But with diet and exercise, throughout a lifespan, you want to not exclude things that are helping you.

For example, during puberty, if you're consuming dairy and then all of a sudden you cut out all dairy, dairy can help increase IGF-1 and free IGF-1.

It helps you grow.

It helps with genital development, secondary sexual characteristics, and long bone growth, skin growth, hair growth, a host of things.

You want to have adequate vitamin D. Vitamin D helps with testosterone production.

It helps, again, with bone mineralization and stature.

After an age of about 25, and there's not a strict cutoff, but up to about an age of 25, optimizing your growth hormone and IGF-1 helps with bone density and bone growth.

So from the dietary standpoint, you want to have enough free estrogen, not too much when you're growing, but you want to help basically stockpile bone to prevent a risk of osteoporosis or thin bones fractures when you're older.

In their late 20s, it might be a reasonable option.

In early 20s and certainly teens, it is a horrible idea because it is likely to significantly decrease your free androgens.

So you will have less testosterone acting on receptors through the body.

Fiber is going to be paramount in kind of like setting your set point of your gut microbiome the rest of your life.

There is prebiotic fiber, which you could think of as fish food for your good gut microbiome.

Your gut microbiome is kind of like an aquarium or a fish tank.

Any fiber or food that you're putting in your gut

it's going to skew your gut microbiome towards something that is more beneficial or more detrimental.

throughout the lifespan particularly important in the teenage 20s 30s because it helps with brain development you're certainly more of an expert than me when it comes to brain development but it does continue to develop really throughout the lifespan but certainly through the 20s and 30s as well in a previous discussion of ours i asked you about

That's correct.

If you look at an individual in a caloric deficit, several changes will happen.

One is that they'll have less building blocks for hormones.
