Unwanted slippage

My weight has gone back up to 15st 2lb as of last Friday - not the direction in which I wanted to go.  I have been hitting the gym 5 times per week, so why should my weight go up?  I decided to do some more research over the weekend (for 'research' substitute 'watch YouTube videos').  I discovered some interesting stuff.

Cholesterol does not cause heart disease.

Eating saturated fat does not raise cholesterol.

Eating fat does not make you fat

Eating protein does not make you fat

Eating carbohydrates, especially refined carbohydrates, makes you fat.

The proof of the pudding is in the eating, or not eating in this case.  I've decided to cut out pasta, white bread, white rice and potatoes from my diet.  I'm also reducing the gym visits from 5 to 3 times per week.  The next couple of progress posts should confirm if I'm on track or lost somewhere down the wrong lane altogether.
