Questions about weight loss

[techno di]

hi i have questions about weight loss and i need some trusted info .

1/ is staying hungry/ preventing self from eating as longer as possible a good idea for weight loss ??
or it is not practical because of the role of leptin hormone in metabolism ?

2/ is the workout more effective after digestion of food / meal i.e ( after 3 to 5 hrs after heavy meal = lunch ) or effective on empty stomach ??
in other words .. does the workout have instantaneous fat burning or instantaneous sugar - in blood - burning ??

3/ what is the role of sleeping in weight loss ?

shall we say the body metabolism is best while sleeping ? if so .. why nutritionists refuse sleeping after meals ? what is the problem in sleeping after meal ??

4/what is the fate of excess protein in body ? i know that excess far and carbs is transformed to fat .

5/ what is the first place that a body burns fat from when it starving for calories ? muscles , abdominal fat or where ?

thank you

1. You don't want to starve yourself, but if you are overweight you will want to eat considerably smaller meals which might make you feel hungry throughout the day as your body adjusts to the new diet.
2. Working out after a large meal can be counter-productive in many cases (there are some cases where it is beneficial). Generally you want to eat small meals throughout the day. A good pre workout meal for mornings would be a banana and a glass of water or small oatmeal and a glass of water.
3. This is a big question. Sleeping plays a huge role in weight loss. Make sure to get enough of it and don't eat before bed for starters. When you go to bed after eating the body goes into a sort of hibernation mode and the food you just ate is more likely to be stored as fat.
4. Excess protein will get stored as fat.

Depends on overall nutritional context. Get your nutritional needs in whatever structure is most manageable for you. That might mean frequent small meals, that might mean fixing up the quality of your meals so that the same amount of satiation provides less energy, that might mean reducing the number of meals per day.

2/ is the workout more effective after digestion of food / meal i.e ( after 3 to 5 hrs after heavy meal = lunch ) or effective on empty stomach ??

My educated answer is "maybe." Does the exact same exercise while fasted burn a higher ratio of fat compared to when not fasted? Honestly, I don't know. Last I checked, the jury was still out on that one (but it has been a while). What's pretty reliable in exercise science, though, is that being fasted limits the amount and intensity of exercise you can safely perform. If you only have a certain period of time in which you can/will exercise each day, then you want to be able to burn the most amount of calories safely in that time window, so my recommendation would be to stick to non-fasted exercise.

If you're still worried about how optimal that is in terms of fat-burning potential, consider this: unused carbs get stored as fat. So if non-fasted exercise does burn more carbs than fat....so what? It means that there will be less energy left over to convert into fat, and if you're in a calorie deficit (which you want to be in for fat loss), then that will mean your body ultimately says: "Hey, look, I have insufficient energy here, better break down some fat so that I don't do that being dead thing that I'm always trying to avoid."

3/ what is the role of sleeping in weight loss ?

Good sleep is probably good for your hormone balance, and good hormone balance is good for metabolic turnover. Mess with your hormones and you mess with your metabolism, so bad sleep might be an issue there.

Good nutritionists won't tell you not to sleep after meals, unless eating before bedtime messes with your ability to get to sleep. A lot of people think that if you eat before your sleep, then because you're less active while sleeping (hopefully) whatever you eat will turn into fat. But it all comes down to over all calorie balance.

4/what is the fate of excess protein in body ? i know that excess far and carbs is transformed to fat .

According to CrazyOldMan, urine; according to me, fat. I'm too lazy to figure out which of us is right (or if we're both wrong), but I figure the body wouldn't excrete an energy source unless converting it into usable energy isn't worth the effort.

5/ what is the first place that a body burns fat from when it starving for calories ? muscles , abdominal fat or where ?

Muscle isn't fat, so not there. Your body might break down muscle tissue to provide energy, though. Strength training can prevent that, and I have one friend who insists that a high fat diet (by % of calories consumed; still being in a calorie deficit) will train the body to use fat for energy thus preventing muscular catabolism, but I wouldn't place my bets on that. Primarily, it'll be body fat getting broken down into usable energy, which is largely a systemic process.

thank you

Actually we are both right and in truth I normally say so.
Protein that is above the level the body can absorb from the gut comes out in faeces. Total waste.
Protein in the body is transported as amino acids, which can break down to ammonia if left floating around too long, they are quite unstable.
Any combinations of amino acids that can be converted to lipoproteins, which is just fat with a fancy name, are because the body doesn't like waste. This is most excess protein and why high protein diets for fat loss are a total joke.
protein lost from damaged tissue and any combinations the body cannot convert to fat have to be removed before becoming toxic so are converted to urea and disposed of with 9 times their volume of water, causing very short term weight loss while gaining fat.

Simple way to tell if an organism is very wasteful of energy, it is either extinct or on the critically endangered list without our influence.


Catabolism is never stopped, but training in a varied manner makes the body less inclined to do so and more inclined to rebuild it consuming energy while at rest.
Pure strength training makes the slow twitch fibres more disposable, comparatively to full spectrum, likewise lack of it while doing stamina and endurance will make fast twitch more disposable comparatively. The best is a full spectrum workout system meaning the body wants to keep all muscle.


Studies regarding time of day you eat compared to sleep that have been well peer reviewed show no benefits that are at a level genetics couldn't easily cover, ergo it is irrelevant based on current knowledge.


Weight loss and gain are best using the KISS system, Keep It Simple Stupid. Eat less in balance while doing more = comparative weight loss or slowed gain, vice versa gives the opposite. Don't go extreme and remember a pound of fat is 2 days of calories for the average person in the modern world so if you lose a pound a day for a week without doing ultra marathons a lot of that was water.
