for over a month now I have been eating very healthy and going to the gym 5 nights a week. No sodas or junk food here, tons of water, tons of green tea, fresh produce, and I try to have protein with every single meal. I do cardio on the elliptical for 40 mins on a steady resistance of 3, and every few minute intervals the resistance changes to 4.5, which mimics me jogging up a steep hill.
So far I've lost 3 lbs, but I'm not just weighing myself, I am using a measuring tape to record my progress around my thighs, belly, and hips. Last week I lost nothing, but dropped an inch around my thighs and hips. There's a whole lot I have learned in the past month alone, and it wasn't an easy switch for me, I had a very awful diet before I started, and like OP, I only have 20lbs to lose. For me, it's not just about the weight loss though, it's about living a healthier lifestyle, becoming stronger than I ever have, and learning how to take care of my family better by eating better foods.
If anyone is interested, I have a whole lot more here in my journal I've recently started. It has meal plans, weekly weigh ins, and how I made a successful switch after many failed attempts in the past https://babyandbump.momtastic.com/wtt-journals/2280571-getting-fit-while-wtt-3-a.html
