Foods to Avoid when Taking Metformin for PCOS:

Certain foods can interact with metformin and cause undesirable side effects. To avoid these side effects, it is important to know which foods to avoid while taking metformin. Here is a list of some of the most common foods to avoid while taking metformin.

Foods High in Sugar:

One of the most important things you can do to help control your blood sugar is to watch your diet. This means knowing which foods to eat—and which foods to avoid.

Foods High in Sugar:

If you have metformin for PCOS, you’ll need to be especially careful about the amount of sugar in your diet. That’s because metformin works by helping your body better use the insulin it makes, and when you eat sugary foods, your body has to produce more insulin.

Too Much Insulin Can Lead to Weight Gain, so It’s Important to Limit the Amount of Sugar in Your Diet. Here Are Some Tips:

  • Read food labels carefully and avoid processed foods that contain added sugars.
  • Limit sugary drinks like soda, sports drinks, and fruit juices.
  • Choose fresh fruits and vegetables instead of sugary snacks.
  • When you do eat sweets, be sure to pair them with other foods that contain protein or fat so you don’t spike your blood sugar too much.

Foods High in Carbohydrates:

You’ll want to limit or avoid high-carb foods when you take metformin. That’s because the drug works by lowering your blood sugar, and high-carb foods can cause your blood sugar to spike.

Some Examples of High-Carb Foods Include:

  • Bread
  • Pasta
  • Rice
  • Cereals
  • Fruit Juices
  • Sodas
  • Sports Drinks
  • Desserts


It is advisable to avoid alcohol while taking metformin since it can increase the risk of lactic acidosis, a potentially fatal condition. If you do drink alcohol, try to limit it to one or two drinks per day.

Foods to Eat with Metformin:

If you’re taking metformin for PCOS, you might be wondering what foods you should eat. Metformin can cause gastrointestinal side effects like diarrhea, so it’s important to eat foods that are easy on your stomach. Here are some suggested foods to eat when taking metformin for PCOS.

Foods High in Fiber:

You should aim to include foods high in fiber when you’re taking metformin. Fiber can help regulate your blood sugar levels, and it’s an important nutrient for overall health. Good sources of fiber include:

Whole grains: oats, barley, quinoa, farro.

Beans and legumes: black beans, kidney beans, lentils.

Fruits and vegetables: apples, carrots, sweet potatoes, broccoli.

Nuts and seeds: chia seeds, flaxseeds, almonds.

If you’re not used to eating a lot of fiber, increase your intake gradually to avoid digestive issues. And be sure to drink plenty of water throughout the day to keep things moving smoothly.

Foods Rich in Antioxidants:

Studies have shown that adding foods rich in antioxidants to your diet can help to improve the effectiveness of metformin. Antioxidants help to protect cells from damage, and this can help to improve insulin sensitivity and blood sugar control. Good sources of antioxidants include:

  • Fruits Such as Berries, Cherries, and Grapes.
  • Vegetables Such as Broccoli, Kale, and Spinach.
  • Whole Grains.
  • Nuts and Seeds
  • Tea.
  • Dark Chocolate

Lean Protein:

If you have PCOS and are taking metformin, you should make sure to include lean protein in your diet. Protein is an essential nutrient for the maintenance of muscle mass, which can be important for both PCOS and Type 2 Diabetes. By including lean protein in your diet, you will be more likely to maintain your weight, which will make it easier for your body to use the metformin effectively.

Lean protein sources should provide about 20 to 30 grams per Lean protein can help regulate blood sugar levels and insulin levels, both of which are important for managing PCOS. Good sources of lean protein include chicken, fish, tofu, legumes, and eggs.

• You should include lean protein at least twice a day.
• Lean proteins are low in carbohydrates and can help you maintain a healthy weight.
• Lean proteins such as fish, eggs, and chicken are healthy, natural and inexpensive.
• Lean proteins break down slowly, so they don’t spike blood sugar levels.
