It’s a familiar story for us ladies on a weight loss journey. The first few weeks bring exciting progress – the numbers on the scale decrease, clothes begin to fit more comfortably, and our energy levels get better. Then suddenly, despite keeping the same diet and exercise routine, our progress halts. The scale refuses to budge for days, then weeks. Welcome to the weight loss plateau – a frustrating but entirely normal part of the weight loss process.
So, What Exactly Is a Weight Loss Plateau?
In short, it’s when you’re ‘being good‘ or ‘on it‘ but not seeing good changes as a result. A weight loss plateau occurs when your body has adapted to your current diet and exercise programme, and you stop losing weight despite keeping up the same habits that were helping you shed pounds before. Typically, plateaus happen after you’ve been losing weight consistently for a while – often after losing about 10% of your starting weight.
This is by no means a sign of failure; rather, it’s your body’s natural response to weight loss. Understanding why plateaus happen is the first step to getting through them.
The Science Behind Plateaus: Why Our Bodies Resist Further Weight Loss
Energy Balance: The Foundation of Weight Change
At its most basic level, weight loss operates on the principle of energy balance – the relationship between the calories you consume (eat) and the calories you expend (‘burn’ through movement). To lose weight, you need to create a calorie deficit – this is where you consume (eat) fewer calories than your body uses for activity.
Calories In < Calories Out = Deficit
However, this seemingly simple equation becomes more complex as your weight loss journey progresses.
Your Shrinking Metabolism
One of the most crucial concepts to understand is that your calorie needs decrease as you lose weight. This isn’t a flaw in your body’s design; it’s simple physics. A smaller body requires less energy to function than a larger one. This is one of the most overlooked facts when someone is trying to lose weight.
Think of it this way: carrying a 5-stone rucksack whilst walking requires significantly more effort than walking without it. When you lose weight, it’s like putting down that rucksack – your body now needs fewer calories for everyday functions because it’s carrying less mass.
For example, a woman weighing 80kg might initially need about 2,000 calories daily to maintain her weight and 1,500 to lose weight. After losing 10kg, her body might only require around 1,800 calories for maintenance at her new 70kg weight. If she continues eating 1,500 calories (which initially created a 500-calorie deficit), her deficit has shrunk to just 300 calories – slowing her weight loss significantly.
Metabolic Adaptation Goes Beyond Size
Your body also undergoes metabolic adaptations beyond what can be explained by size alone. When you consistently consume fewer calories, your body becomes more efficient, learning to function on less energy – a survival mechanism from our evolutionary past.
Studies show that people who have lost significant weight often burn 5-15% fewer calories than would be predicted based on their body size alone. This is your body’s way of conserving energy when it perceives potential food scarcity.
This presents itself by us being less active, whether we choose the lift more than the stairs or park closer to the supermarket entrance – we even fidget less! These are all subconscious ways our body preserves energy, without us even realising it’s happening.
Muscle Loss Compounds the Problem
Without proper resistance training (training with weights) and adequate protein consumption during weight loss, some of the weight you lose will be muscle tissue. Since muscle burns more calories at rest than fat does, losing muscle further reduces your daily calorie expenditure, making continued weight loss more challenging.
Signs You’ve Hit a Plateau
How do you know if you’ve genuinely hit a plateau? Consider these indicators:
- Your weight hasn’t changed for at least 3-4 weeks despite maintaining your diet and exercise routine
- Your measurements (waist, hips, etc.) have also remained static
- You’ve been losing weight consistently before this stall
- You haven’t made any significant changes to your eating or activity patterns
Breaking Through: Evidence-Based Strategies to Overcome Plateaus
Now for the encouraging news – plateaus can be broken with the right approach. Here are proven strategies to get the scale moving again:
1. Recalculate Your Calorie Needs
The calorie deficit that worked for you at the beginning of your journey is likely no longer sufficient. Use an online calculator to estimate your current maintenance calories based on your new weight, then aim to create a moderate deficit of 15-20% below that figure.
Be careful not to reduce calories too drastically – extremely low-calorie diets can further slow your metabolism and lead to nutrient deficiencies. I do not not advise going below 1,200 calories without medical supervision and your requirement depends on your weight, height and activity levels.
2. Prioritise Protein
Increasing your protein intake serves multiple purposes when trying to overcome a plateau:
– Protein has a higher thermic effect than carbohydrates or fats, meaning your body burns more calories digesting it.
– Adequate protein helps preserve muscle mass during weight loss, keeping your metabolism higher.
– Protein increases satiety, helping you feel fuller despite eating fewer calories.
Aim for 1.6-2.2 grams of protein per kilogram of your current body weight, spread throughout the day. You can find out how much protein is in your food from the packaging or by checking online resources (Google it!)
70kg x 1.6g = 112g protein
3. Revamp Your Exercise Strategy
Your body becomes more efficient at exercises you perform regularly, gradually burning fewer calories during familiar workouts – basically it knows what to do and gets comfortable doing it. To combat this:
– Add high-intensity interval training (HIIT) to increase calorie burn and metabolic rate.
– Incorporate new forms of cardio your body isn’t accustomed to.
– Most importantly, focus on progressive resistance training (weight lifting). Building muscle is one of the most effective ways to boost your metabolism long-term.
4. Mind the Little Movements
Non-exercise activity thermogenesis (NEAT) – the energy expended for everything that isn’t sleeping, eating, or formal exercise – can vary by up to 2,000 calories between individuals. Increasing your daily movement outside of structured workouts can significantly impact your calorie expenditure:
- Take regular standing and walking breaks if you work at a desk
- Choose stairs over lifts
- Park farther from entrances
- Consider a standing desk
- Take phone calls whilst walking
These small changes add up substantially over time.
5. Reassess Your Tracking Methods
Research consistently shows that most people underestimate their calorie intake by 20-30% unintentionally. Common culprits of missed calories include:
Forgetting to count cooking oils, sauces, and dressings
Using inaccurate portion estimates rather than weighing foods
Weekend eating that differs significantly from weekday patterns (cheat meals and cheat days are a big no-no!)
Mindless snacking or tasting whilst cooking or late at night
Try weighing and measuring everything you eat for two weeks to identify potential hidden calories.
6. Consider Diet Breaks and Calorie Cycling
Emerging research suggests that taking planned breaks from your calorie deficit can help overcome plateaus by temporarily boosting hormones like leptin that regulate hunger and metabolism.
Try eating at maintenance calories (not overeating) for 1-2 weeks before returning to your deficit, or implement calorie cycling by having higher calorie days (still at or below maintenance) interspersed with lower calorie days.
7. Manage Stress and Prioritise Sleep
Both chronic stress and inadequate sleep can sabotage weight loss efforts by:
- Increasing cortisol, which promotes fat storage, particularly around the abdomen
- Disrupting hunger hormones, increasing appetite and cravings
- Reducing energy for physical activity
- Impairing recovery from workouts
Aim for 7-9 hours of quality sleep and incorporate stress management techniques like meditation, yoga, or simply scheduling regular downtime.
When Plateaus Serve a Purpose
Sometimes, a plateau isn’t something to push through immediately. If you’ve been in a significant calorie deficit for months, your body might benefit from a maintenance phase – where you stay where you are in terms of weight, diet and workouts – before continuing weight loss efforts. During this time:
- Your metabolism can partially recover
- Hunger hormones can normalise
- You can focus on building healthy habits that will sustain your results
- You’ll likely experience psychological relief from diet fatigue
Consider maintaining your current weight for 1-3 months before attempting further weight loss if you’ve already lost a significant amount of weight or have been dieting for an extended period.
The Psychological Side of Plateaus
The mental challenge of plateaus often exceeds the physical one. When progress stalls, it’s easy to feel discouraged, question your methods, or even abandon your goals entirely.
Remember that weight loss is not linear. Progress often comes in bursts followed by periods of stability. This pattern is completely normal and doesn’t indicate failure. I experienced highs and lows all throughout my weight loss.
Try shifting your focus temporarily from the scale to performance-based goals: increasing your strength, improving your endurance, or mastering new skills. These victories can sustain motivation whilst your body adjusts.
Conclusion: Patience and Persistence Pay Off
Weight loss plateaus are not permanent barriers, but rather a predictable phase in your journey. They signal that your body is adapting – a sign that your previous efforts have been effective enough to change your physiology.
By understanding the science behind plateaus, you can handled them with logic and patience, rather than frustration. Adjust your approach, be patient with the process, and remember that consistent small efforts over time lead to truly remarkable results.
Your body is always responding to what you’re doing – even when the scale doesn’t immediately reflect it. Trust the process, make evidence-based adjustments, and you’ll find yourself moving in the right direction once again.
