8. Sleep more and stress less. Easy, right? This may be the hardest part. There are plenty of things you can try. Melatonin and or magnesium at night. Massages. Yoga. Meditation. Hot baths before bed. Black out windows and cooler temperature in your bedroom. A good shrink. There’s really no shortage of suggestions. It may be time to experiment if you’re not getting enough good sleep.
If you are taking the appropriate measures (e.g., eating enough of a calorie deficit for your age and body composition, stressing less, and working on strength training) and still not losing weight, and you also have other symptoms of hypothyroidism (such as constipation, fatigue, dry hair and nails), then it may be worth considering getting your thyroid levels checked," advises Dr. Peterson.
If you were very active in your younger years, you may have had some injuries. Like a spicy pepperoni pizza does after dinner, those injuries from your carefree days can come back to haunt you. These ghosts of injuries past show up in the form of early arthritis, bone spurs, tighter muscles, pinched nerves, etc. After our 30’s, new injuries also take longer heal. No wonder we slow down.
Sarah Mirkin, RDN, author of Fill Your Plate Lose the Weight, recommends 20 to 30 grams of protein per meal. "It’s important to take in that amount of protein at all your meals, and ideally include high protein snacks as well," Mirkin says. "This helps to prevent lean muscle protein breakdown that decreases muscle mass percentage, increases fat percentage, and slows the metabolic rate. Muscle burns calories. Fat doesn’t."
People naturally lose muscle after 40, especially women after menopause. Because muscle burns more calories than fat, this can slow down your metabolism and make it harder to shake those stubborn pounds. Strength-training exercises -- lifting weights or doing body-weight exercises, like push-ups and squats -- at least twice a week can help you keep those muscles.
