EB. 138: How Low-Carb Diets Worsen AGE Formation (and What to Do Instead)

In this episode we discuss:

• How glucose and insulin decrease glycation

• Why ketogenic diets can be worse than high-carb diets when it comes to AGE formation

• How autophagy helps to clear AGEs, but increasing autophagy is not the answer

• The true primary drivers of AGE accumulation

• The best diet and supplements for minimizing glycation

Timestamps:

0:00 – intro

0:57 – how glycation products are detoxified and cleared from the body

4:03 – glycation detoxification is impaired by oxidative stress and inflammation, as seen in type 2 diabetes

7:56 – the benefits of carbohydrates for the detoxification of glycation products

10:42 – the benefits of insulin for the detoxification of glycation products

12:45 – how AGEs are cleared

14:36 – increasing autophagy via hormesis is not the answer for clearing AGEs

19:09 – autophagy can drive disease

20:50 – ATP protects against oxidative stress and allows for proper autophagy when needed

24:37 – impaired mitochondrial along with fatty acid oxidation impairs autophagy and increases oxidative stress

26:54 – carbohydrates do NOT inhibit autophagy

29:18 – adequate thyroid hormone supports proper autophagy

30:15 – adequate ATP and mitochondrial function is needed for the UPS (ubiquitin proteasome system)

32:56 – do high-carb diets actually impair metabolism and insulin sensitivity

35:26 – is fructose really worse for blood sugar regulation and glycation?

37:16 – are low-carb or ketogenic diets the solution to reduce glycation?

40:32 – increased glycation and oxidative stress on ketogenic diets

44:09 –low-carb diets don’t prevent glucose exposure

47:56 – there are still considerable insulin and glucose excursions on low-carb diets

50:06 – gluconeogenesis leads to same glycolytic intermediates as glucose metabolism

51:52 –the main driver of AGE formation and impaired AGE clearance

53:40 – the role of vitamin B1 (thiamine) and mitochondrial energy production in decreasing AGEs

56:27 –endotoxin as a driver of glycation and increased AGE production

58:12 – hypothyroidism as a driver of glycation and AGE accumulation

59:37 – dietary solutions for reducing glycation and AGEs

1:03:33 – how to support the glyoxalase pathway to support the detoxification of glycation products

1:05:56 – avoid calorie restriction, low-carb diets, fasting, resveratrol, cold exposure, excess exercise, and iron overload to decrease glycation and AGEs

1:07:33 – iron as a double-edged sword for oxidative stress
