When you are eating 1,200 calories a day, you should lose weight. If you are continuing to gain weight on this type of low-calorie diet, you must look at other possible causes for putting on the excess weight. You may be suffering from a medical condition or not eating as low a number of calories as you think. Speak to your doctor about any weight gain experienced during a low-calorie diet.
Certain medications and medical conditions are associated with weight gain. You may continue to put on weight even if you follow a 1,200-calorie diet. Drugs that alter the metabolism such as insulin can make you gain weight. Other medications associated with weight gain include anxiety medications, depression drugs, corticosteroids, calcium channel blockers and beta blockers. Medical conditions that can cause unexpected weight gain include thyroid disease and metabolic disorders.
Not getting enough sleep or sleeping too much may be related to unwanted weight gain. According to a 2010 study published in the journal “Sleep,” researchers found that limited or excessive amounts of sleep are more likely to cause weight gain. The ideal amount of time to sleep as a way to prevent weight gain is six to eight hours each night.
The product you use to lose weight also may be causing your weight gain on the low-calorie diet. According to a 2011 Purdue University study published by the American Psychological Association, synthetic fat substitutes can attribute to obesity and weight gain. The study found that the fat product interrupted the regulation of food intake, and rats used in the study gained more weight than the control group.
The time of day you eat also can affect whether you are gaining weight on your diet. According to a 2005 study presented at the American College of Sports Medicine Annual Meeting, late-night eating contributed to weight gain in college students. Subjects who ate during the hours of 8 p.m. to 4 a.m. gained an average of 1.1 pounds after 12 weeks.
