Why You Can't Stick with Healthy Habits in Midlife & How the 80/20 Method Helps with Real Change

If there is one thing I have learned in working with hundreds of women in midlife, it is this:

Most of us already know, for the most part, what we should be doing to support our health. We know we feel better when we eat more nourishing meals, move our bodies more consistently, get to bed earlier, drink more water and cut back on the habits that leave us feeling worse. And yet, when it comes to midlife health and lifestyle change, the real question is usually not: What should I do?

The real question is:

Why is it so hard to actually do it and stick with it?

I understand this deeply from my own life. I can remember a time when trying to change my healthy habits in midlife (before I understood the 80/20 method) every Monday felt like New Year’s Eve. I would slip into habits over the weekend that didn’t feel aligned, followed by that familiar cycle of guilt and shame, and then resolve to completely reset. This was going to be the week.

I would create a grand plan: salads every day, a new exercise routine, maybe supplements that matched the version of myself I was trying to become. Everything would start on Monday. And for a moment, it felt convincing. But the pattern always stayed the same.

The changes lived mostly in my head. The intention was there. The desire was real. But the follow-through did not last.

And over time, I began to see this same pattern in so many women navigating midlife. They reach out because they genuinely want change. Their intentions are sincere. They are ready. But when it comes to building consistent, sustainable habits, that is where the real challenge begins. That is why understanding why change feels so hard in midlife matters so much.

A concept that has truly transformed my life came through the Pareto Principle, often known as the 80/20 principle : a way of understanding that a small number of actions tend to create the greatest results.

In his book The Golden Life, Michael MacIntosh introduces a powerful framework that helped me see this clearly and apply it in a powerful, practical way.

Healthy Habits in Midlife: Why the 80/20 Method Changes Everything

This is where a powerful mindset shift begins.

The Pareto Principle, often referred to as the 80/20 rule, was first observed by economist Vilfredo Pareto, who noticed that 80% of the land in Italy was owned by just 20% of the population. Over time, Pareto saw this same repeating pattern everywhere. Some examples of how it applies: in business, it is often said that 80% of sales come from just 20% of products. In a garden, 80% of harvest will come from 20% of plants. In the music industry 20% of music is played 80% of the time.

And in your own life, around 80% of your results tend to come from just 20% of your daily actions. The number can vary but the concept is the same. When you understand this, you understand that not everything we do carries equal weight. When it comes to change, you need to focus on what actually drives the most significant results. The key is finding your 20%.

This is where I now see change differently through what Michael calls: The Mud, The Gold & The Diamond.

Let's Explore.

The Mud: The Habits That Keep Us Stuck in Midlife

This is where we begin—with awareness. The mud is the 80% of daily actions that does not get results. These are the habits and patterns that keep us feeling stuck, depleted or out of alignment.

In midlife nutrition & lifestyle, the mud might look like:

• mindless nighttime eating or grazing

• relying on convenience or ultra-processed foods

• skipping meals during the day, then overeating later

• sitting for long periods with little movement

• staying up too late

• scrolling on social media for hours at a time

  
  

When you spend most of your time in the mud, it becomes difficult to create the meaningful change you want.

The Gold: The Habits That Begin to Move You Forward

The gold is the 20% of habits that create real momentum. These are not extreme changes. They are the simple, foundational habits your body responds to—especially in midlife.

In midlife nutrition and lifestyle, the gold might look like:

• prioritizing protein at meals

• including more whole foods like vegetables and fruit

• eating regularly instead of skipping meals

• drinking enough water

• getting to bed earlier

• moving your body in simple, consistent ways

  
  

These habits may seem basic, but they are powerful. This is where small changes begin to add up.

The gold is not about doing everything perfectly. It is about consistently doing what works.

The Diamond: Where Real Change Happens

This is where the 80/20 principle goes even deeper. Because even within the gold, there is a smaller set of habits that create the greatest impact. This is the diamond.

The diamond is the highest-leverage 1%—the one or two daily habits that create the most meaningful change in your health. It is the 20% within the 20%.The few things that give you more benefit than anything else.

The diamond is different for everyone. Finding your diamond is not always obvious. It requires a shift in how you think and learning to see your habits through the lens of what actually creates meaningful change towards what you want to achieve.

You get clear on your mud. You build your gold. And you commit to your diamond.

How to Begin: Applying The Mud, The Gold & The Diamond in Real Life

This is where it becomes real. Micheal refers to this as results-based thinking. Understanding the mud, the gold, and the diamond is one thing. Applying it is where change happens. The way I use this in my own life is simple.

I stay aware of my mud, focus on my gold, and commit to a small number of diamond results-based habits each day.

Right now, I have two daily anchors and one weekly anchor that I commit to for 90 days. I’m not trying to change everything at once or fall back into that cycle of guilt and overwhelm. Instead, I take it one step at a time. At the end of 90 days, I reassess and adjust.

If you are curious, my current diamonds are a daily walk, a daily meditation and writing one article each week as I build my Midlife Restoration Method. Simple practices that keep me energized, mentally clear and connected to my work. To support consistency, I keep it visual. I use a calendar and simple stickers, and each day I complete my diamond habits, I give myself a gold star. There’s something powerful about seeing that streak build and it keeps me going.

And this approach is something I now use to help others.

My daughter recently shared that she wanted to get healthier. As a college student, her first meal was often late in the afternoon and usually fast food. We started by identifying her mud - things like long hours on TikTok- and then narrowed it down to her diamond.

Just two daily anchors: protein before noon and a 20-minute walk. That’s it.

Because it felt simple and doable, she committed to it. And within just a couple of weeks, she already noticed a big difference. In 90 days, we’ll reassess and build from there, one step at a time.

Because this is what works. It’s not about doing more. It’s about choosing what matters and staying with it.

How to Bring the Diamond into Your Life

If you’re ready to apply this in your own life, start here:

Step 1. Make a list of your mud: the habits that are keeping you stuck. Work to remove the mud from your life.

Step 2. Make a list of your gold: the core habits that support what you want to achieve. Don't filter, just write them out.

Step 3. From your gold list, identify 1 to 3 diamond actions you can commit to daily. Make them simple and realistic. The actions you can commit to for the next 90 days

Step 4. Write them out as simple intentions. Like "have 25 grams of protein every meal" or "walk 20 minutes a day". Put them where you will see them every day.

Step 5. Bonus: get a planner & stickers. Track them in a planner or calendar—and each day you follow through, give yourself a gold star.

Keep it simple. Stay consistent. Build the streak. This is how change happens.

Not all at once.Not through trying to completely change your entire life every Monday. But through small, intentional actions repeated daily.
