I'm doing IF on my cut so far 217 > 200 after almost 8 weeks. I like it for sure! Was a lil skeptical at first and was hungry first couple of weeks but my body adjusted and feeling great! Working out after the 16 hr fast feels great and I have a good amount of energy.
It see ms like more folks are getting great results with IF.
Things do slow down as you get to 40 from what 20 was like but the training style is pretty much the same for me. As far as dieting I find that eating two large meals a day works for me while having a protein shake for breakfast.
I am almost 53 years old. I started lifting weights again after many years. I gained about 7 pounds of muscle and 7 pounds of fat during my bulking period the last 6 months. To my surprise I noticed it didn't make a big difference between lifting heavy or light, diet had a much greater impact on my progress and muscle mass.
