Unrealistic expectations promoted by magazines and social media just make it worse. So, why does it take so long to lose weight? Despite all of the pressure we get from society to lose weight in the blink of an eye, gradual weight loss is the healthiest and plateaus are completely normal. Here we’ll discuss why it takes so long to lose weight, plus give you some strategies to overcome common barriers.

4 Reasons Why Losing Weight Takes Time

So, why does it take so long to lose weight? It all comes down to biology.

When you (or your doctor) decide that you should drop a few pounds, you can immediately choose to restrict calories or hit the gym, but it takes a little longer for your body to start changing. Since our bodies are built to survive, the standard operating procedure is to hold onto fat as energy stores. This makes it very hard to lose a dramatic amount of weight in a short period of time – and even harder to keep it off! Here’s a little explanation of some common reasons why it takes so long to lose weight.

1) The body holds onto fat

It’s a frustrating reality for dieters and figure-conscious people everywhere: our bodies naturally retain fat as energy.

Thousands of years ago, this was a critical ability to ensure survival. When you’re not sure when you’ll eat again, and extended famine is the norm, the ability to store fat as extra energy ensures health even when food stores are low. However, in modern life, excess food supply – as opposed to famine – tends to present the more pressing issue. Our bodies still cling to fat as a survival tactic, but our current, calorie-rich environment makes this quality more of a hazard than a benefit. As of last year, the over a third of American adults are obese and another third fall into the overweight category.

So, why does weight loss take so long? Since our bodies are hard-wired to retain fat, biology fights our conscious attempts to eliminate extra fat. As you start to eat less and move more, you begin drawing on this stored fat for energy. If you continue burning more calories than you consume, this will eventually lead to weight loss. However, your body doesn’t want to eliminate its prized, saved-up energy. As a result, we don’t shed fat as quickly as we may like and it’s absolutely normal to plateau.

Set Point Theory

This phenomenon of fat retention is sometimes discussed in connection with the set point theory.

Many experts propose that each person maintains an individual “set point” for weight, at which their body most likes to exist. While it proves relatively easy to gain or lose about 10-20 pounds (4-9kg), our bodies undergo biological changes when we venture outside that pre-set range. When weight decreases dramatically, metabolism slows, hunger increases and some people experience emotional changes to slow weight loss. This is why many people reach a point where they feel like they just can’t lose any more weight. Thankfully, it may be possible to “reset” your set point over time.

How to Lose Weight Faster

Don’t go to extremes with weight loss.

When you eat fewer than 1200 calories per day (or 1500 if you’re a man) you risk triggering a starvation response in your body. If your body interprets a lack of caloric resources, it doubles-down on its efforts to retain fat stores. This is the exact opposite of what you want when you’re trying so hard to lose weight. Over-exercising can also have the same effect. So, to keep your body feeling secure and maximize sustainable weight loss, avoid going to extremes on phentermine.

Unless otherwise instructed by your doctor, aim for a daily calorie deficit of about 500-1000 calories to lose a steady 1-2 pounds per week. For a moderately-active woman that burns around 1800 calories per day, this would mean a goal of 1200-1300 calories per day. You can healthfully achieve this deficit through eating a portion-controlled diet and exercising most days, both of which are great habits to sustain over the long term!

Another factor that gets in the way of rapid, prolonged weight loss is natural metabolism slowdown. It takes more energy to power a bigger machine, so as you shrink so do your energy needs.

Fat tissue and muscle tissue both burn energy, so when you lose pounds of fat and muscle your daily energy needs decrease. We often describe this effect as a metabolism slowdown. Why does this make weight loss take so long? Since your smaller self doesn’t need as much energy to power daily activities, it’s important to regularly reassess energy (and macronutrient) requirements. If you don’t adjust your diet and activity goals as you lose weight, the process is slower because the calorie deficit you’re creating decreases over time. Thankfully, many weight loss apps automatically (and constantly) adjust estimated needs based on your current weight and objectives!

While the main goal is to shed extra fat, muscle mass decreases as well during weight loss. Since muscle is more metabolically active than fat, losing muscle mass more dramatically affects daily energy needs more than losing pure fat. Unfortunately, it’s not possible to target weight loss so that you only lose fat. You can, however, modify your diet and exercises to promote muscle maintenance and building.

How to Lose Weight Faster

To minimize plateaus and keep losing weight, support muscle repair and building by:

  • Eating plenty of protein
  • Strength training

Healthy foods with a lot of protein include lean meats (e.g. turkey or chicken breast), eggs, low- or non-fat dairy, unsalted/unsweetened nuts or nut butters, and soy products. Try to consume around 0.8 grams of protein per kilogram of body weight per day, or even slightly more if you’re highly active and at a close-to-healthy weight. As an example: the average person 200 lb (91 kg) person should aim for a little over 70g of protein per day.

Incorporating strength training into your workout routine is also beneficial for both immediate and long-term weight loss. Since muscle burns more calories at rest than fat, building muscle mass – or trying to maintain it during a period of weight loss – helps keep boost the metabolism. Experts recommend including a combination of aerobic (cardio), strength training, balance and flexibility exercises into your regular fitness routine. Strength-building activities include: lifting weights, completing resistance training or body weight exercises (e.g. push-ups or plank), or climbing stairs.


3) “Cheat meals” add up

Have you ever tried one of those weight loss plans where you diet for five or six days and then have a day or two “off”? Or do you take your phentermine only on weekdays?

These on again-off again diets are understandably popular, but for many people the part-time schedule proves too good to be true. The logic is that if you create a big enough calorie deficit during the week, then it’s okay to let-up on the weekend and eat whatever you want.

Unfortunately, there are two big problems with this plan:

1) It’s too easy to undo all your hard work

If you diet all week and burn more energy than you consume, the weight should start to come off. Sadly, it’s deceptively simple to accidentally undo a whole week of healthy habits in a single day of junk food and overeating. If you subscribe to the “calories in, calories out” philosophy, weight loss is all about math. So, overeating – even if it’s just for one day a week – can definitely slow weight loss efforts.

That being said: there is absolutely a time and place for indulgence. Birthdays, graduations, weddings and holidays are perfect times to enjoy a “cheat day” (or meal). Partaking in fun, celebratory food is a big part of what makes festivities feel special, so go for it! Just make sure these less-than-healthy meals are something you enjoy on special occasions – not every day, night or week.

2) Healthy lifestyle > short-term diet

More than the risk of undoing your last week’s work, the idea of regular “cheat days” is problematic because it furthers the mindset of being on a diet that you’ll eventually stop.

Research repeatedly shows that the key to long-term weight loss is sustainable, healthy habits. So, if your diet involves constantly going back to old habits (and viewing healthy eating as a chore), this practice can prove detrimental to permanent weight loss.

How to Lose Weight Faster

Work on making healthy choices the norm, and thinking of treats as something you enjoy only on special occasions (like your birthday!). Its best if you can think about reasons why you want to lose weight and get fit, besides the number on the scale, as motivation to adopt this new lifestyle & mindset.

While it may be hard at first, but you will reap the rewards in the long run. When a craving strikes, try to focus on how good you feel when you nourish your body with healthy food in moderate portions.

It’s also easier to make this shift if you don’t go to extremes. After all, there’s a big difference between telling yourself you’ll never eat any sweets ever again versus deciding to limit your indulgence to a small treat just a couple of times per week!

4) Expectations exceed reality

Often times, when you start a new diet or exercise program you’ll experience rapid weight loss in the first couple of weeks. It’s wonderful to see the scale move so dramatically at first, but many people get discouraged when weight loss soon slows. The good news is this is perfectly normal! Here’s why:

That initial weight loss is largely due to a loss of water with glycogen. When you first start cutting calories and/or upping your exercise, the most available source of stored energy comes in the form of glycogen. As opposed to drawing on the fat stored all over our body, it’s easier to use up the readily-available energy from glycogen – a carbohydrate stored in the liver and muscles.

Since glycogen contains water, it releases a lot of water when it is burned for energy. For this reason, some people lose a lot of water weight in the first couple weeks of their diet. Eventually, however, your body switches to other sources of energy (e.g. stored fat) for fuel and this rapid weight loss ceases.

So, why does it take so long to lose weight? Sometimes it really isn’t taking that long, but high expectations make healthy weight loss seem slow. If you’re expecting this rapid drop to continue, either of your own accord or due to what you’ve seen online, that’s typically not realistic.

How to Lose Weight Faster

You can’t trick your body into burning glycogen forever – and you wouldn’t want to! If you’re putting in all of this effort to lose weight, you want your body to start drawing on its stored fat for energy so that that extra weight eventually goes away. In the meantime, try to embrace the fact that it’s perfectly normal for weight loss to slow, or even plateau for weeks or months at a time.

If your weight loss slows or plateaus, try:

  • Cutting calories (if you can do so and still stay above 1200 per day)
  • Increasing activity (either at the gym or in your daily life)
  • Assessing whether there’s any other habit contributing to your slowed weight loss (e.g. lack of sleep or poor meal planning)

Just remember: it’s absolutely normal to plateau! Don’t let a few days, weeks or months at the same weight discourage you from continuing on your long-term weight loss journey.
