Having PCOS and trying to lose weight feels like an uphill battle every day. It’s not only about the stubborn weight that refuses to come off, no matter how much exercise or dieting you do, but it’s also about the unpredictable cycles and constant fatigue that come with unbalanced hormones. But what you eat can either fuel the struggle or turn the tide. This 21-day gluten and dairy-free meal plan teaches you to eat in a way that helps balance hormones, tame inflammation, and support steady weight loss.

How exactly does that work? You’ll find out in a matter of a few minutes by simply reading this article till the end.

Key Takeaways

  • What you eat plays a key role in managing PCOS symptoms, balancing hormones, and supporting weight loss.
  • Gluten is a protein in grains like wheat and rye, while dairy comes from milk-based products like cheese and yogurt.
  • This diet may help reduce inflammation, improve gut health, and increase energy levels.
  • Portion control, eating whole and unprocessed foods and maintaining a calorie deficit is still important if you are trying to lose weight.
  • A 21-day gluten and dairy-free meal plan can make it easier to get started on a healthy eating journey and build sustainable habits for the long term.

Typically, people who are not able to tolerate dairy may experience negative side effects like gas, diarrhea, cramps, bloating, hives, or itching upon consumption.

What Is a Gluten and Dairy-Free Diet?

A gluten and dairy-free diet is quite self-explanatory. It refers to a diet in which you are limited to eating and drinking foods that do not contain traces of dairy or gluten.

Anyone can choose to start a gluten-free and dairy-free diet, but some may have no choice but to follow it due to certain food allergies or sensitivities. Some may also find that this diet helps to resolve their skin issues, restore gut health, and help them feel more energized.

Why Choose a Gluten and Dairy-Free Diet for PCOS

Polycystic ovary syndrome (PCOS) is a condition that occurs when you have imbalanced hormones [3]. It can be caused by your ovaries overproducing the hormone called androgens, chronic low-grade inflammation, or insulin resistance. People with PCOS normally experience irregular menstrual cycles and unpredictable ovulation periods. Ovarian cysts can also occur due to the lack of ovulation.

One of the ways to manage PCOS symptoms and reduce inflammation is by eating a nutritious diet. While there’s a lack of evidence on whether removing gluten could be beneficial for people with PCOS, gluten in general can cause inflammation in the body for some people [4], [5].

Likewise, for dairy, there’s a lack of studies to support cutting out dairy to help manage PCOS symptoms. Going dairy-free can be useful for someone with PCOS if they also have an allergy to dairy or components of dairy.

Can You Lose Weight by Cutting Out Gluten and Dairy?

It is possible to lose some weight by eliminating gluten and dairy from your diet, but that is only if you establish healthy eating habits. Just because you opt for gluten-free or dairy-free options, it doesn’t necessarily mean that the food is healthy and that you will lose weight by eating them.

If you choose to consume an excessive amount of food and not maintain a calorie deficit, you will likely gain weight instead of losing it. In addition, you should also focus on eating more whole foods and reducing your intake of processed foods.

As per what registered dietitian Mia DiGeronimo says, “An apple and a gluten-free sugar cookie are both gluten-free, but their nutrients vary drastically“. You can have a gluten-free cake or sweet treat, but they could contain a lot of sugar and fat, making them high in calories.

Simple gluten and dairy-free meal plan guidelines to note

When you are following a gluten and dairy-free meal plan for the first time, here are some things that you want to make special note of:

  1. Ensure to check food labels carefully: Certain foods or sauces may sometimes contain gluten or dairy without you even realizing. It’s important to carefully check every food label to ensure that they don’t contain any traces and that they are labelled gluten-free or dairy-free. The best is to focus on fresh, whole foods to avoid accidentally buying foods with gluten or dairy.

If you are unsure whether a product is gluten-free or dairy-free even after checking the label, you can try scanning the food label with Eato’s free food scanning tool. It’s free up to 7 days!

  1. Try to meal prep more: Meal prepping at home not only saves time, but it also gives you more control over what you eat since you know what’s going into your meals. You can also avoid cross-contamination that way.
  2. Be aware of how your body feels: Try to journal down how you feel every time you finish a meal and whether you experience any strange symptoms. This can help you identify other potential food sensitivities and fine-tune your diet for better digestion, energy, and clarity.

How Else to Lose Weight If You Have PCOS?

PCOS can make it harder to lose weight, but not impossible. Beyond going gluten and dairy-free, here are some other approaches that may support better results:

Reduce your carb intake

Carbohydrates are broken down into glucose, which requires insulin to process them. A diet that is high in carbohydrates will, in turn, increase insulin levels. High insulin levels slow down fat burning and promote fat storage in the body.

Prioritize sleep and manage stress

High cortisol levels can disrupt hormone balance, so it is important to manage your stress well by engaging in self-care practices and making it a habit to get at least 6-7 hours of sleep per night.

Eat mindfully

Slow down, chew thoroughly, and pay attention to cues that tell you that you’re full.

Combine diet with regular exercise

Combining a good diet with exercise can help some women with PCOS to lose weight. The keto diet is one example that could help women shed some weight.
