No, it doesn't. Making yourself sick after eating can only get rid of about half of what was eaten previously, and usually much less. That's because the digestive process begins as soon as you put the food in your mouth, being broken down by the enzymes in saliva and the teeth through chewing
The only way to lose weight is to burn up more calories than you're consuming, so the body has to raid its fat storage for an energy supply.
If you're throwing up a lot, that sounds to me like you've developed bulimia nervosa. A very serious and sometimes fatal eating disorder!
Behavioral signs of bulimia include:-
- binge eating (eating a lot of food all in one go, generally calorie, sugar and fat laden foods like chocolate, crisps or biscuits). What makes it a binge is that once the individual has started, it's very difficult for them to stop. It's also possible that people may binge on whatever foods are available at the time.
- purging in some way after binge eating (the individual getting rid of the food they've eaten) such as fasting (starving yourself) self-induced vomiting (forcing themselves to be sick), abusing medications like diet pills, laxatives, diuretics or enemas, or over exercising.
- thoughts about food preoccupying the mind. An individual with bulimia may plan binge episodes and shop for foods specifically to binge on, and may go to different shops to prevent suspicion. For example, they may go to one shop for a load of chocolate, then to a second shop for a lot of biscuits, and a third for lots of crisps.
- being unusually secret about eating
- mood swings
- feeling anxious and tense
- distorted perception of weight and body image
- feeling like there is a loss of control over eating
- feelings of guilt and shame after a binge episode
- can also be associated with other problems like self-harm, alcoholism, low self-esteem and depression
Physical signs of bulimia are:-
- Vomiting, especially after eating
- Excessive exercising
- Misuse of laxatives and diuretics
- Disappearing soon after eating, typically to the bathroom to vomit
- Fatigue/lethargy
- Bloating
- Constipation
- Abdominal pain
- Swelling of the hands and feet
- (In girls and women) amenorrhea (the menstrual cycle stops, or becomes irregular, as a result of the body going into survival mode)
- Enlarged salivary glands
- Calluses on the backs of the hands, fingers and knuckles, from forcing them down the throat to induce vomiting
- Electrolyte abnormalities/ imbalances
- Problems with the digestive system organs
- Regular changes in weight
I strongly recommend that you see a doctor immediately for help, as throwing up as a weight loss method is ineffective and very harmful. Your GP can help, and they may also send you to a psychiatrist (a doctor who specializes in treating mental health problems, which eating disorders - such as bulimia - classes as. A doctor can also determine if you actually are overweight or not. It's possible that people may think that they're fat, when really, they're not.
Hope this helps.
