I'm a software developer with three young kids so I have approximately zero time to exercise. Look up the paleo (or even keto) diet. I lost about 20 lbs (which is all I wanted to lose, I now weigh 155 or so at 5'10") following a paleo diet about 80% of the time. You eat real food and never have to starve yourself.
I suggest something like this over a fad weight loss diet that you have to pay for as it's more of a lifestyle change, which means you'll be more likely to keep the weight off and be healthier overall in the long term.
