A new analysis projects annual health care cost reaching $6 TRILLION in 2027, as baby boomers age. That's about $17,000 per person and 20% of GDP. But this massive economic burden could be reduced with better diet and more successful obesity treatment

Metabolic rate decreases after bariatric surgery by more than expected from weight (fat) loss alone, as seen in a new observational study in adolescents. Can this decrease (which predisposes to weight regain) be reversed by diet or other measures?

What's in the $86 billion a year Farm Bill (approximately $500 per US adult)? and colleagues unpack this juggernaut in a JAMA Viewpoint, and recommend ways to better align policy with public health

Fair point. Though a persistent criticism is that this change is therefore observational, with no formal control (thus, possibly confounded by any time-varying covariate). One would need a third group, with either a low GI source of glucose or lower total carbohydrate to know.

In this case, I agree with Guyenet. The Stanhope study examines fructose, which at high levels can cause metabolic problems independent of insulin. To test CIM, we need to look at slow vs fast digesting carbohydrate; or high vs low carbohydrates.

Probably don't have the bandwidth in the next few months (l seem to have committed to travel every other week through June!). Happy to Skype with you to make professional acquaintance . . . and maybe set the stage for a Podcast at some later date.

Many points worthy of debate. On one, here's the most complete analysis of dietary fat, supporting a peak of ≈42% around 1960. Keep in mind AHA strongly advised fat reduction (and endorsed those sugary cereals) well before official USDA recommendations:

Let’s restore this critical academic tradition (often forgotten in the field of nutrition): CRITICIZE THE ARGUMENT, NOT THE PERSON. Ad hominem attack is always a distraction.

In type 1 diabetes, higher insulin dose is associated with CVD. Two possible directions of effect: FORWARD: high insulin dose (eg, related to diet) causes disease REVERSE: unhealthy people need more insulin 👉Trials of low vs high carb diets in T1D needed

Many have argued virtually all advertisements for processed foods aimed at children are harmful. And perhaps all food ads period, as adult eating habits are adversely affect too (if not, why would food companies spend all the $$$?)

Beer, BudLite & Super Bowl: I don't typically see eye to eye with , but when it comes to nutrition, the glucose source for beer fermentation – corn syrup vs other enzymatically treated grain – shouldn't much matter. (Taste we can all debate)

Mice with genetically reduced insulin secretion (no change in glucose) may have protection against pancreatic cancer. 👉Authors' conclusion: "reduction in fasting insulin via lifestyle interventions or therapeutics may be useful in cancer prevention"

In a US study, incidence of obesity-related cancer (myeloma, colorectal, uterine, gallbladder, kidney, pancreatic) increased through successive generations, especially among younger adults. Most non-obesity related cancers did not show this pattern.

Agree. Also of relevance, biological adaptation resist acute weight gain (not just weight loss), as the classic over feeding studies show. (Admittedly, the long-term weight slope for most people is gradually positive)
