In our society it seems like everyone is stressed to be as thin as the models on the cover of Vogue and Men’s Health. Although this is the case, hardly anyone is able to lose “enough” weight in order to look like these “normal” people. The media feeds us images of people that have been airbrushed to “perfection” and people who’s job it is to workout and eat as little as possible. This is not the life anyone should live!
When a person significantly decreases their caloric intake their body tries to fight back. Although it may be a little counterintuitive the body actually slows down your metabolism when you start eating a significantly smaller amount of calories. If you begin cutting calories without paying attention to any of your nutritional needs you could do severe damage to your body!
There was a study done, in 1944, called the Minnesota Starvation Experiment:
- 36 men were only allowed to eat 1800 calories a day for 6 months
- These men were not given balanced diets, and not near enough calories to sustain their body weight. After 6 months they lost 25% of their body weight.
This is what happened to them (because of the lack of calories)
- the men became increasingly irritable, impatient
- had a decreased tolerance for cold temperature
- suffered from tiredness, muscle soreness, hair loss, reduced coordination, and ringing in their ears
- they no longer enjoyed any of their favorite activities
- lost interest in women and dating
- had to drop out of their university classes because they did not have the attention span to pay attention in class
- and they complained that they could only ever think about food – this was later termed semi-starvation neurosis
Semi-starvation neurosis happens to everyone that significantly decreases
their calories below what they require. People will dream about, think about, and constantly talk about food. These people have a hard time enjoying their favorite activities because they can’t think about anything but food. Even when they are at a family gathering they can’t focus on conversing with friends and family because food is constantly haunting their thoughts.
In the Minnesota Starvation experiment after the testing period, the men were given a 3 month re-feeding period. The men found this to be the hardest part of the study; they could never seem to get full! No matter how much they ate, they constantly wanted more food. The men were warned to be careful and try not to eat too much, but most of the men went out and gorged on food and had to get their stomachs pumped. The men eventually adopted their normal eating behaviors again, but it took them almost 2 years to totally recover the muscle tone that they lost, and their sex drive and strength also did not recover very quickly.
This does not just apply to these men. People who severely reduced their calories will feel the same way these men did after a short period of time. This study should give you motivation to NOT reduce your calories a significant amount; just look at what happened to those men!!

Studies have shown that when a person decreases their caloric intake to under 1,000 calories per day they send their body into “starvation mode” and your body will slow down the metabolism in order for it to hold on to as much fat as it can, for as long as it can. Your body does not differentiate between self-induced starvation and genuine starvation, it just knows you are getting enough food.
Here are some other side effects of cutting too many calories
- headaches, weakness, and light headedness
- reduced concentration levels
- inability to lose weight
- reduced sex drive
- loss of muscle mass
- loss of muscle strength
- reduced mineral bone density
- hormonal changes
- in women – menstrual irregularities (possibly infertility)
- slower reflexes
- decreased resistance to infection
Instead of reducing calories to lose weight or “be more healthy” try these things:
- eat the proper amount of calories for your age, body, and exercise level
- listen to your body, if it is hungry, give it some food. Of course it is not a bad thing to eat a little less, but make sure you listen to when your body is hungry
- Eating fruits and vegetables throughout the day will help you reduce your overall caloric intake, but will also keep in the good nutrition that your body needs
- move around! Do some kind of exercise every day, it will keep you strong and healthy
