How blood sugar impacts your mood, hunger and energy | Prof. Sarah Berry and Prof. Tim Spector

What does the latest science say about how blood glucose spikes impact our hunger, energy and mood?

Jonathan talks with two King’s College London professors to try and find out.

Prof Sarah Berry is a professor in the department of nutritional sciences at King's College London and chief scientist at ZOE. Prof. Tim Spector is one of the world's top 100 most cited scientists and scientific co-founder of ZOE.

Home-made porridge using organic jumbo oats and full-fat milk will make me helplessly sleepy a couple of hours later, so fibre and “whole grains” don’t work for everyone. Same with baked potato even with tuna mayo or cheese. But cutting them (and rice, pasta, bread etc) more or less out was a colossal improvement.

I have read many books, I listened to many Youtube videos by many of the world's leading gurus and health experts but nothing came close to the 23 former doctor truths by lauren clark. I recommend everyone giving it a read.

Intact whole grains are very slow carbs that also feed your good gut bacteria. Brown rice, wheat berries, oat groats, barley, rye, buckwheat, amaranth, sorghum, teff, millet etcetera

Glad Tim added that about smoothies. I put plenty of red cabbage and collards in my smoothies. Also some almonds and seeds. Just enough banana or berries to make it taste fine. And some oats. It fills me up for ages. Best meal I have personally found for long last energy and it's pretty low calorie. While I may lose some polyphenols from the banana (or grapes I sometimes add) - I get sulforaphane in high amounts from red cabbage as smashing it up helps make even more!

Can you make an episode on autoimmune conditions please?

When is Zoe test going to be available in Australia?

I really appreciate this content, but usually dont watch because it's too long. Thanks for a shorter clip this time.

I lost a lot of weight using vegetable smoothies. Minimal fruit. Mainly ginger to help the hunger pangs. After 6 weeks I'd lost a load and moved on to more normal diet

Hello, I love and follow your content religiously! Never commented before so I don't know if this will be seen or replied to but here goes! I can't recall seeing anything in your videos about "resistant starch"? Is it a "thing"? If it's been discussed please direct me to the content, thanks! Sean

My spikes are about an hour later on cgm but can be modified with protein/fat salad vinegar and veggies first then exercise etc ... I can't manage lentils/ beans / pasta without a big spike and have a smaller amount of wholegrains (all not even rye or sourdough) /potatoes than I used to ... Fasting insulin is good as is HBA1 so it's just glucose sensitivity ... But I used to feel ill with these spikes and as at 1hr + never related to a meal until wore cgm

I am interested in a discussion on ground and freeze-dried fruits and veggies. How is that different than the problems with drinking apple juice?

[michaelross]

A lot of common sense here and also emphasising the fact that we are all different and can react differently to the same foods.

[claymor]

Practically the only food I’ve eaten with significant sugar content over last six years or so has been raw fruit. I’ve gone to great lengths to control carbs generally as a part of my diet. However, as exception to that rule I ate auite a lot of fruit throughout the day - five a day and often more. No fruit juices, just raw fruit and some raisins. A month ago I was diagnosed, after a blood test, as prediabetic. Too much fruit turned out to be bad for me, despite all the advice out there.

[juleskayak]

So would you say that porridge for breakfast is just as bad as cereal or toast wrt carbs?

[mattsonics]

I think there is a generalisation about the kind of work people undertake. I eat porridge for breakfast at 0830!. and then graft, dont have a dip until I feel hungry for lunch at 1. If i was sitting at a desk i suspect it would be a very different story. Suspect sugars are being used!?

[spurgendahl]

Interesting with that dip... Once, two hours after an OGTT, oral glucose tolerance test, I surprisingly suffered from a slight hypo, with a blood glucose level of 68. A standardized amount of glucose is by no means a meal, but maybe the test was misinterpreted due to that dip.

[nikkysings]

My tummy is kind of funny it gets so stuffed with carbs and it digests very slowly as well. But reducing and cutting down on carbs and exercising more it helps a lot. Xx

[lynnoorman]

Thank you for a shorter clip, with actionable advice. The 'trust your body' message imo, is a bit dangerous, as many people have been programmed by various life events to have very scrambled messages from their body. Needs mentioning.

[swsblyth]

I am not sensitive to whole grain carbs but cannot eat fat.
