That’s right. The next meal is breakfast tomorrow. You can do this without starving. You consumed 500 calories today. Yesterday and tomorrow with be the normal number of calories you eat.

Hi, W4Foodie! I also just had my first fast day yesterday, everything went ok, I even went to the gym for an hour but this morning, even if I had a very nice breakfast (porridge, banana, coffee with milk and a full glass of orange juice) I felt dizzy in the morning, and my vision was a little blurry. After my lunch, everything went back to normal. But I was really concerned this morning, because nobody else talked about dizziness on a feast day! Hope this was the only incident. Have a nice evening

hi gi foods/low gl foods refer to foods with a glyceamic indesx count which is high. the gycaemic index determines how well your whole meatbolic process manages the digestion of the food. so (e.g) sugary foods have a very high gycaemic index/low glyceamic load- they pass through the body very quickly and your insulin level rockets
whilst (e.g.)veg has a very high glycaemic load/low glaecymic index and gives the metabolic system and your cells retained energy that wont be laid down as fat due to high insulin and it will go through your body very slowly and gently rather than straight through, so alot more vitamins and minerals can be absorbed.

i learnt about it from weightwatchers first and then recently from books by dr Patrick holford.

Hello davidrob –
I am very confused by your explanations of glycaenic index and glycaemic load. I have done the Patrick Holford diet quite successfully a few years ago.

As you say it is all to do with how much a food will raise insulin level compared with how much table sugar will raise it. This gives the GI. Surprisingly even wholemeal bread will raise the level higher than an equivalent weight of sugar, so if you do the diet you will find yourself substituting oat cakes and pumpernickel for ordinary breads. And some fruits like bananas and grapes ate much higher than others,like berries and pears. And most vegetables are lower than fruits.

Where GL comes in is taking GI and looking at portion sizes. Carrots are quite high GI but you are not likely to eat even a whole one in a meal, so that makes them more acceptable than say potatoes.

It is a fascinating subject and well worth looking into if you suspect carbohydrates are contributing to your weight issues but don’t want to go onto a low carb regime
