We all know that calories matter a lot when it pertains to weight loss. As long as you eat fewer calories than you burn, you must lose weight. The logic is sound for a lot of healthy adults, but we can also take that logic too far. In the case of healthy, sustainable weight loss, a lot more restriction doesn’t always cause better weight loss. In fact, frequently eating too few calories can put you at risk of malnutrition, resulting in unhealthy weight loss and nutrient deficiencies.
We must goal for a minimum daily calorie goal of 1,200 calories per day for women and 1,500 calories per day for men. according to recommendations from the national Institutes of Health.
What really happens when you make yourself skip meals?
The difference between fasting and chronically undereating (which can cause starvation) is a matter of duration. Fasting is frequently practiced on a timescale of several hours, but while the term has earned itself a bad track record from notorious fasting or “detox” diets (think: cayenne pepper diet), fasting for weight loss can be safe. Our bodies were actually created to manage short-term fasts, like when we don’t eat for eight hours during sleep. We also go anywhere from 4–8 hours without eating when we skip meals during life’s busier moments.
On the other hand, going without food for several days or eating less than the calorie minimum for weeks to months puts you at risk of malnutrition. As well-nourished individuals, we do carry enough stored fuel to meet our needs for 1–3 months in the form of muscle tissue and fat. However, our body can only store 1–2 days’ worth of glycogen (the body’s carbohydrate stores), which, if not replenished, is swiftly used up to maintain blood sugar.

After several days of undereating, the body switches to energy-conservation mode, indicating your metabolism slows way down, making you feel worn out and edgy. As carbohydrate stores run low, protein and fat become the dominant sources of fuel. After 48 hours without food, your body runs out of glycogen to power the two organs that need it the most: red blood cells and the brain. While glucose is the only fuel blood cells can run on, the brain will begin to adapt to power itself with ketone bodies made from fat. To meet basic energy needs, your body ramps up breakdown of muscles and organs in addition to fat.
Slower metabolism and lousy side effects.With too few calories on board to power you through your daily activities, your body learns to live on less by substantially slowing your metabolism. short term, you may feel sluggish, irritable and apathetic. once you stop undereating, it takes awhile before your body to recover and your metabolism to rev back up.
Loss of useful muscles and organs. just because you’ve adapted to using ketone bodies doesn’t indicate your body won’t need glucose at all. A minimum blood glucose level need to be maintained to keep you alive so your body continues to break down muscles and organs. It’s a major problem in the long run, because your body doesn’t distinguish between vital tissues (think: heart, kidney, blood cells) and less vital tissues (think: skeletal muscle). Over time, this breakdown weakens and damages your crucial organs.
Higher risk for nutrient deficiencies. eating very few calories will also decrease the variety of foods you can eat, boosting your risk for nutrient deficiency. The type of nutrient deficiency that can occur depends on the food(s) that are being restricted. While not everyone who chronically undereats can automatically be diagnosed with an eating disorder, anorexia gives insight on the types of nutrient deficiencies that are likely to occur from prolonged starvation. This includes but isn’t limited to deficiencies in calcium, iron, zinc, vitamin D and the B vitamins, in addition to hazardous electrolyte imbalances and protein malnutrition.
Every body is different, so it’s crucial to experiment and see what works best for you. just know that undereating is not a good long-term option for living a healthy life or achieving or maintaining weight loss.
