Will Eating Less Cause Weight Loss? The Answer Is Here!

If you are trying to lose weight, many people will advise you to cut as many calories from your diet as possible. So, will eating less cause weight loss? Let’s see!

0. This misconception is still prevalent

This misconception is still prevalent.

Weight loss is a complex process. Simply put, it results from an energy deficit – i.e., burning more calories than you eat.

So, does it mean will eating less cause weight loss? The answer is Yes.

Eating less is effective for short-term weight loss. In the long run, not only will it reliably help your body lose weight, but it will do more harm than good.

This post will prove you don’t have to eat less to lose weight. Instead, you will need another solution. Let’s give it a read!

2. Starving the body is not wise

Starving the body is not wise

In theory, body fat is the result of excess energy. If you consume less energy than you are using, you will lose weight. So, eating less can cause weight loss.

Most studies show that, in the long run, dieting rarely works. Unfortunately, this false trend is widespread.

When it comes to weight loss, many people refrain from overeating. Unfortunately, however, your body will lower its metabolic rate, resulting in fewer calories burned.

When that happens, your body will start to burn fewer calories per day, making it much harder to get thinner. However, the problem is not only that.

If you don’t provide your body with the energy it needs to function daily, it will have to start looking elsewhere for energy. Specifically, it will begin to break down lean muscle mass for energy. As your muscle mass decreases, your body’s metabolism declines even more.

So, fasting is not a good way. However, if you decide to cut calories, do not rush. In the beginning, it is wise to cut about 300-500 calories per day from the usual diet.

By cutting a few hundred calories per day, you can lose about 1-3 lbs per week. The amount of weight that you lose is mainly due to fat loss, not muscle loss. If your weight loss falters for a few weeks, you should just cut back a few hundred extra calories or consider exercising a little more.

In short, undereating or even starving yourself to lose weight is a misconception. However, if you do not accept this fact, you may face many adverse side effects, such as faster weight gain or disturbances in your metabolism and hormones.

Undereating is not a healthy solution. Getting thinner is easy as pie if you follow the proper methods. However, let’s start with the harmful effects of eating less.

What Are the Side Effects of Starving the Body?

Poor nutrition will destroy your body

In the long run, constantly starving the body will do more harm than good.

Its Slows Down Your Metabolism

If you deliberately starve your body by stopping the necessary fuel supply, you won’t create the need to burn fat in your body. Instead, you will create an incentive for the body to keep fat.

Thus, instead of burning excess fat, your body will go into “survival mode,” which means it will start storing everything, causing excess fat gain. That means it will start storing fat for the upcoming bad days.

In short, when you stop supplying your body with enough food, it slows down your metabolism. Moreover, it will keep fat, delay non-essential systems, and make you think more about food.

So, your body starts to slow down your metabolism and retain fat, taking you further away from your original goal.

You Will Soon Burning Lean Muscle

Your metabolism slows down, and your body starts to store fat. Then, instead of burning fat, your body will start burning muscles for energy.

When you are hungry, it will tend to burn fewer calories. Therefore, it will want less tissue because more tissue leads to more calories burned.

As you know, muscle tissue is a type of tissue that burns many calories. What’s more, it is not necessary for your existence. That is why your body will burn muscle before it burns fat.

The fact is that many studies show that the more muscle you have, the more calories you burn. In contrast, most weight loss results come from burning muscle instead of fat when you fast.

That means you’re doing the exact opposite of your original goal – burning muscle and storing fat.

You Will Fatter

4. Fasting will make you fatter than before

Fasting will make you fatter than before.

As we mentioned above, you can lose weight in the short term by starving yourself. However, as we explained, your extra fat is still there.

What’s worse is that when you eat regularly again, you will gain weight more quickly, making you fatter than before.

When you are starved, your metabolism will become slower. Calorie intake that used to be an average amount for you now seems too much to your body.

Then, when you go back to your old eating habits, you’ll end up with more calories than your body currently needs, causing you to gain fat.

Fasting Leads to Binge Eating

As a rule, when you do not get enough energy through meals, you will always think about food. However, you will deviate from your original goal by thinking about food while feeling hungry. That’s when you will find junk food.

It’s the reason you crave that cookie or chocolate bar, not because you’re impatient, but because hunger affects your health.

Worse, it will delay satiety, causing you to eat more than usual.

Other Negative Effects of Undereating

If you decide to continue taking in fewer calories than you need, you will jeopardize your health. When your body is starved, you are at increased risk for both mental and physical complications, including:

  • Hair loss
  • Heart rhythm abnormalities
  • Brittle fingernails
  • Slow heart rate
  • Abnormally low blood pressure
  • Loss of menstrual periods(for women)
  • Dizziness
  • Anemia
  • Trouble concentrating
  • Brittle bones
  • Swelling in your joints
  • Depression

If you’re not losing weight despite being in a calorie deficit, you should:

  • Contact your doctor for a physical exam and get your correct route.
  • Increase participation in activities to burn more calories
  • Get enough sleep, reduce stress levels as much as possible

Pro Tips

  • Give up the thought of reducing your diet or not eating at all.
  • Permit yourself to eat all kinds of food (because calories from any food are essential).
  • Do not discount the importance of satisfaction.
  • Learn to honor the hunger and fullness cues.
  • Participate in Cardio or HIIT exercises.
  • Do not eat less; just eat right!


Will eating less cause weight loss? The answer is yes, but only in the short term because there are many factors that affect our weight and overall health.

Therefore, instead of a nutritionally deficient diet, you should regularly apply a scientific diet and exercise to get in shape as desired. Hopefully, you will reach your goal soon. Thank you for reading!
