No Carbs no Sugar?

Hi Jim,

I am currently following a fat loss program that has a requirement to not to take any sugar. At least not in the first 2 week detox period where you are only supposed to eat protein and vegetables, even no fruit allowed. Is this ok not to eat, enough carbs and Sugar? i.e. no fruit, no dairy food (yoghurt, milk), no grains, no bread, no oat meal, no bran flakes or even no rice. Is it healthy to stick protein only diet?

My second question is not related to this plan, but rather it’s a general question.
I have no knowledge of Insulin, the regulation of Glucose and roll of Glycogen but I have been told by someone not to take any pre workout or any support drink during workout with sugar or carbs if fat loss is my goal, just because when you exercise your body needs energy and if there are not enough carbs and sugar it will need to make it by breaking down and burning fat as a source of energy. This information may be partially incorrect because I did not understand it fully to be honest.

My question is should I really stop taking any pre-workout supplement? and during workout?

I want to energise myself during workout but every supplement I saw has carbs and most have sugar in it.
I have been use to drink following supplements to boost my workout and recover after.
1) pre-workout :“01 GATORADE G Series Pro Prime Gel” (24 g Carbohydrates, 22 G Sugars per serving)
2) During: “02 GATORADE G Series Pro Perform OR Lucozade Sport Body Fuel” (30 g Carbohydrates, 30 g Sugars per serving)
3) Post workout: “03 GATORADE G Series Pro Recover” after workout (14 g Carbohydrates, Sugars 13 per serving)
Should I stop taking them if fat loss is my goal?

I am cheating a little bit and taking a sugar free pre workout supplement Optimum Nutrition Amino Energy (only 2 g Carbohydrates and is sugar free). It contains most of the energy boosters you mentioned in your HIIT training e book. i.e. (NO Booster (Nitric Oxide), Beta-alanine, BCAAs, Caffeine, Green Tea Extract) I am taking Creatine separately as well. And to cover up “Carnitine” I bought Optimum Nutrition L Carnitine Tabs but it’s not mentioned on the bottle to take it as preworkout. It just says “Take 1 tablet daily on an empty stomach”. Is “L Carnitine” is diferent then “Carnitine”?
Also I have been told I can drink “Chlorophyll” during workout to enhance energy and also speeding up the fat loss. Is it a good supplement?

I am sorry to making it lengthy. Not sure should I ask all of these questions separately on in one go.
