found that regular resistance or strength training may be a better alternative than your daily runs to preserve and gain muscle — even when coupled with a low-calorie diet. Aerobic exercise is still important, just don’t make it your only form of activity.

1.  Eat less added sugar, processed food and refined grains (white bread, bagels, pasta, white rice, you know the drill). A lot less.  According to the sugar science department at UCSF, added sugar is hiding in 74% of all packaged food.  And, the majority of carbohydrates in the typical American diet is made of refined grains.  This means reading labels folks and knowing how many different names there are for sugar.  Just because it’s called “agave nectar” or “cane juice crystals” doesn’t mean it’s any better for you than the white granulated stuff.  Your body doesn’t know the difference and once you eat it, it’s all the same to your pancreas (the organ that produces insulin in response to sugar).  Click this link to see 61 different names of sugar then run to your pantry and read the ingredients on your packaged food.  Prepare for a rude awakening!
A 2014 study found that the type of fat we consume might make all the difference. Participants in the study were asked to eat 750 extra calories every day for seven weeks. Those having excess calories from saturated fats had activated cells that promoted fat storage in the belly and increased insulin resistance. However, individuals who had a high consumption of polyunsaturated fats found in fatty fish, nuts and seeds, gained less abdominal fat and were more likely to increase muscle mass instead.
Between desk jobs, commutes, and family activities, many 40-somethings don’t have a lot of free time to work out. But it’s important -- for your weight and your overall health -- to fit in at least 2 1/2 hours of moderate physical activity (like brisk walking or light yard work) every week. Pencil times in to your calendar, and make them a priority.
