how to maintain current weight after weight loss (i want to stop dropping pounds now but cant)?
Q: since august ive lost 14 pounds and currently weigh about 110. the changes were mostly made in my diet, i stopped eating all junk food, drank only water, ate nothing after 730, ate a lot helathier. i also swim 2 hours each day, but did this before the wieght loss. im finally at a weight im happy with. i dont see fat anymore. but now i cant stop losing weight. i guess ive trained myself to think that certain food is bad and cant eat it. im worried about being fat again. but i really want to stop losing weight and maintain my current weight. i just dont know how to do this. my friend was anorexic for a few yrs (i am def NOT anorexic nnor was i ever) and when she went to treatment she gained a TON of weight. i would even say shes overweight now. i dont want this to happen to me. so what should i do? how much should i be eating to maintain my weight. this is an example of what im eating now:breakfast: bowl of multi grain cheerioslunch: healthy choice vegetable soup or a turkey sandwich, piece of fruit (10:30 because i have 3rd period lunch at school =( )dinner: (usually at 3:00 due to swimming schedule): something like baked chicken and broccoli or pasta and salad or basically whatever my mom makes but its usually helathyafter pratice snack: (7:30) : fruitwhat should i be eating to stop dropping weight?!
A: Well you should not stop eating healthy that’s for sure. maybe add some exta stuff to your meals…like some toast with breakfast or change it up and eat some eggs. and eat a little bit more at lunch. eat a snadwhich and some fruit and maybe add in some chips. Adding a couple of things that are higher in fat throughout the day will not make you fat as long as you keep it in proportion and stay active. I would say to decrease your activity level too. maybe add some desert in there. If you keep having this problem I would suggest going to your doctor.In order to maintain your weight you have to east the same amount you burn and not burn more than your eating. If you eat more then you burn then you will gain weight.
