Diet and exercise are tried and true. Eat wholesome food and exercise everyday. Exercise doesn’t have to be crazy either. I tried keto and lost 10 lbs in a week, it was all water weight. Not on it now but it was a great eye opener to learn how much crap food is out there. Get educated on your food and start a basic exercise routine. The secret is once you start, your confidence builds and you start feeling and looking better. You have to learn self control with your eating and move your body.
