How can i lose weight by the end of July/Beggining of August?
I want to lose weight, i know i am overweight by alot. I am 14 and i am over 200lbs i want to lose some weight by the end of july/begging of august because i am going to see my father then. But he is planning to take me to some water parks and i dont wanna look huge, and i dont wanna be the fat girl in the bathing suit. I know you have to eat healthy and exercise drink lots of water to burn off calories and blah blah blah, i try but i end up eatting unhealthy stuff and i always say ill go for a run or exercise tomorrow but never do. I just dont want to be the fat girl anymore, i deal with people saying stuff to me at school and i am really getting sick of it, i want to go back to school thinner then i am, and i want to be really thin for my Grade 9 Grad in a years time. so please if you have any weight loss methods please let me know. im begging you. i NEED to lose this extra fat!
*Today, i ate maybe 650 calories, and i still have to eat supper and i went for a 20 minute walk/jog.
My very first suggestion since you have a hard time with the motivation and will-power factor is to find a friend or family member willing to participate with you. You could even make it a competition with mini-goals.
You will need to set a long-term weight loss goal, so find out what your healthy weight range is based on age and height. Then you need to decide when you (realistically) want to be that weight. I think a goo time frame would probably be the end of your 9th grade year (since that’s when you want to take your pic, right?) and that gives you plenty of time. After you set that goal, you’ll want to make short term goals to help you reach your long-term goal (run a mile, lose 15 lbs by July 4, feel good in a swim suit by August, etc), and celebrate each milestone you set for yourself so you have something to look forward to in the meantime. Take pictures and do measurements (weight, body fat, BMI, chest/waist/hip) and keep an accurate record to mark your progress.
After you set your goals tell people close to you that can be supportive when you want to “Cheat.” Pick a day that you want every week to do your measurements and do them immediately after you wake up in the morning, after you pee, but before you eat or drink. You don’t need to be a runner to lose weight. There’s sooo much more you can do: sports, walking, playing with your younger cousins, riding a bike, swimming, playing Wii, yoga, strength training, dancing, roller skating and the list goes on and on and on… you can even lose weight by cleaning your house.

Each day, keep track of your caloric intake and activity so that you can look back with pride on the effort you have made. Be sure that you do not dip too low in your food intake because you do not want your body to go into starvation mode. Somewhere around 1700-1800 cals every day should be sufficient if you are exercising, but you should also talk to your doctor or a nutritionist for specific nutritional needs.
In the first few weeks you’ll see dramatic changes in numbers, and probably feel a large difference, but maybe a month or so in everything will slow down and become a little more subtle, so don’t get discouraged just because you didn’t lose as much weight. As you lose weight, it becomes harder to lose even a single pound purely because you are not burning as many calories during each exercise. As you become more fit, you can increase your exercise intensity and time and that will help you increase your calorie deficit.
If you slip up and binge one day DO NOT freak out and give up. One day will not ruin your diet — trust me, I have done it sooo many times. Every once in a while you need to treat yourself, but do it withing reason — so a 1 cupcake, or 1/2 cup of ice cream, 1 slice of pizza (2 if its veggie), etc.
I hope this helps, and I wish you the best of luck!
