The EXACT System To Lose Fat And Build Muscle Over 40

May 05, 2026

A lot of the information you see about muscle building and fat loss is aimed at people who've been training for years and have unlimited time to work out. But I know there are busy professionals who aren't bodybuilders or athletes who want to lose fat and build muscle. That's the most common request I get from my clients over 40.

I'm going to show you the system I've been using with my clients to help them get lean at any age.

Using The POWER Framework For Body Recomposition

Hi, I'm Ivana and I've been a fat loss coach for over 25 years and a certified strength and conditioning specialist since 2008.

I usually tell my clients to focus on body recomposition because that's what they want — less fat and more muscle, or at least enough muscle to get some definition. And I'll use something called the POWER Framework to help you get it. It's five science-backed principles that support your physical and mental health for muscle building and fat loss.

I've put this all together in the Lean and Strong 40+ Plan which is FREE HERE.

P — Prioritize Nutrition for Fat Loss

When it comes to fat loss, you need to prioritize nutrition because you want to create a moderate calorie deficit to lose fat without draining your energy or performance in the gym. Unless you have a couple of hours every day to exercise — and I'm pretty sure you don't — it's very hard to burn off as many calories as you need with exercise alone. And I also want you to remember that your primary exercise for gaining muscle is strength training. So it's less about calorie burning and more about building a bigger metabolic engine.

And even though a calorie deficit is what you need to lose fat, I don't want you to get into that mental battle of eating, burning, eating, burning. This creates a bad relationship with food and it's not very effective anyway. Just as an example, the average doughnut has about 300 calories. If you weigh, let's say, 170 pounds, you'll need to walk for about an hour at a moderate to brisk 3.5 mph pace to burn off those calories. And I'm not even saying you shouldn't have donuts or cookies or chocolate or French fries or whatever treat you prefer in small doses. Believe it or not, I encourage you to keep them in your nutrition plan, but have them less frequently and in smaller quantities.

Plan treats rather than going off the rails once in a while. Think about your portion size. You definitely want to share a very large cookie with a friend, or eat a small amount now and leave the rest for tomorrow or the next day.

Because that first bite is the sweetest. The first taste is the most satisfying. There are diminishing returns as you eat more and more of the same food, no matter how delicious it is. So you want to eat slowly. Pay attention more. Stop when you're starting to feel satisfied.

Mindful eating goes a long way to keeping your calories under control naturally.

Build Your Food Freedom List

So, what do you actually eat? I want you to create what I call the Food Freedom List. You'll put together a collection of foods based on the following questions:

1. What are your five favorite staple foods you could eat regularly?

These are healthy options you could happily eat all the time. I personally eat potatoes or sweet potatoes nearly every day because I love them. And potatoes have one of the highest levels of satiety of any food. If it keeps you full, your appetite stays under control and you eat fewer calories overall. I also love avocados and macadamia nuts, both of which are calorie-dense. I keep the servings relatively small — for me, it's not for fat loss, but because of the fiber. I also love salmon. I'll often have a nice fillet if we go out to dinner, and lately I've even started to have a can or two of wild sockeye salmon every week. And olives are another staple for me.

2. What are your five favourite lean protein sources?

Salmon isn't that lean because it's higher in fat and calories. So for lean protein sources: Greek yogurt (that's usually what I have in the morning), cottage cheese, which I put on potatoes or sweet potatoes, chicken breast, of course, egg whites, and extra lean turkey breast — I usually have that as part of some kind of nacho-like meal.

3. What five vegetables do you genuinely enjoy and want to eat more often?

I enjoy asparagus, sugar snap peas, broccoli, zucchini, sprouts, alfalfa or bean sprouts. All of those are kind of refreshing to me.

4. What five fruits do you genuinely enjoy and want to eat more often?

Blueberries — I have those practically every morning with my Greek yogurt — raspberries, watermelon when it's in season, strawberries (but only when they're fresh in the summer), and I really like mango, but it's hard to get it at the right ripeness. I sometimes have frozen mango.

5. What are your five favourite treat foods that feel truly worth it?

You're thinking chips or donuts, wine, beer, fries. For me, it's milk chocolate, cheesecake, fresh soft-baked chocolate chip cookies, and ice cream — generally Ben & Jerry's Chocolate Chip Cookie Dough, Half Baked, or The Tonight Dough (O'Canada for Canada). All of those are truly worth it, and I always have those in small servings.

6. What five treat foods could you easily live without?

What doesn't actually satisfy you, or isn't really worth the calories to you? I don't eat French fries or potato chips. I have GERD — that's acid reflux issues — so fried and really greasy food doesn't feel good for my stomach. I'll sometimes make an exception for fried plantain if I'm on vacation in the Caribbean because that's so good. That's also why I don't do donuts. I almost never have pizza unless it's one of those fancy pizzas you cut with a fork and knife. And I don't eat any red meat — it just doesn't agree with me and I never really liked it.

7. Which foods or habits tend to throw you off track?

Think of your trigger foods. Maybe it's social settings for a lot of people. Late-night snacks. Evenings have always been harder for me — that's a really common problem. Most of my clients work on strategies to avoid eating after dinner.

I brush my teeth and do a fluoride rinse after dinner so that it wouldn't taste good if I tried to eat anything. Some of my clients have a fruity herbal tea as a nighttime ritual, or a small protein bar, or yogurt with fruit as a post-dinner routine to break the habit of mindless snacking in the evening.

I don't really have trigger foods anymore because I spent years working through those issues with restricting certain foods and using food for emotional support. That Ben & Jerry's ice cream I mentioned — in the past, I wouldn't have been able to have a small bowl without going back and finishing the entire tub. And sometimes two tubs. For the record, one tub is about 1,220 calories. Two tubs is 2,440 calories. That's more calories than I need for a day. Now I can have a small bowl and leave it. To me, that's real food freedom.

And that's what I want you to achieve, too, eventually. It does take time.

How Much Protein Do You Actually Need?

Remember that what you eat affects everything: muscle building, fat burn, energy levels, recovery, and even sleep. Take care of the physiological, and the psychological becomes easier. It starts with planning satisfying meals that keep you full. That makes it easier to eat less naturally. Then you're less likely to give in to your habits and cravings, most of which are psychological.

Focus each meal around protein for a total of 0.7 to 1 gram per pound of body weight, or 1.6 to 2.2 g per kilogram per day. This applies to active adults who want to build muscle and lose fat. Remember that it's a range, and 0.7 g per pound can be plenty for you. I usually keep my clients on the lower end if they weigh 180 to 200 lb — it's just so much protein to eat. Or if they're not already used to eating very much protein, it can be a big jump, so you want to do this gradually.

I weigh around 135 pounds at 5'10", and I usually get around 120 grams of protein divided into three meals — about 40 grams of protein per meal. Sometimes a whey protein isolate shake, just plain with water after my workouts, but not always.

Here's what my day looks like:

  • Breakfast: Greek yogurt, blueberries (or raspberries), macadamia nuts (or almonds, cashews, pistachios, or sunflower seeds)
  • Lunch: Canned salmon or cottage cheese with potatoes or sweet potatoes, a couple of vegetables (maybe sprouts or leftovers), and almost always olives
  • Dinner: Either lean ground turkey mixed with black beans, or chicken breast with vegetables and sweet potatoes or potatoes. Sometimes noodles, and occasionally an omelette with a couple of eggs and extra egg whites with mushrooms and potatoes

Protein keeps you fuller for longer and you'll be less likely to develop cravings later on. It also preserves your muscle mass, which is essential if you're over 40.

To maximize your muscle building, it's best to distribute your protein in at least three meals — you're keeping a consistent supply of protein for muscle protein synthesis.

Not getting enough sleep increases your ghrelin level — ghrelin is the hormone produced in your stomach and pancreas that's associated with stimulating hunger. So be mindful of that if sleep is an issue for you. And since fat is 9 calories per gram compared to carbs and protein at 4 calories per gram, it adds up more quickly. So while you want the protein, you also need to reduce your calories slightly to get yourself into a calorie deficit to lose fat.

The Role of Fiber in Fat Loss

Fiber can also help. Because most fiber isn't absorbed, those calories pass through. Insoluble fiber from vegetables and wheat bran acts as a physical barrier and can trap some fat and carbs, so a small part of those calories pass through unabsorbed as well. Soluble fiber — the kind you find in oats, legumes, psyllium, chia seeds, barley, and apples — forms a gel-like substance in the gut that slows digestion and absorption of nutrients. This is one of the ways that regularly taking psyllium helps reduce your cholesterol levels. Definitely something you want to keep an eye on after 40, as LDL levels are now causally linked to cardiovascular risk. Most fiber sources are low in calorie density, so they fill you up without many calories.

So, does this mean you don't have to count calories? Maybe. I've seen lots of people lose fat just by putting the focus on lean protein and foods with fiber, primarily vegetables and fruit. Having more nutrient-dense, low-calorie-density foods, and fewer ultra-processed foods, is certainly a great start. For most people, that will naturally put them into a calorie deficit without counting calories. But the leaner you are, the more specific you need to be to go further. So I do recommend that most of my clients track their calories and macros for at least 3 weeks.

O — Optimize Your Strength Training

Even if you've got your calories in check, you still want to pay attention to exercise. And for muscle, it's all about progressive resistance training. It's actually way more important to get that muscle stimulus than to eat protein. You can't just force-feed yourself protein and grow muscle. You need to put in the work consistently at the gym or at home to build muscle.

For me, strength training over 40 isn't optional if you want to stay lean as you get older. Maintaining your lean muscle mass as you age will keep your metabolic rate as high as it can be. Muscle burns slightly more calories than fat all the time. More muscle means more calorie burn. Muscle also supports a healthy metabolism, increases insulin sensitivity (which goes down with age), improves your joint integrity, and it builds bone density.

Research shows that even adults in their 70s and 80s can build significant lean mass with the right training plan. In your 40s and 50s, you're in the perfect window to build and protect muscle against bigger losses later on.

Two strength training sessions a week is the minimum health recommendation, but if you're serious about building muscle and feeling great after 40, then three to four workouts a week is a bit better. Full body workouts are a great option, especially if you're training on alternating days like Monday, Wednesday, and Friday. The programs I put together for my clients generally hit each major muscle group twice a week with only three workouts per week.

The six major muscle groups to train are: legs, chest, shoulders, back, arms, and core/abs. When it comes to exercise selection, focus on compound movements — exercises where you're using more than one muscle group and involving more than one joint, like lat pulldowns, chin-ups, deadlifts, chest presses, and seated rows. A bench press works your chest, front shoulders, and arms. A deadlift works your glutes, hamstrings, back, core, and forearms. You get more muscle involved all at once.

Your weight training sessions don't need to be long. 25 to 40 minutes of actual weight training with maybe five minutes at the beginning for warming up and mobility, and five to ten minutes at the end for mobility and stretching, is great. Unless you're competing in bodybuilding or powerlifting, you don't need more than that consistently to get amazing results.

Progressive Overload: More Than Just Adding Weight

Use progressive overload. You probably think about progressive overload as lifting heavier weights, adding weight to the bar — and yes, that can certainly be part of it. But as you get more experience with weight training, it's not always easy to add more weight. So what else can you do? You can increase the reps you're doing, or slow the movement down and increase the time under tension. You can also increase your volume — the amount of work in sets and reps you're doing over the course of the week. You can also increase your workout density by shortening the rest period.

Sometimes your body adapts over time to any stimulus, so you do need to eventually change your program. That doesn't mean every session or even every month. Usually six to eight weeks is a good time to make a change. That way your body has time to get better at the exercise you've been doing and you don't get too bored.

Generally, you'll want to keep your rest between sets no more than about 90 seconds — maybe 2 minutes or so if you're specifically working on strength in that session. But you do want some rest. If you don't leave enough time between sets, you won't be able to lift as heavy a weight or do as many reps.

W — Walk and Move Daily

While strength training creates the main stimulus for muscle, most of your daily calorie burn actually comes from movement outside the gym. Non-exercise activity thermogenesis (NEAT) is the small movements you do throughout the day — walking around your home, cleaning, folding laundry. A lot of people really get into counting their steps. Most of the health benefits in terms of health risks and longevity seem to max out around 8,000 steps per day. But if you're trying to lose fat, 10,000 steps certainly won't hurt.

And as another bonus for fat loss: if you feel like you're constantly hungry in a deficit — and that's common — a short walk can help reduce your hunger and manage your cravings. Walking is low impact and it doesn't add to the training stress on your body. It can actually help you recover from your weight training sessions. Think of it like oiling the hinges on a door. Regular movement keeps everything gliding smoothly.

In your 40s, you may have noticed more pain and stiffness in your joints. Some of that is the natural wear and tear that comes with age, but I say it's better to wear out than rest out. Movement and strengthening exercises improve the quality of your tendons, ligaments, and joints. If you get stiff and sore from sitting and staring at a screen for hours — and who doesn't — then getting up every 25 to 30 minutes is a good idea. If you pair that with another healthy habit like drinking water, you'll move forward even faster.

E — Establish New Patterns with the Lean Mindset Method

It's not just your body that needs to move. If you want lasting fat loss, your mindset has to change, too. That's why E stands for Establish New Patterns. This is what makes the biggest difference for long-term success.

To lose fat and keep it off, you need to let go of your old way of thinking: carbs are bad, fat is bad, a tiny bit of junk food is going to make me lose all my progress, I'm too old, I'm not athletic, I have to be perfect to succeed with fat loss. Reframe your thinking with what I call the Lean Mindset Method, based on CBT — cognitive behavioral therapy.

Here's how it works: first, you identify your thinking traps — automatic thoughts that come and go without intention. Things you say to yourself repeatedly that don't get you to your goals or make you feel bad about yourself. For example:

  • "I ate a cookie so my whole diet is ruined. I might as well eat whatever I want tomorrow." — One treat won't undo all your progress. Let go of any guilt you're feeling. It doesn't help.
  • "I missed one workout this week. I'm going to lose my muscle and start gaining fat." — Missing one workout is not going to undo your progress. Muscle growth and fat loss is a long-term process.

Most of my clients have struggled with that all-or-nothing mindset and have been on that fat loss roller coaster dozens of times. They're successful, driven people who expect a lot from themselves, and they beat themselves up — often very hard — about every little slip. And that only makes things worse. So instead of thinking "I've ruined my diet, I might as well just give up," you say to yourself: "I ate a bit more than I planned, but it's also just one meal, and I can move on with the next meal."

Until you change the way you talk to yourself and the habits that have been ingrained for years — maybe decades — you'll keep fighting with those last 10, 20, 30, or 40 lbs over and over again. I did.

So why not just eat clean or eat real food, like we keep getting told? Because avoiding the foods you love isn't sustainable. Sure, you probably need to eat fewer ultra-processed foods than you currently do, and in smaller amounts and less often. But trying to ban them altogether isn't going to work long-term. That's why many fitness competitors and bodybuilders often gain a lot of weight when they're not competing — after being deprived for months, they can't control themselves around those treat foods. I did that myself throughout my 20s.

When I finally decided that all foods could be part of my plan, it actually took away a lot of those cravings. Before, I could never have any chocolate or ice cream in the house because I would eat it all and then go to the store to buy more. But now my kitchen has lots of sweet treats — chocolate on the shelves and usually ice cream in the freezer — and I can leave it for long periods or just have one serving and put the rest away, which totally blows my mind whenever I think about it. I'd like you to get to that point, too.

R — Recover Sufficiently

Real progress isn't about restriction or pushing harder all the time. It's about creating balance — and that includes getting enough rest. The final step of the POWER Framework is to Recover Sufficiently. If you're not recovering properly, you're not building muscle, burning fat, or performing at your best. Muscle grows when you're resting, not when you're actually training it. And if you're tired, you probably prefer plunking down on the couch with some takeout food over preparing a healthy meal.

After 40, our ability to recover from exercise might go down slightly — but I don't think this is as big a deal as many people say.

I think it's mainly that a lot of people in their 40s and 50s are overworked in so many ways. If you're managing everything else in your life well, you could probably be doing six days a week of workouts and still be fine. Rather than worrying so much about exercising too much, we need to worry about not exercising enough. Less than a quarter of people are meeting the really quite easy health guidelines — 2 days of resistance training a week and 150 minutes of cardio.

Why Sleep Is a Fat Loss Tool

Now, the problem is that our sleep quality can go down because our production of melatonin is reduced — that's the hormone that manages our sleep-wake cycle. Sleep can get more fragmented, with lighter sleep and sometimes early waking. Not only that, but the decline in sex hormones as we age affects our sleep too. The reduction in testosterone levels in men is slight and gradual, but fluctuating levels of estrogen and progesterone in women can really impact sleep.

So, why does sleep matter for fat loss?

When you don't sleep enough, your body increases ghrelin, your hunger hormone, and decreases leptin, your fullness hormone. So you'll have everything against you when it comes to fat loss. Try to get at least seven hours a night and give yourself a solid sleep routine. Start winding down 30 to 60 minutes before bed. Dim the lights and turn off screens. If you're working on your laptop or scrolling on your phone until your head hits the pillow, your melatonin release — which already gets lower with age — is going to be further reduced. You may fall asleep, but you won't sleep as well. When you go to sleep, you want that room to be quiet, cool, and as dark as you can possibly get it.

Rest and recovery helps make fat loss sustainable. And it's particularly important if you want to build lean muscle over 40.
