3. Proteins: Good proteins to eat include fish and shellfish, especially varieties packing omega-3 fatty acids. Some of the healthiest seafood you can eat are salmon, arctic char, mackerel, anchovies, and oysters. Don’t forget about plant proteins such as beans, legumes, nuts, and seeds—these foods contain unsaturated fats, fiber, and can add instant texture and flavor to salads or stand alone as satisfying snacks.
All new habits need a plan. Luckily, I had the Keto360 Blueprint (which mapped out how this was all going to go down), Dr. Axe at my disposal for ALL the questions, a Keto360-approved food list, and a husband who agreed to jump on the two-week keto bandwagon with me. (Research shows that having a buddy system will increase your rate of success in fitness, a diet, and even sticking to your New Year's resolutions.) Still, sitting down to figure out my first week of keto diet meals and snacks was daunting. (Side note: I knew that if I was going to succeed at this, I'd have to be able to buy lunch. Luckily, Dr. Axe is totally on board, saying that most café salad bars will have what I need to create a keto meal-a big spinach salad with salmon and avocado, for example.)
One of the diets that implement these principles is the low-carb ketogenic diet. It primarily consists of highly-satiating foods like meat and low-carb vegetables while cutting out all carb-ridden, highly-palatable foods. By eating in this way, most people experience tremendous amounts of fat loss — not because it lowers insulin levels, but because keto dieters tend to eat significantly fewer calories than high-carb dieters without realizing it.
A systematic review of 26 short-term intervention trials (varying from 4-12 weeks) evaluated the appetites of overweight and obese individuals on either a very low calorie (~800 calories daily) or ketogenic diet (no calorie restriction but ≤50 gm carbohydrate daily) using a standardized and validated appetite scale. None of the studies compared the two diets with each other; rather, the participants’ appetites were compared at baseline before starting the diet and at the end. Despite losing a significant amount of weight on both diets, participants reported less hunger and a reduced desire to eat compared with baseline measures. The authors noted the lack of increased hunger despite extreme restrictions of both diets, which they theorized were due to changes in appetite hormones such as ghrelin and leptin, ketone bodies, and increased fat and protein intakes. The authors suggested further studies exploring a threshold of ketone levels needed to suppress appetite; in other words, can a higher amount of carbohydrate be eaten with a milder level of ketosis that might still produce a satiating effect? This could allow inclusion of healthful higher carbohydrate foods like whole grains, legumes, and fruit. 
In fact, he says my already somewhat balanced diet is part of why I didn't experience the keto flu. (Some people report feeling sick to their stomach, irritable, and dizzy, among other flu-like symptoms, for the first few days or even weeks of keto.) People who transition from a very high-carb and high-protein diet to a high-fat diet are more susceptible to these rare but extreme symptoms, he says. This is why he says he built a Feast Phase-when you're adding fats into your diet without really restricting your carbs-into his Keto360 plan as a way to ease your body into ketosis. "If someone is a fairly good eater, and they already do have a moderate amount of fat in their diet-not high fat but moderate-typically they'll transition pretty well," he says.
“The general body of research says that once you have two or more tablespoons a day, you’ll improve your blood pressure, your glucose levels and your good cholesterol,” Flynn says. “But I’ve found that the weight-loss effect comes into play at three tablespoons, so that’s what I recommend. It’s an amazing food – it does all these things that help your body, plus it tastes good.”
