I've lost 75pound already and I have another 85 to go and its not easy.
Here's a couple of tips that work for me.
You should switch up and intensify your workout routine. Change your exercises every so often and shock your body. Take up a sport or an outdoor activity. I just started kayaking and I love it.
I plan my meals a 1-2 days before and I stick to it. I weigh and measure everything that I put in my mouth. I rarely have pasta or anything processed and everything is low sodium and no sugar added.
I also do alot of reading.about health, weight loss, food and beauty. It makes me want to try new things.
Hopefully my methods are helpful.
Good Luck, I know you'll reach your goal!
