I spend a lot of time here focusing on healthy eating and recipes, and I often include calorie counts for those who are interested in tracking their calories. But I don’t think I’ve ever talked about how eating too little can stall your weight loss efforts… and be downright dangerous. You might not equate the weight loss process with the possibility of eating too little: you should have the biggest deficit possible to lose the most weight, right?! WRONG.
A healthy deficit for losing weight is up to 1000 calories a day. A woman aiming to lose should never eat less than 1200 calories a day, and a man should stick to 1500 calories minimum. This is the safe recommended minimum to keep your body running well while still allowing you to lose weight. When I was actively losing, I rarely ate fewer than 1600 calories a day. And now that I’m basically in maintenance, I rarely eat fewer than 2,000 calories a day on average.
Even if you’re doing it unconsciously, eating too little can cause some serious health problems. If you’re eating fewer calories than your bare minimum, you probably aren’t getting the vitamins and minerals you need to keep your body functioning. Here are some signs you might be eating too little.
Are you tired all the time? Our bodies get energy from the calories in the food we eat, and we use that energy for basic and automatic bodily processes, like breathing, thinking and digestion. Eating too little can make you feel both physically and mentally exhausted, which can make each day feel harder and affect your productivity. It also affects your physical activity performance, preventing you from getting all the benefits from your workouts.
Weakened Immune System
A diet imbalance caused by eating too few calories can prevent your body from obtaining the nutrients you need to maintain a healthy immune system, which could cause you to get sick more often and cause each illness to last longer. This is especially important for those with already weakened immune systems like children and the elderly.
When you eat too little, your body has less food to process into stool, which can cause your stool to harden and be difficult or painful to expel. Constipation is generally thought to mean having fewer than three bowel movements per week and can indicate a slowed metabolic rate.
Skin can be more affected and damaged by inflammation and UV exposure if you don’t consume enough of the nutrient necessary to keep skin healthy. Vitamin E, B-3 and Niacin are all important vitamins for skin health.
Have you noticed and increase of hair in the drain after you shower, or in your brush? When you eat too little, the body prioritizes its functions, and you can begin to lose hair. The body doesn’t want to waste precious calories on maintaining hair growth and follicle health, so your hair will fall out at a higher than average rate.
The hypothalmus is in charge of telling your pituitary gland to produce reproductive hormones like estrogen and progesterone. The hypothalmus is very sensitive to changes in calorie intake and weight and if the balance of reproductive hormones isn’t spot on, it can cause menstruation to be thrown off or even stop, and when this happens, it can be difficult or impossible to get pregnant.
Irritability, Depression and Anxiety
Eating too few calories can seriously affect your mood in many different ways. When you don’t eat enough, your blood sugar can drop, causing hypoglycemia, the symptoms of which are irritability, sweating, anxiety and shakiness, etc. Have you seen those candy bar commercials where crabby people are handed a candy bar and told to eat? That could be you! Not eating enough can also cause you to feel more emotionally sensitive and a side effect of vitamin D deficiency is depression. Anxiety can also be caused by not getting enough omega-3 fatty acids, known to decrease anxiety.
Having trouble falling asleep because you’re hungry, or waking up in the middle of the night hungry is a pretty obvious sign you’re not eating enough. But it can also lead to not spending enough time in deep sleep. Sleep deprivation can lead to insulin resistance and weight gain, which is the opposite of what you want when you’re trying to lose weight.
Your body needs a certain number of calories to complete all of its basic functions, and that includes keeping up your core temperature. Studies have also shown that a restrictive diet can cause a decrease in T3 thyroid hormones, which helps maintain body temperature, along with other functions.Constant HungerIf you’re always hungry, it should be pretty obvious that you’re not eating enough. But many people force themselves to ignore hunger signs in order to lose weight. Being a little hungry sometimes is okay, but low calorie intake can cause a number of problems in the hunger department, like an increase in cortisol, which is the hormone that can increase belly fat. Spending too much time hungry can also increase cravings and cause you to binge, which is the opposite of what you want when you’re trying to lose weight.
