I tried lifting heavier but it didn't agree with me. Too much muscle soreness and it wasn't really resulting in any weight loss. Now days I try to do calisthenics three times a week. I've been using a local park that has some outdoor gym equipment and bars. When I use gym equipment I just try to do 2-3 sets, 12-20 reps, and get within a few reps to failure. Sometimes, on a higher intensity day, I will add drop sets and progressively reduce the weight.
Low intensity cardio for several hours per week, at a relatively high volume, on the other hand, seems to have helped me to lose more visceral fat.
I'll be using my Garmin to track how much an impact the low intensity cardio has. I went out to the park this morning and did some body weight exercises and some walking for about 45 minutes, and the Body Battery only fell a few points (59-44). So I could probably add more volume of cardio on a better day (I didn't sleep so well last night). The big limitation is probably my knees. If I do too much volume (especially walking), I get some pain around my knee, maybe the IT band or bursitis (it's usually my left knee). That's why ideally, I prefer doing mostly air walker, an elliptical, or a bike.
I think a relatively lower carb, lower fat approach is probably best for weight loss. Lots of non-starchy vegetables. I like palm hearts, they have very few calories and are mostly fiber and water, and they have a little bit of a crunch to them.
What seems to work best for me is 1/4 beans or some other higher-protein food, 1/4 whole grains or starchy root vegetables, and 1/2 vegetables and fruit. And a small amount of nuts, seeds, or a small amount of avocado (about 10-20 grams a day or so, no more... because they are relatively calorie dense and easy to overeat). Also, avoiding added oil or sugar. Bread and pasta are probably best avoided altogether if you are serious about weight loss. They might be OK once you reach your target weight, but they are usually more calorie dense, even the whole grain types.
