Scott is right on, to lose weight the only thing to do is to eat less. Improving food quality is always nice too but there’s got to be fewer calories in. In my experience this is incredibly difficult without a food tracker like My Fitness Pal, which works wonders if you stick to it.
For training, I find it’s difficult to do long aerobic work and a calorie deficit at the same time. The long workouts stimulate hunger and it’s actually not that difficult to burn 1500 calories then eat 2000 calories back and end up at a net negative. “It was such a hard workout so I’m having a double cheeseburger and fries, and hey a beer or two as well.” It’s tough to do two-three hours in the hills then refuel with a salad with light dressing, both in terms of your body recovering day-to-day but also the mental aspect of feeling satiated.
So my advice would be to focus your training on strength work. Gyms are or should be closed due to the virus but figure something out. Strength seems to work better for most people in a calorie deficit, but recognize that you also won’t have as fast of gains as you would when eating more.
But the diet is the main thing. And again, I know hardly anyone who’s lost weight without a tracking program like My Fitness Pal and I know a ton of people (myself included) who have used it successfully.
