My Intermittent Fasting Weight Loss Journey After 40

I have been intermittent fasting for over two years now. After reaching my goal weight a year ago, I started experimenting to find a way to fast that would give me all the benefits without losing more weight. That’s where I am at now. I wanted to share my intermittent fasting weight loss journey with you to encourage you on your own journey. This article will include some before-after pictures, practical tips that made a world of difference for me, and some ideas you can try if you are struggling to achieve the results you want.

My Intermittent Fasting Weight Loss Journey

My intermittent fasting weight loss journey actually started in my thirties after having my sixth baby. I really wanted to lose the extra weight that was getting harder and harder to lose and nothing seemed to work. I tried all the reset-your-metabolism books and all the diets under the sun, including intermittent fasting. It didn’t matter! I was a slave to my food cravings and could not stick to anything.

How It All Started

Then, in my forties, things got really out of control and I was gaining weight even though I was eating the same way and sustaining the same level of activity. I decided that it was it, I needed to take charge of my health.

That’s how it all started. The moment something clicked in my mind and I said enough is enough. I think many of us women who can’t lose weight know intuitively that something’s not quite right with our bodies. That’s why books about “resetting your metabolism” and “healing your hormones” are so popular. For me, what changed everything was the combination of deciding I was going to make it work and doing a 5-day modified fast.

No matter what your goal is in life, you have to want it bad enough. Otherwise, you make excuses.

Modified Fasting

Modified fasting is a doable prolonged fast. Do you know about the benefits of fasting? Fasting is a way to heal your body through a process called autophagy. As it runs out of energy, it starts eating itself. That may sound a bit scary, but don’t worry, it is a good thing. It eats damaged and redundant cells and will replace them with new ones. The deeper healing happens after about 3 days, and 5 days is even better.

The problem is, the average person will not be able to last on a water fast for more than 2 days. That’s where modified fasting comes in. You get to eat just enough food to continue on and yet, still benefit from this deep healing

How It Went

My first modified fast was the stepping stone that enabled me to start healing and trusting my body. If you read Modified Fasting: How You Can Benefit From Fasting Without Starving, you will learn that fasting helps improve your insulin sensitivity. Once you do that, you will notice that you have less bloating and belly fat and that you gain freedom over food cravings.

How Long Did It Take to Lose 30 lbs?

After my first modified fast, I started looking into intermittent fasting again. When I tried intermittent fasting in my thirties, I did the 16:8 method. This time around, I decided to try longer fasts. Here are some methods that I found helpful:

I tend to favor longer fasts because they enable you to get into a deeper ketosis and increase your metabolic flexibility (more on that later).

Now, to answer the question How long did it take to lose 30 lbs? it took 2 years! For the first few months, I didn’t really know what I was doing, and not losing much weight. As I became more consistent with my intermittent fasting window, I started losing about 2 lbs a month. Then, after a year, I relaxed my intermittent fasting approach because I had reached my goal weight (and lost 20 lbs). Over the course of the next year, I still lost about 10 lbs even though I was no longer trying to lose weight.

How It’s Going

So, that’s how it’s going. I went from feeling like I could hardly stop gaining weight to wondering how to stop losing weight. Now, it’s time to figure out how to make sure I eat enough on my nonfasting days to maintain my weight. I am mostly just listening to my body at this point and doing only one 24-hour fast a week to maintain good sleep, my metabolic flexibility, and my overall energy level. If the need arises to start tracking my food on nonfasting days to ensure I eat more, I will include resources for this purpose in my 30-Intermittent Fasting Transformation.

Create Your Own Intermittent Fasting Weight Loss Journey

To get your own successful intermittent fasting weight loss journey, I recommend you follow the following 5 steps (which are at the core of my Fasting Program):

  • Get started to maximize your success: Learn to track your progress and set realistic expectations.
  • Kickstart your weight loss: Improve your insulin sensitivity with one modified fast or a 7-day Keto Cycle.
  • Become metabolically flexible with intermittent fasting: Teach your body to get in and out of ketosis.
  • Exercise and tone up: Muscle mass burns more energy. Plus, it helps maintain your health and youthfulness.
  • Maintain your weight loss and stop losing weight: After reaching your goal weight, you define how best you can include intermittent fasting to suit your lifestyle.

This formula is your key to success.

Practical Tips for Success

I do have some practical tips you can try right now if want to get started and achieve the results you have been wanting:

  • Go all in: You have to decide that you really want it. Intermittent fasting is not hard. In fact, it is super easy. No macro counting, no calorie restriction, and no special diets. You still have to stick with it if you want to see results though.
  • Start with a short reset: A 5-day modified fast or a 7-day keto cycle will speed up your progress and give you extra motivation.
  • Pick a fasting window that is long enough to sustain optimal ketosis for a few hours.
  • Enjoy some nonfasting days: It will keep your metabolism guessing and the process fun.
  • Workout but not too much: You don’t want to add too much stress to your new lifestyle. Find workouts that you enjoy and yield results. You may enjoy reading Starting Yoga at 40 or Later: Everything You Need to Know.

I truly wish I had known all this years ago. Now, that you do, You can lose weight with intermittent fasting even after 40.

Metabolic Flexibility

I mentioned the importance of metabolic flexibility already, Metabolic flexibility means that your body is able to switch back and forth from using glucose to ketones for energy.

You will need to make sure your fasting window is long enough to sustain optimal weight loss ketosis for at least 2-3 hours. Technically, you are in ketosis when your ketone reading is above 0.5 mmol/L, but you will most likely notice the signs of ketosis when you are in optimal weight loss ketosis, which is around 1 mmol\L.

Signs of Ketosis

Here’s what you will notice:

  • Your hunger won’t bother you as much.
  • You will feel energetic and focused.

These telltale signs mean that you have experienced the metabolic switchover. Read my post How to Start Intermittent Fasting for Weight Loss to learn more.

What If Intermittent Fasting Isn’t Working?

In my 30-Day Intermittent Fasting Transformation, you will find a whole section to troubleshoot when intermittent fasting isn’t working. Here, I will simply share the two most common reasons:

  • You aren’t staying in optimal weight loss ketosis long enough: Try a ketone monitor to test your ketones.
  • You’re not filling up on nutrient-dense foods that nourish your body: Tweak your diet to figure out what works.

It is also very common for women to think something isn’t working when the truth is, they have unrealistic expectations. Weight loss with intermittent fasting should be slow and steady. Plus, it is perfectly normal to not lose any weight one month. Weight loss is not a straight line going down consistently at the same rate. Instead, it looks like a wavy line, with ups and downs.

In Summary

My intermittent fasting weight loss journey was slow and steady. It was rewarding and it taught me how fasting has the potential to change women’s lives. That’s why helping others do the same has become my passion! Now, your turn!
