5 Weight Loss Mistakes Beginners Make
Introduction
Have you ever wondered why your weight loss efforts seem to always hit a roadblock? A successful weight loss journey isn’t just physical; it’s a mental journey. There are bound to be mistakes made along the way. But knowing some of the most common weight loss mistakes can you help you avoid them.
The first hurdle is recognition, and this post aims to guide you through it.

1. Trying To Do Too Much At Once Is One Of The Weight Loss Mistakes We Are All Guilty Of
I think that anyone who has had weight loss struggles knows this feeling. You make a plan on Sunday that from Monday, you will eat 1200 calories and go for a run every day.
Then you follow through Monday and Tuesday, maybe Wednesday you start to slip, and by Friday youโve given up. Now you feel like a failure and itโs a downward spiral, youโve set yourself up to fail.
This was my biggest problem – Iโve always had an “All or Nothing” approach, and not just to weight loss! If I wasnโt 100% in, what was the point? But I would quickly become overwhelmed, and would be so hard on myself for โfailingโ. I would convince myself that I could never do it, and would never be able to stick to anything.
Long-term sustainable weight loss is made up of small habit changes over-time.
Instead, you should be looking at your โunhealthyโ habits, maybe even listing them down. And focusing on making small changes at a time.
Weight loss is 80% nutrition.

Focus On One Thing At A Time
I recommend focusing fully on nutrition at the start of any weight loss journey. Weight loss is 80% nutrition and 20% exercise. You can lose weight without exercise, but trying to lose weight just by exercising, although not impossible, is very difficult. I would say a month is a great amount of time to focus on this area before introducing any exercise plans. But you may need a shorter or longer amount of time – itโs completely up to you! If you already do some exercise or just want to get moving more, you can carry on with these as normal.
What this nutrition change looks like will vary from person to person. You might want to and be able to take bigger steps e.g. cut out refined sugars altogether. But if youโre not ready for that you can take a look at certain food habits you have and start changing them slowly.
And once you do want to start bringing exercise in, start one thing at a time. Depending on your fitness levels, you can start by going out for walks. Find something fun that you enjoy doing (this is a tip by itself), or whatever you want really! And once you have gotten into the habit you can start adding in more intense exercises or programs, etc.
Feeling stuck? It might be more than just these common beginner mistakes. I also dive into some motivation mistakes in No Motivation for Weight Loss?.
2. Letting One โBadโ Meal Ruin A Day
All foods in moderation!
This comes back to that โAll or nothingโ mentality.
Youโve been โgoodโ all day, youโve had a salad, some fruit, and a low-fat yogurt. Then someone comes along and offers you a slice of cake, or pizza and you just canโt resist it. Thatโs OK!
But my mindset in the past always told me I had already ruined the day, so why continue eating healthy? And then the binge monster would kick in with promises of โtomorrowโ.
And the cycle would inevitably repeat.
Iโm going to be honest here, this pattern is not easy to get out of. I wonโt say itโs something that comes naturally to me yet. I have to make a conscious effort to remind myself that Iโm allowed foods in moderation.
If youโre thinking ‘I need to do everything perfectly,’ you might be sabotaging yourself. Learn more in my post on All-Or-Nothing Thinking.
Losing Weight Is Calories In VS Calories Out
We all know that losing weight is calories in vs calories out, so letโs look at the numbers.
To lose 1lb of fat a week, I need to eat 1700 calories (Based on my TDEE (Total Daily Energy Expenditure) of 2200). A slice of red-velvet cake (my absolute favourite!) has 293 calories, are there more filling meals out there with fewer calories? Sure! But itโs not that bad. That slice of cake would count for 17% of the calories I would eat that day, the dayโs not ruined!
And this doesnโt just go for the day either, donโt let a bad day ruin the week! I call this “โThe Monday Mindsetโ, the โIโll start again on Mondayโ. Your body doesnโt know the days of the week!
Just pick yourself up as soon as you can and start working towards being more flexible, and eating healthy while enjoying treats in moderation.

3. Trying To โMake Upโ For Overeating
Restricting too much will often lead to overeating later on.
This is kind of the opposite of the last one. Instead of letting a โbadโ meal lead to a binge, it leads to trying to restrict further.
So youโve just had a few slices of pizza for lunch (can you tell I love pizza?) instead of the salad you planned, youโre feeling guilty and so you tell yourself that youโre going to skip dinner and just have a snack in the evening. Or like me, you tell yourself youโre not going to eat again for the rest of the day.
And my 6 pm, youโre starving, and by this point, the healthy dinner you originally had planned (before your โbadโ meal) isnโt going to cut it, and you end up overeating.
You should never starve yourself to make up for eating more calories than planned. You can adjust your calories around this extra meal you had, but again, if you look at the numbers (the 293 calories from a slice of cake for example), youโll find that most of the time you can continue as normal. Eating 293 extra calories in a day isnโt going to lead to weight gain if you are already in a calorie deficit, and even if it puts you in a calorie surplus, itโs only one day! You would need to eat 3500 calories extra to gain a pound.
4. Not Having Enough Non-scale Goals Is One The Easiest Weight Loss Mistakes To Make
Weight loss can be your overall goal, but it is also a long process, and working towards sustainable weight loss can take years.
One HUGE factor in my own weight loss and staying motivated to lose weight was running.
Over the last couple of years, I have come to love running, which is something I never thought I would say. And the reason for this is that itโs something I can see progress with, that has nothing to do with weight. Each week I can run a little bit further, I can feel the difference in my breathing, my legs ache less, I get faster, etc.

Running my first 5K felt so much better than any amount of weight loss I have seen on the scales, after running my first 10K I was gleaming with pride for weeks! Iโm running a half marathon this year and I genuinely think my head may explode from excitement when I finish it.
Set Goals That Give You A Sense Of Achievement
Realising how these non-scale victories were benefitting me so much, I started setting new goals – earlier last year I nailed my first push-up after months of trying. Iโm currently working towards a pull-up (although this oneโs proving much more difficult).
The reason these goals work so well to keep you motivated is that although you may be able to see a 1lb-2lb loss on the scale, you canโt really see or feel it straight away. It can take months to start noticing weight loss.
If you set yourself a โperformanceโ target, it may take a while to reach that goal but it is more measurable as you are working towards it. You can measure your pace or distance while running, go down a little bit further when trying to do a push-up, start lifting heavier weights and, feeling stronger.
And if your nutrition is in the right place, these goals will still contribute to your weight loss. Because you have found an exercise that you will do regardless of how many calories it burns.

5. Weighing Too Often And Letting Fluctuations Demotivate You
I used to jump on the scales every morning. And my weight loss/gain would massively affect my mood for that day.
There will always be weight loss fluctuations.
Or even when weighing myself weekly, seeing no loss or a gain after a โperfectโ week would frustrate to me so much and leave me feeling so dejected that I would have just wanted to quit there and then.
There are so many reasons that your weight can fluctuate! And most of the time it just comes down to your body holding onto a bit of water weight, for various reasons. I tracked my weight every day for a month, see the results here.
Weight Loss & Fat Loss Are Not The Same
Carbs have a huge impact on water weight, thatโs why people doing Keto will usually see a big loss in the beginning. This is because, for every gram of carbs you eat, your body can store between 3-4 grams of water. So if you happen to have had a bigger/higher carb meal than usual, it may look like you have gained 1-3lbs the next day, but this isnโt real weight. To gain 3lbs overnight you would have to have been in a 10,500 calorie surplus..in one day! And while Iโm not saying that this is impossible, the average person would not be able to eat that much in one day. Thatโs around 5 large pan pizzas, on top of your maintenance calories!
Another factor in retaining extra water weight is exercise. This is because when you exercise, you can cause micro-tears and in your muscles (this is good!). This is how your muscles get stronger. You get the micro tears, your body heals them, your muscles become stronger.
During this โhealing phaseโ your body retains extra water around your muscles to help the process along. You may experience general aches or DOMS (Delayed onset muscle soreness). Thatโs why itโs so important to rest after strenuous activities – to give your body the time to heal. And the water weight increase will go back down.
There are so many things that can affect your weight – hormones, stress, sleep, etc.
As long as you have been in a calorie deficit overall, you will lose weight. Itโs better to look at your averages of weight loss over some time rather than checking every day if you have lost anything.
Overthinking every step? Try simplifying your approach and losing weight without the mental overwhelmโhereโs how in How to Lose Weight Without Thinking About It.
