Define Undereating and the Dangers + Symptoms

The “Diet” of our mothers (calories in vs. calories out) may give initial weight loss but over time slows down our metabolism and messes our hormones. 

Tune in to hear how Amber started dieting when she was 16 and was stuck to scale with constant hunger pains and mood swings!

The concept of calories in vs. calories out or move more and eat less can help someone lose initial weight since there is a calorie deficit, but eventually undereating (eating less than 1200 calories a day) leads to feeling tired, frazzled, and hungry which can lead to binging.

Over time our body does something amazing and protects itself by turning on the anti-starvation system. This means cortisol increases (stress hormone), there is a decrease in leptin hormones (hunger regulation in the brain), and the metabolic rate (metabolism) actually slows down.

I’ve been in this cycle and seen so many clients come from this place… Eat less, push hard, eat even less, push even harder, plateau hits, your left feeling discouraged, frustrated, and end up binging again and feeling defeated. THIS is my passion to end this diet cycle for women! Really to end ALL diets!

Symptoms of Undereating

Low energy, headaches, need nap/coffee to get through the afternoon, mood swings, binging, always feeling cold, hair loss, or missing periods.

How to Avoid the Dangers of Undereating while Still Increasing Fat Loss

1. Intermittent Fasting

“Intermittent Fasting” is a hormone supporting, blood sugar-stabilizing, eating SCHEDULE – not a diet – if done safely and correctly.

Tune in to hear how it was actually Amber’s husband that first introduced her to intermittent fasting years ago before it was a common practice, as a way to regulate her blood sugar moodiness and that “hangry” feeling.

What does intermittent fasting look like?

Amber recommends following the 16:8 method. This is where you eat for 8 hours of the day and fast for 16. Typically, the fasting window begins at 8:00 PM and ends at noon the next day! However, there are many ways to do it. Tune in for some helpful tips and guidelines!

How does it help?

It increases hormonal output, regulates blood sugar, reduces the risk of diabetes, increases metabolic rate when done correctly – meaning when we eat ENOUGH of the RIGHT foods.

2. Eating ENOUGH of the right foods at the right time

How much is ENOUGH?  We support our hormones, increase our metabolism, and see great body composition changes when we eat enough of the right foods at the right time. 

Tune in to hear Amber’s personal story of her mindset change, what it took to forget the scale, and how she began fueling her body!

Changing from a deprivation mindset to a mindset of fueling our bodies to be at optimal energy and wellness is key. Do you like yourself? We need to fuel our bodies as we like ourselves. 

Fuel = Whole foods. Eat foods that are from the ground or have a mother – to feel satisfied.

This takes my clients a few weeks to get to a point of fueling their bodies well and changing that mindset. People are afraid to eat! Once they do, amazing things happen in their bodies! Energy increased, the mood is stabilized, no more hangry feeling. PLUS the hormones are happy which means metabolism kicks in and they are able to start seeing major fat loss.

Listening to Your Body

It is important to listen to the body. Are you satisfied while fasting? Is your energy? How are your workouts? Are they strong? OR you can track macros with a free calculator like MyFitnessPal for a few days to see how much MORE food you need to eat!

Resource: Seriously, what the heck is a MACRO?

Avoid long term low carb “diets” – the thyroid (our hormone center) thrives on carbs (healthy, whole-food carbs).  FASTer Way teaches how to Carb Cycle: eat low carb a few days a week for fat burn and then follow that with higher carb days the rest of the week. Former keto clients who started carb cycling found they sleep better right away and they never feel deprived! A great balance.

Tune in to hear what Amber’s diet is like and examples of high and low carb foods that you can easily implement into your diet!

Closing Thoughts: Mindset is key.

“Diets” will only give you short term results and leave you frustrated.  Let’s change that cycle, avoid the dangers of undereating, and change our mindset to a healthy respect for our bodies for generations of women following our footsteps! Get started easily by waiting until 11:00 AM or 12:00 PM to eat and follow that with ALL the whole foods you can eat in 8 hours. You can get a free starter kit for intermittent fasting on my website including more of the science behind the strategies discussed here + whole food recipes.
