How to lose body-fat healthily.

Previous blog posts have been about Carbohydrates, Fats & Proteins. However, when you go shopping, you buy food. So this blog post is going to be about food. Updated!

1) If you're eating a high-carb diet, eat 6 small meals or 3 meals and 3 snacks per day to keep your blood glucose relatively stable. I used to believe that it also kept your metabolic rate high, but I now know this to be a myth. If you're the type of person who gets lowish blood glucose in the mornings (which may make you ravenously hungry and therefore highly likely to buy junk food when you're away from home), skipping breakfast is not advisable. If you're the type of person who isn't satisfied by small meals/snacks, a small number of large meals (Intermittent Fasting) is a better option.

2) Meals and snacks should contain proteins, fats and fibrous carbs.

3) Slow sugary/starchy carbs can be eaten in meals/snacks at breakfast and before/after workouts/exercise/intense activity. If/when you are sedentary, keep slow sugary/starchy carbs to a minimum. Keep fast sugary/starchy carbs to a minimum (except for the occasional treat or post-workout) as they can cause large fluctuations in blood glucose and insulin levels. The more intense exercise you do, the more slow sugary/starchy carbs you can eat.

4) Drink >1.5 litres of no-added-sugar watery drinks per day. If your urine is darker than straw, drink more. If you're weeing too often, drink less.

5) Balance your omega-6 and omega-3 essential fatty acids (EFAs) by eating about 100g of omega-3 rich oily fish (sild, sardines, pilchards, mackerel, herring, salmon, trout, fresh tuna etc) per day
or supplement with fish oil capsules such that you get at least 2g of EPA+DHA per day. Please note that tinned tuna contains virtually zero omega-3 fat.

If you're vegetarian or vegan, see
Vegetarians & vegans, listen up!

6) Eat 2 to 3 portions of low-sugar fruits per day - preferably before meals/snacks. Minimise your consumption of high-sugar fruits.

Proteins are:- Meats, poultry, fish, eggs, cheese, Quorn, seeds, nuts, legumes (peas, beans & lentils).

Fibrous carbs are:- All vegetables that grow above ground level, bulbs (onions, leeks, garlic etc) and "vegetable" fruits (tomatoes, peppers,
cucumbers/courgettes, aubergines, avocados, olives etc).
Slow sugary/starchy carbs are:- All-bran, no-added-sugar muesli, oats, sweet potatoes, lightly-boiled new potatoes eaten hot, cold or refrigerated, Basmati rice, non-overcooked legumes & root veggies, lumpy wholegrain rye breads, Burgen/Vogel's soya & linseed breads.

Fast sugary/starchy carbs are:- White wheat breads, wholemeal wheat breads, most breakfast cereals including Shredded Wheat, Weetabix, Cheerios, Grapenuts etc, sugar, sweets, chocolate, cakes, biscuits, cereal bars, sweetcorn, overcooked tubers e.g. jacket potatoes, overcooked root veggies, overcooked legumes e.g. baked beans.

High sugar fruits are:- Ripe & over-ripe bananas, grapes, pineapples, sweet apples, sweet pears, sultanas, raisins, currants and any dried fruits with added sugar.

Low sugar fruits are:- Berries, stone fruits, citrus, Granny Smith apples, Conference pears. Dried apple rings, apricots, pear halves, peach halves and prunes without added sugar are high in sugar but they release that sugar very slowly.

Fats are sats, monos and the EFAs mentioned above. Butter is high in sats and monos. Olive oil & spreads are high in monos. Sunflower/safflower/corn oils & spreads are very high in omega-6 EFAs - minimise your consumption of these. Don't fry or roast with high-EFA oils as they oxidise and convert into trans-fats too quickly. Meats contain sats, monos and some EFAs. Minimise your consumption of anything with the word "hydrogenated" in the ingredients list.

Some foods fall in-between categories like yellow bananas which are medium speed sugary/starchy carbs. Green bananas are slow carbs and black bananas are fast carbs.

Depending on your insulin sensitivity, speed of metabolism and exercise levels, you may get away with eating fast sugary/starchy carbs - you'll just have to "suck it and see".

If eating makes you feel drowsy followed by hunger, you probably have Insulin Resistance. See Insulin Resistance: Solutions to problems. for ways to reverse Insulin Resistance.

One final bijou tip-ette:- Avoid walking down "dodgy" supermarket aisles (confectionery, cereals, booze, fizzy drinks) as "What the eye don't see, the heart don't grieve over".

Happy New Year folks!

Per "We are All Different", hypoglycemia does NOT make me hungry, just weak and dizzy. And yes, I have a glycometer. I have to force myself to eat under low glucose conditions. If I followed your 6 feedings a day prescription, I'd weigh 300 pounds!

Nigel Kinbrum said...

Meh! There's always one. ;-p

If the 6 feedings are big, then yes you'll get fat.

If the 6 feedings contain the same number of calories as 3 double-size feedings, there is no difference.

Do you not like small meals/snacks?

ProudDaddy said...

What do you call it, "ad libitum"? Point is, my hunger/homeostasis mechanism is unrelated to glucose level and nearly the same for every feeding, whether a snack or full meal. I simple eat fewer calories (total) if I eat less often. Then I believe there are studies that indicate once insulin gets past the blood-brain barrier, it becomes a hunger suppressant.

P.S. As you may have guessed, I'm working my way through all your posts, so I'll be a bit of a pest for a while. Please feel free to ignore any comments that you don't find interesting.

Nigel Kinbrum said...

So Intermittent Fasting (or Intermittent Eating as I think of it) suits you.

ProudDaddy said...

Yep, it does, along with a low-moderate carb, moderate-high protein, and moderate fat diet.

Nigel Kinbrum said...

It's good that you are reading & critiquing my posts as some of them need updating. I've updated this one and the one about Carbohydrates.

I think everything published was actually very logical.
But, what about this? what if you were to create a awesome title?

I am not suggesting your content isn't good, but suppose you added a post title that grabbed a person's
attention? I mean "How to lose body-fat healthily." is a little
plain. You should peek at Yahoo's home page and watch how they create article headlines to get people to open the links. You might add a related video or a related pic or two to grab readers interested about everything've got to say.

Just my opinion, it might make your posts a little bit more interesting.
