How do you know when it's time to go 40/30/30?

You can't expect to lose 2lbs per week forever, especially as you get leaner.

This doesn't mean you have to chnge your macros, I take It that you are still losing?

Whats your bf%, how big is your deficit and What are your macros currently?

Bump

Why are you eating that low as a man? That's generally too low for a lot of women, let alone a man who will always have higher nutritional needs.

Secondly what is your height? 135lb seems quite light...

I've always done 40/30/30. I run and I lift. It just feels better for me. Personal preference, though.

The difference between 45/30/25 and 40/30/30 is pretty damn minor and likely won't make a difference. But eating at 1200 is pretty absurd for an adult male.

Sufficient protein is required. Around 0.5g per lb of lean body mass minimal. I sit somewhere in the middle of that 1.5g P/LBM max. After that and the fat that comes with the protein, there isn't a whole lot of room for carbs.

1200 calorie restriction

first mistake...

I don't plan on building muscle just yet?

second mistake

Macros really have nothing to do with it, it's about calories. Changing your macros won't change your weight loss, if the calorie deficit is the same.

Nope.

Calories is not everything.

Try a diet that is 100% carbs with no source of protein and fat. Hormones will be a terrible mess. You will start wasting away slowly from the lack of protein. A whole slew of potential health problems can arise.

Protein is a must. Fat is a must. Carbs are not required at all. So get enough protein and fat, fill the rest in with carbs based on your goals. I think that is optimal.

Edit: If you want to lose fat quickly, you should consider intermittent fasting. That away you can eat more to keep yourself satisfied and healthy while creating a deficit. Prolonged VLCD does have side effects and will cause stalling.

ok Mr Extremist...never did anyone say NO protein or fats...

simply that going from, say, 55/30/15 to 40/30/30, for example, won't affect the way your body burns calories and loses weight if the calorie deficit remains constant...

sure, some people get a flatter belly from going lower carb, for instance, but that is because of bloat, AKA WATER weight, not FAT.
Less carbs, means less glycogen storage, means lower number on the scale...but it does NOT mean less BODY FAT.

Carbs may not be required for SURVIVAL, but you brought up hormones. Carbs are rather necessary in order for the body to properly regulate anabolic hormones.

That is true. However, this person is on a cut. Also, Protein does trigger insulin. There are natural body builders that build muscle on a carb restricted diet. Protein is the primary modifier. My suggestion to get enough protein basically requires a cut in carbs. Going Keto isn't what I'm suggesting or is it necessary. Keto while cutting is very effective though.

This is a bad example, but Arnold was very low carb when he was training. Even though he had massive amounts of steriods, carbs were very minimal. That only serves as an example but does not make the rule. Glycogen does greatly help in the muscle building process.

Hormones are very important even on a cut. They help to control appetite and mood. Getting enough fat greatly helps that.

I'm not being extreme. I'm just giving advice. It was said that only calories matter and macros don't. I said otherwise. Big deal.

The second thing you said could be correct about the minor change in macros. We don't really know. I'm just suggesting more protein and fat to help. That's all I'm doing.

I didn't say anything about the scale. I'm giving advice for cutting fat. Yes, water weight is reduced when reducing carbs, but fat loss still happens. My main point is to maintain LBM and have stable hormones while cutting.

I don't think it's ever time to go 40/30/30, because that ratio is about as accurate and useful as the food period. There is absolutely no reason whatsoever to eat more carbs than protein.

You should eat your .8-1g protein per pound of body weight a day, and shoot for 25% of your calories to come from fat. Leave the rest for carbs, which works out to be ~20% for me.

Personally I shoot for 1g protein per LBM so at least 120g protein per day.
Fat fluctuates from .30-.75g per LBM depending on if I lift or I'm resting.
Carbs make up the rest.

When I started it was protein and Fat 30% each.
