WHAT IT’S REALLY ABOUT
Fasting, Insulin, Diet Quality and Lifestyle Medicine for Metabolic and Mental Health
- Dr. Pradip Jamnadas describes his stepwise fasting protocol: cut sugar and processed food for two to three weeks, skip meals, then move to 18-hour fasts and eventually one-meal days and a three-day water fast.
- He frames metabolic syndrome and coronary calcium as insulin-driven problems and says weight loss is a side effect of fixing metabolism, noting that patients have come off insulin, blood pressure drugs and statins.
- A second guest, introduced without a name, argues that carbohydrate processing, fructose, food order, vinegar and food monotony matter more than total carbs, and that fasting raises energy and focus rather than burning muscle.
- Another guest covers immunometabolism, postprandial inflammation and omega-3s, arguing that eating too often and eating on the go is a problem and that individual responses to food vary.
- A further guest describes the SMILES trial, in which dietary support produced remission in over 30% of people with depression versus about 8% with social support, and she urges doctors to put diet and lifestyle first.
IDEAS WORTH REMEMBERING
5 ideasEase into fasting gradually rather than starting with long fasts
Jamnadas says he starts with two to three weeks of whole-food eating, then meal skipping, then 18-hour fasts, because going straight to once-a-day eating gave him a higher failure rate. He attributes this to mental and biochemical withdrawal from sugar and addictive foods.
Weight is a side effect of metabolic dysfunction
Jamnadas argues that insulin-driven fat in the liver, pancreas and visceral gut is inflammatory, so his fasting program is a metabolic program in which weight loss follows from fixing the metabolism.
Coronary calcium scoring can reveal disease that standard tests miss
Jamnadas says a CT calcium score shows atherosclerosis directly in people who pass stress tests and have normal cholesterol, and he uses it to motivate patients. He also uses it to stop statins in some patients whose score is zero.
How you eat carbohydrates matters as much as how much
A guest says unprocessed carbs, acid such as vinegar or lemon, and eating carbs after protein and fat all lower insulin responses to the same amount of carbohydrate. He suggests fructose and a monotonous diet help explain why 1980s China ate lots of white rice without obesity.
Fasting does not simply burn muscle and can raise energy
The guest says exercise, not eating, determines muscle, and fasting breaks down unneeded protein such as skin and connective tissue through autophagy. He adds that rising adrenaline and growth hormone during fasting can improve energy and concentration.

I really do think societally, culturally, there's a problem with how much we're being encouraged to eat, even healthy foods.

Type 2 diabetes is largely a dietary disease, and we're using drugs to control a dietary disease, but you're not going to get as much effect as you think you will because you're not focused on the root cause, which is the diet.

it's sorta like storing firewood, you know, for the winter, and then as soon as it gets a little cold, you chop up your sofa and throw it in the fire.
