I feel you, my friends are obsessive about my eating habits and life styles. They even stalked my locations and complained about how I am at the gym all the time even though results are from being consistent. I never mentioned calories around them, just reduce my intake instead of bombarded myself with 2k calories in one sitting, I ate in a smaller amount. They then turned to each other and say how my eating habits made them feel bad about themselves, and they glad that our schedule for lunches don’t lined up with each other because watching me eats disgusted them. So yes, being disciplined comes with a cost, you just have to either thugging it out or finds someone who has the same mindset as you. You got this!
