How Fad Diets Mess up Your Hormones?

What Are Fad Diets ?

Fad diets are popular diets that promise faster weight loss or other health advantages with minimal effort.

They typically have no scientific support and are not long-term viable. Here are a few examples:

• Diet for Cabbage Soup

• Keto (when overdone or misused)

• Cleanses for detoxification

• Diets extremely low in calories (VLCDs)

• Raw food-only or carnivorous diets

Why are fad diets popular but misleading?

Fad diets are easy and are successful at first because they remove the main food groups, make a calorie deficit, cause a loss of water

However, this weight loss is rarely long-lasting and may eventually have a detrimental impact on hormonal health.

Problems like irregular periods, infertility, weight gain, insulin resistance, exhaustion, anxiety, and even chronic long-term diseases can result from hormonal imbalances.

Are Your ‘Healthy’ Diets Messing with Your Hormones?

1. Extreme Calorie Restriction

Many fad diets rely on more calorie cuts, which can send your body into “starvation mode.” What’s the point of a flat stomach if your energy crashes by 3PM? These all disrupts:

• Leptin and ghrelin, leading to increased hunger and reduced satiety.

• Thyroid hormones, slowing down metabolism.

• Reproductive hormones, causing menstrual irregularities or amenorrhea in women.

2. Low Carbohydrate Intake

Carbs are essential for:

• Balancing cortisol (stress hormone)

• Producing serotonin (mood and sleep regulator)

• Supporting insulin sensitivity

Extremely low-carb diets (like keto) may result in chronic fatigue, mood swings, or elevated cortisol levels due to stress response.

3. Fat-Free or Low-Fat Diets

Healthy fats are critical for:

• Hormone synthesis (especially estrogen, progesterone, and testosterone)

• Absorption of fat-soluble vitamins (A, D, E, and K)

Avoiding fats can lead to imbalances in sex hormones, leading to PMS, acne, low libido, and fertility issues.

4. Detox and Cleanse Diets

These diets often cause rapid weight loss due to water retention and no fat loss as such that lead to:

• Blood sugar instability

• Electrolyte imbalances

• Adrenal fatigue due to elevated cortisol from chronic undernourishment

Best Diet for Hormonal Balance (What to Eat)

To support hormonal health, a more sustainable, whole-food-based approach is recommended:

• Include complex carbohydrates (quinoa, oats, brown rice) for energy and hormone regulation.

• Add healthy fats (avocado, nuts, seeds, olive oil) for hormone production.

• Prioritize lean proteins and plant-based proteins.

• Manage meal timing and avoid prolonged fasting unless medically advised.

• Ensure micronutrient sufficiency, especially iron, B vitamins, magnesium, and zinc.

Conclusion

Fad diets may deliver short-term results but often compromise long-term health, especially hormonal balance. Hormones are delicate, and restrictive or extreme dietary practices can tip the scale toward dysfunction.

As a health coach I recommend instead of chasing quick fixes, aim for a sustainable, nourishing diet that honors your body’s natural rhythms.

In today’s social media world, it is common to be flooded by people claming fast weight loss by doing various diets. From keto and intermittent fasting to juice cleanses and detox teas, fad diets have surged in popularity.

But while these diets offer rapid weight loss, the long-term implications especially on Hormonal Health are often overlooked.

A 2020 review in the Journal of Clinical Endocrinology & Metabolism found that restrictive diets can lower reproductive hormone levels in women and delay ovulation.

Let's try to understand what these fad diets actually signify.
