You have to start looking at health with a healthy mind, fasting, low carb, low calorie, Atkins, high protein will not make you healthy, eating healthy will. you feel me?
You need a low fat diet, high plant carb diet, does that not make more sense to you? carbs are what humans need, our brains use 40-60% of our daily intake of glucose.
the body prefers to burn glucose since it is a cleaner fuel, It hates turning it into fat. On the other hand fat is fat.. our bodies store it so well, if they took a needle and took a sample, they could tell what foods you ate.
Foods that you think are high carb like, pizza, cookies, donuts.. are actually high fat.
Stick to whole plant foods like: yams, plantain, brown rice, bean/peas/legumes, lentils, quinoa, oats, wholewheat pasta/cous cous, sweet potatoes, parsnips, leafy greens, veggies and fruits!
Get your healthy oils from Avocados, nuts like walnuts, and seeds like flax, chia and pumkin.
These foods are great for you and in the right combos form almost any meal you can think off.
they provide: phytonutrients, antioxidants, fiber, vitamins and minerals. this also helps control blood glucose levels, and cholesterol levels, reduce inflammation, improve blood flow, feed good gut bacteria and prevent against cancer.
also make sure you are getting enough vitamin D3, and B12, and enough iodine.
