As a new mom, I know what it’s like to be a busy woman who wants to regain her body (and energy). I created BeyondFit Mom to give women the tools needed to reach their fat-loss, health, energy, nutrition, and training goals. It’s not about a quick-fix program that leaves you floundering after a few weeks. BeyondFit Life is about results now and in the future. It’s about ongoing support, learning, education, and information sharing so you can take your results “BeyondFit” and into the rest of your life. I’m the founder of BeyondFit Mom, with a Bachelor’s degree in Health and Exercise Science. I’m a professional fat-loss expert with years of experience in helping women shed body fat, boost fitness, and learn how to live a fat-loss lifestyle. I’m also a mom to two little boys, and BeyondFit Mom is my other baby!

If PMS is leaving you feeling like you want to eat chocolate, ice cream, and pizza while lying on the couch for a week, this article is for you. The truth is that for many women, the weight and mood changes caused by your menstrual cycle can be significant. The symptoms of PMS vary by individual and can range from a slight inconvenience to feeling like PMS is taking over your life.

The most common PMS symptoms include:

  • Water retention and bloating
  • Irritability
  • Increased cravings
  • Appetite changes
  • Decreased energy levels

But the good news is that by making a few small tweaks to your training and nutrition, you can easily outsmart cravings and get a handle on this time of month with your weight loss goals.

Weight Loss and Your Menstrual Cycle

1. Increased weight gain from water

Bloating can be a significant issue for women. Some women report gaining as much as 5 to 10 extra pounds of water during their cycle. This jump on the scale is NOT fat. It’s simply excess water retention caused by female hormones, mainly estrogen. Estrogen directly stimulates several compounds called renin-angiotensin from the kidneys that lead to fluid retention. In general, this issue is most common for women who are on the pill. The amount of fluid that is retained is directly proportional with the quantity of estrogen found in the pill. Oral contraceptives that contain around 20 mcg of estrogen are recommended for women who want to avoid fluid retention. If you’re on birth control pills that have a high estrogen level, talk to your doctor about moving to something with lower estrogen levels. Other ideas for reducing water retention include increasing your water intake, make it your goal to get ½ your bodyweight in ounces of water daily, and limiting salty foods.

2. BCAAs for cravings and cortisol

Another secret weapon for addressing the brain chemistry changes are BCAAs. BCAAs are helpful for minimizing muscle breakdown and lowering cortisol, as well as boosting the brain chemicals GABA (our brain’s number one relaxing chemical) and glutamate. By balancing these stimulating and relaxing responses in the brain at a chemical level, we can stop cravings before they even start. BCAAs also help to control hunger.

3. Boost Serotonin and Dopamine

Be prepared for cravings to naturally increase during the time of PMS. To deal with the intense cravings during this time, cocoa can be helpful. Cocoa has been shown to raise dopamine and serotonin levels in the brain and to help blunt cravings at a brain chemistry level.

4. Cortisol impact & stress reduction

In addition to impacting insulin, both estrogen and progesterone impact cortisol. Specifically, they are are both anti-stress hormones, so as women enter the late luteal phase (PMS), cortisol levels tend to rise. This means that stress reducing activities such as leisurely walking, foam rolling, yoga, stretching and sleep are very important to keeping hormones as balanced as possible.

5. High stress endurance exercise

Long-duration moderate intensity cardio is a stressful form of exercise that directly impacts cortisol. While I don’t personally encourage this type of endurance exercise for optimal body composition, if you’re training for an endurance event and need to fit in long duration, moderate intensity cardio into your routine, this type of exercise would fit better into the follicular phase or the beginning luteal phase when levels are higher and cortisol levels are better balanced.

6. Insulin impact & when to drop carbs

Because both estrogen and progesterone impact insulin, it’s important to understand and balance the insulin impact on body composition. This can be done through the manipulation of carbohydrates during specific times of the month. Because estrogen makes a woman more insulin sensitive, most women can get away with eating more carbohydrates during the follicular phase. Normal carbohydrate intake at most meals with carbs coming after exercise to enhance muscle growth and recovery is ideal. In general, women seem to be less tolerant of increased carbohydrate during in the luteal phase, especially the late luteal phase, aka PMS time frame, so if you’re tracking carbs, it may be beneficial go lower in carbohydrates during the late luteal phase.

7. More muscle building

Studies show that the follicular phase may be the best time to focus on muscle building as well. Due to the higher cortisol levels during the luteal phase, the body naturally tends to be more catabolic (muscle breakdown mode) during that time. The follicular phase is a naturally more anabolic (muscle building) time so make sure you’re using heavy weights and challenging your muscles to grow during this time. Full body weight training with heavy weights is key.
