Need help to loose weight!?

No nasty comments please but I need to start loosing weight! I know I’m not obese but the weight, especially in my boobs causes a lot of back and shoulder pain. I seem to gain weight like crazy but despite dieting (paleo, vegetarian etc), exercise, calorie counting and otc weight loss supplements I’m unable to shift any of the weight. I currently weigh 70kg and I also need to keep my weight down for my chosen career.

Anyone able to help?

I’m wanting to loose around 10kg - 15kg particularly the boobs, muffin top and thighs. Help please, I’m completely at a loss.

Also I can’t go through a breast reduction at this point in time as University is currently very hands on skills etc.

Thank you!
