2. Your metabolism just isn't what it used to be.
When you were younger, you could easily down a few jelly donuts without any consequences. Fast forward to your older self and you swear you could gain a pound just looking at a donut hole. According to Dr. Oz, your metabolism slows down 5 percent, every decade after you turn 40. Your metabolism is your body converting food into energy. When this slows down, you can't burn calories like you used to. Many experts say that to counter this, you just need to trim off about 100 calories a day from your diet. It may not seem like a lot, but the calories can quickly add up. At 100 extra calories a day, 365 days a year, you're looking at up to 10 pounds of weight you can possibly gain.

If you want to lose 20 pounds of fat, build major muscle, and boost your testosterone, pair your workouts with these food rules from sports nutritionist Tara Gidus, ., team dietitian for the NBA's Orlando Magic.
