Why is it that I can never lose weight in my thighs?!

The easiest answer would be to say its just your genetics. your dna predisposes your body to retain thigh fat for as long as it can. But i would only say that is true if your intire upper body had no fatty areas what so ever and was perfectly defined.

or i could say its because all your doing is aerobic exercise. Thats not good enough. weight training is so much more effective at fat loss then aerobic ex especially if paired with a low cal diet.

People say spot reducing isnt possible but there is such limited research on the human bodys response to unconventional training methods.

one theory goes like this.
blood carries fat stores from muscles to the liver to be converted to fuel for muscles, so if you wanted to encourage your body to take fat stores from your thighs then pairing aerobic exercise such as jogging (dont walk unless ur a granny) with a few high rep (12-15) squats, lunges, deadlifts or even %100 effort up hill sprints will increase blood flow to your thighs and encourage fat loss in that area.

but overall,an optimum exercise routine would be to do full body resistance training for 30mins to 40 mins and 20 mins of jogging every 2nd day. the days in between you should do cardio for no mroe tha 1 hr and 2 days a week (sat sun) rest.

and then theres diet but thats a long story

when you say 'drastically' how many cals per day were you on, <800? ...

you give no stats to determine even a rough amount of calories to recommend you to eat.

when cutting calories for weight loss, simply deduct 15-20% off your maintenance total. this may only yield a 0.5-1kg loss in weight each week but over 6 months you could easily shed around 20kg and hopefully knock several inches off your waistline, and hips.

the most important thing is WHAT you eat... all calories are not the same, even ones people think are good for them. simply by cutting out as many things with added sugar in them will kick start any good diet plan. then look to reduce or limit all the processed foods in your diet, two servings per day is a good amount, any more will aid fat storage. eat fats, they do not make you fat, if you plan out your diet to incorporate a decent amount each day, typically around 30% of your daily cals!

I would absolutely guarantee your diet is at fault.

sorry- There is no such thing as "spot specific weight lose".- You can only do exercises that may target that region-and also burns fat in other areas of the body.
"Keyboard Warrior" said it best to change up your routine.- Push your body to the max( if healthy enough-which you are) changing routines as time progresses.

Some women just have thick thighs. I am petite 102 pounds and 5 ft. 2 in. and have thick thighs as well. I eat right and exercise but my thighs never shrink. My boyfriend says that he finds them sexy so I am not self conscious about them at all.

You have to change up your old routine. Your body eventually gets use to it. And you can't spot reduce...the fat comes off wherever it will. Thigh's for you, maybe the last thing to go.

sometimes your body type and bone structure just doesn't co-operate with your wishes~~

Heredity also plays a BIG part!

That's just where your body natually gains weight. It may be that no matter how hard you work, they will never get as small as you would like

Don't worry ! There's nothing better than a solid thigh around your neck.You are probably from Russian shot putter stock

jogging is an excellent exercise because it let you lose weight
evenly throughout your whole body. If you want to lose weight in
specific areas, you should target them with exercises. If they are
your problem areas, they will be very difficult to tone. You will have
to work double on them. The best approach is this:
1. Lower/control your daily calorie intake (control for normal
weight, lower for overweight).
2. Run/jog to lower your overall body fat percentage.
3. Target your problem areas with exercises.
