For the op..
My mom had a heart attack about 10 months ago and when I was 21 so.. 11 years ago I had heart surgery.. my father has diabetes.. as I got into my late 20s and turning 30 i started becoming anxiety ridden and really worried about my health and those around me. As i researched health what I've found is that the health industry is a multi-billion dollar industry and everyone is trying to sell you somthing.. bc of this the amount of misinformation out there is unbelievable and there is a diet for everything literally.. what I found is "diets" don't work. I went as far as trying being vegan for about 8 months, what i found is most important is eating healthy whole foods.. staying away from processed food (thats where all the chemicals are). Most thing that come in a box or a bag and a pre-made pre cooked are terrible for you.. Number 2 exercising! start small and find a buddy to do it with. Me and my mom started going to the gym after her heart attack. She had gained slot of weight sitting around after the attack and the medicine they put you on. 3 months later she's shedding weight.
I HATE to say it but nothing is going to magically make you healthy your going to need to put in the work. You can lose some weight changing how you eat but there has to be action or reason for your body to use up it's stores of fat. Just eating less can actually make your body go into a fat storing mode thinking your going into a time of famine.. you need to train your body into burning fat to gain muscle. A lot of weight watchers and other programs where you lose 10lbs in a week all that is, is water weight. Stay away from a scale for the first 6 months take body measurements with a tape as your burning fat and gaining muscle your body size will change but the weight won't you may gain weight for a few months until your muscle gains slow.
Buy a gym membership this will hold you accountable and if your ashamed, have anxiety, or embarrassed about going, go somewhere like planet fitness at 5am nobody is there and those that are, are in the same boat and are more than willing to help..everyone in the gym is there for the same thing to make themselves better.. dedication goes so far, you gotta push yourself each day, tell yourself why your doing this. You want to be able to scout and get on that big buck a few miles back and be able to drag it out without falling down dead
