If you prefer a specific plan with specific rules, make sure it goes with your lifestyle, which, for most guys, gets increasingly complicated in your 40s with more responsibilities at work, with your family, and maybe even with your aging parents. A vegan diet can be hard to do in a healthy way if you live a grab-and-go existence. Meal prep is going to be a challenge if you’re never home long enough to cook. Don’t just pick what worked for a friend; pick what’s likely to work with your busy, over-40 lifestyle.
To jumpstart your weight loss, the biggest focus should be to develop habits that will help you build or maintain your muscle mass. "The most effective way that women over 40 can boost their metabolism is by building muscle through weight-lifting and resistance training," says Dr. Peterson (more on that to come). But nutrition and sleep habits also play a role here.
2. Exercise More. Contrary to what your body may want to do, you must exercise more regularly as you age, not less!  If you’re finding yourself slowing down, gradually start ramping it back up.  It’s not a good idea to go from taking an occasional walk to running a 10K.  That’s a fast track to getting an injury.  But start finding ways to fit more physical activity to your life.  The more you exercise, the more insulin sensitive you become (that’s the opposite of insulin resistant!)
Gluten and dairy are two of the biggest culprits behind the ever-increasing rates of chronic illness, autoimmune diseases, and obesity. Gluten has been linked to increased inflammation, leaky gut syndrome, sleep disturbances, mood fluctuations, and skin issues.21,22 Consuming dairy can lead to inflammation, gut issues, and increased risk factors for a number of health problems. Banishing both gluten and dairy is one of the number one actions I recommend for you to take control of your health and your weight. To learn more read my book, The Autoimmune Solution.
Let's get down to business: If you're having a hard time achieving your weight-loss goals after 40, these 16 expert-backed tips for losing weight in your 40s are totally doable and can nudge your body in the right direction again. (And, tbh, they're wise for anyone looking to move the needle to keep in mind—not just those over 40.) You'll be on your way to a stronger, healthier you in no time.
Yeah, you've probs heard that diet tip before—as it's wise for anyone trying to lose weight. Fried foods contain a whole lot of fat and contribute to weight gain—simple as that. But again, in your 40s, you deal with natural physiological changes that make it *even* tougher to shed excess weight, so overdoing it on fried foods has larger consequences. "A 20 year old can get away with eating empty calorie meals. A 40 year old usually cannot on a semi regular basis," Mirkin points out. "Until we are age 20, [our] bodies are building muscle. After age 20, it stops."

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."

As you enter your forties, you are also entering perimenopause, when levels of your sex hormones progesterone and estrogen decline. Besides regulating your menstrual cycle and reproductive functions, these hormones also impact restful sleep and relaxation. A decrease in progesterone and estrogen levels may lead to sleep disturbances, restlessness, and insomnia.1 Because changes in sleep patterns have been associated with weight gain, sleepless nights may make weight loss increasingly difficult.2
Remember how we said that the more muscle you have on your body, the better your metabolism works? Having more muscle increases your resting metabolic rate (RMR). This helps you burn more calories at rest—which is what you want if you’re aiming for weight loss after 40. So if you’ve been avoiding those weight machines or dumbbells, now’s the time to dedicate yourself to strength training. It is never too late to start strength training! If it is new to you, take advantage of any free personal training sessions that might be offered when you join a local gym or health club. This is often to familiarize you with the equipment and the layout of the facility, but can be a useful tool to get you started on a routine. Of course, if you have the finances to hire a trainer for a few sessions that’s another way to go.

Once you hit 40, losing weight can feel like a lost cause. Dr. Robert Kushner, director of the Center for Lifestyle Medicine at Northwestern Medicine Center in Chicago and author of “Six Factors to Fit: Weight Loss that Works for You,” told TODAY that the total amount of calories burned every day diminishes for most people with each passing decade.


When you’re busy with work, kids, and life, you can be tempted to grab food on-the-go or multitask through a meal. But you’re more likely to overeat -- and be hungry again soon after -- if you don’t focus on your food. Sit down for meals and tune in to what’s on your plate (not what’s on your TV or computer screen). That helps your brain realize when you’ve had enough.
