You can do it, and I'm sure you'll do it
Just my 2 cents..setup monthly targets not by the amount of weight you'd lose rather by the amount of exercise you'll do & the no. of calories you'll take in. I'm sharing this because I did the same when I started and got frustrated when I didn't see the scale moving the way I wanted...I setup the goals on how much I'd lose every week & then every month..unfortunately the weight loss doesn't happens as you think or assume on the plain 3500 calories burnt theory..your body may exhibit slow losses during some months, plateaus and then you may feel like giving up...if you change it to the other way i.e. on the basis of exercises & calories you'll do & take you'll have better chances to achieve your goals on scale too.
I'm on a plateau currently..and I've learnt that the best thing to do is to keep counting your exercise minutes and calories and ensure that you do meet these targets..this way you keep moving even though you may feel little annoyed when you don't see the scale moving, you'd still not give up.
I have complete control over my body. What I eat and what I do reflect that. Nobody can stop my progress. I will continue my progress until my goals are met. Then from there I will need to achieve new goals to keep the forward progression of my mind, body, and soul. I motivate myself every day to work out, eat healthy, and live my life to the fullest
