I visit family in other states and I get comments like “I can’t believe you are so thin.” For context I am a healthy weight and I eat what I consider a reasonable diet. I sit and smile while I watch them drink soda and eat pure sugar and salt. I don’t care about your life choices but don’t act surprised by someone that’s a normal weight.
I live in Colorado, and one day I stepped on the scale and noticed that I hit a milestone, did the math and realized that per my BMI I just hit the obese line (check yours, it’s probably lower than you think).
I decided that I was not going to be the guy fucking up this map for my fellow Coloradans, so I started eating more vegetables, fewer carbs, and fewer calories overall, and lost 25 pounds.
So, I’d say peer pressure helps.
Get out and go for a hike. That will help immensely.
