Can Weight Loss Cause Acne?

If you’re overweight, getting on a healthy diet and trying to shed the excess lbs is always going to be a good thing for your body and health. But can weight loss cause acne? Some believe that the hormone changes caused by rapid weight loss can in fact cause acne breakouts. In this article, I’m going to discuss some reasons why weight loss might make you break out, and how to avoid it.

Does Weight Loss Cause Acne?

In short, no. But it’s a little more complicated than you might think. Technically, there is no scientific link between the loss of excess weight and the development of acne. Having your weight fluctuate typically has no direct impact on your levels of acne or breakouts.

So then why might you experience acne during a diet or weight loss program?

Basically, when you go on a restrictive diet, two things change. One, your body’s hormone levels fluctuate, which can cause acne. Secondly, your diet may change and you might be eating foods that previously weren’t part of your diet. The combination of these two factors can – potentially – lead to new acne breakouts. Let me explain: 

How Dieting Can Cause Acne

When you’re on a diet, it’s normal to switch up what you eat. But many of us want to shed the excess weight without drastically changing our diets or our budgets, so instead of switching to a clean, non-processed diet, we simply swap out high-calorie foods for their fat-free counterparts. Fat free yogurt, sugar-free soda – you know the types of diet foods I’m talking about. We’ve all eaten them, and I can totally understand why it might seem like a healthier option for someone trying to lose weight quickly.

The problem with this is that many sugar-free or “fat-free” diet foods are filled either with sugars or artificial sweeteners, many of which can spike your glucose levels and contribute to acne. Diet foods are a good example of “if it seems too good to be true, it is.” While you might not be drinking calories, your body is paying for the treat somewhere. There’s simply no way to drink a full bottle of soda without any ramifications.

So, if you want to lose weight without any pimply side-effects, one thing you can do is avoid the diet foods and “fat-free” alternatives and stick to a clean, whole food diet where possible. It’s also a good idea to be aware of so-called healthy “superfoods” that are actually super unhealthy and terrible for acne. I talk about these foods in my eBook, Unmasking Acne.

How Extreme Weight Loss Can Cause Acne

Another way weight loss can cause acne is by causing your hormones to fluctuate. When you lose weight rapidly, you might not give your hormones a chance to regulate themselves to your new weight. This new hormone imbalance can lead to the development of acne.  

Plus, when you’re on a highly restrictive diet – especially if you’re eating processed diet foods – it might be difficult for you to get the required nutrients and vitamins into your body. This can also have an impact on your skin, making it dull, tired and more acne-prone to boot.

Instead of going on a rapid calorie deficit, find a healthy way to cut weight and you’ll limit the toll of weight loss on your complexion. 

Another important point to make is that protein powders and extreme weight lifting are also both known to cause acne. Protein powders are often full of glucose-spiking sugars and caffeine, and extreme weight-lifting increases testosterone, which can temporarily cause breakouts. If your skin is sensitive to acne, you might want to leave the powders and heavy lifting and opt for some traditional cardio or toning exercises. 

Can Weight Loss Help Acne?

Yes! Don’t be discouraged by this article if you want to shed some excess weight. The main reason people develop acne during a weight loss regime is that they diet irresponsibly. Extreme dieting will deprive your body of essential nutrients and vitamins, while spiking its glucose levels with calorie-free artifical sugars.

Losing weight should actually help acne, as your hormones are more likely to be stable once you reach a healthy weight. This means less sebum and oil available to clog your pores. The key is just to lose weight healthily. 

The Bottom Line?

So, can weight loss cause acne? Yes and no. It all depends on how you go about losing the excess weight. Listen, I can totally understand those who put on weight over time and want to get rid of it as soon as possible. But is a lower number on the scale worth the detriment to your skin? 
To lose weight and keep acne at bay, lose the weight responsibly. Most nutritionists recommend 1-2 lbs per week for a healthy weight loss, as this gives your body, skin and hormones the time to adapt. You can also take a look at my eBook, Unmasking Acne, for a run-down on acne-friendly foods to incorporate into your diet.

Frequently Asked Questions

Can weight loss cause skin changes?

Yes, dramatic shifts in weight (either up or down) can cause hormone fluctuations. Whether your skin improves or worsens depends on how safely you lose or gain weight, and what changes you make to your diet.

Will losing weight help acne?

This completely depends on your current weight. If you are overweight and begin eating healthier, your skin will likely become more clear. However, if you lose too much weight and become undernourished hormone fluctuations could cause acne breakouts.

Hi I’m Sam Wood. I’m the chief editor, lead acne expert, and health coach behind GoodGlow. I’m also an author of one of the top selling acne books on Amazon, a husband, father of two, and a pretty good cook!

I’m so glad you found GoodGlow and hope the information I have spent the last 10 years cultivating will help you clear your skin and improve your overall health.

I began experiencing acne breakotus as a sophomore in high school, but unlike most of my friends, my acne actually got worse as I got into my 20s. I exercised regularly, ate healthy (or so I thought) and spent hundreds of dollars a month on high end skincare products and supplements to help clear my skin. Despite these measures my acne breakouts and scarring only got worse as the years wore on.

This greatly wore on my self confidence and mental health. Simple things like taking pictures or going out with a large group made me feel self conscious. So I avoided these situations whenever I could help it.

As a last ditch effort I decided to try an extremely restrictive diet recommended by a close friend with an autoimmune disease. After following this diet for about two months my skin started to clear for the first time in over 8 years. The good news is that this restrictive diet is not actually necessary for 99% of people to permanently clear their skin, and over the course of a few months I was able to add back about 90% of my “normal diet”.

After clearing my skin I spent the next 4 years self experimenting on myself with different diets, supplements, skincare products to try and find a pattern for what was triggering my acne breakouts. I even tried different meditation, ice baths, and accupuncture to try and isolate the root cause of the breakouts.

In the end I realized that an extremely restrictive diet was not necessary for clear skin. The most important thing to do is to avoid inflammatory foods in your diet. Some common examples of this are fried foods, alcohol, sugar, and dairy.

Most impoirtantly I stopped reading trendy websites for skincare advice and began reading medical journals authored by dermatologists and nutritionists. Although the information in the articles was great the information was not easily understandable to most readers (including me). I spent hours dissecting individual posts and looking up terms I did not understand. Over the next 6 months I gradually began to understand these journals and started self experiemting some of the research on myself.

After experiencing quite a bit of success personally, I started sharing my research on forums and with close friends struggling with acne. When I shared the research it was in easy to understand, plain English. Everyone I talked to loved what I had to say and kept asking more and more questions. So I decided to start a blog so I could just send someone a link when they asked a question instead of rewriting something I had sent 100 times before 😅

While the same directional principles apply to everyone, acne is very personal and should be treated on an individual basis. That’s ultimately why I created GoodGlow. To help everyone reverse engineer the root cause of their acne and clear their skin permanently.

To date I’ve helped over 2,500 people clear their skin using a natural, holistic approach.
