Not sure this is the right place for this query , but what affects will all the full fat , butter and coconut oil have on cholesterol levels ?

Shouldn’t have much effect if you reduce your carb intake as Dr MM suggests in the book. Here’s a research paper on alternate day fasting comparing a high fat and low fat diet. Sadly it’s only the abstract as the paper isn’t free. Krista Varady is one of the authors and she refers to this article in her book, confirming that LDL cholesterol went down in both high fat and low fat groups in the study. So did blood pressure.

“Alternate day fasting (ADF) with a high-fat diet produces similar weight loss and cardio-protection as ADF with a low-fat diet. M C Klempel et al

“Alternate day fasting (ADF) with a low-fat (LF) diet is effective for weight loss and cardio-protection. However, the applicability of these findings is questionable as the majority of Americans consume a high-fat (HF) diet.

Objective

The goal of this study was to determine if these beneficial changes in body weight and coronary heart disease (CHD) risk can be reproduced if an HF background diet is used in place of an LF diet during ADF.

Methods

Thirty-two obese subjects were randomized to an ADF-HF (45% fat) or ADF-LF diet (25% fat), which consisted of two phases: 1) a 2-week baseline weight maintenance period, and 2) an 8-week ADF weight loss period. All food was provided during the study.

Results

Body weight was reduced (P<0.0001) by ADF-HF (4.8%±1.1%) and by ADF-LF (4.2%±0.8%). Fat mass decreased (P<0.0001) by ADF-HF (5.4±1.5 kg) and ADF-LF (4.2±0.6 kg). Fat free mass remained unchanged. Waist circumference decreased (P<0.001) by ADF-HF (7.2±1.5 cm) and ADF-LF (7.3±0.9 cm). LDL cholesterol and triacylglycerol concentrations were reduced (P<0.001) by both interventions (ADF-HF: 18.3%±4.6%, 13.7%±4.8%; and ADF-LF: 24.8%±2.6%, 14.3%±4.4%). HDL cholesterol, blood pressure, and heart rate remained unchanged. There were no between-group differences for any parameter.

Conclusion

These findings suggest that an ADF-HF diet is equally as effective as an ADF-LF diet in helping obese subjects lose weight and improve CHD risk factors.

Balance/ type of fat is key in healthy blood cholesterol, as well as quantity. Coconut oil is rich in *short chain* saturates which have different effects to *long chain* saturates from hard animal fats. Butter is surprisingly rich in the same monounsaturate as olive oil! If from grass fed cattle can be a source of omega-3s and CLA (polyunsaturates with anti-inflammatory effects).

Oily fish is the only rich source of *long chain* polyunsaturates omega-3s, which balances out omega-6s (from most nuts, seeds, vegetable oils, grains). The vast majority of westerners eat way too much o-6 and way too little o-3. Dr Mosley recommends a variety and balance of foods, inc. fatty ones.

CHOLESTEROL AND THE BODY Cholesterol is a waxy, fat-like substance that is found in the body and in foods. It is vital for many functions in the body. Cholesterol is important for the structure of cell membranes, the making of hormones, and the maintenance of bones and muscles. The body produces cholesterol. https://www.healthmassive.com/ But we also need to consume it from foods such as eggs, meat, milk, cheese, and some other foods. There is a normal range of cholesterol levels in our blood that indicates what level of cholesterol we should have.
