First off lets us a define what is a low fat diet. A very low fat diet is where anything under 10 percent of the total calories consumed comes from fat. So that's 26 grams per day or less. On a fat loss diet of 1500 calories, 10% is only 15 grams of fat per day.
The problem with trying to lose weight is that most people do not maintain a balance. They stop everything and exercise furiously. Once you're over thirty this does not work. This is because when you cut the food intake by over 15% your mind gets a hint that you are not getting enough to eat.
When your blood sugar spikes, your pancreas releases a lot of insulin to bring blood sugar back down to normal. Now moderate amounts of insulin are necessary (and anabolic). However considerable amounts of insulin are what's called lipogenic (cause fat storage) and anti-lipolyic (stop fat release). If trying to lose weight this isn't the state you want your body.

I begin my trip by checking my diet and my eating habits. I was appalled. This was nothing like the health nut I was. Chips, pizzas, a lot of fast food, 3 to 4 soft drinks each day, snacking on chocolate snacks through the day, and maintaining snacks at my desk all changed my 4 pack(never got the 6) into a spare tire with off road treads. The first thing I did was eliminate all sweets from my house and my office, to eliminate temptation during this.
The moral of this story is this - if you find out are a guy and you feel'spaced out' all get your T level checked. If it ends up that it is associated with T that is low you have options open to you - it's a condition that can be managed to improve your quality of life.
