20 pounds over the course of 5 months is a good pace. I thought I'd be a lot skinnier than I am. The results haven't shown in the mirror as much as they have on the scale.
I completely understand, I went from 198 to 164 at my own pace over about 2 years or so and I can only now really just tell the difference. In alot of my area's like my back and around the love handles it looks almost the exact same as it did when I was at 198.
However my face looks about the same to me, but to others' that had not seen me in since then usually are like "man you really lost that weight" or " your the same size you were in high school" Honestly when I was gaining weigh I didn't even really how puffy in the face I was getting, my sister who is always honesty was like you getting fat, "looks like you been stung by bee's"
I was like oh hell nah, im not gonna be one of those people.
But yeah you might just not have the facial structure to have a dope jawline regardless of how much weight you lose. I'm in that boat, a nikka just got a round face
Keep up the hustle though, the next 10 or so pounds are probably were you will actually see the most difference in your body.
