One of the worst things you can do is tell people you are on a diet or getting fit etc. because they will sub-consciously undermine you.
And to drive the point home yet again , you should lose weight and lift because most of your other problems with women will just go away. You hit some magic ratio of chest to waist and women find you attractive and approach you. Your new problem being how to respond when standing in the coffee line some girl says you look like a movie star because you are wearing sunglasses, or you are getting a cavity filled at the dentist and the assistant leans in and tells you; "you have beautiful eyes"
But back to why you should keep it to yourself that you are on a journey of self-improvement .
The two people I told are no longer my friends. They were both close friends whom I had known for a long time. I told them with the best intentions. Things that I discovered in losing weight and eating healthy and since they both had problems there, i thought they would be interested. I was not a pest or mean or nagging. I was nice. After I told them both started to undermine me in the exact way that I told them what I was doing to improve.
One friend it was McDonalds. I told them I avoid it and don't eat there it was garbage. Magically every time was with him he would steer towards McDonalds " Oh they have summer specials on!". Or give me coupons they had mailed him and even deliver it to my house because " he stopped on the way" Both he had never done before. He got really childish and pissy when I pushed back or tried to deek out of eating till finally I felt i was more important that his feelings and the friendship pretty dissolved
Second friend it was same thing. Suddenly he was bringing me all this junk food "To celebrate" "Movie night" and the final straw was bringing an armload of family sized bags of chips because "Lay's has all these new flavours !!" He too acted like a spoiled 4 year old when I was not excited and refused to eat that shit.
I believe it was their ego that made them do this, all sub-consciously. I was making actual improvement to my life and they could not. So this made them feel uncomfortable,that they were failures and I was better. The easiest thing was to undermine me and my efforts.
Everyone else that I lied too of why I can't eat McDonalds when they suggest it are still my friends . I make up a story that I am on medication for cholesterol and it gives me diarrhea, if they keep insisting , I give a detailed description of the diarrhea. That usually ends their insisting.
So it can't be my imagination that "I'm on a diet" is worse to a friendship than " Let me tell you about the shit that flies out of my ass and sticks to the toilet bowl so hard that you have to flush four times "
So this is your journey alone. Get fit , lift and then your problem will be being on your toes to respond to the girl who just came on to you and clearing your schedule to take her home and fuck her.
