Not seeing any change in weight could be the result of your increasing weight from water, muscle, or food storage - even while simultaneously losing body fat, causing your weight to stabilize. Even more disheartening than not losing weight, is the appearance of potential weight gain.
One of the main reasons why burning calories through exercise may still not result in weight loss is due to overexertion, or inflammation of your body. If you exercise too hard on a daily basis, there is an excess of inflammation in your body. All the added up inflammation makes you gain more weight than lose.
Muscle is denser than fat.
While one pound of fat weighs the same as one pound of muscle, muscle occupies about 18 percent less space. In addition, muscle burns calories while fat stores them. So, if your weight isn't decreasing but your clothes are starting to fit more loosely, you may be building muscle.
So, if you're eating 1,200 calories and not losing weight, it could be that your body is really struggling to function on so little fuel and your metabolism is not functioning well enough to respond to a deficit in the way you'd like.
This phenomenon is called “starvation mode,” and while your body isn't actually starving, it will naturally hold onto whatever calories it receives in an effort to help you maintain your energy balance.
Glycogen or sugar that your muscle cells convert to glucose is the energy source for your muscles. When you exercise regularly, your body stores more glycogen to fuel that exercise. Stored in water, glycogen has to bind with water as part of the process to fuel the muscle. That water adds a small amount of weight, too.
If you're not losing weight in a calorie deficit you may need to adjust your stress levels, diet, and sleep patterns. Other reasons for weight gain during a calorie deficit are hormonal changes, aging, and other health conditions.
People may try this diet to control their food intake and lose weight. Some research suggests that the average female can limit their daily caloric intake to 1,500 calories or less to drop 1 pound per week. The average male may consume up to 2,000 calories a day to lose the same amount of weight.
Most people need significantly more than 1,200 calories a day. Therefore, individuals who cut their daily intake to 1,200 calories can expect to lose some weight.
Eating just 1,500 calories per day while following a regular exercise program will likely lead to a healthy weight loss. However, 1,500 calories per day is too low for some regular exercisers, especially those trying to maintain or gain weight.
A slow metabolism has many symptoms, and you're likely to have one if you find it difficult to lose weight and easy to gain weight. Other symptoms include fatigue, poor digestion, constipation, low mood, and a colder than average body temperature. All of these are caused by the lower production of energy and heat.
When you fast for shorter durations, your body doesn't have enough time to go into ketosis. This means it won't burn stored fat, and there won't be significant weight loss. As one study concluded, a fasting window of 18-19 hours is more effective in terms of weight loss than those between 12-17 hours [11].
You've Gained Muscle Mass
If you're exercising regularly and doing a mix of cardio and strength training, it's very likely your body composition (ratio of muscle to fat) is changing for the better. If you're gaining muscle while losing fat, the scale may not show any weight change.
Without understanding your caloric intake, walking 10,000 steps or more might not cause enough meaningful fat loss. However, there are enormous health benefits to increasing your activity level through moderate exercises like walking.
Muscle helps keep up the rate at which you burn calories (metabolism). So as you lose weight, your metabolism declines, causing you to burn fewer calories than you did at your heavier weight. Your slower metabolism will slow your weight loss, even if you eat the same number of calories that helped you lose weight.
The 1200-calorie diet is geared toward women. Men's bodies require a higher caloric intake. This means that a typical woman can eat between 1200 and 1500 calories a day to lose weight. A typical male body needs about 1500 to 1800 calories daily to lose weight.
Mental health
Intense feelings of stress, anxiety, depression, and other forms of mental health decline can play a major role in weight loss success. It has been observed that even people who record success in weight loss may lose all their progress when they experience mental health issues.
However, calorie intake should not fall below 1,200 a day in women or 1,500 a day in men, except under the supervision of a health professional. Eating too few calories can endanger your health by depriving you of needed nutrients.
