Constant hunger
Being hungry all the time is one of the obvious signs that you're not eating enough food. If your calorie intake declines, your body will send signals that forces you to eat in order to provide the calories the body needs to function. So, do not wait until you are famished before you eat.
You crave sugar
Low blood sugar, boredom and fatigue are the most common reasons for craving sugar. But, if these are not the reasons for your cravings, you are not getting enough quality food nutrients such as protein, healthy fats and fibre.
You feel always exhausted
Undereating affects your energy levels, and mood. You will feel lazy and tired most of the time as well as experience mood swings and this is the result of not eating enough food.
Your clothes don't fit you anymore
If your favourite clothes are not fitting you anymore, it is time to evaluate your food choices!
Feeling cold
If you constantly feel cold, not eating enough food could be the cause. Your body needs to burn a certain number of calories in order to create heat and maintain a healthy, comfortable body temperature.
Constipation
Constipation refers to bowel movements that are infrequent or hard to pass. Dieting and eating too little food can cause constipation due to a slowed metabolic rate.
Hair loss
It's normal to lose several strands of hair daily. However, if you're noticing an increased amount of hair accumulating in your hairbrush, it may be a sign that you're not eating enough.
