As for the 700-calorie diet results, they are individual for every person. In general, you are expected to lose 3-5 pounds a week, which is more than normally recommended. You are not advised to engage into this or any other very low-calorie diet without a medical doctor's supervision because of possible health risks.
For most people, 700 calories a day is not enough nutrients to provide us the proper macro and micronutrients we need to live a healthy life. For some extreme obesity related disease issues this might be a good option but it's important to talk to your doctor before trying to eat this little of calories.
It has everything to do with your metabolism. The higher your metabolism, the more fat your body burns. If you have a low metabolism, then of course the amount of fat your body burns is reduced. Skipping meals or not eating enough actually helps your body to become really good at storing fat.
Some people go on a very low-calorie diet for rapid weight loss, often consuming only 800 calories a day. This type of diet usually includes special foods such as shakes, bars, or soups to replace meals and for added vitamins. Very low-calorie diets can help a person achieve weight loss of up to 3 to 5 pounds per week.
An 800 calorie diet can be safe if it provides complete nutrition. It can also be unsafe when it lacks any essential nutrient. One main advantage of medical meal replacements is they provide everything needed for health while providing much lower calories.
This makes the fast days a little easier (!) and consuming up to 800 calories is still effective for weight loss. The advantage of the 5 2 diet is that you only need to eat less on 2 days a week, which can make the diet easier to follow in the longer term than struggling to eat less every day.
Diets of less than 800 calories can lead to numerous complications, according to Jampolis, including heart arrhythmias, which could lead to death. Extreme dieters are also at risk of dehydration, electrolyte imbalance, low blood pressure and high uric acid, which could lead to gout or kidney stones, she says.
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.
However, other studies show that while consuming 1,000 calories a day may result in significant weight loss, most people cannot sustain it and often experience significant weight regain . The reasons include regaining lost muscle mass and increased appetite. Also worth noting is that the human body can adapt.
Although every person's daily caloric intake is individual, based on their personal goals and needs, nutrition experts estimate that average daily consumption at each meal should be broken down as follows: 300 to 400 calories for breakfast, and 500 to 700 calories each for lunch and dinner.
You Might Get Malnutrition
Following an unbalanced 700 calorie diet for long enough can lead to malnutrition. You may not notice that your diet is unbalanced. For example, you may cut out calories from fats to meet your daily target.
One of the main reasons that undereating can lead to weight gain is because consuming too few calories can cause your resting metabolic rate to slow down. This means you may burn fewer calories throughout the day.
When you eat too few calories, e.g., a 900-calorie diet, it interrupts your metabolism. As stated above, your body thinks that you are starving, and thus, it signifies to your appetite hormones that something is wrong. They slow down your metabolism, which means that you will no longer be burning calories.
If you drastically slash calories and are eating a very low-calorie diet (Think: less than 1,000 calories for women and less than 1,200 calories for men), “starvation mode” can actually be starvation. Starvation from chronic undereating can be counterproductive to weight loss and dangerous to your health.
But if your calorie intake dips too low, says Lummus, your body could go into starvation mode. "Your body will start to store fat because it thinks it is not going to get anything," says Lummus. "You will be at a point where your body is kind of at a standstill."
Ordinarily, the body responds to reduced energy intake by burning fat reserves and consuming muscle and other tissues. Specifically, the body burns fat after first exhausting the contents of the digestive tract along with glycogen reserves stored in liver cells and after significant protein loss.
Effective At Weight Loss
If you need to shed pounds fast and don't expect the long-term result, the 1000 calorie meal plan may help you with that. As mentioned at the beginning of this article, this diet can help you lose 2-3 pounds (1-1.5 kg) a week, which is quite fast.
The 800-calorie rapid weight loss phase is safe for most individuals for up to 12 weeks, as long as you stick to our recommendations, drink plenty of water and use a multivitamin.
If you can eat 500 fewer calories every day, you should lose about a pound (450 g) a week. Always talk with your health care provider to determine a healthy weight for you before starting a weight-loss diet.
