Maximum Fat Loss Dietary Macros (per day)
This diet is a variant on the Protein Sparing Modified Fast (PSMF) diet.
With this diet it is very important that you eat at least the protein amount.
This preserves the most lean body mass possible and provides satiety.
It is also important to eat at least the total number of calories.
If you go below these numbers you risk lowering your metabolism and you actually can't lose body fat any faster.
It is better to be slightly above these macros than below the macros.
It is also OK to substitute additional protein for fat (as long as total calories are reached) but you may feel better with as much fat as possible.
Don't forget that Protein plus Insulin builds muscle.
Maximum Fat Loss Notes
Can You Do an Extended Fast?
One important question to ask when considering extended fasting is whether or not you have sufficient body fat to fast.
How Much Muscle Can You Gain?
I do not recommend the Zone diet although it works well for some people.
The Zone diet is presented here for comparison/contrast to keto.
The reason that the Zone diet works is that it doubles the protein of the Standard American Diet (SAD) and reduces the carbs from 50% to 40% of calories.
Standard American Diet (SAD) Macros
I 100% do not recommend the Standard American diet.
It is presented here for comparison/contrast to healthier eating choices.
- There are three food macros; Protein, Fat and Carbohydrates.
- Every diet manipulates two variables - total number of calories and percent of calories by macro.
- Here is a comparison of various diets by macros:
- Weight loss interacts with hormones.
- Not all diets produce the same hormonal response in humans.
- Insulin is a hormone and is created in the body in different amounts based on the macronutrient.
- High carbohydrate diets produce a greater insulin response. This is how the body lowers the blood sugar from eating carbohydrates.
- As a macro, fat has very little blood sugar and Insulin response.
- Eating protein is necessary to keep the body from eating up it's own muscle and protein.
