I have read that already and as a man of science, it's frankly a mess and doesn't really prove or disprove anything. Anything that qualifies health in terms of BMI is an instant give away as to its lack of usefulness. Whereas comparing a similar study with folks who eat 5 times a day and exercise, and including more relevant indicators like body fat would be a far better study.
Right now I stick with what works. 2 meals + exercise + testosterone = forget about it! It's not going to work and if your body doesn't have enough fuel you struggle to do your actual best with exercise. On Mondays, Wednesdays and Saturday's I do an at home work out and Taekwon-do. I couldn't coordinate having enough fuel to handle that + work. But spacing out meals to stay constantly fueled does work. I've done the 2 meals a day while cycling to and from work and I got fat. I eat 5 times a day now and workout and I've lost 20lbs. Maybe that study worked with those individuals based purely on BMI but we've already established how BMI is bogus anyway.
If one wants to be thin and healthy, one needs to care just as much about exercise as they do about food. In order to get the best out of exercise, small regular meals works best. It means you eat, wait an hour, exercise, then eat an hour or less after. And the results when people do that are always the preferable and more ultimately healthy results. When they release a study where non exercising individuals eat 2 meals a day and get better or similar results than exercising indivuals get on small meals throughout the day, maybe I'll care, but any report that uses BMI as an indicator and doesn't focus on exercise being as equally important as food is an instant red flag for me.
