You might find you can tolerate chips (assuming you really want the chips) better if they are actually deep fried, it is said by some that the fat slows down the absorption rate, not certain myself, but if deep fried make sure its in a fat that does not break down at high temps, my local chippie uses beef fat and although I have chips very infrequently when I do it does not affect me too much, unlike boiled or mashed potatoes. I usually low carb though.
Low carb or otherwise, the best way to oose weight is still to reduce calorie intake so you have around a 500cal daily defecit, couple that with exercise and you should lose the weight you want. I managed to shed 30lb in 8months so worked for me.
