What some of the guys are saying is go to your doctor and get your testosterone level checked. Normal range for a male is usually between 400-900 if your below that then your doctor should prescribe either a cream, or even better weekly test injections. You really want your testosterone level at around the 900 range. This does a man a lot of good. 1. Will help you to keep both muscle and bone mass. 2. Sex drive and great hard-ons, enough said. 3. Low testosterone is as bad for you as too high of test. Low test can cause prostate issues, depression, lethargy, and many other health problems. We have the resources to keep our test levels at the same levels we had when we were in our 20's, why not use it. If your doctor won't help you with this, get a new doctor. Women have all kinds of hormone therapies evadable to them, why shouldn't men. I'm 46 and in the best shape of my life. I keep my test levels on the high side and feel great. I work out 4 or 5 days a week, 1/2 hour weights and 1/2 hour cardio on a stationary bike. I'm not some insane gym whore, I am in and out. I'm 5'10 195lbs and solid as a rock. Go to your doctor, get your test checked, I bet your numbers are low. Join gym and start slow and sensible. Get on a good 1600 to 1800 calorie a day diet of good healthy whole foods, that means don't shop in the center isle of the store, shop around the edges. Good lean meats, chicken, fish, steak, quality fresh vegetables, not canned, or frozen, keep fruits to a minimum lots of sugar there that will spike insulin levels and make you retain fat. Eat three meals a day, breakfast, lunch, and dinner, with two snacks in between. Main meals should be 400 calories apiece, and snack should be 200 calories each. No carbs at all at night, strictly meats and veggies. Consume most of your carbs at breakfast and lunch. My snacks are usually two boiled eggs, and a little cup of almonds and craisins, or 1/2 an apple and a little cup of all natural peanut butter to dip the apple in. Their are protein bars that you eat for snack, make sure they are 200 calories or less.
