A 2014 Harvard study found that men who did twenty minutes of daily weight training had less of an increase in age-related abdominal fat compared with men who spent the same amount of time doing aerobic activities, and other studies have shown similar levels of success when guys hit the gym to cut down on fat. The implication: Guys can cut belly fat most efficiently with weight training.
The study began with 609 relatively healthy overweight and obese people, and 481 completed the whole year. For the first month, everyone did what they usually did. Then, for the next eight weeks, the low-fat group reduced their total fat intake to 20 grams per day, and the low-carb group reduced their total carbohydrate intake to 20 grams per day. These are incredibly restricted amounts, considering that there are 26 grams of carbs in the yogurt drink I’m enjoying as I write this, and 21 grams of fat in my half of the dark chocolate bar my husband and I split for dessert last night.
Sure, you can lose weight quickly. There are plenty of fad diets that work to shed pounds rapidly -- while leaving you feeling hungry and deprived. But what good is losing weight only to regain it? To keep pounds off permanently, it's best to lose weight slowly. And many experts say you can do that without going on a "diet." Instead, the key is making simple tweaks to your lifestyle.
