Break through the plateau and start seeing real change

Most people are aware that weight loss requires them to burn more calories than they eat. However, there are many factors that play into weight loss, including lifestyle habits, hormonal changes and environmental factors. In this article, we’ll explore how you can use your metabolism to break through your weight loss plateau and provide tips for implementing the macro diet effectively.

The New Year’s resolution hype has faded away, and you’ve made a commitment to get in better shape this year. But somehow, your weight loss progress suddenly hit a plateau, despite sticking to your diet and exercise plan. And now you find yourself frustrated even though you have tried everything to shed off the last stubborn pounds.

Truth is, you are not alone. It's a really common problem many people face when they are trying to lose weight. They experience a slowdown in their progress which can be extremely unmotivating, but without realistic goals around following the right diet and exercise plan, according to this research paper the maintenance of lost weight can be even more challenging (1).

However, the good news is that there are ways to overcome this plateau by incorporating a macro diet into your daily routine. Not only will this diet boost your metabolism, but it will give you the jumpstart you need to reach your weight loss goals.

But first, it's recommended to understand how your metabolism plays this vital role in weight loss. You can take this metabolism quiz to assess your current metabolic health.

What is a weight loss plateau and why does it happen?

A weight loss plateau is when your weight progress begins to slow down or even abruptly stops even though you are following a healthy diet plan and getting the same level of activity.

What tends to happen at the beginning of your weight loss journey is you begin shedding off pounds rapidly, but as your body adjusts to your diet and routine, you see a decline in your progression. This can happen based on various factors such as lifestyle changes, stress, or sleep, but ultimately the biggest factor is your metabolic health.

"A plateau is an important and natural part of any weight loss. During a plateau, your body is adjusting to your new weight after the recent weight loss. This happens before you are able to lose more weight."
Danielle Cadosh, Nutritionist at Lumen

Once you understand the significance your metabolism plays in weight loss, you can begin to make the necessary changes to optimize your metabolism and integrate a personalized macro diet plan that fits your physiology.

This sets you up for smoother sailing to optimize your metabolic flexibility. Integrating a personalized plan is a proven and sustainable way to boost your body and put it back into fat-burning mode.

The two basic ways to do this are by monitoring your metabolism and implementing the right foods.

How can you become metabolically flexible?

Metabolic flexibility refers to the body's capacity to shift between various fuel sources, such as carbohydrates and fats, depending on availability. Being metabolically flexible allows for easy transitioning between burning carbs for energy during intense workouts and burning fat for energy while at rest. This ability is critical for effective weight management as it enables the body to burn fat efficiently, even when not engaged in physical activity.

The good news is that metabolic flexibility is a range, and we can move along that range. If we find that we are metabolically inflexible, there's an opportunity for us to turn things around and achieve our goals. We just need to take action and form the right habits in the four lifestyle domains: nutrition, movement, sleep and mind to improve metabolic flexibility.

How to Beat Your Weight Loss Plateau with Your Metabolism

Now that you understand the function and significance of your metabolism, let’s look at some ways that you can beat your weight loss plateau. You’ll need to monitor your metabolism and create a diet plan that boosts it.

When you consume fewer calories than your body needs to maintain its current weight, your body responds by slowing down your metabolism to conserve energy. In response to a calorie deficit, your body burns fewer calories to try conserve energy.

This metabolic slowdown can lead to a plateau in weight loss, where your body burns fewer calories than before. This makes it harder to create a calorie deficit and lose weight. This is why many people who follow calorie-restriction diets experience plateaus, despite their best efforts to maintain a calorie deficit.

Strategies for optimizing your metabolism to beat weight loss plateau

Nutrition and exercise go hand in hand and are the two main factors that will help you beat your weight loss plateau. Our Lumen nutritionists also suggest that you integrate foods that boost your metabolism and develop a more personalized nutrition and exercise plan.

A plateau may occur when you have lost all of the weight you are going to lose through your current exercise and diet program. Ask yourself whether you're satisfied with your current weight or if you want to lose more. If your answer is the latter and you want to lose more weight, you'll need to adjust your weight-loss program and reassess your habits.

Intermittent fast has also been proven as a tactic to shed pounds. By determining your optimal fasting schedule, you can measure when your body enters into fat burn or carb burn. Intermittent fasting hours for women and men may differ depending on their metabolic state and physiology - which makes measuring your metabolic state helpful.  

Track what you eat

Sometimes you might feel you're not eating a lot, yet you still can't seem to lose weight. Research (2) has found that people do tend to have a tendency to underestimate and overestimate the amount of food they eat. Logging your food on an app will help you to effectively track your intake.

Measuring whether your body is burning carbs or fats will take out the guesswork and allow you to assess whether you're on track and meeting your recommendations. These insights will guide you to making better choices and sticking to healthy habits on your way to metabolic health.

Make yourself accountable for your new habits, for example, by meal planning and prepping your food in advance for the week, so you are less likely to make unhealthy choices or eat out when you're short on time or feeling tired.

Hacking your metabolism with Dr Jason Fung

"Knowing whether your body is burning fat or burning carbs is a process called biofeedback. If you don't know if you're doing things right or wrong, you're never going to improve."
Dr Jason Fung, MD

'Understanding what your body is doing, what fuel it is using, and if it's the right fuel for you to lose weight - is process of biohacking', adds Dr Fung.

Incorporate exercise into your routine

Rev up your workouts as soon as you start getting comfortable during your exercise. If you get to a point with your exercise routine where you’re not breaking a sweat or feeling that exertion, that might mean your body is used to the exercise, and you’re not burning calories at the same rate.

If you're running out of energy too soon, a nutritious snack like a banana before exercising might be the best pre workout meal to supercharge your performance.

An increase in lean muscle mass also has a positive impact on improving metabolism (3). Complementary to what you're eating, track your movement throughout the day and how often you're exercising.

Since your old workout plan might not be working for you, we have compiled a few alternatives you can try instead.

Lumen metabolic coaches recommend:

  • A high-interval training that involves short bursts of high-intensity exercise
  • Circuit training including integrating a combination of resistance and cardiovascular exercise
  • Resistance and strength training such as lifting weights and dumbbells
  • Endurance and aerobic exercise including walking, jogging, and cycling
  • Increase your NEAT by setting a daily step target, setting alarms to get up hourly and walk down the hall or take the stairs, and walking after meals. Every movement counts. 

Make yourself accountable for your new habits, for example, by setting a specific goal such as running a 5k or doing 10 push-ups every day, and then tracking or sharing your progress on an app or with a friend to stay motivated and committed.

"I think that anybody can do this… if I can do it after four years of not losing weight, only gaining weight - then finding Lumen and losing 42 pounds. I am just amazed at what my body has been capable of doing."
Stephanie, 42, Ohio

Strive for high-quality sleep

Sleep is underrated, but, in fact, it is a critical factor in weight loss. A lack of sleep can stall your weight loss in a number of ways. Too little sleep can cause spikes in your cortisol levels, the stress hormone. This might lead you to eat more than you might otherwise, feel fatigues and experience digestive issues. Getting 7-9 hours of quality sleep can help your body shift to fat burn overnight - which is a great indicator for a faster-working metabolism. 

Make yourself accountable by getting into a healthy sleep routine, avoiding screens before bed and finish eating dinner at least 2-3 hours before bedtime. 

Top tips from our Lumen experts:

  • Set realistic goals is the most important factor for success in achieving your weight loss resolution.
  • Time your meals to promote healthy eating habits. For example, finish your meal 2-3 hours before bedtime. 
  • Get adequate and high-quality sleep of at least 7-9 hours every night. 
  • Rev up your workouts. Try resistance training to protect and build muscle tissue or aerobic activity. 
  • Manage your stress to prevent emotional eating and high-carb snacking. Try meditation, deep breathing, journaling, or fun hobbies. 

Foods that boost your metabolism

Your diet is one of the leading factors that will boost your metabolism. Having a well-balanced diet with a variety of high-density foods is a great way to help boost your metabolism.

Beat your plateau with a macro diet 

Macronutrient-based diets, such as low-carb diets, could help avoid the challenge of a plateau by promoting metabolic flexibility. For example, when we restrict carbohydrates, our bodies are forced to use other sources of fuel, such as fat. A decrease in insulin levels, caused by carb restriction, makes our bodies more likely to burn fat as fuel, resulting in a shift in fuel usage - an important aspect of metabolic flexibility.

This approach allows your body to burn more calories even when you're not constantly in a calorie deficit - a key in helping prevent plateaus in weight loss. When we are metabolically flexible, our bodies will use the fat in our bodies for energy on days when we are in a caloric deficit, enabling us to lose weight. Additionally, by promoting metabolic flexibility, macro-based diets may have other health benefits, such as improved insulin sensitivity and reduced inflammation.

"I think the difference with Lumen is that slow and steady wins the race. It’s about being intentional. It’s not about being ridiculously restrictive."
Julz, lost 10 pounds in 3 months

A macro diet is all about balancing your intake of macronutrients, which include protein, carbohydrates, and fats. By tracking the amount of each macronutrient you consume, at the right time, you can ensure that you're fueling your body properly for your fitness goals.

For example, if you're trying to build muscle, you'll need to increase your protein intake to support muscle growth. On the other hand, if you're trying to lose weight, you may need to reduce your carbohydrate intake. By following a personalized nutrition plan with your macros, you can adjust your diet to suit your goals and break through your plateau. So if you're stuck in a fitness rut, consider giving a macro diet a try.

״A macro-based diet allows each of us to harness the power and potential of our metabolism in our journey to our health goals. Cycling through low and medium daily carb intake promotes better metabolic flexibility, allowing our body to shift between carb and fat use for energy easily."
