Change Your Metabolism, Lose Weight, Take Control

Simply put, refined carbohydrates and sugars contribute to brain damage, diabetes, cardiovascular disease, and obesity. Studies suggest that low-carbohydrate diets can boost metabolism and support greater weight loss. In this article, we explore why insulin is known as the “fat hormone,” how sugar and refined carbs impact your metabolism, why the type of carbs you eat matters, how exercise acts as a magic pill, and how intermittent fasting combined with a low-carb diet can transform your biology and help you maintain a healthy weight.

 

Why Insulin is Called The FAT Hormone? 

The study of insulin and insulin resistance is at the forefront of medical research. Insulin, a hormone produced by the pancreas, acts as a chemical messenger that regulates blood glucose levels. Its primary role is to maintain blood glucose homeostasis, keeping levels within a tight range because both high and low blood glucose levels can be harmful to the body.

Insulin levels tend to mirror glucose levels—when glucose rises, insulin follows. Insulin is also a key hormone in fat storage. Elevated insulin levels stimulate fat cells to absorb glucose (from sugar and refined carbs) and convert it into fat, a process known as lipogenesis, which contributes to weight gain and obesity. This is why insulin is often referred to as the “fat hormone.”

When insulin levels are low, the body can access stored fat and use it for energy. Since high insulin levels are linked to chronic health issues like obesity, metabolic syndrome, and diabetes, maintaining lower insulin levels is crucial for long-term health.

 

The solution to lower your insulin levels, therefore, is rather simple:

1. Don’t put sugar or refined-carbs into your body.
2. Burn off the sugar and refine-carbs before eating more of them.
3. Introduce periods of intermittent fasting to break the cycle of eating.
4. Exercise to burn the excess sugar and refine-carbs.

 

Waist to Height Ratio TEST:

One of the earliest symptoms of excess insulin or insulin resistance is an expanding waistline as the body stores fat in your abdomen. There’s a simple yet effective test you can do to determine if your insulin levels are in range. 

To get your ratio, just divide your waist measurement by your height. A waist-to-height ratio of less than 0.5 shows good insulin range, while a number higher than 0.5 shows elevated insulin or insulin resistance.

 

Why sugar and refined carbs are the culprit?

Carbohydrates are a broad category of sugars, starches, and fibers found in many foods, including fruits, vegetables, legumes, dairy, and grains.

Different types of carbohydrates are digested differently, affecting metabolism and insulin levels in various ways. In general, the more processed, refined, or “low-quality” the food, the faster it impacts insulin levels. A diet high in refined carbohydrates—like white bread, white rice, pasta, and pastries—can spike blood sugar levels, leading to elevated insulin. High insulin levels contribute to weight gain, obesity, and inflammation.

Unfortunately, sugars and refined grains make up a large portion of the carbohydrates in modern diets, fueling the rise of obesity, diabetes, and metabolic disorders.

 

Carbohydrates in a nutshell!

Simple Carbohydrates

Simple carbs, like glucose and fructose (monosaccharides), are quickly absorbed into the bloodstream and used for energy. Some, like disaccharides, consist of two simple sugars linked together. These carbohydrates cause rapid spikes in blood glucose and insulin levels. Excess sugar is converted into fat and stored, often around the abdomen.

Refined Carbohydrates

Refined carbs stripped of most fiber, vitamins, and minerals, are considered “empty” calories. They digest quickly, have a high glycemic index, and lead to rapid blood sugar and insulin spikes after meals. These spikes mirror insulin levels, contributing to weight gain and metabolic disorders.

Complex carbs, such as oligosaccharides and polysaccharides, are made of longer sugar chains and are found in vegetables, legumes, and whole grains. They break down slowly, causing a gradual rise in blood sugar. Research suggests that replacing simple sugars with complex carbs can help reduce body weight and stabilize blood sugar levels.

What do raw vegetables, whole grains, brown rice, and quinoa have in common? They are all excellent sources of dietary fiber, a carbohydrate that breaks down slowly without significantly raising blood sugar. Fiber prevents obesity by promoting satiety and regulating digestion. Unlike other carbs, fiber doesn’t convert into sugar; instead, it adds bulk to stool, prevents constipation, and supports gut health. By drawing water into the stool, fiber helps food move efficiently through the intestines and aids in blood sugar regulation.

 

Why low-carbohydrate diets are better than low-fat diets?

The debate over which diet is better for weight loss and maintenance, low fat or low carbohydrate—is becoming clearer. Research shows that low-carb diets are more effective at increasing fat loss, reducing hunger, and balancing blood sugar levels. In a 6-month study of 132 people with obesity, participants on a low-carb diet lost over three times as much weight as those on a low-fat, calorie restricted diet.

Among the three macronutrients, carbohydrates, protein, and fat, carbs have the greatest impact on blood sugar and insulin levels. For this reason, low-carb diets can be particularly effective for weight loss and managing insulin.

Low-carb diets generally restrict refined foods like sugary drinks, baked goods, candies, and sweets. Some versions may also limit healthy carb sources, such as grains, starchy vegetables, high carb fruits, pasta, and legumes. Instead, they emphasize increasing protein and fat intake from wholesome sources like fish, meat, eggs, nuts, high-fat dairy, unprocessed oils, and non-starchy vegetables.

Here is a sample of different types of Low-Carb diets:

• Very low-carb diets: less than 10% of total daily calories, or 20–50 grams per day on a 2,000-calorie diet
• Low-carb diets: less than 26% of total daily calories, or fewer than 130 grams per day on a 2,000-calorie diet
• Moderate carb diets: 26–44% of total daily calories

 

But here’s why going too low on carbs and calories could be harmful:

It is important to avoid going to extremes with calorie or carbohydrate restriction, especially for women. Research by Erdélyi et al. (2024) highlights that reducing carbohydrate intake below 120 grams per day can contribute to fatigue, hormonal imbalances, and a decline in overall well-being. Carbohydrates play a vital role in hormone regulation and energy metabolism, particularly during the menopausal transition when hormonal fluctuations are already significant.

Additionally, very low-calorie diets, specifically those under 1200 calories per day, have been shown to increase the risk of nutrient deficiencies and further disrupt hormonal balance. Restricting calories too aggressively can suppress thyroid function, elevate cortisol levels, and even impact reproductive hormones such as estrogen and progesterone.

In summary, an effective and sustainable diet plan for women in midlife should prioritize high-quality protein, 30–45 grams of fiber per day, and a moderate intake of carbohydrates (not less than 120 grams daily). It should also avoid unnecessary food group elimination or overly restrictive calorie limits. As Erdélyi et al. (2024) conclude, under-eating or skipping essential macronutrients can often do more harm than good, especially during a time of major physiological change.

 

Intermittent Fasting: A Metabolic Game Changer!

Intermittent fasting (IF) involves cycling between periods of eating and fasting and when done correctly, it can be a powerful tool for metabolic health. Research shows that intermittent fasting offers more than just fat burning, it can help prevent type 2 diabetes, heart disease, age-related neurodegenerative disorders, inflammatory bowel disease, and even certain cancers.

The process is simple but impactful: when you fast, insulin levels drop, prompting the body to tap into stored fat for energy. As blood glucose decreases, the body begins to shift from sugar-burning to fat-burning mode.

There are two common approaches to intermittent fasting:

• Time-Restricted Feeding (TRF): Eating within a daily window (e.g., 16:8 — fasting for 16 hours and eating in an 8-hour window). This method is easier to maintain and puts less stress on the body when done earlier in the day.

• Alternate-Day Fasting (ADF): Alternating between days of normal eating and days of significant calorie restriction or fasting. This approach can be more intense and may not be suitable for everyone.

A great place to start is the 12:12 method, where you fast for 12 hours and eat during the other 12. Over time, you can progress to 16:8, or even a 20:4 window — but it’s important to listen to your body and move at a pace that works for you.

During fasting windows, water, herbal tea, black coffee (with or without a splash of cream), and bone broth are permitted. However, what you eat during the eating window still matters — focus on whole, low-carb, nutrient-rich foods, and avoid processed sugars or refined carbs.

 

But What About Hormones?

While intermittent fasting clearly supports metabolic health, its hormonal effects, especially for women, are more complex.

Emerging research, such as the study by Kim et al. (2021), reveals that fasting impacts hormonal rhythms in notable ways. Prolonged or poorly timed fasting may suppress thyroid hormone (T3), raise cortisol levels, and disrupt reproductive hormones like LH (luteinizing hormone) and estradiol. These disruptions can lead to menstrual irregularities or even slow down metabolism.

This is why timing and duration are critical.

In my understanding, early Time-Restricted Feeding (eTRF), for example, eating between 8 a.m. and 4 p.m., appears to offer the most benefits while minimizing stress on the body. In contrast, more aggressive approaches like 24-hour fasts or ADF may elevate stress hormones and should be approached with caution, especially by those with thyroid imbalances or adrenal fatigue.

Ultimately, intermittent fasting is not one-size-fits-all. It needs to be adapted based on your age, hormonal profile, and health history. When done right, it can be a powerful part of a metabolic reset but it must be approached with care.
