From the ladies' locker room: Newsflash. Dad bods NOT sexy. Chubby belly is just that, chubby belly. Skinny fat is sickly looking. As a woman I figure I work hard and make lifestyle choices that allow me to have a better figure than most women half my age or younger. I am not going to be seen with someone who doesn't similarly value taking care of their body.
The best way to get a good physique is to work out regularly (some resistance work, some cardio, best is HIIT training) and at the same time reduce carbs from your diet and focus on fiber and protein. I almost never eat the following: Breads, pastas, dairy, candy, sweets, potatoes, soda, fast food, junk food. I drink primarily water, tea, coffee, Kombucha, and wine. I swim a little or do a mile of interval training or walk several miles. Some people like to cycle. I never got into that but it's a great workout. Even some yoga or basic stretching is good. Anything helps.
Over time this type of lifestyle will bring your body into shape and keep it that way. My guy is 6'3". When we started dating he weighed 242lbs. He's now at 210lbs., due to the dietary changes because he's largely adopted my way of eating. He looks better, feels better, his snoring is better, his sleep quality is better. And he hasn't increased his workout regimen.
Your metabolism will do a great deal of the work for you if you'll modify your eating habits. But it isn't a temporary thing folks. It's discipline and it's lifestyle.
Make no mistake, we eat lots of indulgent things. Various cheeses, eggs any which way, meats, steak, etc., and I make wonderful veggies reduced in balsamic vinegar and coconut oil. Grapes, wine, berries, nuts, bacon, etc. Fats are not the issue. I never count calories but I get on the scale every morning.
If I'm nearly 50, have had 3 kids, and can look like a 22 year old tight body without starving and without killing myself working out all the time, anyone can do it. I weigh 120 lbs and my BMI is 20. It's discipline. Yes I have good genetics...but I know lots of people with better genetics than I who are fat...or worse, belly fat (the highest risk factor for heart disease).
So don't be lazy and accept dad bod. The fit women you most want to impress aren't going to accept dad bod. Nope.
