Get Free Weekly Health Tips from Dr. Hyman

There are several different schools of thought behind obesity and metabolic dysfunction, for example, the energy balance model or “calories-in, calories-out” perspective that many people have felt fooled by. While calories certainly are one piece, there is much more to the puzzle of weight management and metabolic health, like hormonal cascades and oxidative stress.

My guest today is Dr. Robert Lustig, an author and neuroendocrinologist with expertise in metabolism, obesity, and nutrition. He has dedicated his retirement from clinical medicine to help fix the food supply in any way he can, to reduce human suffering, and to promote a collective vision of metabolic health: protect the liver, feed the gut, support the brain.

Mindsip insights from this episode:

Choose foods that protect liver, nourish gut, and support brain

A food is only healthy if it meets three criteria: it protects the liver, feeds the gut, and supports the brain.

Address obesity risk starting before birth

Newborns today weigh almost half a pound more than 25 years ago, and it's all fat, suggesting that factors like the mother's exposure to toxins are causing obesity before a baby's first meal.

Utilize Perfect app for smart grocery shopping tailored to your health

An app called Perfect (perfect.co) can filter your local grocery store's inventory to show you only the items that are metabolically healthy for you.

Limit fructose intake to slow cellular aging

The fructose in sugar generates 100 times more damaging reactive oxygen species (ROS) than glucose, rapidly accelerating the aging process in your cells.

Manage chronic stress to prevent fat storage

Unlike acute stress which burns fat, chronic stress releases Neuropeptide Y (NPY) which signals your fat cells to store fat instead of burning it.

Utilize Monch Monch fiber to sequester sugar and carbohydrates

A new fiber product called Monch Monch uses microcellulose sponges that expand 70-fold in your stomach to sequester sugar and carbohydrates from your meal.

Lower insulin levels to control weight gain

There is no weight gain without the hormone insulin, so the primary goal for weight loss should be to lower your insulin levels.

Address sugar, toxins, and stress to combat obesity

A unifying hypothesis suggests that sugar, environmental toxins, and stress all cause weight gain by generating damaging reactive oxygen species (ROS) in our cells.
