Stop Chasing Skinny: The 10 Dangers of Low-Calorie Diets

Stop Chasing Skinny:  If you’re a woman over 40, chances are you’ve chased weight loss.

You’ve tried the diets. The cleanses—the 1,200-calorie plans. You’ve probably lost weight—only to gain it back again. It’s exhausting. And it’s doing more harm than good.

Low-calorie diets don’t just leave you hungry. They break down your metabolism, steal your energy, and make it harder to live the strong, active life you deserve. Here The 10 Dangers of Low-Calorie Diets why it’s time to stop chasing “skinny” and start building habits that support long-term health.

1. They Make You Hungrier

When you cut calories too low, your hunger hormones (like ghrelin) go up. Cravings increase. You start thinking about food all the time. It becomes harder to stay disciplined, which often leads to overeating or bingeing later on.

2. They Slow Your Metabolism

Your body is smart. When it doesn’t get enough fuel, it slows down your basal metabolic rate (BMR)—how many calories you burn at rest. You start burning fewer calories throughout the day, even while doing the same activities. That’s why weight loss stalls, even if you’re eating “less than ever.”

3. They Cause Muscle Loss

Without enough calories—especially protein—you don’t just lose fat. You lose muscle. This is especially harmful as you age, since muscle supports balance, strength, metabolism, and overall quality of life. Losing it makes daily tasks harder and slows your fat-burning engine even more.

4. They Decrease Daily Movement

When your body’s underfed, it naturally reduces how much you move. This isn’t just exercise—it includes basic daily movement like walking, fidgeting, and even posture. This drop in non-exercise activity (NEAT) leads to fewer calories burned and less energy overall.

5. They Zap Your Energy

Low-calorie diets leave you drained. You’re tired in the gym. You skip walks. You say “no” to the things that make life fun—hikes, adventures, and playing with your kids or grandkids. If your goal is to feel better, not worse, then under-eating won’t get you there.

6. They Disrupt Thyroid Function

Your thyroid controls your metabolism. When calories stay too low for too long, your active thyroid hormone (T3) drops. That leads to fatigue, mood swings, and stalled fat loss. It’s a hidden reason many women can’t lose weight, even while dieting.

7. They Lower Leptin, the Fullness Hormone

Leptin tells your brain you’re satisfied. But dieting lowers leptin. That means your brain never quite gets the message that you’ve had enough—even when you just ate. Over time, this leads to more cravings and emotional eating.

8. They Increase Cortisol (Stress Hormone)

Crash diets raise cortisol levels. Cortisol increases belly fat, disrupts sleep, and makes you feel anxious or irritable. High stress plus low food is a recipe for burnout—physically and mentally.

9. They Lower Testosterone

Yes, even in women. Testosterone supports muscle, energy, and confidence. In men, low-calorie diets tank testosterone fast. For women, even small drops affect how strong and capable you feel. It also increases the risk of muscle and bone loss as you age.

10. They Increase the Risk of Regaining Weight

Extreme diets don’t work long term. Studies show most people regain the weight—and often more—after the diet ends. Why? Because the body is in survival mode. Once normal eating resumes, weight rebounds faster than it came off.

So What Should You Do Instead?

The scale is stupid and an unfair representation of what true success looks like.  Instead of chasing a number on the scale, focus on fueling your body to live strong, energetic, and capable.

Here’s what that looks like:

  • Eat enough food to support your activity and lifestyle. (It has to be more than your basal metabolic rate…)

  • Prioritize protein to build and preserve lean muscle, while improving your metabolism.

  • Strength train 2–4 times a week.

  • Walk daily and move often.  7,500 steps per day is the magic number.

  • Sleep 7–9 hours a night

  • Stay hydrated, drinking at least 1/2 your bodyweight in water.

  • Choose mostly whole foods, but allow flexibility.

  • Stop punishing your body—start fueling it.

If your current plan leaves you tired, weak, or obsessed with food, it’s not working.

You deserve to feel strong. Energized. Capable. And proud of how you live your life—not just how much you weigh.

Build habits that last.

Because being healthy and powerful at 60 starts with the choices you make now.

Be Strong. Be Fueled.

Be Great Today.
