no you're wrong. he's right.
Think about this:
dave walks an hour to work between 7am and 8am, sits at his desk for 8 hours then walks home at 5pm till 6pm. He sits down until 10pm and then goes to sleep.
during his day he burns 2000 calories.
It's irrelevant whether he takes in those 2000 calories all in one go, all at 10pm, all at 7am or gradually throughout the day. he still takes in the same calories and he still uses up the same number.
That is TOTALLY wrong - consume 2000 calories at one sitting and your body cannot properly process it all and a larger proportion will be turned into fat than if you had consumed it over 5 - 6 smaller meals.
Consume it at 7am and he will use a lot of it over the day including at least some of the extra fat - consume it at night and he will not.
The trouble with most diets is that your body craves fat because it is the most energy dense medium there is - 1gm fat contains 9 calories while 1 gm protein or carbs each contain 4 calories.
And, unfortunately, because body fat and the fat we eat are chemically fairly similar it is very easy for your body to convert that fat into body fat - this is a mechanism developed over thousands of years of evolution to help our ancestors through the times when food was scarce - it is only in the last 60 years or so that food has been plentiful and our bodies simply cannot cope with that change - we still store fat waiting for famines to turn up because it is the most efficient way to store energy.
Unfortunately our bodies cannot utilise these fat reserves until we have depleted our other energy reserves - notably glucose and glycogen both os which are forms of sugar.
Your body uses glucose as energy but cannot store it but it stores glycogen in both the liver and muscles.
When energy is needed the liver converts glycogen into glucose which is then used as energy - the glycogen in muscles can only be used by the muscles and is not converted back to glucose.
The controller of this is insulin (produced by the pancreas) which when working properly maintains an even glucose level.
If your glucose ( and thus energy) levels fall the pancreas produces glucogen which stimulates the liver so that it converts some glycogen into glucose for the energy needed and if your blood glucose is too high the reverse takes place and some of the glucose is converted into glycogen.
However your liver can only store about 100 gms of glycogen which is about 3-4 hours of normal activity and once that store is full THEN if your blood is still getting glucose coming in from a heavy meal your liver then converts it into FAT
Thus eating a very large meal, especially at nights when exercise is minimal, a large proportion of that 2000 calories will be converted into FAT- and that is a scientific fact.
Eat 5 smaller meals during the day (starting with breakfast) and your glucose levels will remain fairly constant so minimal fat will be produced for your body to store.
But our bodies crave fat so that is why low fat diets usually fail - if you want to lose body fat the best way is with 5 small meals containing approx 15% fat along with approx 45% protein and 40% carbs.
You also need to go into a calorie deficit, meaning that you eat less than you consume as energy - remember that 3500 calories is the equivalent of 1lb in body weight which means that to lose 1 lb/week you need to consume 3500 calories less each week - or 500 calories less each day.
Add extra exercise on top of that and you can lose more than that but once per week you need to come off the diet and have a mild "binge" day otherwise your body will go into "starvation" mode and will start to conserve its stores of fat by reducing its energy levels - and you will start to feel lethargic and lacking energy.
This is only a very small posting on a very large subject but I hope it will lay to rest some of the rubbish which many people seem all too willing to believe on this subject.
