I recently had the opportunity to read Tim Ferriss's The Four Hour Body. His book is worth a look - quite an interesting viewpoint. The diet he promotes is low carb, but he encourages beans or lentils - a lot of them.
What interested me, though, was the excuses I read:
"This is obviously written for a bachelor/young man who eats out twice a day."
"I can't follow this because I'm a woman and this was written for a man."
"I can't do this because I'm a mother with young children at home and I'd have to prepare two meals."
See the pattern?
Honestly, darn near any weight loss program you choose to follow will work over time. Watch your calories, up your protein (ladies especially), eat lots of vegetables, easy on the fruit, no processed foods.
If you want something, you will find a way. If not, you will find an excuse.
